Continuous Purple Teaming for Ongoing Security Validation

🛡️ Continuous purple teaming unites offensive and defensive functions into a collaborative, repeatable cycle that turns testing into measurable defense improvement. Using Breach and Attack Simulation (BAS), teams automate emulations mapped to MITRE ATT&CK, safely execute simulated payloads, and instantly score prevention, detection, and response. That evidence-driven loop—attack, observe, fix, validate, repeat—reduces noise, prioritizes real risk, and accelerates remediation. With careful AI assistance and a curated BAS library, organizations can validate controls continuously and focus on the highest-impact gaps.

Crash Tests for Security: Why BAS Is Essential in 2025

🛡️Breach and Attack Simulation (BAS) acts as a crash test for enterprise security, simulating real adversary behavior to reveal gaps that dashboards and compliance reports often miss. The Blue Report 2025 — based on 160 million adversary simulations — documents falling prevention rates, widespread blind spots in logging and alerting, and near-total failure to stop data exfiltration. By turning posture into validated performance, BAS helps CISOs prioritize remediation, reduce MTTR, and produce auditable evidence of resilience for boards and regulators.

CTEM Focus: Prioritization and Validation in Practice

🔒 Continuous Threat Exposure Management (CTEM) reframes vulnerability work by centering on prioritization and validation instead of treating every scanner finding as equally urgent, helping teams stop chasing volume and start addressing exposures that actually endanger the business. Prioritization ranks issues by real business impact, while validation — via Adversarial Exposure Validation (AEV) technologies like breach and attack simulation and automated penetration testing — proves which gaps are exploitable. This converts assumptions into evidence and enables focused, continuous defense for dynamic environments.

Ransomware Still Evades Defenses Despite Protections

🔒 Picus Security's Blue Report 2025 shows ransomware continues to outpace defenses: overall prevention fell from 69% to 62% year-over-year, while data exfiltration prevention collapsed to just 3%. Both established families (BlackByte, BabLock, Maori) and emerging strains (FAUST, Valak, Magniber) bypass controls using credential theft, fileless techniques and staged execution. Picus recommends continuous Breach and Attack Simulation (BAS) to validate controls, deliver actionable fixes, and provide measurable evidence of readiness.
