MITRE ATT&CK-Aligned Red Teaming & Adversary Simulation
MITRE ATT&CK is a globally accessible knowledge base of adversary tactics and techniques based on real-world observed attacks, organised into a matrix — tactics (the "why," such as Initial Access or Privilege Escalation) across the top, and the specific techniques and sub-techniques attackers use to achieve each one underneath. It has become the shared language for describing what a red team actually did, not just what vulnerabilities they found.
Mutex Systems runs full-scope red team and adversary simulation engagements mapped to MITRE ATT&CK Enterprise and Cloud matrices, testing detection and response capability against realistic, technique-level attack paths rather than a generic penetration test scope.

- Who It's For
- Organisations with a mature security operations function that want to test detection and response capability, not just find vulnerabilities — red teaming assumes some level of existing defence and measures how well it actually holds up.
Core Domains
A Practical Engagement Path
- 01
Scenario Design
Select realistic adversary tactics and techniques relevant to the organisation's actual threat profile — not a generic attack chain.
- 02
Assumed Breach or Full-Scope Simulation
Execute the simulation from an assumed-breach starting point or full external-to-internal chain, mapping every action taken back to its ATT&CK technique ID.
- 03
Detection & Response Measurement
Record what the defending team actually detected and how quickly, providing a technique-level view of detection coverage gaps.
- 04
Purple Team Debrief
Walk through the attack chain with the defending team technique by technique, closing detection gaps in real time rather than waiting for a report weeks later.
Testing Detection, Not Just Prevention
Full-scope adversary simulation across physical, digital, and social engineering vectors, measuring how defences actually perform under a realistic attack rather than just cataloguing vulnerabilities.
- Full-scope engagements aligned to MITRE ATT&CK Enterprise and Cloud matrices
- Assumed-breach, phishing, and physical security scenarios built around realistic adversary behaviour
- Every action mapped to its specific ATT&CK technique ID for a precise, comparable detection-coverage view
Detection-Coverage Gaps Tracked Technique by Technique
grComply records every ATT&CK technique ID exercised during a red team engagement and whether the defending team detected it, giving a persistent, queryable detection-coverage map instead of a snapshot that ages the moment the purple team debrief ends.
- Detection gaps identified during the engagement are raised as tracked observations against the relevant NIST CSF Detect or Respond function, not left as a bullet point in a slide deck
- Coverage improves visibly over successive engagements because the technique-level record persists in the platform between exercises, rather than starting from zero each time
- Board and governance-layer reporting can show detection-coverage trend over time alongside the rest of the organisation's compliance posture
grComply is Mutex Systems' own multi-tenant GRC automation platform — the framework library, hybrid scanning, risk and audit workflow, and AI-assisted compliance behind every point above are live in production today.

What is the difference between MITRE ATT&CK tactics and techniques?
Tactics represent the adversary's objective at a given stage of an attack — for example, Privilege Escalation or Lateral Movement. Techniques (and sub-techniques) are the specific methods used to achieve that objective. A single tactic like Privilege Escalation might be achieved through dozens of different techniques depending on the target environment, each catalogued individually in the matrix.
How is a MITRE ATT&CK-mapped red team engagement different from a standard penetration test?
A conventional penetration test typically aims to find and demonstrate as many exploitable vulnerabilities as possible within a defined scope, often with the target organisation's security team aware testing is happening. A MITRE ATT&CK-mapped red team engagement simulates a realistic adversary chain — often without the defending team's prior knowledge — and measures whether detection and response capability actually catches the activity, not just whether the vulnerabilities exist.
What is MITRE D3FEND?
MITRE D3FEND is a complementary knowledge base to ATT&CK, cataloguing defensive countermeasures and mapping them to the specific offensive techniques they address. It is used to identify detection and mitigation gaps once an ATT&CK-mapped assessment has shown which techniques currently go unnoticed.
Does MITRE ATT&CK cover cloud environments?
Yes. The Enterprise ATT&CK matrix includes a Cloud-specific set of techniques covering platforms such as AWS, Azure, Google Cloud, and Office 365/Entra ID, alongside separate Mobile and ICS (Industrial Control Systems) matrices for those environments.
Does Mutex Systems run MITRE ATT&CK-mapped red team engagements?
Yes. Mutex Systems runs full-scope TIBER-EU and CBEST-style engagements aligned to MITRE ATT&CK Enterprise and Cloud matrices, including assumed-breach, phishing, and physical security scenarios.
