Purple Team Assessment
A classic pentest finds vulnerabilities but doesn't check if your SOC sees them. Purple Team combines attack simulation with detection verification — for each MITRE ATT&CK technique we check: did SIEM/EDR generate an alert? Did the SOC respond? Result: concrete detection rules, not just a vulnerability report.

What is a Purple Team Assessment?
A Purple Team Assessment is a security exercise combining Red Team (attack simulation) with Blue Team (defense) in a single coordinated process. Instead of testing defenses in isolation, Red and Blue Teams collaborate in real-time — attackers execute MITRE ATT&CK techniques while defenders verify detection and response. Result: mapped detection gaps and concrete rules to implement.

| Deliverable | ATT&CK coverage map + detection rules |
A classic pentest finds vulnerabilities. Red Team tests defenses. Purple Team goes further — it tests detection and fixes gaps live.
Pentests Don’t Check If Your SOC Sees the Attack
You have a SOC, SIEM, EDR — but do they see everything? Most attack techniques remain invisible to SOC without Purple Team. A pentest will say “you can be breached here and here,” but won’t say “your SIEM doesn’t see lateral movement via PsExec.”
Without Purple Team:
- You don’t know which attack techniques SOC/SIEM fails to detect
- Detection rules may have gaps — nobody tested them
- Blue Team doesn’t know what real attacks look like
- SOC/SIEM investment without effectiveness validation
Red + Blue = Purple — Collaboration, Not Confrontation
In a Purple Team Assessment, Red Team and Blue Team work together, not against each other. For each ATT&CK technique:
- Red executes the technique in a controlled manner
- Blue verifies — did an alert appear?
- If not — they jointly create a detection rule
- Re-test — Red repeats, Blue confirms detection
What you get:
- MITRE ATT&CK coverage map: what SIEM/EDR sees vs doesn’t
- Ready detection rules: Sigma/Splunk/KQL for identified gaps
- Improvement plan: gap prioritization by risk
- Blue Team training: learning from Red Team in real-time
- Metrics: ATT&CK coverage before and after Purple Team
How Purple Team Sessions Work
Each Purple Team session is precisely planned and grounded in the MITRE ATT&CK framework, incorporating threat intelligence specific to the client’s industry.
Threat profiling — before the exercise begins, we analyze APT group profiles active in the client’s sector (e.g., for financial services: FIN7, Carbanak; for energy: Sandworm, Dragonfly). Based on this analysis, we select 30-80 ATT&CK techniques covering the full attack chain: Initial Access, Execution, Persistence, Privilege Escalation, Defense Evasion, Credential Access, Discovery, Lateral Movement, Collection, and Exfiltration.
Execution sessions run 4-8 hours each and follow an iterative cycle. Red Team uses tools such as Cobalt Strike, Mythic C2, Impacket, Rubeus, and Mimikatz to replicate techniques in a controlled environment. Blue Team monitors real-time logs from SIEM (Splunk, Microsoft Sentinel, QRadar), EDR (CrowdStrike, SentinelOne, Microsoft Defender), and NDR. For each technique we document the result: detected / partially detected / not detected.
Live remediation — when Blue Team fails to detect a technique, we collaboratively build a detection rule. We deliver rules in multiple formats: Sigma (universal), SPL (Splunk), KQL (Microsoft Sentinel), and AQL (QRadar). Red Team repeats the technique to confirm the new rule’s effectiveness. This means the organization exits Purple Team with immediately deployed improvements, not just a report.
Final report includes a MITRE ATT&CK Navigator coverage matrix visualizing the state before and after the exercise, all delivered detection rules, and a prioritized improvement plan for techniques requiring architectural changes rather than rule-based detection.

How do you reduce mean time to detect (MTTD)? The four segments where the clock stands still
A company that 'shortened its MTTD' by buying a faster correlation engine usually shortened the shortest leg of the whole route. We break detection time into four parts, show the lever that belongs to each, and describe an honest measurement method — together with what this metric does not measure.
Read more →Is SIEM enough for NIS2? What remains after the tool is deployed
SIEM collects and correlates data, and that is a genuine statutory requirement. Incident handling, however, is a process with staffing, a qualification threshold and a clock that starts at detection. This text separates the two and shows what is left to add.

Common questions about Purple Team Assessment.
How does Purple Team differ from Red Team?
Red Team tests in isolation — attacking and seeing what can be breached. Purple Team is collaboration: Red executes a technique, Blue verifies detection, they jointly fix gaps. Red Team delivers a vulnerability report; Purple Team delivers a detection coverage map.
Do we need our own Blue Team?
Ideally yes — then Purple Team trains your team. If you don't have a Blue Team, the service covers both sides — Red and Blue. We recommend Purple Team for organizations with SOC (internal or outsourced).
How long does a Purple Team Assessment take?
A typical Purple Team is 2-4 weeks: 1 week preparation, 1-2 weeks execution (4-8h sessions), 1 week reporting. Number of ATT&CK techniques: 30-80 depending on scope.
What's the outcome of a Purple Team?
MITRE ATT&CK coverage map (what SIEM/EDR sees vs doesn't), ready detection rules (Sigma/Splunk/KQL), risk-prioritized detection improvement plan.
