Building a Purple Team Program

From ad-hoc tests to a repeatable program, cadence, scoping to threats that matter, reporting to five audiences, and the metrics leadership cares about.

Program

A purple team program turns one-off exercises into a repeatable engine that measurably improves detection over time.

Scope to threats that matter

Start from the adversaries and techniques most relevant to your industry (ATT&CK's threat-group data helps), not the whole matrix at once. Ransomware, insider threat, and cloud IAM escalation cover a lot of real risk.

Set a cadence

Run on a schedule, monthly technique sprints, quarterly full-chain emulations, and re-run after every detection change to confirm the gap stayed closed. Readiness is a trend line, not a one-time score.

Report to five audiences

Red team, the attack narrative and findings.
Blue team, missed detections and root cause, with recommended rules.
Purple, the joint coverage map and MTTD per technique.
Executive, top gaps, top wins, and the readiness trend.
Compliance, control coverage mapped to NIST CSF, ISO 27001, and more.

Tyrian generates all five report types automatically from one session's evidence, and an AI SOC analyst drafts the triage, so the program's overhead is running the range, not writing documents.
