Operational Technology Security
Your OT environment doesn’t run like a standard office network, so it shouldn’t be secured like one. We protect the industrial control systems, SCADA platforms and physical processes that keep your operation running.
OT security protects the systems that control physical processes and industrial machinery — not just the data on a server. Unlike a standard IT breach, an OT incident can mean safety hazards and real operational disruption, which is why it needs security designed specifically around industrial environments, not IT security applied as an afterthought.
Continuous surveillance of routers, switches, servers, applications and endpoints, so anomalies and potential issues are caught early, not after the fact.
Real-time insights into system health, with log management built around OT environments rather than adapted from a generic IT tool.
A hardened backup solution for disk imaging and file-level backup, with no third parties touching your interface or backend protocols.
Removable media is one of the most common ways threats reach isolated OT systems. We help control and monitor it at the point of entry.
A secure remote access platform, typically implemented within a day and without disrupting operations, so engineers and vendors can connect safely from anywhere.
Risk assessments aligned to the IEC 62443 standard for industrial control systems, measured against the right benchmark, not a generic IT one.
Thorough assessments of ICS, SCADA systems and embedded devices, simulating real-world adversary tactics across your entire OT attack surface.
Why It's Different
A vulnerability scan or a misconfigured firewall on a standard IT network is a headache. The same gap in an OT environment can stop a production line, take down critical infrastructure, or create a genuine safety risk. That's why OT security has to work around your operational constraints, not the other way round — assessed, implemented and tested without putting live processes at risk.
Discuss Your OT Environment
A structured approach built around industrial environments, not a generic IT rollout.
We map your operational technology estate — ICS, SCADA and the IT/OT boundary — to understand what's actually at risk.
We assess your environment against the IEC 62443 standard, identifying gaps between current controls and what industrial systems require.
Monitoring, secure remote access, backup and media hygiene controls are deployed around your operational systems, without disrupting production.
Continuous log management and network visibility, backed by periodic ICS penetration testing, to keep pace with new threats.

Risk assessments benchmarked to the industrial security standard
Glen and the team have a fantastic understanding of both IT and OT. Having Sophlee in our corner ensures we have the best support and engineering best practice at our fingertips.
OT environments control physical processes and machinery, not just data. A breach can mean safety hazards and operational disruption, not just a data loss incident — so OT security has to account for uptime, safety and legacy equipment in a way generic IT security doesn't.
Yes. Our IEC 62443 risk assessments benchmark your industrial control systems and OT infrastructure against the standard's requirements, identifying gaps in your current controls.
We design implementation around your operational constraints. Some controls, like secure remote access, can typically be deployed within a day without disrupting operations — and assessment work is planned around your production schedule, not the other way round.
Our ICS penetration testing is scoped and conducted carefully around your operational environment, simulating real-world adversary techniques across ICS, SCADA and embedded devices without putting live processes at risk.
Yes. Since 2008 we've worked across critical infrastructure, defence, education, government and commercial sectors, and our accredited team is trusted by MoD, NATO and Police sector bodies.
It sits alongside it. Most organisations with an OT environment still run standard IT alongside it — see our Cyber-Focused IT Support & Infrastructure page for how the two fit together.
Pair ICS penetration testing with continuous monitoring, or explore our wider penetration testing capability across IT and OT.
