Coalfire's Threat Modeling and Attack Simulation (TMAS) helps organizations validate their security effectiveness through purple team simulations that represent both attacker and defender postures. It identifies low-priority, overlooked, and unexpected threat vectors by evaluating risk management strategies, identifying potential threats, developing attack simulations based on the MITRE ATT&CK framework, and executing attacks to assess security strengths and weaknesses. The product provides a threat model unique to each business, addressing various attack scenarios such as insider threats, compromised customer accounts, supply chain compromises, malware-infected workstations, spear-phishing, and physical attacks. TMAS testers can simulate attacks through physical access, social engineering, technical attacks, or non-traditional IoT solutions, complementing initiatives like vulnerability assessments and defensive diagnostics to enhance security operations.
