A security operation that doesn't sleep, run by people who do.
Sentinel is the spine of QMC4 Cyber. A 24/7 security operation that watches your environment every hour of the year, with an AI-agent layer that strips the noise out of thousands of alerts before any human sees them — so engineers spend their time on what's actually worth their attention.

What's included
Inside Sentinel,
in plain English.
AI-agent triage and correlation
Every alert is triaged and correlated by our AI-agent layer the moment it lands. Human engineers see signal, not noise — and the audit trail explains why.
Telemetry collection
Endpoint, identity and cloud telemetry collected from the platforms you already run — Microsoft 365, Google Workspace, Entra ID, Okta, AWS, Azure, common EDR vendors.
Incident response runbooks
Runbooks tailored to your environment, your contractual obligations and your regulatory reporting timelines. Tested through quarterly tabletop exercises.
Named human escalation
When an alert turns into an incident, you reach a named senior engineer who knows your environment — not a tier-one queue.
Monthly briefings, quarterly tabletops
A monthly briefing for your IT lead in plain English, and a quarterly tabletop with the leadership team to test the runbooks before you need them.
How it works
Four phases.
One accountable team.
Onboard
Connect telemetry sources, set behavioural baselines, define escalation paths. Typically two weeks from signed SOW to full coverage.
Operate
24/7 monitoring with AI-first triage. Only the alerts worth a human eye reach a human, and we tune continuously.
Respond
Confirmed incidents trigger your runbook. Named engineer leads the response, your stakeholders are kept informed, regulatory clocks are managed.
Review
Monthly briefing, quarterly tabletop, continuous tuning. The service gets sharper the longer you run it.
Why Sentinel
Three reasons
this is different.
AI-first, not AI-second
Most MDR providers bolted AI onto a tier-one queue. We came at it from the other direction — agentic AI is what triages first, and engineers handle what genuinely needs judgement.
One accountable team
No SOC handoff drama. The team running detection is the team you contracted — not a sub-supplier you can't reach when something breaks.
Built for UK & Channel Islands
NCSC and ICO timelines are the default, not an afterthought. Your runbooks reference the regulators you actually answer to.
Sentinel — FAQ
Buyers usually
ask these next.
What gets monitored?
By default: endpoint telemetry from your EDR, identity events from your IdP (Entra ID, Okta or Google Workspace), cloud audit logs from your SaaS estate, and any custom log sources you bring. We tune the scope during onboarding so you only pay for what you need.
What happens when an alert fires at 3am?
If it's noise, our AI agents close it with a documented reason and you never hear about it. If it's signal, a human engineer is engaged within minutes, the runbook starts, and the named contact in your business is called.
Does Sentinel work with our existing security tools?
Yes. Sentinel sits on top of the EDR, IdP and cloud platforms you already run. We do not require a rip-and-replace, and we will tell you honestly if the tool you have today is adequate for the threat model you actually face.
How does Sentinel pair with the other services?
Sentinel is most powerful when paired with Identity (so we can correlate endpoint and identity events) and Counsel (so the regulatory side of an incident is handled by the same team). It works as a standalone service too.
