Red Teaming as a Service (RTaaS) from Eventus Security is a managed offensive security offering that continuously simulates real-world cyber attacks against an organization's environment. The service runs on a recurring schedule rather than as a one-time engagement, using a combination of human-led red team exercises and automated red teaming tools to identify security weaknesses as environments and threats evolve. The service validates how well existing security measures, controls, and security teams resist actual attack scenarios. It goes beyond traditional security assessments by testing detection, blocking, and containment capabilities in live conditions. RTaaS exercises both blue team defenders and can operate as purple team engagements to measure how quickly defenders spot and respond to simulated attacks. Each assessment cycle produces evidence-driven findings that help organizations prioritize remediation efforts and measure improvements in security posture over time. The service integrates with Eventus Security's SOC operations to provide coordinated detection and response capabilities. RTaaS adapts scenarios based on industry risk profiles and regulatory requirements, delivering metrics suitable for boards and auditors. The continuous nature of the service helps organizations track whether security fixes remain effective against evolving threats, exposing gaps that compliance-driven assessments and routine security testing often miss, including flawed security policies, weak inter-team processes, and untested incident response procedures.
