Purple Team
Collaborative Defence

Structured exercises that bring offensive and defensive teams together in real-time to validate detection logic, close coverage gaps and build measurable resilience.

Purple Team Exercises

Simbix LLP Purple Teaming

Purple Team exercises bridge the gap between offensive testing and defensive operations. Rather than running a covert Red Team campaign and delivering findings weeks later, Purple Teaming embeds attackers and defenders in the same room — executing techniques in real-time while the blue team tunes detections on the spot.

Our methodology is mapped to the MITRE ATT&CK framework, ensuring every technique tested has a corresponding detection rule validated, tuned or created during the exercise. The result is immediate, measurable improvement in your security monitoring capability.

Exercise Framework

  • MITRE ATT&CK Technique Coverage
  • Real-Time Detection Validation
  • SIEM Rule Tuning & Creation
  • EDR Bypass & Detection Testing
  • Sigma Rule Development

Atomic Testing

Executing individual ATT&CK techniques in isolation — credential dumping, registry persistence, scheduled tasks — to validate each detection rule fires correctly and with minimal false positives.

Coverage Heatmapping

Building a live ATT&CK heatmap that visualises your detection coverage by tactic and technique, identifying blind spots and prioritising engineering effort where it matters most.

Playbook Validation

Testing incident response playbooks under realistic conditions to measure analyst decision-making, escalation accuracy and containment speed against simulated threats.

Continuous Purple Teaming

One-off exercises deliver point-in-time value. Our Continuous Purple Team retainer embeds regular testing cadences into your security operations calendar — monthly technique sprints that keep pace with evolving threats and infrastructure changes.

Each sprint delivers an updated ATT&CK coverage matrix, new or tuned detection rules, and a prioritised backlog for the next cycle. Your security posture compounds over time instead of degrading between annual assessments.
