18 months. Three consultants. One binder of policies.

Then the auditor arrived. They didn't want your intentions. They wanted evidence — proof that those policies were deployed, configured, and operational inside your Microsoft 365 tenant. You had nothing.

That's exactly what we replace. We don't write policies and leave. We engineer your security and prove it's working — every single day.

From vulnerability reports to unbreakable security

Generic Governance, Risk & Compliance (GRC) platforms connect via read-only APIs. They can tell you what's broken — but they can't fix it. We deploy, configure, enforce, and prove.

Generic GRC Platforms
Global Micro
API Access
× Read-only (Directory.Read.All, Policy.Read.All)
Read/write tenant orchestration — we deploy configurations directly
Vulnerability Data
× 15-day retention limit, 1,000-item daily cap
Unlimited native retention via Defender and Log Analytics
Remediation
× Passive alerting — generates tickets for your IT team
Active deployment — identity, endpoint, data, cloud security, and compliance controls
Configuration
× Checks against a basic checklist
Governs deep Intune settings, CIS benchmarks, and Zero Trust capabilities
Objective
× Produce documentation to pass an external audit
Engineer an environment that is architecturally resilient

Other platforms identify vulnerabilities. We eliminate them, then prove they stay eliminated.

The business case your board needs.

£180-250k Annual cost avoided

Replace a Security Architect, Compliance Analyst, and Endpoint Engineer with one operational partner — at a fraction of the cost.

68% RFPs require ISO 27001

No certificate means no shortlist. We get you audit-ready so you qualify for the contracts that matter.

8 weeks To audit-ready

Industry average is 12-18 months. Our operational approach deploys security and starts evidence collection from day one.

NIS2 Art. 20 Personal director liability

Directors face personal accountability for security failures. We provide daily evidence of due diligence.

Managed Security Operations

Your security team. Without the headcount.

Hiring a full-time security architect, a compliance analyst, and an endpoint engineer costs more than most mid-market businesses can justify. We provide the same depth — deployed, operated, and proven — as a managed service.

One team. Every layer. From identity and endpoint through to servers, cloud, and network perimeter. The same engineers who deploy your security also manage your compliance and prepare for audit.

We don't monitor your compliance.
We engineer your security.

1,200 Microsoft tenants secured across EMEA. Here's what 30 years teaches you.

Security engineers, not just advisors

We operate the systems we secure. Every policy references your actual configuration because we configured it. When the auditor checks, it matches.

Evidence, not paperwork

Automated collection from your tenant. Auditors see real configuration data — not self-assessments written after the fact. Updated daily.

Certification in weeks, not months

The industry takes 12-18 months because they're manual. We take 8 weeks to deploy, and your evidence trail starts building from day one.

Measurable risk reduction. Not aspirational targets.

Our 105-risk register maps every threat to specific controls. Here's what happens when those controls are deployed and evidenced.
