Purple Teaming Sessions
Joint offensive and defensive exercises that turn findings into durable detection and response improvements.
Collaboration between Red and Blue teams for continuous security improvement.
Why teams engage us
Red team reports age quickly if blue team never gets to validate detections in real time. Purple teaming closes the loop: defenders see what telemetry should look like, engineers tune rules without guesswork, and leadership sees measurable progress between major assessments.
What we deliver
We facilitate structured purple sessions where offensive techniques are executed transparently (or semi-blind, per your maturity) while defenders validate alerts, playbooks, and tooling. Each session produces documented outcomes: new or tuned detections, logging gaps, ownership, and follow-up tests.
How we run it
- Planning: pick ATT&CK-aligned techniques or prior red team themes
- Dry run: validate safety and observability in lab or narrow scope
- Live iteration: execute, observe, tune, repeat
- Documentation: detection logic, data sources, and test cases
- Retention option: quarterly technique rotations
Outcomes you can expect
- Concrete improvements to SIEM rules, EDR policies, or data pipelines
- Shared understanding between offensive and defensive staff
- Measurable session metrics: coverage, time-to-detect, time-to-contain
- Roadmap of detection engineering backlog items

FAQ
Do we need a mature SOC?
No, but expectations differ. Less mature teams focus on visibility and basic alerting; mature teams tune correlation and automate response. We calibrate difficulty accordingly.
Purple team vs red team, which first?
Often red team reveals systemic gaps; purple team hardens specific paths. Some organizations start purple to build fundamentals before a broader red engagement.
Can vendors participate?
Yes, when it accelerates tuning (for example EDR or SIEM vendors). NDAs and data handling are agreed up front.
