Web applications and APIs now sit at the center of nearly every digital business, and the threat surface has grown in step. Independent industry analysis estimates that API traffic represents more than 70% of all web traffic, that API related security incidents have climbed to roughly one third of reported data breaches, and that more than a third of recent API breaches trace back to Broken Object Level Authorization (BOLA) flaws.

At the same time, the latest AMTSO-certified SecureIQLab Cloud WAAP v4.0 validation found that average complete-security efficacy across the leading enterprise WAAP solutions declined year over year, even as operational efficiency improved slightly. The takeaway for security leaders is straightforward: WAAP capabilities are diverging across the market, and shortlist decisions made in 2022 or 2023 may no longer reflect current efficacy or operational fit.

This guide focuses on the major WAAP vendors that most frequently appear on enterprise shortlists. It draws on independent SecureIQLab testing, recent Forrester, Gartner, KuppingerCole, and IDC research, and verified peer reviews to help security and risk leaders evaluate platforms across modern, multi-cloud, API-heavy environments without reducing the decision to a generic ranked list.

1. Scope and methodology

This comparison focuses on the major WAAP vendors most commonly evaluated by enterprise buyers: Akamai, Cloudflare, F5, Fastly, Fortinet, and Radware, alongside Imperva. It uses three categories of independently sourced evidence:

• Certified independent testing: the 2025 SecureIQLab Cloud WAAP v4.0 CyberRisk Validation, conducted under AMTSO Test ID AMTSO-LS1-TP097, which evaluated 11 enterprise WAAP solutions across more than 1,360 attacks aligned to the OWASP Top 10, OWASP API Security Top 10 2023, MITRE ATT&CK, and the Lockheed Martin Cyber Kill Chain.
• Analyst recognition: the Forrester Wave for Web Application Firewall Solutions (Q1 2025), the Gartner Market Guide for Cloud Web Application and API Protection, the KuppingerCole 2025 Leadership Compass for WAAP, the IDC MarketScape for WAAP, and Gartner Peer Insights ratings as of the date of this article.
• Verified customer reviews: Gartner Peer Insights, PeerSpot, G2, and TrustRadius user ratings, used as a sentiment signal rather than as a ranking input.

Of the seven platforms covered here, four (Akamai, Cloudflare, Fortinet, and Imperva) completed the public SecureIQLab v4.0 cycle, while three of the competitors (F5, Fastly, and Radware) are listed in the SecureIQLab comparative report as “Contact SecureIQLab” rather than appearing with published v4.0 results. For those three vendors, the profiles below rely on Forrester, Gartner, and verified customer review sources, and head-to-head efficacy comparisons should be confirmed through buyer-led testing.

Other WAAP vendors (for example hyperscaler-native services and specialized API-security vendors) may be relevant for specific buyer needs, but they fall outside the major-vendor scope used here. Buyers should treat this guide as one input among several and validate every vendor claim against their own application portfolio during a proof of value.

2. What is WAAP?

Web Application and API Protection (WAAP) is a category defined by Gartner to describe cloud-delivered services that protect web applications and APIs against runtime attacks. Core capabilities typically include a Web Application Firewall (WAF), distributed denial-of-service (DDoS) protection, advanced bot management, API security, and increasingly client-side script protection.

In practical terms, a WAAP platform sits in front of an application (or a portfolio of applications and APIs) and inspects every request, blocking exploits aligned to the OWASP Top 10 and OWASP API Security Top 10, distinguishing legitimate users from automated abuse, absorbing volumetric and Layer 7 denial-of-service traffic, and providing the visibility security teams need to investigate and tune.

For a foundational explainer, see Imperva’s What is a WAAP? Learning Center article at imperva.com/learn/application-security/web-application-and-api-protection-waap/ (set as an internal link on publish).

