Pen test, red team or purple team — which do we need?

Pen tests validate specific scope and compliance. Red teams stress-test detection and response against real objectives. Purple teams close gaps collaboratively. Most mature programmes need all three, at different cadences.

How often should we run offensive exercises?

Annual external pen test, quarterly targeted assessments on high-value assets, and at least one full red team engagement per year for critical business functions.

Is a red team useful before we have a mature SOC?

Purple teaming is the better first step — it builds detections and playbooks. Red teaming pays off once you have defenders and telemetry worth testing.

Pen Test vs Red Team vs Purple Team: What Actually Improves Your Defences

Three offensive security engagements, three very different outcomes. A CISO's guide to when to run each — and how to measure real defensive uplift.

"We got a pen test, we're fine" is the most dangerous sentence in security. Pen tests, red teams, and purple teams answer different questions.

The three engagements

Penetration test

Question: Can a motivated attacker exploit this scope in this time window? Scope: Narrow (an app, a network segment, a cloud tenant). Deliverable: A findings report with CVSS scores and remediation guidance. Cadence: Annual for compliance; per-release for critical apps.

Red team

Question: Can we achieve a defined crown-jewel objective without being caught? Scope: Full-stack, adversary-emulated, often multi-week. Deliverable: Attack path narrative, detection gaps, control failures. Cadence: Annual, or after major architectural change.

Purple team

Question: Can our detections actually fire against these techniques? Scope: Collaborative — red executes, blue observes and tunes in real time. Deliverable: ATT&CK coverage heatmap, tuned detections, playbook updates. Cadence: Quarterly, per detection engineering sprint.

Which one first?

No mature SOC? Start with a pen test — fix the obvious.
SOC in place, unknown detection quality? Purple team.
Mature programme, board demands assurance? Red team.

What "good" looks like

Threat-led scoping aligned to your top 5 risks, not a generic checklist.
Assumed-breach scenarios — start on the inside; that's where real attackers get to fast.
Measured outcomes: MTTD, MTTR, ATT&CK coverage delta, control failure rate.
Retest cycles — every finding is retested until closed.

How Solvin Globaltech helps

Our Offensive Security practice delivers pen testing, red team, purple team, and adversary simulation. Findings flow into our Managed Vulnerability Detection & Remediation service for closed-loop remediation.
