Zero Trust Across the Rail Network.
Signaling, SCADA, and train control systems — safety-certified infrastructure that cannot be touched. Enforce Zero Trust at the network level. No agents. No requalification. No downtime.
Protect Rail Signaling. No Requalification Risk.
Five capabilities purpose-built for rail — protect interlocking, ATP, and SCADA at the network level without touching safety-certified systems.
Signaling System Protection
Protect interlocking, ATP, and ETCS equipment without installing agents or triggering safety requalification. Network-level enforcement preserves all existing safety certifications.
Distributed Line Visibility
Automatic discovery across control centers, wayside equipment, depots, and stations. Real-time inventory of every connected device across the full rail network.
OT / IT Segmentation
Enforce micro-segmentation between safety OT (signaling, ATP), operational systems (SCADA, depot), and corporate IT — without restructuring VLANs or re-cabling.
Controlled Maintenance Access
On-premise bastion host for OEM vendors and maintenance contractors. MFA-enforced, session-scoped, fully logged — no open VPN into safety-critical signaling networks.
NIS2 & Rail Directive Compliance
Continuous control enforcement for NIS2 transport directives, IEC 62443, and rail-specific security requirements. Assessment-ready documentation on demand.
Trusted by transportation and critical infrastructure operators.
distributed sites protected across harsh operational environments — securing critical infrastructure without agents or downtime.
Trusted by leading companies
“Our BHS was certified five years ago and we couldn't risk requalification. Trout gave us a path to bring services to legacy environments without requalification.”

Common Questions About Rail Security.
requalification events triggered — the Access Gate never touches safety-certified interlocking, ATP, or ETCS equipment.
No. The Access Gate operates at the network level — it never installs agents, modifies configurations, or touches certified interlocking, ATP, or ETCS systems. All safety certifications and type approvals remain fully intact.
The Access Gate creates encrypted overlay networks across control centers, wayside cabinets, stations, and depots. Policy is managed centrally and enforced consistently at every location, including unmanned trackside installations.
Yes. The Access Gate enforces strict micro-segmentation between safety-critical OT (signaling, ATP), operational systems (SCADA, energy management), and corporate IT — without VLAN restructuring or infrastructure changes.
The Access Gate supports NIS2 (mandatory for rail operators in the EU), IEC 62443, and rail-sector security directives. It generates assessment-ready documentation and provides continuous control enforcement.
Yes. The Access Gate installs inline on existing network infrastructure with zero downtime. No service interruptions, no maintenance windows. Deployment happens during normal operations without impacting train services.
