Hi, I'm Marcus Gwilliam.

Welcome to MG IT Security Ltd. Providing IT Security across the UK.

For the past 15 years I've worked in various IT Security roles, including for some of the largest UK based regulated financial service companies. I have a proven track record of delivering UKAS accredited ISO27001 and PCI-DSS v4 compliance, as well as CSA Star and Cyber Essentials Plus certifications.

On this website you can learn more about how I can improve your companies IT Security posture against real world threats and provide expertise to achieve different security accreditations that would help win new business.
I work with companies throughout the UK both remotely via Microsoft Teams / Zoom / Google Meet etc, and also in person.

If you're interested in working with me then I would be pleased to hear from you. There are three key services I provide:

  • Firstly, I provide IT Security Consultancy Services to SME companies looking to improve their IT Security posture.

  • Secondly, I conduct risk assessments for companies to fully understand and mitigate any potential risks that a new project might introduce.

  • Finally, I'm able to work with your company to help deliver security accreditations and compliance including UKAS accredited ISO27001, PCI-DSS v4, CSA Star and NCSC Cyber Essentials or Cyber Essentials Plus.