3. Why WAAP matters now

Three forces are reshaping WAAP buying decisions in 2026:

• API growth is outpacing API security. Independent reporting indicates that API related breaches have moved from a niche concern to roughly a third of all data breaches, while only about one in five organizations rate themselves as highly capable of detecting attacks at the API layer.
• Bots and AI-enabled automation are escalating. Public industry data shows AI-enabled bot activity rising sharply year over year, with credential stuffing, scraping, and inventory hoarding increasingly difficult to separate from legitimate users without sophisticated behavioral analytics.
• Cloud-native deployment is the new default. As more workloads move inside hyperscale clouds, development teams increasingly prefer security that runs natively within the cloud environment rather than alongside it through external routing that can add latency and operational overhead.
• Regulatory pressure is compounding. Frameworks such as PCI DSS 4.0 (client-side protection requirements), DORA, NIS2, and sector-specific rules on operational resilience are pushing application security from a best practice into a documented control requirement.

For security leaders, the business outcomes a modern WAAP must support include reduced breach risk and downtime, faster time to protection for new applications and APIs, audit and compliance readiness, and predictable cost as application portfolios scale.

Independent analyst standing: Forrester Wave WAF Q1 2025

The Forrester Wave groups vendors into Leaders, Strong Performers, and Contenders, a single published designation that reflects the combined strength of each vendor’s current offering, strategy, and customer feedback. Rather than restate Forrester’s underlying sub-scores, the table below shows each covered vendor’s official tier, with a short note on what Forrester emphasized. This analyst recognition complements security-efficacy testing because it weighs roadmap, innovation, integrations, and customer feedback alongside current capabilities.

Vendor	Forrester tier	What Forrester emphasized
Cloudflare	Leader	Strongest current offering of any vendor evaluated; efficiency-focused features; reference customers flagged support as an area to improve.
Akamai	Leader	Strong detection and automation; broad edge and DDoS scale; noted to lag in DevOps and scanning integrations.
Imperva	Leader	Standout Layer 7 DDoS, CISA Secure by Design Pledge signatory, and a unifying platform roadmap; room to improve in DevOps and scanning integrations and UI consistency.
F5	Strong Performer	Built-in web application scanning and a strong API security story; fewer security operations integrations and a steeper learning curve.
Fastly	Strong Performer	Developer- and business-focused vision and pre-deployment rule testing; still building out API security.
Radware	Strong Performer	AI-assisted SOC tooling and tunable detection; fewer out-of-the-box integrations and less flexible reporting.
Fortinet	Contender	Strong API security capabilities and competitive pricing; roadmap less extensive than others, no rule versioning, and rule testing limited to logging mode.

Source: Forrester Wave: Web Application Firewall Solutions, Q1 2025 (published tier designations and findings). Among the seven vendors covered here, three were named Leaders, three Strong Performers, and one a Contender.

A note on tier equivalence: within Forrester’s methodology, vendors positioned in the same tier hold equivalent standing in the evaluation. The three Leaders (Cloudflare, Akamai, and Imperva) are designated by Forrester as Leaders together; vendor-specific sub-criterion scores within the tier do not change the tier-level designation.

Verified peer feedback (G2)

Independent customer ratings on G2 are a useful third complement to certified testing and analyst evaluation, because they reflect the day-to-day operational experience of paying customers. The table below shows the current G2 standing for each covered vendor’s flagship WAF product profile. Review-base sizes vary widely across vendors, so the rating is best read alongside the volume of reviews supporting it; vendors that have not actively claimed and managed their G2 product profile may show smaller review bases and older reviews.

Vendor product (G2 profile)	G2 rating (of 5)	Review base	Notes
Imperva Web Application Firewall (WAF)	4.7	41	Highest G2 rating among the flagship WAF profiles of the seven covered vendors; primarily enterprise reviewers.
F5 BIG-IP Advanced WAF	4.6	24	Strong rating with a focused enterprise review base.
Radware Cloud WAF	4.6	141	Strong rating with the second-largest review base among the seven.
Cloudflare Application Security and Performance	4.5	595	Largest review base in the category overall; review mix skews toward small business segments.
FortiAppSec Cloud	4.4	33	Solid mid-market G2 standing; reflects Fortinet’s consolidated WAAP profile launched after the Forrester Wave Q1 2025 cutoff.
Fastly Next-Gen WAF	4.2	30	Solid mid-market rating; vendor profile noted on G2 as having limited features (managed but not upgraded).
Akamai App & API Protector	4.0	2	G2 explicitly notes that there are not enough reviews to provide buying insight; the product profile is unclaimed by the vendor.

