Xertified Hide & Protect makes critical IT, OT and IoT assets invisible on the network. Devices do not respond to scans, pings or connection attempts from unauthorised parties. They simply do not exist — until a valid, policy-matched Key presents itself.

Obscurity stopped being protection
AI-assisted scanners identify exposed OT devices, fingerprint firmware and cross-reference known CVEs in minutes. A controller once obscure through sheer irrelevance is now trivially discoverable.
The exploitation window has collapsed
The time between a CVE being published and actively exploited in OT environments is now measured in days, not months.
Patching is not a realistic answer
Downtime is unacceptable, vendor support is limited, and many devices have no patch path at all. The vulnerability stays open because closing it is not an option.
If attackers cannot see it, they cannot touch it
A Lock goes inline, the device stays untouched
Installed adjacent to the protected asset with no modification to the device and no changes to the existing network.
Default deny on everything
The Lock intercepts all traffic destined for the asset and answers nothing. Unauthenticated connection attempts receive no response at all.
Only a valid Key opens it
A unique PKI certificate identity, issued to an authorised user or system. When Key and Lock match and policy permits, an encrypted tunnel is established.
The session closes, invisibility returns
Every session is logged. When the policy window ends the connection terminates and the device disappears again.
A device that does not respond to scans cannot be fingerprinted. A device that cannot be fingerprinted cannot be matched against a CVE database.
What you get
Network invisibility
No response to pings, port scans or any unauthenticated attempt. Invisible to automated reconnaissance, including AI-assisted scanners.
Over 90% less patching pressure
A hidden device has no exposed surface for CVEs to target — extending the operational lifespan of legacy equipment without adding risk.
Stops lateral movement
Even after a network breach, protected devices are not visible from compromised positions — removing the paths that make breaches catastrophic in OT.
No modification to the asset
No agent, no firmware update, no configuration change. Works on equipment of any age, from any manufacturer.
Secure cross-organisation sharing
Share specific assets with partners, customers or regulators, with granular rights by user, time and location. No network interconnection required.
Extends legacy equipment lifespan
Remove the risk attached to unpatched legacy OT and equipment can keep running well beyond its intended lifecycle.
Industrial control systems and SCADA
PLCs, RTUs, HMIs and SCADA systems are hidden from internal and external threats alike — regardless of whether the surrounding network is compromised.
Legacy OT equipment
Equipment running 15–30 years with no patch path becomes protected without modification. It operates exactly as before, simply invisible to everyone unauthorised.
Medical devices and clinical IoT
Devices that cannot be patched without regulatory re-validation are protected externally — without touching the device or its validated status.
Energy and critical infrastructure
Substations, generation assets and grid control become invisible to reconnaissance while authorised operations and maintenance access continues.
Supports IEC 62443 zone and conduit requirements (62443-3-2) by making each protected device its own zone with a default-deny conduit. Contributes to NIS2 Article 21 risk analysis (21.2a) and access control (21.2i), and implements the attack surface reduction principles of NIST SP 800-207.
