YOU HANDLE THE STRATEGY.We handle the risk.
QMC4 Cyber is a managed security partner for ambitious UK businesses. We pair a 24/7 security operation with an AI-agent layer that does the work humans shouldn't have to — round the clock, every day.
Security that earns its place
at the board table.
Most cyber attacks no longer announce themselves. They drift in through a phished mailbox, a dormant identity or a misconfigured cloud rule, and surface weeks later as a regulator's letter or a client's phone call.
By then, the cost is no longer technical — it's reputational, contractual and financial.
QMC4 Cyber is built around that reality. We run a 24/7 security operation backed by an AI-agent layer that does the relentless work humans shouldn't — triage, correlation across thousands of signals, and immediate first-response on the patterns we recognise.
Our vCISO team translates what we see into language your board, your insurer and your auditor recognise.
We handle the risk.
Four pillars.
One accountable team.
A fully-staffed security operation, on call every hour of the year. Our AI agents triage and correlate alerts the moment they land, so by the time a human engineer is involved, the noise has been stripped out and what's left is worth their attention.
We watch how every identity in your business actually behaves — the systems they touch, the hours they keep, the patterns they fit — and we flag the ones that drift. When something doesn't look right, our zero-trust controls stop lateral movement before it becomes an incident.
We sit alongside your leadership team and do the work a CISO would do — Cyber Essentials, Cyber Essentials Plus, ISO 27001 alignment, security questionnaires, and a quarterly board paper they can actually use.
Laptops, identities, cloud, helpdesk — managed by the same team responsible for your security. No handoffs between separate suppliers, no finger-pointing when something breaks, and no gap between the people who fix the problem and the people whose job it was to prevent it.
An AI engineering team,
applied to cyber.
Most cyber security companies have added AI to what they were already doing. We came at it from the other direction.
QMC4 has spent years designing and shipping agentic AI systems for regulated industries — work where the system has to be explainable, auditable and operationally trusted, because real businesses depend on it.
QMC4 Cyber is what happens when that engineering discipline meets a managed security operation. The result is a service that pairs experienced security engineers with an AI-agent layer that does what software should: handle the relentless, repeatable work, so people can spend their time on the parts that need judgement.
We'd rather be the team your CFO quietly trusts.
Verifiable. Accountable.
Plain-speaking.
Most of our first conversations take 30 minutes. No sales theatre, no fear-based pitching — just a clear read on where your business actually stands and what would move the needle.
