What Is Red Teaming?

Red Teaming (also: Red Team Assessment or Adversary Simulation) is the most realistic form of offensive security testing. Unlike traditional penetration tests, Red Teaming simulates multi-stage, real-world attacks on an organization - spanning technical, physical, and social attack vectors.

A Red Teaming Assessment tests the entire defense chain under real-world conditions: from the initial access phase through lateral movement to achieving critical business objectives. The Blue Team's (SOC, CERT, IT Security) detection and response capabilities are also evaluated.

Red Teaming vs. Penetration Testing

Both approaches are complementary and ideally combine in a comprehensive security strategy.

Frequently asked questions about red teaming companies

What is the difference between red teaming and penetration testing?

A pentest finds vulnerabilities within a defined scope and completes within days to weeks. Red teaming simulates a real attacker against the entire organization over weeks to months - covert, multi-stage and including a test of the blue team's detection and response capabilities.

What is adversary simulation?

Adversary simulation is the methodology at the core of red teaming: emulating the tactics, techniques and procedures (TTPs) of real threat actors against an organization to test prevention, detection and response under realistic conditions.

How do I choose a red teaming company in Europe?

Look for a dedicated red team rather than generalists, verifiable certifications (OSCP, OSEP, CRTO), experience with TIBER-EU and DORA engagements, references, and clearly defined rules of engagement. A reputable provider explains methodology and process transparently in an initial call.

What does a red teaming assessment cost?

Red teaming assessments run for several weeks to months, so budgets depend on scope and objectives. Full regulatory TIBER/DORA TLPT cycles including threat intelligence realistically start at around EUR 150,000.

Which regulatory frameworks require red teaming in Europe?

TIBER-EU and its national implementations (TIBER-AT in Austria, TIBER-DE in Germany and others), the FINMA requirements in Switzerland - and DORA, which has made threat-led penetration testing mandatory for systemically relevant financial entities across the EU since 2025.
