Part of Adversary insights →Purple teaming explained: turn attack techniques into measurable detection improvement
How a collaborative purple team exercise helps attackers and defenders measure coverage, tune detections and build a verified improvement backlog.

Need an acronym translated?Open the cyber glossary →Purple teaming is collaborative by design
A purple team exercise brings offensive operators and defenders together around agreed attack techniques. Instead of preserving secrecy throughout the engagement, both sides observe what happens, compare expected and actual telemetry and improve controls while the evidence is fresh.
It answers a different question from red teaming
A red teami normally operates covertly to measure whether a realistic objective can be reached before detection and containment. Purple teaming asks which techniques are visible, whether alerts contain enough context and how prevention, detection and response can be improved technique by technique. Neither model is automatically better; they support different resilience decisions.
Relevant threats should shape the exercise
Technique selection should reflect the organisation's sector, technology, likely adversaries and important business services. Mapping activity to MITRE ATT&CKi supports a shared vocabulary, but the goal is not to maximise a coverage percentage. It is to test the techniques that would materially affect the organisation.
Measure the complete defensive chain
Useful measures include whether an action was prevented, logged, alerted, investigated and contained; the quality of the evidence; and the time taken at each stage. A control can generate telemetry without producing a useful alert, and an alert can fire without enabling an effective response.
Finish with tuning, ownership and replay
The exercise should produce tested detection changes, documented evidence and a prioritised improvement backlog with owners. Replaying missed or weakly detected techniques proves whether the changes work. The Pentesys Portal retains the scope, technique evidence, actions and replay status in one controlled record.
This guide covers the essentials. Continue into our technical analysis for a firmer position, practical implications and recommended action.
