What is Access Gate ?

Access Gate is a plug-in security and compliance appliance built for industrial networks and critical infrastructure. It protects on-premise servers, IT/OT/IoT equipment, and legacy systems without changing the way your sites operate.

Access Gate deploys alongside your existing machines and creates a controlled access layer around them. It keeps data on site, enforces who can connect, and records what happens, all without rewiring or disrupting your network.

The goal is simple. Give operators a way to secure and certify their on-premise operations and stay aligned with compliance requirements using a single drop-in appliance.
