The IT-to-OT pipeline is one of the most active sourcing channels in OT security recruitment right now, and it makes sense why. The IT security market is saturated and the roles are competitive, so a lot of experienced IT security professionals are looking at OT and seeing a genuinely interesting alternative.
Moving across requires, above all, a mindset shift. Candidates need to know what skills and knowledge transfer, and how to apply it in more industrial environments.
Why IT Professionals are Making the Switch to OT
When we talk to candidates considering the move, the same three reasons come up again and again:
- It’s a growing industry with more roles becoming prominent, but nowhere near as saturated as traditional IT cybersecurity. This means less competition for good positions.
- The day-to-day is genuinely more varied. OT security roles tend to carry more diverse responsibilities than equivalent IT positions, spanning engineering, compliance, and hands-on site work.
- Job security. Regulatory pressure (NIS2, IEC 62443, NIS CAF) is driving mandatory hiring across critical infrastructure, and that demand isn’t slowing down.
What Transfers Between IT and OT
A background in network security, risk and compliance, or governance tends to translate well since the underlying skills of assessing risk and securing infrastructure carry across. What doesn’t transfer automatically is the operating context (link to OT vs IT blog): the priority on uptime over confidentiality, the physical safety implications of every decision, and the reality of working alongside engineers on a live industrial site rather than purely at a desk.
Some specialisms make the jump more smoothly than others:
- Regulatory, risk, and compliance backgrounds tend to do well – the nature of the industry rewards that discipline.
- Network security experience is genuinely useful and a common entry point.
- SOC (Security Operations Centre) backgrounds can be the hardest fit, since SOC work is built around IT-first incident response patterns that don’t map cleanly onto OT environments.
What Matters More in OT, Qualifications or Experience?
Experience is critical, and it’s often the route to earning the right certifications in the first place. But qualifications carry real weight in this market, particularly with consultancies, who often hire around existing certifications to give clients confidence in who they’re placing on-site. If you can pair OT-specific certifications with a solid cybersecurity background, it can open the door to a more senior role than experience alone would allow.
The Certification Ladder
For most IT professionals making the move, the certification path looks something like this:
- CompTIA Security+
The standard entry-level cybersecurity certification, and the natural starting point for anyone moving from a general IT background into a security specialism, OT included. - CompTIA SecOT+ (launching December 2026)
CompTIA’s first OT-specific certification, currently in beta. It’s brand new, but its existence is itself a signal of how quickly OT security is expanding. - ISA/IEC 62443 Cybersecurity Certificate Program
Not one certificate but a handful (Risk Assessment, Design, Implementation, Maintenance, and more), building into the standards-based pathway most widely recognised across OT employers and consultancies. - SANS GIAC GRID (ICS/SCADA Security) and other SANS ICS courses
Hands-on, technical certifications for candidates specialising further into ICS/SCADA security. - GICSP (Global Industrial Cyber Security Professional) and CISSP
Treated as the gold standard once you’re established in the field, alongside the “Expert” level modules of some of the certifications above for those going deep into a specialism.
Common Mistakes IT Candidates Make in OT Interviews
The most common misstep is talking about security the way you would in an IT interview. A few things to keep in mind:
- Don’t lead with confidentiality, data protection, or rapid isolation as your default response to an incident. Those instincts don’t transfer directly to OT security practices, meaning it can read as a red flag rather than a strength.
- Instead, show that you understand why availability and physical safety come first.
- Acknowledge the mindset shift directly. By naming it, you can show you know why OT prioritises differently, and you’re not just assuming the same playbook applies.
- Share the thinking and rationale behind your decisions, not just the actions you’d take. It’s how you understand systems and processes behind the operations that matters most to an OT interviewer.
How to Frame an IT Background on an OT Application
Don’t downplay the IT experience but frame it as the foundation, not the whole story. Be specific about which parts of your background map onto OT (network segmentation, risk assessment, compliance frameworks) and be upfront about what you’ve done to close the gap, whether that’s a CompTIA Security+ or SecOT+ certification, self-directed learning about industrial protocols, or exposure to engineering environments. Employers hiring from the IT-to-OT pipeline expect the transition story.
Knowing what makes a strong OT security hire – the certifications that matter, the sectors that are hiring, the experience that actually transfers – is not something a generalist recruiter can fake. It requires deep familiarity with the field.
Frequently Asked Questions
Is it hard to move from IT security to OT security?
It’s a genuine mindset shift rather than a simple lateral move, but it’s one of the most active and well-supported career paths in cyber security right now, particularly for candidates with network security or risk and compliance backgrounds
What certifications help with an IT to OT security transition?
GICSP and the ISA/IEC 62443 Cybersecurity Certificate Program are the two most widely recognised. Pairing either with existing IT security experience is a strong combination, particularly for consultancy roles.
Do I need engineering experience to work in OT security?
Not necessarily, but hands-on familiarity with physical or industrial systems is an advantage. Many OT security professionals do come from engineering or controls backgrounds rather than a purely IT route.
Which IT security specialism transitions most easily into OT?
Regulatory, risk, and compliance backgrounds tend to transition smoothly, as does network security experience. SOC-focused backgrounds can find the shift harder, since SOC playbooks are built around IT-first incident response.
