Brief Overview

Who are we?

Our Approach

Advent IM is one of the UK’s leading independent cyber security specialist, with a unique approach to providing holistic security management solutions.

We work with clients nationwide across both the public and private sectors to implement best practice security policies, processes and procedures and understand security threats in order to address security risk.

Advent IM is a Crown Commercial Services Supplier through the G-Cloud Frameworks as well as a supplier to HM Government.

We pride ourselves on putting our clients first and believe in delivering consultancy in partnership with you not delivering consultancy ‘at’ you. Our collaborative approach is both consultative and facilitative and each solution is bespoke to your business needs and drivers.  We mentor you through the processes so that you can continue to maintain effective security practices as your business changes.

We believe in building long term partnerships with clients based on trust by working in an open and ethical way. In addition, our advice is completely vendor independent and unbiased.

Our Team

Advent IM began in 2002 as a small consultancy operating out of a single office in the heart of the Midlands. Over the years we have successfully grown the company organically and today have a highly specialist team of delivery and support staff based in purpose built office premises, with training and conference facilities in the Midlands and London.

Over the years we have developed sound business practices which have resulted in consistently high levels of client satisfaction. We are also committed to continuous improvement through our ISO 9001 and ISO 27001 accreditations as we continue to grow.

Our Consultants are recognised experts in their field and have extensive experience in delivering security solutions. They include CESG Certified Professionals (CCP), ISO 27001 Lead Auditors, ISO 22301 Lead Auditors, PRINCE2 Practitioners, Home Office trained physical security assessors.

Our Consultants are also members of the Institute of Information Security Professionals (IISP), British Computer Society (BCS) and The Security Institute (SyI). In addition our Managing Director, Mike Gillespie, is the Director for Cyber Strategy and Research for the SyI.
