Microsoft 365 Security & Managed Services

Microsoft 365 is a foundation, not a security strategy.

Most SMBs think a Microsoft 365 license means they're secure. It doesn't. You need device management, endpoint security, patch controls, and proper admin governance. An auditor, insurer, or Cyber Essentials assessor will look right past your M365 license and ask: can you actually manage and protect your systems?

I help organisations handle sensitive data — patient records, client information, financial data — get their security right. No jargon. No overselling. Just a practical assessment of where you stand and what needs to change.

The Problem

Microsoft 365 alone leaves gaps

An email license doesn't cover device management, threat detection, or email security. Here's what "complete" actually looks like.
