IT security protects data. OT security protects the physical processes that keep power grids running, water safe to drink, and production lines moving.
Knowing the difference is vital if you want to hire the right candidate for the role.
Getting it wrong isn’t only costly, it’s also risky. A severe lack of critical infrastructure can lead to reputational harm, regulatory fines or even complete shutdowns.
With over 20 years’ experience in the industry, we understand how the certifications, skills, experience and priorities stack up between the two disciplines. That plus our network of OT-qualified candidates to draw on is how we deliver specialist hiring support to the UK’s critical infrastructure.

Roles filled
We place OT security specialists across both permanent and contract roles.
Job titles for these roles vary a lot between organisations. We work from the brief, not the title; if your role doesn't fit neatly into a category, get in touch anyway.
We start by understanding your business priorities, and how the brief is supposed to deliver on that. For OT security roles, we map your requirements to certifications, hands-on experience with physical assets, and the specific technical background the position needs.
Once a brief is finalised, we move quickly. OT security hiring depends on candidate availability in a genuinely small market, but our deep network means we are never starting from zero.
There’s also no handoff to a junior consultant who's never spoken to an OT engineer; Ben and Charlie approach candidates directly to send you a shortlist for review and arrange interviews. Because the market is niche, sometimes there are only one or two genuinely qualified people for a role; where a longer shortlist makes sense, we’ll build one.
While the search is live, we stay close to each candidate's position in the market, including counter offers or competing opportunities. When there’s an offer on the table, we mediate the negotiations for the benefit of both employers and candidate through to acceptance and confirmed start date.
Our job doesn't stop once someone accepts. We stay in touch through their notice period and the first few months in the role, checking that onboarding is going smoothly for both parties.
For one global MSSP with multiple roles to fill every month, we work to a cap of three candidates per role to keep the process fast without sacrificing fit.
An OT security recruitment agency sources and vets candidates for roles that protect operational technology - the systems that run manufacturing lines, power grids, and other critical infrastructure. Paradigm Tech specialises exclusively in this niche, across permanent and contract roles.
OT security roles need certifications like IEC 62443 and GICSP, plus hands-on experience with physical, industrial assets - not just IT systems. A recruiter who doesn't understand that distinction will waste time and put forward the wrong candidates.
Yes. We work both permanent and contract OT security hires, often for the same clients and the same decision-makers.
We recruit across consultancies and MSPs, cyber security vendors, government and public sector, critical national infrastructure, manufacturing and production, and SaaS/PaaS.
It depends on the role and how niche the requirement is - OT security is a small, specialised market. Once a brief is finalised, our aim is to move quickly and bring you a shortlist of genuinely qualified candidates rather than a long list of maybes.
