Secure your airport systems. Certified systems stay untouched.
Airport cybersecurity for OT
Control who reaches baggage, building and flight-display systems. Nothing is installed on them, so nothing needs requalification.
Last updated:
Protect certified systems without requalification.
Access Gate connects to your existing airport network. BHS, FIDS and access control stay as they are.
See every machine.
Find every machine across terminals, concourses and cargo areas, from check-in kiosks to airside controls.
Control who reaches what.
Keep airside, landside and passenger systems apart. No VLAN changes.
Reach any machine, securely.
BHS vendors and FIDS integrators 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 airport security.
requalification events triggered by deployment. Access Gate never touches certified BHS, FIDS or gate control systems.
No. Access Gate works at the network level. It never installs agents, changes configurations or touches certified BHS PLCs, FIDS servers or gate systems. All certifications and type approvals stay intact.
Yes. Access Gate adds Zero Trust access, MFA, session logging and micro-segmentation to legacy and air-gapped airport OT. It runs fully on-premise, with no cloud dependency.
The Access Gate enforces micro-segmentation between airside OT networks, passenger-facing systems, and corporate IT, without restructuring VLAN or re-cabling. Policy is managed centrally and enforced at every connection point.
The Access Gate supports IEC 62443 for industrial security, NIST SP 800-82 for OT, and aviation-sector directives. It generates assessment-ready documentation and provides continuous control enforcement.
Yes. Access Gate connects to your existing network with zero downtime. No maintenance window, no flight disruption. It is installed during normal operations, day or night.
Airport cybersecurity protects the OT that keeps terminals running: baggage handling (BHS), building management (BMS), flight information displays (FIDS), and access control. Access Gate secures these systems at the network layer with Zero Trust access and segmentation, meeting TSA airport requirements, without touching or requalifying certified operational equipment.