Source: G2 verified user reviews (most recent rating snapshots at time of writing). G2 product profiles do not always cover a vendor’s full WAAP suite, and review bases vary widely; the table compares each vendor’s flagship WAF product profile. See references.

5. Key criteria to evaluate when comparing WAAP solutions

The framework below combines the SecureIQLab v4.0 evaluation model (security efficacy, operational efficiency, Secure by Design and Secure by Default ratings, false positive avoidance) with capability themes emphasized by Gartner and Forrester.

Capability	What to evaluate
Security efficacy	Independently measured coverage of OWASP Top 10 (web), OWASP API Security Top 10 2023, and advanced threats including bots and Layer 7 DDoS. Look for AMTSO-certified results.
API and microservice protection	API discovery (including shadow and undocumented endpoints), schema enforcement, BOLA and broken authentication detection, support for REST, GraphQL, SOAP, WebSockets, and gRPC.
Bot and abuse mitigation	Ability to distinguish legitimate automation from malicious bots, behavioral analytics, device and TLS fingerprinting, defenses against account takeover, scraping, and inventory hoarding.
Runtime and cloud integration	Support for major public clouds, native in-cloud deployment, Kubernetes and service-mesh ingress, edge versus centralized models, multi-cloud and hybrid coverage, CI/CD integration.
Operational efficiency and FP avoidance	Time to protection, tuning effort, automation, analytics, and false positive avoidance under real traffic. In the latest SecureIQLab v4.0 cycle, false positive avoidance ranged from near-perfect at the top of the group to noticeably weaker at the bottom.
Performance and reliability	Latency impact, scalability under load, behavior of failure modes (fail-open vs fail-closed), out-of-path versus inline architecture, published service-level commitments for availability and mitigation time.
TCO and commercial fit	Licensing model (per app, per request, per Mbps), predictability under traffic spikes, alignment with portfolio growth, marketplace availability, integration with existing security and developer toolchains.
Ecosystem and roadmap	Vendor stability, innovation pace, AI assistance, hyperscaler partnerships, SIEM and SOAR integrations, partner ecosystem, support quality reflected in verified customer reviews.

 

6. Five buyer questions to guide WAAP evaluation

Use these five questions as a lightweight evaluation framework. Each maps to one or more of the capability themes above.

1. How well does the platform stop the threats my applications actually face?

Look beyond generic OWASP coverage claims. Ask for AMTSO-certified third-party test results, and verify both web (OWASP Top 10) and API (OWASP API Security Top 10 2023) efficacy. In the latest SecureIQLab v4.0 testing, complete-security results spanned an extremely wide range, from near-complete coverage at the top to less than half of attacks blocked at the bottom, so the spread within a single shortlist can be very large.

2. How deep is the API protection, across all my protocols?

APIs are no longer just REST. SecureIQLab v4.0 testing measured coverage separately across REST, GraphQL, SOAP, WebSockets, and gRPC, and found that coverage varied widely by protocol even within a single vendor, with WebSockets generally the weakest area across the group. Confirm vendor coverage protocol by protocol, not just by headline API score.

3. How effective is bot defense against modern automation and AI-enabled abuse?

Ask vendors how they detect headless browsers, residential proxy traffic, and AI-driven scraping, and how those decisions are made without harming legitimate traffic. In the SecureIQLab bot suite, only a small number of the tested vendors blocked every attack type, so perfect bot defense is a genuine differentiator rather than a baseline.

4. How quickly can my team get to a tuned, low false-positive state?

Operational efficiency and false positive avoidance are tightly linked. In the latest cycle, the strongest vendors avoided essentially all false positives, while the weakest let through enough to translate into meaningfully more alerts per day and substantially more tuning effort for security operations teams. A few points of difference here can mean a very different daily workload.

