Red and purple teaming

Test your defences against a real adversary.

Technology and processes only prove their worth under pressure. Nomios puts them to the test — simulating real attacks to find what breaks, and working with your team to make sure it doesn't happen again.

Introduction

Beyond compliance testing

Penetration testing tells you where the gaps are. Red and purple teaming tells you whether your organisation — your people, your processes, your detection capability — would actually hold up against a determined attacker. That is a fundamentally different question, and one that matters more as your security programme matures.

Two disciplines. One goal.

Attack. Detect. Improve.

Red team

Full-scope adversary simulation

A covert, objective-led attack against your organisation — no prior warning, no defined scope boundaries. Our red team operates exactly as a real threat actor would, using the same tools, techniques, and patience.

  • Threat intelligence-led scenario planning
  • Multi-vector attack chains — network, identity, social
  • Command & control infrastructure simulation
  • Lateral movement & objective attainment


Purple team

Collaborative detection validation

A transparent, joint exercise where our attackers and your defenders work side by side — running attack techniques in real time and immediately validating whether your detection and response capability catches them.

  • MITRE ATT&CK-mapped attack execution
  • Live detection gap identification
  • Real-time SOC and analyst feedback
  • Detection rule tuning during the exercise
  • Measurable improvement before you leave the room
Why Nomios

Attack and defend — under one roof

Offence informed by defence

Our red teamers understand how SOCs work — and our SOC analysts understand how attackers think. That shared knowledge makes both disciplines sharper.

Findings that feed your programme

Red and purple team outputs connect directly into vulnerability management, detection engineering, and incident response — not just a report that sits on a shelf

TIBER-EU and DORA aligned

For financial sector organisations with threat-led penetration testing obligations, our engagements are structured to meet TIBER-EU and DORA TLPT requirements.

Real improvement, not just a score

We measure success by how much better your defences are at the end of an engagement — not by the number of findings in a report.

Purple teaming works best when your SOC is already running.

Get the most from collaborative exercises by pairing them with Nomios Guardian xMDR — our analysts participate directly in purple team sessions, and detection improvements are deployed into your live environment immediately.
