A proven purple team approach combining offensive testing with defensive validation to close detection gaps and harden your controls under real attack conditions
Discovery & Planning
Define scope, objectives, and rules of engagement. Align testing approach with your compliance and business goals.
Reconnaissance
Map your attack surface using advanced tooling and threat intelligence to identify potential entry points.
Attack Simulation
Simulate real-world attack chains, including lateral movement and privilege escalation, to expose exploitable paths.
Purple Team Validation
Work side-by-side with your SOC to replay attack sequences, tune SIEM detection rules, and document coverage gaps.
Reporting & Next Steps
Deliver actionable, jargon-free reports with prioritized findings and clear remediation guidance.
