Purple Teams Are Just Red & Blue in the Same Room – Operational Gaps Undermine Effective Defense
What Happened — A recent analysis on The Hacker News shows that many “purple” teams are merely co‑located red and blue teams that still operate in silos. Analysts spend valuable time manually copying hashes, rewriting scripts, and waiting on patch approvals that exceed exploitation windows.
Why It Matters for TPRM —
- Inefficient purple‑team workflows can leave critical vulnerabilities unmitigated, increasing third‑party risk.
- A false sense of comprehensive testing may cause organizations to under‑invest in mature detection and response capabilities.
- Vendors that claim robust purple‑team services may not deliver the integrated threat‑hunt and remediation needed for supply‑chain resilience.
Who Is Affected — Technology SaaS providers, MSSPs, MSPs, and any organization that outsources security testing or relies on third‑party purple‑team engagements.
Recommended Actions —
- Validate that purple‑team engagements include defined hand‑off processes, shared tooling, and joint metrics.
- Require vendors to demonstrate automated script sharing and real‑time detection‑to‑response pipelines.
- Incorporate “purple‑team maturity” criteria into vendor risk questionnaires.
Technical Notes — The article highlights process‑level weaknesses rather than a specific vulnerability: manual hash look‑ups, ad‑hoc script rewrites, and patch‑approval windows that outlast exploitation windows. No CVEs or malware are cited. Source: The Hacker News
