David Clark

CISO
I'm committed to ensuring our clients are well-equipped to handle complex cybersecurity threats. With over 25 years’ experience, I focus on building resilience and promoting a cyber security-first culture that safeguards organisational integrity and supports sustainable growth.

Get to know David

Over the past 25 years I’ve been shaping industry best practice across finance, government and beyond. I pioneered the first GCHQ/APMG-certified Data Breach Course and co-authored an ICO-approved GDPR certification scheme, demonstrating a deep commitment to advancing cybersecurity knowledge and practices.

My strategic efforts at companies like BT and Radianz/Reuters focused on implementing ISO 27001, optimising operational risk and enhancing ROI. As a thought leader in risk management and compliance, I’ve also been recognised as a leading influencer by Thompson Reuters and a global security expert by Kingston Technology.

At QuoStar, I provide advanced cybersecurity solutions and expertise against the backdrop of a rapidly changing threat environment – drawing on my experience as ISO 27001 Lead Auditor and Fellow of the British Computer Society.
