Provable Cyber Resilience is an independent cybersecurity research platform created by UK cybersecurity expert David Whitelegg, focused on measurable assurance, control effectiveness, and operational cyber resilience.
Cybersecurity reporting has never been more sophisticated. Dashboards are richer, maturity models are more detailed, and compliance frameworks continue to expand. Yet major breaches persist.
The problem is not visibility. It is proof.
Many organisations measure what is declared rather than what is independently tested. Controls are assumed to be effective because policies exist, tools are deployed, or metrics appear stable. Real resilience, however, is only demonstrated under operational stress.
This platform focuses on a different question:
Do these controls actually work when it matters?
It shows how cybersecurity assurance moves beyond reported posture to measurable, defensible performance across real services, supporting systems, and critical dependencies.

The AI Labs tools bring these ideas into practice, allowing you to test, simulate, and measure cybersecurity performance under realistic conditions.
Rather than relying on assumed control effectiveness, these tools show how controls behave, where assurance breaks down, and how risk propagates across services, dependencies, and critical operations.
