OT & ICS Penetration Testing
Control-network testing that treats safety and uptime as first-order constraints — the IT/OT boundary, tested without putting operations at risk.
What it covers
Operational technology was built for reliability, not to face the internet, yet business systems and remote access have connected it anyway. The consequence of compromise is not lost data but a stopped process or a safety event, so OT testing is a different discipline: we work from the enterprise inward, focus on the boundary and the paths across it, and treat live systems as things to be understood, not disrupted. Testing aligns to IEC 62443 and NIST SP 800-82.
What we test
Every engagement is scoped to your environment, but these are the areas a OT & ICS test engagement covers.
IT/OT boundary
The segmentation and conduits between corporate IT and the control network, and whether they hold.
Remote access
Vendor and engineer access paths into control systems — a frequent and high-value entry point.
Enterprise-to-OT paths
How an attacker moves from a phished office workstation toward systems that control the process.
Exposure discovery
Passive and careful identification of exposed control systems, historians and HMIs.
Safe methodology
Testing scoped and paced so that live operations and safety systems are never put at risk.
How the engagement runs
The same defensible sequence every time.
Scoping and a fixed-price quote, reconnaissance and threat modeling, manual exploitation with same-day escalation of critical findings, a report your engineers and auditors can both use, and a free retest once fixes ship.
OT & ICS test, answered
Will testing disrupt our operations?
No. OT engagements are deliberately conservative — much of the work is passive, active testing is agreed system-by-system, and anything that could affect a live process is excluded or performed only in a maintenance window.
Do you test the enterprise side too?
Yes, and usually first, because the realistic path to OT runs through corporate IT. We follow that path to the boundary rather than starting inside the control network.
