Security, built for the way threats actually move.
Most breaches now unfold in hours, not quarters. Annual penetration tests and alert-only monitoring can’t keep up. We give UK mid-market organisations a continuous, outcome-led security operation — built on Microsoft Sentinel, delivered by a UK-based SOC, and governed to a standard your board, your insurer and your auditors all recognise.

01 The gap
The distance between annual security and real-world attacks.
Breach timelines are measured in minutes, not days. Cyber insurers now want evidence of continuous monitoring — not a penetration-test certificate from nine months ago. And boards are asking harder questions: how quickly would we know? Who is watching at 2am? Can we prove we responded fast enough? For most mid-market organisations the honest answers are uncomfortable — not because the tools are missing, but because there aren’t enough people, hours or processes to run them at the level now required.
02 The framework
The 3Gi Continuous Security Framework.
Four pillars wrapped in a continuous review cycle. Every service we deliver sits inside one of them, and every engagement moves through them in order. It maps cleanly to NIST CSF and ISO 27001 — so your risk and procurement teams can validate it without objection.
Pillar 01
Assess
Baseline your current exposure and benchmark against your industry. Where are we exposed today, and how do we compare?
Explore Assess →Pillar 02
Protect
Enforce the baseline controls that stop the routine attacks before they land — identity, endpoint, email, SaaS and people.
Explore Protect →Pillar 03
Operate
24/7 detection, investigation and response, with evidence you can show the board. Who is watching at 2am?
Explore Operate →Pillar 04
Govern
Turn your security posture into continuous, audit-ready proof — for your board, your insurer and your regulator.
Explore Govern →↻ Evolve
The cycle that keeps the other four honest. Quarterly service reviews, threat intelligence, cyber AI and roadmap development keep your posture moving with the threat — measurable year-on-year improvement, not service stagnation.
03 Why 3Gi
We built the operation we’d want running our own estate.
Fifteen years as a governance-led, Microsoft-first managed service provider taught us where security is won and lost. It is rarely the strength of the tool. It is whether someone owns the outcome, and whether the whole thing is governed well enough to prove it worked.
A
Outcome-led, not alert-led
We own triage, investigation and response. Automated playbooks and SOAR close the routine events — today around 70%, heading toward 90% — so analysts spend time on what needs judgement. You only see incidents that matter.

B
Built on Microsoft Sentinel
One platform across cloud, identity, endpoint and SaaS — built inside your own Azure tenant, owned by you. Bespoke connectors, KQL threat hunting, version-controlled detection. 12 releases since last January; on v2.2.

C
Governed from day one
Quarterly reviews, SIEM audits, documented runbooks and board reporting are part of the service. Crucially, the team that audits the SOC is not the team that runs it — no one marks their own homework.

D
A partner, not a faceless MSSP
An integrated team who learn your business. 90-day rolling contracts, open-book pricing, no lock-in — everything stays in your tenant. We earn the next quarter by improving, not by trapping you.

The security-led difference
We don’t just consume security tools — we build them. Our own ISV, RoboShadow, runs across more than 1.5 million endpoints, is SOC 2 certified, and came through the NCSC / GCHQ startup programme. It does vulnerability management, external attack-surface scanning and AI penetration testing, and fills the gaps the Microsoft stack still leaves — backed by a 40-strong development team.

How we built 24/7 SecOps for Morgan Hunt.
Morgan Hunt is a UK recruitment agency operating across London, Birmingham, Manchester and Glasgow. We moved them from fragmented internal monitoring to a 24/7 Microsoft Sentinel operation with outcome-led response and quarterly governance reviews.
A real integrated team who understand our business, technology and processes. Each quarterly update includes a review of the roadmap and how the offering is expanding. Sam Porter — IT Director, Morgan Hunt Read the case study →
Live engagement · Czarnikow
For Czarnikow — a global agri-commodities business with operations spanning the UK, China, India, Australia and the US — we run a live proof of concept delivering the full SecOps service with Microsoft Sentinel plumbed into their own tenant. The model is exactly what we propose at scale: follow-the-sun 24/7 coverage, a daily operations report, a living risk profile, and a board pack the leadership team can read in two slides or fifteen.
05 The operating model
One operation, three teams, no ambiguity.
The technology is the easy part. The hard part — and the part that decides whether security is done well — is the humans who interact with it. Our service design maps a clear RACI between your in-house IT, your existing MSP and our SOC, then tabletop-tests it before an incident ever happens.
Detect
Sentinel → PSA, live
Every Sentinel alert raises a ticket the instant it fires and follows a Jira Ops escalation path. P1s start escalating immediately — nothing sits in a queue waiting for morning.
Respond
Contain before you wake
Low-level automations block malicious IPs and, on a confirmed breach, revoke sessions and secure the account — at 3am, before an analyst is even involved — then investigate.
Govern
A cadence you can set your watch by
Weekly operational reviews, monthly performance (MTTR, SLAs, false-positive reduction) and a quarterly board pack — underpinned by a vCISO framework, not a single named individual.
