US utilities: two deadlines on the calendar.
NERC CIP-003-9
New enforcement rules for electric utilities took effect April 1. See how Access Gate covers CIP-002 through CIP-015.
NY Water Compliance Guide
NY water utilities face DOH (drinking water, January 1, 2027) and DEC (wastewater, March 11, 2027) compliance deadlines. EFC SECURE grant funding, the 12-step checklist, and NIST CSF 2.0 mapping in one place.
Up in a day, no outage.
Access Gate connects to your existing network. No re-cabling, no service impact.
Nothing to install on field machines.
RTUs, relays and SCADA stay as they are. Access Gate works from the network.
Runs fully on-premise.
No cloud dependency. Ready for isolated and air-gapped sites.
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.
Trusted by utilities and critical infrastructure operators.
distributed field assets secured under one centralized Zero Trust control, spanning terrain from 850 m to 2,353 m in altitude, in harsh remote 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 utility security.
Agents required on field equipment. The Access Gate protects SCADA, RTU, and ICS devices entirely from the network level.
Yes. The Access Gate is agentless: it operates at the network level, and no agents are installed on endpoints. It protects SCADA, RTU, PLCs, relays, and any device connected to the network, regardless of age, firmware, or operating system.
No. The Access Gate connects to existing infrastructure. There is no re-cabling, no IP changes, and no outage required. It deploys alongside your current architecture during normal operations.
The Access Gate creates encrypted overlay networks across all sites, substations, treatment plants, pumping stations, and control centers, with overlay micro-segmentation between corporate IT and operational networks. Policy is managed centrally and enforced consistently at every location.
The Access Gate supports NERC CIP for electric utilities, AWIA risk and resilience requirements for water systems, and IEC 62443. It provides continuous control enforcement, documentation generation, and audit-ready reporting.
The built-in bastion host provides a controlled gateway for vendors and field engineers. Each session requires MFA, is scoped to specific systems, time-limited, and fully recorded. It works with your VPN or 4G link and leaves no persistent access.
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 utility environments.
SCADA security protects the supervisory control and data acquisition systems that run utility operations: RTU, PLCs, HMIs, and the control servers behind them. Because these systems often cannot be patched or run agents, Access Gate secures them at the network layer with Zero Trust access, segmentation, and monitoring, deployed on-premise with no downtime to the grid or plant.
