William Rimington

William is the co-lead of the Thomas Murray Cyber Risk practice and is based in the London office.  Over the course of a 25-year career in technology, risk and cyber security, William has worked tirelessly on the science and art of technical security testing.  He helps organisations prepare for the reality of modern security incidents and the critical role that developing, implementing and validating security defences plays in standing up to the constantly evolving world of cyber-attacks.

Between 2018 and the end of 2022, William was instrumental in building and then co-leading the EMEA cyber security practice for a global risk consultancy specialising in cyber, business intelligence and investigations.

He takes specific responsibility for technical testing and cyber security governance, risk and control services as well as driving strategic solutions for his clients.  This includes cyber due diligence in the deal space and on-going monitoring of cyber risk across investment portfolios both in large corporates and private equity.

He led the Global Centre of Excellence for Ethical Hacking at PwC and led cyber security assurance reviews in their UK practice.  William drove the development of the data assurance practice in the PwC London office supporting assurance work and advised on technology risk more broadly. 

He is adept at communicating current cyber security issues and themes with client executive boards, audit committees, and at external speaking events. With a background in software development and data analytics, his achievements and experiences are valued by his clients and his innovation has, for example, taken manual assurance playbooks into highly efficient digital solutions to test security operation centres.
