Why is my SSL expiring every 3 months?
Digital certificates, used with the protocol ‘TLS’ (Transport Layer Security, previously known as ‘SSL’ or Secure Socket Layers) establish secure connections between your web server and the browsers visitors use to view your site. They ensure the user’s browser regards your site as authentic and not as a cybersecurity threat ... Read More
SSL/TLS handshake errors & how to fix them
Transport Layer Security (TLS), the successor to the now-deprecated Secure Sockets Layer (SSL), is a security protocol that encrypts data exchanged between two points on the internet (e.g., a web server and a browser). It also authenticates a website's identity. This process begins with a TLS handshake, a critical negotiation ... Read More
10 Holiday Cybersecurity Tips for CISOs
Organizations experience 30% more ransomware attacks during the holiday season, with a 70% average increase in attempted ransomware attacks in November and December compared with January and February.

Elliptic Curve Cryptography Explained
Public key encryption (PKI) uses two different cryptographic keys, a public key and a private key, to encrypt and decrypt data. These complex algorithms use mathematical formulas to generate digital certificates with unique digital identities to secure information. Elliptic Curve Cryptography (ECC) is one method of generating these key pairs ... Read More
SSL Deprecation: Understanding the Evolution of Security Protocols
Secure Sockets Layer (SSL) is a security protocol that enables encrypted digital communications—between a web browser like Google Chrome or Mozilla Firefox and a web server, for example. SSL certificates authenticate the identity of an online entity and secure online communications with that entity. SSL was created in 1995, and ... Read More

TLS 1.2 Handshake vs TLS 1.3 Handshake
Secure communication protocols make the difference between people navigating the internet with confidence and being at the mercy of attackers. Businesses, governments, and other organizations that people trust with their data have a weighty responsibility as protectors of sensitive information. Transport Layer Security (TLS) is a security protocol used when ... Read More
Certificate Authority Hierarchy: How It Works
Android recently issued a list of root certificates that it has added to Android 14. While this move isn't altogether surprising, it’s interesting to note that some root certificates have also been removed from the approved list. These include those from household names in the certificate authority (CA) space, such as ... Read More
Demystifying Public Certificates vs. Private Certificates: Key Pillars of Digital Security
Organizational data is a critical business asset. As cybercrimes against data continue to rise, certificates are indispensable in ensuring data remains secure. Digital certificates serve to authenticate identities and ensure secure communication. From public-facing websites to internal company servers, certificate use is pervasive and acts as the bedrock for establishing ... Read More
