Threat Modelling: Find Risks Before They Become Threats

Table Top Exercise

Firmus provides Threat Modeling services to help organizations proactively identify cybersecurity risks, strengthen security architecture, and align with regulatory and operational cybersecurity requirements. Our approach focuses on integrating security into system design, operational technology (OT), critical infrastructure, and enterprise environments to improve overall cyber resilience.

Threat Modeling is a structured approach to identifying, analyzing, and mitigating potential security threats across applications, systems, infrastructure, and operational environments before exploitation occurs.

Firmus assists organizations in understanding:

  • What assets require protection
  • Who the potential threat actors are
  • How attacks may occur
  • Which controls are required to reduce risk
