What is purple teaming?
Purple Teaming is a collaborative security testing approach where offensive (Red Team) and defensive (Blue Team) teams work together in real time to test, detect, and improve an organisation’s ability to identify and respond to simulated cyber threats.
Unlike traditional Red Teaming — which is often covert — Purple Team engagements are fully transparent and designed for knowledge sharing and control validation. Each scenario is executed with live feedback and direct collaboration to maximise detection improvements and defensive learning.
Bulletproof enhances this process by providing a dedicated live portal, enabling real-time scenario tracking, evidence logging, and cross-team interaction throughout the engagement. This not only simplifies coordination but ensures the experience is structured, engaging, and easy to manage.
Benefits of purple teaming
Real-time collaboration
Red and Blue Teams operate side by side to execute, detect, and tune defences against each defined scenario.
Faster detection tuning
Immediate feedback allows defenders to adjust, improve and retest their detection logic and response procedures on the spot.
Live attack visibility
Our interactive portal provides real-time visibility into ongoing attack simulations, detection status, and response performance.
Improved defensive maturity
Direct collaboration accelerates Blue Team development and ensures defensive gaps are identified and addressed immediately.
Controlled & structured testing
Scenarios are scoped, tracked, and logged with scenarios and attack plans mapped to the MITRE framework, allowing repeatable testing and long-term detection improvements.
Continuous improvement
Use findings to refine your cyber defence strategy over time, integrating lessons learned into policies, controls, and team training for ongoing resilience gains.
Purple teaming engagement phases
Purple Team engagements are designed to deliver measurable improvements in your organisation’s detection and response capabilities through structured, collaborative testing. Bulletproof’s methodology is built around a phased approach that promotes transparency, continuous feedback, and operational improvement.
Planning and Scenario Selection
We collaborate with your security team to select relevant TTPs or develop custom attack scenarios tailored to your threat profile, defensive tooling, and detection maturity. Scenarios are aligned to frameworks such as MITRE ATT&CK to ensure relevance and traceability.
Live Scenario Execution
Each scenario is executed in a controlled, transparent manner with the Blue Team observing and responding in real time. Activities from both Red and Blue Teams are logged in our interactive engagement portal, providing visibility into detection events, analyst actions, and scenario progression.
Detection Gap Analysis
We assess how each scenario was handled — identifying which events triggered alerts, the speed of detection, the accuracy of escalation, and where gaps exist in telemetry, visibility, or logic.
Retest and Improvement Cycle
Identified quick wins and easily actionable issues are addressed immediately, allowing the Blue Team to update detection logic or response workflows. Scenarios are re-run to validate fixes and confirm improvements before moving to the final reporting phase.
Response Review and Recommendations
Upon completion of all scenario runs, we deliver a final analysis outlining both the immediate improvements achieved and longer-term recommendations. Items that could not be remediated during the engagement are prioritised and documented for ongoing development and future testing cycles.
Learn more about purple team engagements
Yes. Purple Teaming is ideal for organisations looking to develop or refine their detection and response processes. It helps security teams gain hands-on experience in identifying and responding to realistic attack activity.
Purple Teaming engagements are typically delivered over 1 to 2 weeks, depending on the number and complexity of scenarios. The format is highly adaptable based on the maturity and availability of your internal teams.
Bulletproof provides a dedicated interactive portal to coordinate scenarios, log detection activity, and track response actions streamlining collaboration and visibility for all stakeholders.
Absolutely. We can tailor the purple team engagement to focus on specific TTPs, attack chains, or MITRE ATT&CK techniques relevant to your threat model, tooling, or compliance objectives.
