Secure accesswithout compromise.
Hardware-enforced remote access to the grids, plants, and control systems that run modern life, without trading away operational continuity or security. The same boundary now lets utilities put AI to work on the grid without putting the grid within AI's reach.
The systems that keep the lights on were never built to face the internet. So we keep the internet away from them, across a physical break no packet can cross.
The way you reach those systems has become the way attackers reach them too.
All-or-nothing access turns one breach into a blackout
VPNs and tools like TeamViewer were built for convenience, not for substations and treatment plants. They hand a remote engineer a route onto the operational network, and that same route is exactly what an attacker takes once a credential leaks.
Access is all-or-nothing. Once someone is in, they can reach far more than the one system they came to service, and a single compromised laptop becomes a path straight to physical infrastructure.
Hardware-enforced remote access for operational technology
Zeroport replaces the tunnel with a hardware-enforced physical air-gap. Every session crosses a one-way optical break: there is no IP route between the remote operator and your control systems, so there is nothing for malware or stolen credentials to ride in on.
Access is granted at the asset level: a vendor reaches the one pump, PLC, or HMI they are authorized for, and nothing else. No broad network exposure, no lateral path; isolation enforced in silicon, not policy.
The grid is already a target
of ransomware attacks on energy and water infrastructure originate from exploited internet-facing vulnerabilities, the exact exposure a non-IP bridge removes.
inbound IP routes into the control network. The break in the wire cannot carry a packet, so it cannot carry an exploit.
access by design: each session reaches one authorized system, never the network behind it.
Built for howutilities actually operate
The same hardware boundary covers every way the outside world needs to reach your OT: vendors, maintenance crews, segmented sites, and air-gapped operators who still need the web.
Third-Party Vendor Access
Grant outside integrators and OEMs time-limited, asset-specific access to the exact system they are servicing. The window closes when the work is done, and no standing connection is ever left behind.
ICS & OT Remote Maintenance
Engineers diagnose and service PLCs, RTUs, and HMIs in real time across the physical break: full interactive control with no IP path that could be turned back against the plant.
AI for Grid Operations, Held at the Boundary
Run inspection, optimization, and maintenance AI against control systems across the physical break: pixels out, keystrokes in, deterministic rules pinning every action to the sanctioned asset. If the model drifts, the session dies at the boundary, not in the substation.
Segmented Networks
Keep IT and OT genuinely separate. A non-IP boundary between zones stops lateral movement cold: a breach in one segment has no route to traverse into the operational environment.
Keep operations running.Keep attackers out.
See how hardware-enforced, asset-level access lets vendors and engineers reach critical systems, with no IP route for anyone else to follow.
