Zero Trust: The Secret Sauce Behind Breach Readiness

For years, organizations have invested heavily in firewalls, perimeter sensors, and intrusion detection to keep attackers at bay. But as we continue to see each day, adversaries always manage to slip past these defenses. And the problem doesn’t lie in the technology but in the way we operate them.

Enter Zero Trust – The Only Way to Operate Cyber Defense

Traditionally, once a user crossed the initial network perimeter, they were trusted to be valid users. But with credential theft, phishing, and impersonation on the rise, it is impossible to determine if the user is who they claim to be just because they crossed the initial perimeter. The Zero Trust Architecture, first evidenced in how firewall rules began with “deny all” and documented by Forrester, expects continuous verification using multiple parameters for every user, device, or software request—every time it attempts to access something.

The NIST Zero Trust standards, NIST 800-207 and 1800-35, considered the original guidelines for how a Zero Trust Architecture needs to be operated, espouse three approaches to establishing Zero Trust: Enhanced Identity Governance, Microsegmentation, and Software-Defined Perimeters (SDP).

Adoption by the U.S. Department of Defense

Later, the U.S. Department of Defense (DoD) developed a Zero Trust Reference Architecture, which defined five major Zero Trust tenets.  

• Assume a Hostile Environment. There are malicious personas both inside and outside the environment. All users, devices, applications, environments, or other network participants (often referred to as NPEs or Non-Privileged Entities) are considered untrusted by default.
• Presume Breach. There are hundreds of thousands of attempted cybersecurity attacks against DoD environments every day. Consciously operate and defend resources with the assumption that an adversary is present within your environment. Enhance scrutiny of access and authorization decisions to improve response outcomes.
• Never Trust, Always Verify. Deny access by default. Every device, user, application/workload, and data flow is authenticated and explicitly authorized using least privilege, multiple attributes, and dynamic cybersecurity policies.
• Scrutinize Explicitly. All resources are consistently accessed in a secure manner using multiple attributes (both dynamic and static) to derive confidence levels for contextual access. Access to resources is conditional and can dynamically change based on actions and confidence levels resulting from those actions.
• Apply Unified Analytics. Apply unified analytics for data, applications, assets, and services (DAAS) to include behavioral analysis and log each transaction. 

The U.S. Department of Defense also identified seven “pillars” to guide relevant decision-makers in directing investment into these areas in a bid to adopt Zero Trust Architecture. They then incorporated all these into a highly complex guideline to ensure Zero Trust adoption complies with the standard. However, this also led to the perception that Zero Trust Architecture is too difficult to implement and operate, causing many commercial organizations to stay away.

The core of Zero Trust Architecture, however, never changed. These fundamentals form the basis of how enterprises can implement cyber defense to #bebreachready. Addressing these three approaches in unison is vital to adopting Zero Trust Architecture while maximizing the value of your existing security investments.

ColorTokens Provides All Three Zero Trust Pillars

ColorTokens is the only solution that pervasively unifies Enhanced Identity Governance, Microsegmentation, and Software-Defined Perimeters under a single platform—across data centers, industrial control systems (OT), and cloud-based infrastructures—by seamlessly using a single point of control to verify every request. Whether it’s from a human user, a machine, or a software process, the SaaS-based ColorTokens Xshield Policy Engine ensures secure access.

The ColorTokens Policy Engine acts as an administrator to: 

• Continuously Verify the identity of every information requester—whether they are connecting to local compute, user endpoints, legacy systems, OT/ICS, cloud workloads, or Kubernetes clusters.
• Enforce Policies Pervasively through Policy Enforcement Points (PEPs) across your infrastructure. If something looks suspicious, it is contained or blocked immediately.
• Unify All Three Zero Trust Approaches by bridging Enhanced Identity Governance, Microsegmentation, and Software-Defined Perimeters in a single, tightly integrated framework.

 
The Forrester’s Q3 Wave Report recognizes ColorTokens as a Leader for its strengths in OT, healthcare, IoT, and incident response capabilities. Our Xshield Enterprise Microsegmentation Platform was also featured in GigaOm’s Radar for Microsegmentation and Constellation Research’s Shortlists for Microsegmentation.  

Achieving Breach Readiness with Unified Zero Trust

So, how does this all translate into true breach readiness? By consolidating the three Zero Trust pillars under one Policy Engine, you gain: 

• Real-Time Visibility Across All Environments 
  It’s often blind spots, not the perimeter, that fail first. When every device, user, and workload is continuously verified, you can spot unusual activity early and prevent small issues from escalating into full-blown crises.
• Seamless Containment, Not Just Alerts 
  Endless notifications can be overwhelming. The Policy Engine doesn’t just warn you—it isolates any suspicious request or compromised machine automatically, so you’re not forced to shut down entire segments in a panic.
• Maintaining Core Operations Under Attack 
  If a segment is compromised, automated microsegmentation and pervasive policy enforcement allow you to quarantine infected areas without disrupting the rest of the organization—like a fire door that prevents a blaze from consuming an entire building.
• Streamlined Compliance and Governance 
  With centrally managed, auditable policies, adhering to NIST and other mandates becomes a straightforward process. This reassures both leadership and regulators that your security posture is strong and well-managed.
• A Cyber Resilient Future 
  Threats evolve daily. Because the Policy Engine adapts dynamically—adjusting rules as your environment scales or vulnerabilities emerge—your Zero Trust framework remains effective against advanced persistent threats (APTs) and novel malware strains.

Wrapping It Up

A truly breach-ready posture starts with accepting that attackers will eventually slip through even the strongest perimeter. Adopting all three Zero Trust pillars under a single platform equips your organization with continuous verification, automated isolation, and real-time insights to contain threats and keep critical operations running.

No more reactive security or chaotic shutdowns. With ColorTokens, you lock down malicious traffic at its source, protect key assets with precision, and maintain business momentum. That’s how you achieve a comprehensive Zero Trust Architecture and real, lasting breach readiness to face today’s cyber threats head-on.
