Mathew Ettelaie, KPMG

Experienced Leader Award

MCA Awards 2026 Finalist

Mathew Ettelaie is a trusted adviser in environments where cyber security meets national resilience, public safety and critical public services.

Mathew is a Director in KPMG’s Cyber Defence Services practice and a nationally recognised leader in security testing and ethical hacking. Having progressed from hands-on technical delivery to leading KPMG’s UK Security Testing and Ethical Hacking team, he oversees a multidisciplinary group of over 60 specialists delivering high-risk cyber assurance engagements across defence, government, critical national infrastructure and regulated industries.

He has supported organisations including the Ministry of Defence, Home Office, Ministry of Justice, NHS and major corporates such as BAE Systems, Lloyds Banking Group and Vodafone, often in situations where systems must remain operational during testing.

Mathew is recognised for combining deep technical credibility with sound judgement and ethical leadership. He has advised senior leaders on nationally significant programmes, contributed to regulatory assurance frameworks such as CBEST, TBEST, GBEST and TIBER, and is known for his refusal to offer false assurance, instead helping boards and regulators understand real-world risk and resilience.

His leadership is most visible during moments of crisis – supporting clients to rebuild during major cyber incidents, including ransomware attacks on critical public services, with calm, decisive leadership under intense pressure.

Mathew has played a significant role in shaping the wider cyber security profession through industry bodies, government advisory groups, international engagements and academic outreach. His focus on stewardship – developing people, strengthening organisations and raising professional standards further adds to his reputation as an outstanding leader.
