Pentera RansomwareReady is an automated validation platform that emulates ransomware attacks to test organizational defenses. The platform applies safe versions of real-world ransomware strains including REvil, Conti, Maze, and LockBit 2.0 to assess security posture without causing operational disruption. The platform operates through agentless deployment on existing Pentera nodes, requiring no special hardware beyond standard configurations. It emulates ransomware behaviors across Windows and Linux systems, testing initial exploitation, payload execution, encryption, and data exfiltration techniques. All attack simulations are aligned to the MITRE ATT&CK framework. RansomwareReady validates endpoint protection efficacy by testing whether security controls can detect and block ransomware activities. It identifies vulnerable hosts, lateral movement pathways, and potential attack vectors that ransomware could exploit to reach critical assets. The platform encrypts duplicate files rather than production data to ensure safe testing. The platform provides step-by-step remediation guidance prioritized by business risk. It identifies security gaps in endpoint detection and response capabilities, SOC detection and response procedures, network segmentation, privilege management, and access controls. Testing results help organizations understand where defenses are insufficient and what actions are needed to prevent ransomware propagation.
