Cloud Security. Simplified.

We secure your Azure and Microsoft 365 tenants with the the highest cloud security benchmarks and best practices so you can focus on your driving your organisation forward.

What we do

We help organisations find and fix security weaknesses across Microsoft cloud environments.

Cirrus Security provides practical security assessments and remediation for Microsoft 365 and Azure. We identify configuration weaknesses, excessive access, identity risks and security control gaps, then turn those findings into clear, prioritised actions your organisation can actually implement.

From securing Entra ID and Microsoft 365 to reviewing Azure workloads and helping remediate cloud security findings, our focus is simple: reduce risk, strengthen your security posture, and make Microsoft cloud security easier to manage.

About Me

Hi, I’m Patty, founder of Cirrus Security. I’m a cloud engineer specialising in Microsoft cloud security, with hands-on experience working across Azure infrastructure, identity, security controls, automation and cloud operations.My focus is helping organisations understand where their Microsoft cloud environments are exposed and what to do about it. Through Cirrus Security, I provide Microsoft 365 and Azure security assessments, identity and access security, and practical remediation guidance designed to turn security findings into clear, actionable improvements. My approach is straightforward: security should be technically sound, proportionate to the organisation, and practical to implement. I focus on reducing risk without introducing unnecessary complexity or cost.
