Simulation Coverage

Simulation coverage is the percentage of a system's code, functions, or scenarios exercised during cybersecurity testing simulations.

This metric indicates how comprehensively security testing has evaluated potential attack vectors, system vulnerabilities, and defensive responses across an organization's digital infrastructure.

In cybersecurity contexts, simulation coverage typically measures the breadth of penetration testing, red team exercises, or automated security assessments. High coverage means that testing has examined most critical system components, user access points, network segments, and potential threat scenarios. Low coverage suggests significant blind spots where vulnerabilities might remain undetected.

Effective simulation coverage requires mapping all assets, entry points, and critical business processes before testing begins. Organizations often use coverage metrics to identify untested areas that require additional security validation, ensuring that simulations reflect real-world attack patterns and business-critical scenarios.

Comprehensive simulation coverage helps organizations understand their true security posture by revealing how well their defenses perform against various threat scenarios, from basic phishing attempts to sophisticated advanced persistent threats, ultimately improving their overall cybersecurity resilience.
