See your real Microsoft 365 security posture... before an attacker does
Businesses rely on Microsoft 365 for identity, collaboration and daily operations, which makes it one of the biggest targets for cyberattacks. Security Doctor is a specialist‑led assessment that gives you a complete, evidence‑based picture of your security posture across identity, devices, data and configuration.
It combines automated tenant analysis with expert interpretation to uncover hidden risks, configuration weaknesses, governance gaps and unnecessary costs, all mapped against Microsoft best practice and benchmarking.
Whether your priority is reducing risk, improving compliance or optimising licences, Security Doctor provides clarity, confidence and a practical roadmap for strengthening your businesses defences.

Challenges we solve
Microsoft 365 is a powerful security platform, but only when configured correctly. Over time, rapid deployments, changing requirements and organic growth create blind spots, leaving businesses unknowingly exposed.
Threat actors increasingly exploit misconfiguration rather than malware. Old accounts, unprotected devices, weak identity policies, or misaligned settings can silently open the door to compromise.
Key challenges
- Configuration drift leading to gaps attackers exploit
- Lack of visibility into identity, device and data‑level risk
- Under‑utilised tools and paying for licences you don’t need
- Limited internal resource to review complex M365 security settings
- Difficulty demonstrating compliance with industry benchmarks
What's included?
Security Doctor is a structured, automated and expert‑led review of your entire Microsoft 365 security posture, with a focus on the areas that matter most: identity, devices, data, compliance and licensing.