5. How does the deployment and licensing model align with how my portfolio is growing?

Native in-cloud deployment, edge delivery, and traditional reverse-proxy models produce very different latency, resilience, and onboarding profiles, and per-request, per-Mbps, and per-application licensing produce very different cost curves as traffic scales. Walk through a 24 to 36 month projection with each shortlisted vendor, ideally informed by your own traffic baseline.

7. WAAP Vendor profiles

Each vendor profile below uses the same schema: a neutral summary, a list of capabilities verified from public documentation and independent sources, and a “Consider when” statement. Profiles are presented alphabetically. Capabilities should be re-validated against your specific environment during a proof of value.

Akamai — App & API Protector

Current market status: Publicly traded (NASDAQ: AKAM). Recognized as a Leader in the Forrester Wave: Web Application Firewall Solutions, Q1 2025, and placed in the Leader category of the SecureIQLab 2025 Cloud WAAP v4.0 validation.

Summary

Akamai delivers WAAP from one of the world’s largest edge networks, combining WAF, DDoS, bot management, API security, and client-side controls in its App & API Protector product. In SecureIQLab v4.0, the tested cloud-based deployment was among the strongest in the group on both complete security and operational efficiency, comfortably above the group averages, and avoided essentially all false positives. In the Forrester Wave Q1 2025, Akamai was named a Leader, strong on both current offering and strategy, with reference customers citing strong detection and automation; Forrester noted that Akamai lags in DevOps and scanning integrations and that some prospects weigh its pricing carefully.

Key capabilities

• Edge-delivered WAAP integrated with Akamai’s global CDN and DDoS scrubbing capacity.
• Behavioral bot detection that blocked every attack type in the SecureIQLab v4.0 bot suite.
• API discovery and schema-aware protection for REST and modern protocols.
• Layer 7 DDoS coverage with a perfect result in SecureIQLab v4.0 Layer 7 DoS testing.
• Integration with Akamai’s broader Zero Trust and AI security portfolio.

Consider when

Consider Akamai when your organization needs edge-delivered protection at very large scale, has significant CDN and DDoS requirements alongside WAAP, and wants a vendor with an established global footprint and analyst-recognized leadership.

Cloudflare — Cloudflare WAF (Application Security)

Current market status: Publicly traded (NYSE: NET). Recognized as a Leader in the Forrester Wave: Web Application Firewall Solutions, Q1 2025, with the strongest current-offering position of any vendor evaluated. Placed in the Visionary category of the SecureIQLab 2025 Cloud WAAP v4.0 validation; rated Secure by Default.

Summary

Cloudflare delivers WAAP from a globally distributed programmable network, with strong developer experience, rapid feature velocity, and integrated DDoS, bot management, API gateway, and Page Shield (client-side protection). In SecureIQLab v4.0, Cloudflare’s complete-security result landed around the group average, but it blocked every bot and Layer 7 DoS attack type and avoided nearly all false positives; API coverage was uneven, with strength in SOAP and gRPC and notable weakness in REST and WebSockets in the tested configuration. In the Forrester Wave Q1 2025, Cloudflare was named a Leader and posted the strongest current offering of any vendor evaluated; Forrester credited an efficiency-focused feature set and noted that reference customers flagged customer support as an area to improve.

Key capabilities

• Cloud-native WAF integrated with Cloudflare’s CDN, DDoS scrubbing, and developer platform.
• Programmable security policies and edge workers for custom logic.
• Bot management that blocked every attack type in the SecureIQLab v4.0 bot suite.
• Page Shield client-side protection aligned to PCI DSS 4.0 requirements.
• Strong developer experience and rapid product release cadence.

Consider when

Consider Cloudflare when your organization values developer-led security, rapid time to deploy, and a unified edge platform across CDN, DDoS, and application protection. Plan to validate API coverage by protocol against your specific traffic mix during a proof of value.

F5 — Distributed Cloud WAAP

Current market status: Publicly traded (NASDAQ: FFIV). Named a Strong Performer in the Forrester Wave: Web Application Firewall Solutions, Q1 2025. Not part of the public 2025 SecureIQLab v4.0 published cycle (listed as Contact SecureIQLab in the comparative report).

