What is TLPT?

Definition of TLPT

TLPT (Threat-Led Penetration Testing, threat-led penetration testing) is an advanced form of security testing in which attack scenarios are built on the basis of real threat intelligence for a given organization and sector. TLPT simulates the actions of a real, determined attacker on production systems.

TLPT and DORA

TLPT is a requirement of the DORA regulation for significant entities in the financial sector. Key characteristics:

• testing based on real threat scenarios,
• carried out by independent, certified testers,
• on critical functions and systems in a production environment,
• at a frequency of at least once every three years,
• in line with the European TIBER-EU framework.

How does TLPT differ from a classic pentest?

• Scope — critical business functions, not a single application.
• Realism — scenarios from threat intelligence, on live systems.
• Independence — a requirement for external, certified providers.
• Legal basis — a regulatory obligation, not just good practice.

How to prepare for TLPT?

1. Identify the critical functions and the systems that support them.
2. Ensure the maturity of monitoring (SOC), so that testing can be safely conducted in production.
3. Plan the test with an independent provider in line with TIBER-EU.
4. Turn the results into remediation actions and validate them.

TLPT raises the bar from “does the application have vulnerabilities” to “can the organization withstand a real, targeted attack” — and for the financial sector it is an obligation.
