Secure your signaling and train control. Certified systems stay untouched.
Railway cybersecurity for OT
Control who reaches signaling, SCADA and train control. Nothing is installed on them, so nothing needs requalification.
Last updated:
Protect rail signaling without requalification.
Access Gate connects to your existing rail network. Interlocking, ATP and SCADA stay as they are.
See every machine.
Find every machine across control centers, wayside cabinets, depots and stations.
Control who reaches what.
Keep signaling and train control apart from SCADA and office IT. No VLAN changes.
Reach any machine, securely.
OEMs and maintenance contractors log in with MFA. Their VPN or 4G link ends at the gate.
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 rail security.
requalification events triggered. Access Gate never touches safety-certified interlocking, ATP or ETCS equipment.
No. Access Gate works at the network level. It never installs agents, changes configurations or touches certified interlocking, ATP or ETCS systems. All safety certifications and type approvals stay 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 IEC 62443, NIST SP 800-82, and rail-sector security directives such as the TSA security directives for rail. It generates assessment-ready documentation and provides continuous control enforcement.
Yes. Access Gate connects to your existing network rather than cutting into it, with zero downtime. No service interruption, no maintenance window. Trains keep running during deployment.
Railway cybersecurity protects the OT behind train control and operations: signaling, interlockings, CBTC, and trackside SCADA. These systems are safety-critical and often cannot be patched or taken offline, so Access Gate adds Zero Trust access, segmentation, and audit at the network layer, aligned with TS 50701 and IEC 62443, without requalifying certified equipment.
