Zero Trust for OT Security: The Last Line of Defense
Quick Summary Traditional firewalls were never designed to meet the unique security needs of Operational Technology (OT) environments. While they are effective at blocking outside threats, once an attacker breaches the perimeter, devices inside remain vulnerable. Real-world incidents like Colonial Pipeline, Triton malware, and ransomware in building automation highlight how attackers exploit insecure OT protocols…

Key Points Comprehensive Vulnerability Mitigation: DOME encrypts all device communications, enforces unique cryptographic identities, blocks unauthorized actions, and prevents lateral movement even on flat networks—addressing risks like unencrypted data, credential hijacking, privilege escalation, and insecure configurations. Zero Trust at the Endpoint: Every enrolled device must authenticate and follow strict, policy-based access rules, ensuring only explicitly…
Read MoreZero Trust Security for Legacy OT Devices
Key Points Legacy OT Challenges: Many older OT systems use insecure protocols, lack modern security features, and have limited hardware resources—making them difficult to protect using traditional cybersecurity methods. Zero Trust Integration Options: Three primary methods exist—device replacement (costly), software-defined networking (limited protection), and security overlays (most effective and non-intrusive), with overlays offering encryption and…
Read MoreHow Zero Trust Enhances the Security of Building Control Systems
Key Points Minimizes Attack Surface: Replaces location-based trust with granular access controls, reducing the chance of a single breach spreading across interconnected BAS components. Prevents Lateral Movement: Uses micro-segmentation to isolate workloads and resources, containing threats within compromised segments. Continuous Verification & Least Privilege: Continuously authenticates and authorizes users/devices while limiting each to only the…
Read MoreZero Trust for OT Security: Cyber Defense Inside the Perimeter
Inside the Perimeter Defense is a Crucial Part of Defense in Depth for OT Security Firewalls for OT Security Perimeter Defense Firewalls are essential components of network security, acting as perimeter defenses that control incoming and outgoing network traffic based on predetermined security rules. However, they are not without their own set of potential security…
Read MoreKey Differences Between Zero Trust OT Security and Traditional IT Security
How is Zero Trust for OT Security Different from Traditional IT Security? Zero Trust for operational technology (OT) security differs significantly from traditional IT security models in several ways. Here are some key differences: Security Method Traditional IT Security Zero Trust OT Security Trust Model – Assumes that everything inside the network can be trusted.…

Read MoreZero Trust – A Virtual Air Gap for OT Security
Air-gapping computer and operational technology (OT) networks is a long-established method of protecting sensitive information and reducing the risk of operational disruption. A growing trend has been to provide connectivity from these networks to the Internet for remote monitoring and control, real-time data, data analysis, predictive maintenance, improving inventory and resource management, achieving faster decision-making,…
Read MoreZero Trust for OT Security – Shields Up vs Damage Report
In the original and newer Star Trek episodes and movies, the captain would order “shields up” or “raise shields” prior to an attack to prevent damage to the USS Enterprise. The shields were some sort of force field of which the physics is never fully described. During or after an attack the captain would request…
