Hello, I’m Matthew.
Founder of 39D, helping small businesses get IT and cybersecurity right.
I founded 39D, a UK managed service provider supporting small and growing businesses. My work spans managed IT support, Microsoft 365, cybersecurity, backup and business continuity, cloud, connectivity and VoIP, backed by more than 20 years of hands-on technical experience.

MS
Practical technology leadership for growing businesses.
What I focus on
Technology that helps smaller businesses operate securely and grow confidently.
Most businesses do not need technology for technology's sake. They need reliable support, sensible security, clear ownership and someone who can turn technical decisions into business decisions.
Cybersecurity
Practical protection for SMEs including MFA, endpoint security, Microsoft 365 security, backups, staff awareness, Cyber Essentials and business continuity.
Cybersecurity expertise →IT management & direction
Senior technical oversight for organisations that need an outsourced IT manager, virtual IT director or experienced technology partner without building a large internal team.
IT management expertise →39D
The managed service provider I founded.
39D provides managed IT support and cybersecurity services to small and growing UK businesses. I remain closely involved in technical direction, security, resilience and the difficult decisions that sit behind reliable business IT.
Technical depth
MSP leadership backed by ISP and network engineering experience.
My background in BGP, IPv6, routing, high availability, DDoS resilience, MikroTik and ISP infrastructure remains an important part of what I do. It gives 39D and its clients access to technical depth that is unusual in a small-business MSP.
