About Advent IM
Trusted cyber and information security specialists, delivering tailored GRC solutions across the UK’s public and private sectors.
Leading Independent Security Experts, Working With You
At Advent IM, we are one of the UK’s leading independent cyber and information security consultancies. Our expert team specialises in Governance, Risk, and Compliance (GRC), helping organisations across the public and private sectors implement best-practice security policies, procedures, and controls to effectively understand and manage risk.
With a truly holistic approach, we offer consultancy services in Information Security, GRC, Physical Security, Business Continuity, and Data Protection. As a trusted Crown Commercial Services Supplier through the G-Cloud Frameworks and a recognised Cyber Security Supplier to HM Government, we bring deep experience and credibility to every engagement.
Our approach is collaborative, not prescriptive.
We work with you, not at you—providing tailored, vendor-independent advice that aligns with your specific business needs and drivers. We don’t just deliver solutions; we mentor and empower your teams to build sustainable, long-term security practices as your organisation evolves.
At the heart of everything we do is a commitment to building lasting partnerships based on trust, transparency, and integrity.
