Zero Trust for Power Grid & Substations.
SCADA, RTUs, and relay systems across dozens of substations — legacy infrastructure that cannot afford downtime. Agentless Zero Trust enforcement. No disruption to grid operations.
Protect the Grid. Keep the Lights On.
Five capabilities that protect power grid OT — from primary substations to remote RTUs — without touching operational equipment or impacting grid reliability.
Substation OT Protection
Protect RTUs, relays, protection systems, and SCADA at the network level. No agents installed on operational equipment. Grid operations continue uninterrupted.
Distributed Grid Visibility
Automatic discovery across primary substations, secondary substations, and remote sites. Real-time inventory of every connected device across the full grid network.
IT / OT Segmentation
Enforce strict micro-segmentation between SCADA OT and corporate IT networks. Overlay segmentation without restructuring VLANs, re-cabling, or operational changes.
Controlled Remote Access
On-premise bastion host for field engineers and OEM vendors. MFA-enforced, session-scoped, fully logged — no open VPN tunnels into substation control systems.
NIS2, NERC CIP & IEC 62443
Continuous control enforcement for NIS2, NERC CIP, and IEC 62443. Assessment-ready documentation generated on demand for regulatory audits.
Trusted by utilities and critical infrastructure operators.
ski lifts protected operating across terrain ranging from 850 m to 2,353 m — securing distributed infrastructure in harsh conditions.

“Our substations run equipment from four different decades. Trout gave us segmentation and monitoring across all of them without a single firmware update or agent install.”

Common Questions About Power Grid Security.
agents required on RTUs, relays, or SCADA systems. The Access Gate protects grid OT entirely from the network level.
Yes. The Access Gate operates at the network level — 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 installs inline on existing network infrastructure. No re-cabling, no reconfiguration of protection systems, no IP changes. Grid operations continue normally during deployment — no maintenance windows 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 NIS2 (mandatory for energy operators in the EU), 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.
