See: Gain granular visibility into risky users, feature enablement, secure scores, and compliance posture across your M365 estate.

You’re Paying Twice for Security — Here’s Why

Most organisations don’t lack security tools, they lack visibility.

It explores how complexity weakens security, why “best‑of‑breed” often backfires, and why visibility is now the key to stronger, simpler protection.

If you run Microsoft 365, this article may change how you think about security.

No Offshore Components: All service components are hosted within the UK, with no offshore processing.

Governance & Monitoring

Security Assessments: Annual penetration testing and automated health checks via Azure Application Insights ensure continuous monitoring and resilience.
Incident Response: Any customer-impacting security incident is reported within one hour of discovery, supporting rapid containment and transparency.
Identity & Authentication: Multi-factor authentication (MFA) is enforced across service interfaces, limiting access to verified users only.