Summary

F5 brings deep WAF heritage from BIG-IP Advanced WAF and a multi-acquisition portfolio (Volterra, Shape Security), assembled into the Distributed Cloud (XC) WAAP service. F5 is often shortlisted by organizations with significant existing F5 application delivery and security investments and a need to span data center, multi-cloud, and SaaS-delivered WAAP. In the Forrester Wave Q1 2025, F5 was named a Strong Performer, solid on both current offering and strategy; Forrester credited built-in web application scanning (via its Heyhack acquisition) and a strong API security story, while noting fewer security operations integrations and a steep learning curve cited by reference customers. Because F5 did not appear in the public SecureIQLab v4.0 dataset, comparative efficacy claims should be validated through buyer-led testing.

Key capabilities

• Distributed Cloud WAAP delivered as a SaaS layer across multi-cloud and edge.
• Behavioral bot defense lineage from Shape Security.
• API security including discovery and schema validation.
• Hybrid deployment alongside BIG-IP Advanced WAF appliances and virtual editions.
• Strong fit for hybrid enterprises with existing F5 footprints.

Consider when

Consider F5 when your environment already standardizes on F5 application delivery and security infrastructure, when hybrid (data center plus SaaS) WAAP is required, and when buyer-led testing can fill the absence of comparable public SecureIQLab v4.0 data.

Fastly — Next-Gen WAF

Current market status: Publicly traded (NYSE: FSLY). Recognized as a Strong Performer in the Forrester Wave: Web Application Firewall Solutions, Q1 2025 (vision described by Forrester as developer- and business-focused). Not part of the public 2025 SecureIQLab v4.0 published cycle (listed as Contact SecureIQLab in the comparative report).

Summary

Fastly’s WAF is built on the Signal Sciences engine and is closely integrated with Fastly’s programmable edge platform. The product appeals to developer-led organizations that want deep observability into request decisions, the ability to test rules before deployment, and tight CI/CD integration. The absence of Fastly from the SecureIQLab v4.0 public cycle means head-to-head efficacy comparison against the 11 tested vendors must come from internal testing.

Key capabilities

• Signal Sciences detection engine with detailed signal-based decisioning.
• WAF Simulator for testing rules prior to production deployment.
• Native integration with Fastly’s programmable CDN.
• API security features that have continued to expand in 2024 and 2025.
• Strong reported partner-style customer relationships.

Consider when

Consider Fastly when application security is closely coupled to a developer-first delivery culture, when observability and pre-deployment rule testing are priorities, and when the lack of public SecureIQLab v4.0 data can be supplemented by internal validation.

Fortinet — FortiWeb

Current market status: Publicly traded (NASDAQ: FTNT). Named a Contender in the Forrester Wave: Web Application Firewall Solutions, Q1 2025, and placed in the Leader category of the SecureIQLab 2025 Cloud WAAP v4.0 validation.

Summary

FortiWeb is Fortinet’s WAAP, available as VM, AMI, container, and SaaS, and integrated with the broader Fortinet Security Fabric. The two independent sources frame Fortinet differently. In SecureIQLab v4.0, FortiWeb posted the strongest complete-security result among the tested platform vendors, with high operational efficiency and near-perfect false positive avoidance (its bot defense blocked three of the four attack types). In the Forrester Wave Q1 2025, Fortinet placed in the Contender tier, the only covered vendor below the Strong Performer band, with developing positions on both current offering and strategy. Forrester noted a roadmap less extensive than others in the evaluation, an absence of rule versioning, rule testing limited to logging mode, and limited compliance and performance reporting, while crediting strong API security capabilities and competitive pricing.

Key capabilities

• WAAP available as virtual machine, AMI, container, and SaaS.
• Integration with Fortinet Security Fabric (FortiGate, FortiAnalyzer, FortiSIEM).
• Machine learning models for traffic profiling and threat detection.
• API security capabilities including anomaly detection, PII labeling, and gRPC support (per Forrester).
• April 2024 Google Cloud Technology Partner of the Year award in application security.
• Strongest complete-security result among the SecureIQLab v4.0 tested platform vendors.

