Threat-Led Penetration Testing (TLPT)
Threat-Led Penetration Testing (TLPT) is intelligence-driven adversarial testing that mimics real threat actor behavior against critical or important functions, required under DORA on a defined cadence for larger financial entities.
How TLPT Differs from Traditional Penetration Testing
Traditional penetration testing evaluates specific systems against known attack techniques. TLPT is broader and more adversarial. It uses tailored threat intelligence to simulate a specific credible threat actor and tests the full response capability, not just the technical controls of an isolated system.
TLPT typically runs across live production environments with limited internal awareness, so it exercises detection and response capability in realistic conditions rather than against pre-notified defenders.
TLPT Under DORA
DORA requires TLPT for financial entities meeting specific size and criticality thresholds. Testing follows the TIBER-EU framework (Threat Intelligence-Based Ethical Red Teaming) or an equivalent, with specific requirements around scope, methodology, provider qualifications, and regulatory notification.
The cadence is at least every three years, though more frequent testing may be required based on the entity's risk profile. See DORA.
TLPT and Program Maturity
TLPT provides some of the most rigorous evidence available on real-world program effectiveness. Organizations that can withstand TLPT-level adversarial testing typically demonstrate substantially different maturity than those that cannot, particularly in detection speed and response coordination under pressure.
