Mitigant is a cloud security validation platform that performs adversary emulation and attack simulation in cloud environments. The platform executes real attack scenarios to test security defenses across AWS, Azure, and Kubernetes environments. The platform provides over 200 pre-built attack scenarios mapped to MITRE ATT&CK and MITRE ATLAS frameworks. Attack scenarios are informed by cyber threat intelligence and can be executed on-demand or continuously. Users can create custom attacks using the Attack Builder functionality. Attack execution includes safety controls such as Bring Your Own Role (BYOR) for permission management, isolated attack execution, and automatic cleanup to prevent residual impact. The platform validates whether SIEM, CDR, and cloud detection mechanisms detect simulated attacks. AI capabilities analyze cloud posture to identify exploitable weaknesses and generate executive intelligence reports. Results include prioritized remediation guidance, MITRE ATT&CK/ATLAS technique mapping, and Sigma detection rules. The platform includes cloud security posture management functionality that monitors for misconfigurations and compliance violations across CIS Benchmarks, NIS2, DORA, NIST, PCI-DSS, and SOC 2. It provides continuous asset inventory, drift management, and vulnerability intelligence from EPSS and CISA KEV. The platform offers an Attack API and Attack-as-Code capabilities for integration into security workflows and Detection-as-Code practices. It supports AI workload testing through AI Red Teaming capabilities.