Consider when

Consider FortiWeb when your organization is standardized on the Fortinet Security Fabric, when integrated network and application security is a priority, and when a competitively priced option within a large security platform is the goal. Buyers prioritizing rule lifecycle management (versioning, safe rule testing outside logging mode) or breadth of strategy and roadmap should weigh the Forrester findings and validate these areas during a proof of value.

Imperva (part of Thales) — Web Application and API Protection

Current market status: Now part of Thales (acquired December 2023). Recognized as a Leader in the Forrester Wave: Web Application Firewall Solutions, Q1 2025, and the KuppingerCole 2025 Leadership Compass for WAAP. Placed in the Leader category of the SecureIQLab 2025 Cloud WAAP v4.0 validation (the fourth consecutive cycle) and awarded the Secure by Default rating.

Summary

Imperva delivers a unified WAAP combining Cloud WAF, Advanced Bot Protection, API Security, DDoS Protection, Client-Side Protection, Account Takeover Protection, and CDN under one platform, available as SaaS, on-premises, or deployed natively inside hyperscale clouds. In SecureIQLab v4.0, Imperva was among the strongest in the group on both complete security and operational efficiency, well above the group averages, and notably achieved perfect 100% results in bot defense, Layer 7 DoS, and false positive avoidance, a combination of high efficacy and full false-positive discipline that few vendors matched. In the Forrester Wave Q1 2025, Imperva was named a Leader, strong on strategy and solid on current offering. Forrester highlighted Imperva’s Layer 7 DDoS, its signing of the CISA Secure by Design Pledge, and a roadmap that integrates its application security offerings into a unified platform, while noting room to improve in out-of-the-box DevOps and scanning integrations and in some UI consistency.

Key capabilities

• Unified WAAP platform across SaaS, on-premises, and cloud-native deployment.
• Native in-cloud deployment for AWS, Microsoft Azure, and Google Cloud, with Imperva for Google Cloud (available on Google Cloud Marketplace) inspecting traffic inside the Google Cloud network via Service Extension and Private Service Connect, and onboarding without DNS, SSL, or routing changes.
• Advanced Bot Protection with behavioral analytics and fingerprinting; blocked every bot attack type in SecureIQLab v4.0 testing.
• API Security with discovery, schema-based protection, and BOLA detection; API protocol coverage well above the tested-group average.
• DDoS Protection with industry SLA commitments; perfect result in SecureIQLab v4.0 Layer 7 DoS testing.
• Client-Side Protection aligned to PCI DSS 4.0 magecart and script-protection requirements.
• Perfect 100% results in bot defense, Layer 7 DoS, and false positive avoidance in the SecureIQLab v4.0 cycle; Secure by Default rating per CISA-aligned criteria.

Consider when

Consider Imperva when your organization needs unified WAAP across multi-cloud and hybrid environments, when deep API security and bot defense are required alongside core WAF and DDoS, when low operational burden and very high false-positive avoidance are priorities, and when cloud-native deployment inside AWS, Azure, or Google Cloud is on the roadmap.

Radware — Cloud Application Protection Service

Current market status: Publicly traded (NASDAQ: RDWR). Recognized as a Strong Performer in the Forrester Wave: Web Application Firewall Solutions, Q1 2025. Not part of the public 2025 SecureIQLab v4.0 published cycle (listed as Contact SecureIQLab in the comparative report).

Summary

Radware’s Cloud Application Protection Service combines WAF, bot management, API protection, and DDoS, with continued investment in AI-driven detection and SOC automation tooling. Radware’s heritage in DDoS protection makes it a frequent shortlist option for organizations whose risk profile is heavily weighted to availability attacks. In the Forrester Wave Q1 2025, Radware was named a Strong Performer, strong on strategy and solid on current offering; Forrester credited its AI SOC Xpert tool and tunable detection models, while noting fewer out-of-the-box integrations and reference-customer feedback that reporting could be more flexible. Comparable SecureIQLab v4.0 data is not publicly available for this cycle.

Key capabilities

• Cloud Application Protection Service combining WAF, bots, API, and DDoS.
• Strong DDoS protection heritage.
• AI-assisted SOC tooling for application protection.
• Hybrid and cloud deployment options.
• Forrester recognition for detection models and pricing transparency in Q1 2025.

