What Zero Trust means for critical infrastructure

Three principles for a more deliberate approach to access and protection.

Verify explicitly

Access decisions should consider the user, device, and relevant context. A trusted location alone does not provide a complete picture. Explicit verification helps an organization understand who or what is requesting access to its systems.

Use least-privilege access

Permissions should match the needs of the task. Reducing unnecessary access helps limit exposure while keeping essential activities possible. For operational environments, these decisions need to account for continuity and safety requirements.

Plan for the possibility of a breach

Assuming breach encourages teams to consider how compromise could affect connected systems. Transit Sentinel helps assess the current environment and develop a practical roadmap for implementing Zero Trust principles.
