Purple Teaming

Primary Objective

Simulate a real-world adversary to test detection and response under realistic conditions

Improve collaboration between offensive (Red) and defensive (Blue) teams to strengthen defenses

Engagement Style

Stealth-based, covert, minimal defender awareness

Collaborative and transparent with shared visibility

Scope

Broad and goal-driven (e.g., domain compromise, data exfiltration)

Focused on testing and tuning specific defensive controls and detection rules

Defender Involvement

Blue team typically unaware during engagement

Red and Blue teams work together in real time

Detection Testing

Measures whether attacks are detected and how response unfolds

Actively tunes alerts, rules, and response processes during testing

Feedback Cycle

Post-engagement reporting and debrief

Continuous feedback loop during testing

Social Engineering

Often included (phishing, credential harvesting, lateral movement)

May be included, but primarily for defensive tuning and improvement

Timeframe

Weeks to months depending on objectives

Shorter, iterative sessions or ongoing collaborative exercises

Primary Output

Executive-level impact narrative + technical findings

Improved detection rules, playbooks, and response capabilities

Best For

Organizations wanting to test real-world resilience

Organizations focused on improving SOC maturity and detection engineering

Key Question Answered

“Would we detect and stop a real attacker?”

“How can we improve our ability to detect and respond?”