Consider when

Consider Radware when DDoS exposure is a primary driver, when AI-assisted SOC tooling is valued, and when the absence of public SecureIQLab v4.0 data can be addressed through internal testing.

8. Why Imperva stands out for unified, cloud-native WAAP

Imperva’s differentiation is grounded in four architectural realities that buyers can verify in their own environments and through independent testing.

• Unified WAAP rather than assembled WAAP. Imperva’s Cloud WAF, Advanced Bot Protection, API Security, DDoS Protection, Client-Side Protection, Account Takeover Protection, and CDN are delivered as one platform rather than a portfolio of acquired and integrated products. The result is consistent policy, telemetry, and analytics across the entire application protection surface.
• Validated efficacy with very low operational burden. In the latest AMTSO-certified SecureIQLab v4.0 cycle, Imperva paired among the strongest complete-security and operational-efficiency results in the group with perfect 100% results in false positive avoidance, bot defense, and Layer 7 DoS. Few vendors in the tested set combined top-tier efficacy with that level of false-positive discipline.
• Deployment flexibility, including native cloud integration. Imperva can be deployed as SaaS, on-premises, or natively inside hyperscale clouds. Imperva for Google Cloud, available on Google Cloud Marketplace, inspects traffic inside the Google Cloud network using Service Extension and Private Service Connect, and onboards without DNS, SSL, or routing changes. This native, in-cloud direction extends across AWS, Azure, and Google Cloud, and reflects a broader roadmap of running enterprise-grade WAAP inside hyperscale infrastructure rather than alongside it through external routing.
• Aligned to CISA Secure by Design. Imperva earned the SecureIQLab Secure by Default rating in the same cycle, reflecting hardened defaults and the ability to protect newly deployed applications without extensive manual tuning.

No single platform is the right answer for every environment. Buyers whose dominant requirement is a single edge platform unifying CDN, application protection, and a developer-centric workflow, or whose primary driver is the deepest possible DDoS scrubbing capacity, will want to weigh those needs explicitly. The most reliable approach is to validate any shortlist, including Imperva, against your own threat model, traffic patterns, and cloud footprint during a proof of value.

9. How to choose the right WAAP platform

Choosing a WAAP platform should start with your operating reality, not the vendor list. The matrix below maps the most common dominant security gap to the WAAP capabilities buyers should prioritize during evaluation.

If your biggest gap is…	Prioritize…
API exposure and BOLA-style abuse	API discovery (including shadow APIs), schema enforcement, behavioral analytics, BOLA detection, broad protocol coverage (REST, GraphQL, SOAP, WebSockets, gRPC).
Bot abuse and account takeover	Behavioral bot detection, device and TLS fingerprinting, real-time risk scoring, integration with fraud and identity controls.
Volumetric and Layer 7 DDoS	Always-on DDoS scrubbing capacity, time-to-mitigate SLAs, AMTSO-validated Layer 7 DoS scores.
PCI DSS 4.0 client-side scripts	Client-side protection that inventories scripts, detects unauthorized modification, and produces auditable evidence.
Operational overhead and tuning effort	High Secure by Default scores, high independent false positive avoidance scores, automated policy generation, and analyst-recognized ease of management.
Multi-cloud, hybrid, and cloud-native coverage	Consistent policy and telemetry across AWS, Azure, GCP, and on-premises; native in-cloud deployment options; CDN-agnostic delivery; marketplace availability.
Developer-led delivery culture	CI/CD integration, infrastructure-as-code support, rule-testing tooling, programmable edge.

Proof-of-value checklist

• Validate independent efficacy scores against your own application portfolio and threat model.
• Test API protection across every protocol you actually use (not just REST).
• Measure tuning effort and false positive rates under real traffic for at least two weeks.
• Confirm Layer 7 DDoS and bot defenses against representative attack patterns and adversarial automation.
• Test the deployment model you intend to run in production, including native in-cloud deployment where relevant.
• Walk through licensing across a 24 to 36 month projection that includes anticipated traffic and portfolio growth.
• Verify SIEM, SOAR, identity, and developer-tool integrations against your existing stack.
• Review verified peer feedback (Gartner Peer Insights, PeerSpot, G2, TrustRadius) for unfiltered operational reality.

