I help UK, EU and US businesses harden Microsoft 365 and cloud environments against real-world threats, and architect the Azure/AWS infrastructure underneath it — backed by 18 completed projects, 5,200+ hours and a 100% Job Success score. What I do: - Microsoft 365 & cloud security — Intune/Entra ID, conditional access, attack surface reduction rules, device compliance, zero-trust hardening - Cloud architecture — Azure/AWS environments designed for security and resilience, not just cost - Network & infrastructure — Meraki, VPN/firewall, Active Directory, Hyper-V, Teams Phone/VoIP - Ongoing protection — monitoring, patching, incident response, and documentation that holds up to an audit I'm fully insured ($3M public liability) and typically respond within hours. If something in your M365 tenant or cloud setup doesn't look right — or you just want a second pair of eyes before it becomes a problem — that's exactly the kind of call I want. Tell me what's going on and I'll tell you exactly how I'd approach it.
