Zecurity Information

Zecurity is redefining cybersecurity for critical infrastructure and operational technology with a fundamentally different approach: prevent unauthorized changes instead of trying to detect every threat. Traditional cybersecurity relies heavily on software, identity, analytics and increasingly AI to determine whether activity is malicious. Zecurity’s patented Hardwall® technology asks a simpler question: “Is this authorized?” Hardwall is a hardware-based cybersecurity platform that creates separate physical paths for read-only and authorized read/write activity. Users and systems can continue to monitor and view protected environments, while unauthorized attempts to change them are physically blocked. Authorized changes occur through a separate controlled path requiring certificate-based authentication, MFA and existing system credentials. The result is system integrity enforced by physics, not software logic. This approach is particularly valuable for critical infrastructure and OT environments where legacy systems, remote access, expanding connectivity and machine-to-machine communications create growing opportunities for unauthorized change. Hardwall: • Prevents unauthorized changes to protected systems • Works alongside existing cybersecurity controls • Protects current and legacy environments without requiring them to be redesigned • Uses firmware that cannot be remotely changed • Provides reporting of blocked attempts • Reduces dependence on constant threat identification and software updates Zecurity’s technology is protected by four U.S. patents and has been validated through millions of unauthorized write attempts across simulated and real-world environments. Our initial focus includes water and wastewater, oil & gas, and other critical infrastructure and OT environments where maintaining control and system integrity is essential.