10. Frequently asked questions

What are the best WAAP solutions in 2026?

There is no single best WAAP for every organization; the right platform depends on your threat profile, API footprint, and cloud architecture. Among the major vendors most often shortlisted by enterprises, Akamai, Cloudflare, and Imperva were named Leaders in the Forrester Wave: Web Application Firewall Solutions, Q1 2025, while Akamai, Fortinet, and Imperva placed in the Leader category of the AMTSO-certified SecureIQLab Cloud WAAP v4.0 validation. In that cycle, Imperva combined among the strongest security efficacy in the group with perfect 100% results in bot defense, Layer 7 DoS, and false positive avoidance. Validate any shortlist against your own traffic during a proof of value.

What is the difference between a WAF and a WAAP?

A Web Application Firewall (WAF) inspects and filters HTTP traffic to block common web exploits such as those in the OWASP Top 10. Web Application and API Protection (WAAP) is the broader, cloud-delivered category defined by Gartner that pairs a WAF with additional runtime defenses, typically DDoS protection, advanced bot management, API security, and client-side script protection. In other words, the WAF is one component inside a modern WAAP platform.

Which major WAAP vendors were named Leaders in the most recent Forrester Wave for WAF Solutions?

In the Forrester Wave: Web Application Firewall Solutions, Q1 2025, which evaluated 10 providers across 22 criteria, the vendors covered in this guide were placed as follows: Akamai, Cloudflare, and Imperva were named Leaders; F5, Fastly, and Radware were named Strong Performers; and Fortinet was named a Contender.

Which of the vendors covered here completed the most recent SecureIQLab Cloud WAAP testing?

Of the seven platforms covered here, four completed the public SecureIQLab v4.0 cycle: Akamai, Cloudflare, Fortinet, and Imperva. Akamai, Fortinet, and Imperva were placed in the Leader category. F5, Fastly, and Radware are listed as Contact SecureIQLab in the comparative report and did not appear with published v4.0 results.

Why does API protocol coverage matter so much in 2026?

API traffic now accounts for more than 70% of all web traffic, and independent industry reporting links roughly a third of recent data breaches to APIs, with about 35% of API breaches tied to Broken Object Level Authorization (BOLA). Modern WAAPs need to cover REST, GraphQL, SOAP, WebSockets, and gRPC; independent testing has shown wide variance across protocols even within a single vendor’s product.

What does native cloud deployment add over traditional WAAP delivery?

Native in-cloud deployment lets a WAAP inspect traffic inside the cloud provider’s own network rather than routing it externally, which can reduce latency and operational overhead and avoid changes to DNS, SSL, or routing. Imperva for Google Cloud, for example, uses Google Cloud Service Extension and Private Service Connect to operate inside the Google Cloud network, and Imperva offers native deployment across AWS, Azure, and Google Cloud.

What independent WAAP testing standards should I trust?

Look for testing conducted under the Anti-Malware Testing Standards Organization (AMTSO) framework. The SecureIQLab Cloud WAAP v4.0 methodology used in this guide is AMTSO-certified (AMTSO-LS1-TP097). Pair it with analyst evaluations (Forrester, Gartner, KuppingerCole, IDC) and verified peer reviews.

How should I treat vendor-supplied competitive content during evaluation?

Treat vendor-produced competitive comparisons as marketing inputs rather than evidence. Anchor evaluation on AMTSO-certified independent testing, recent analyst reports, and verified peer reviews, and confirm specific claims through your own proof of value.

11. Choose your next step

Strong WAAP decisions combine three things: independent testing data, analyst guidance, and a proof of value run on your own traffic. As next steps, security leaders typically benefit from running a quick application portfolio baseline (top 20 apps and APIs by risk), executing an internal red-team exercise against current controls, and shortlisting two to three vendors for parallel proof of value testing across the dimensions outlined above.
