Secure every substation. The grid keeps running.
Power grid cybersecurity for OT
Control who reaches every RTU, relay and SCADA server. Nothing to install, no rewiring, no outage.
Last updated:
Protect the grid without an outage.
Access Gate connects to your existing network. Substations keep running.
See every machine.
Find every machine across primary, secondary and remote substations.
Control who reaches what.
Keep office traffic away from SCADA and protection systems. No VLAN changes.
Reach any machine, securely.
Field engineers and vendors log in with MFA. Every session is scoped and logged.
Prove every audit.
Every connection is logged. Export audit evidence on demand.
The gate is the first service you run, not the last.
Secure your plants today. Control your digitalization tomorrow.
Access Gate puts compute on the wire, next to your assets. Once the gate is in, the same box hosts the services that pull OT in securely: remote access, protocol gateways, DNS and time, historian, update server. Accelerate your digitalization, in control.

Common questions about power grid security.
agents to install on RTUs, relays or SCADA. Access Gate protects grid OT from the network.
Yes. The Access Gate is agentless: it operates at the network level, and no agents are installed on RTUs, relays or any OT device. It protects everything connected to the network, regardless of age, firmware or operating system. Grid operations continue uninterrupted.
No. The Access Gate connects to your existing network rather than cutting into it. No re-cabling, no reconfiguration of protection systems, no IP changes. Grid operations continue normally during deployment, and no maintenance window is required.
The Access Gate creates encrypted overlay networks across all substations, primary, secondary, and remote. Policy is managed centrally and enforced consistently at every site, including unmanned and remotely monitored installations.
The Access Gate supports NERC CIP (North American grid security standard) and IEC 62443 for industrial security. It generates assessment-ready documentation and provides continuous control enforcement.
Yes. The Access Gate operates entirely on-premise with zero cloud dependency. All policies, data, and management remain within your network. It supports air-gapped and isolated substation environments where external connectivity is restricted.
NERC CIP is the set of Critical Infrastructure Protection standards that bulk electric system operators must meet, covering electronic security perimeters, access control, monitoring, and vendor remote access. Access Gate helps enforce and evidence these controls at the network layer: identity-based access to substations and control centers, session logging, and INSM (CIP-015) network monitoring, deployed on-premise without downtime.
