Bryan Littlefair is the Founder and CEO of Cambridge Cyber Advisers (CCA), a consultancy built on the principle that cyber security advice should come from those who’ve lived the responsibility — not just studied it. With over 25 years’ experience leading security functions for some of the world’s largest organisations, Bryan is a trusted advisor to boards, executive teams, and the global CISO community.

Before founding CCA, Bryan held global CISO roles at Vodafone Group and Aviva, where he led transformational security programmes across complex, international environments. At Vodafone, he built and embedded the company’s global security strategy from the ground up. At Aviva, he drove a large-scale shift in cyber capability to support the business’s digital evolution.

Bryan’s experience extends beyond corporate roles. He previously led the Security Research Lab at British Telecom, contributing to major global, EU, and academic research initiatives. Today, he continues to work at the cutting edge — advising private equity firms, venture capital funds, and start-ups on securing portfolios and shaping future-ready security products.

A regular keynote speaker and holder of multiple patents in cyber security, Bryan is also a passionate mentor and thought leader. Under his leadership, CCA combines hands-on experience, sector-wide insight, and government partnerships to deliver impactful, threat-led security strategies to organisations of every size.
