Attack simulation is a proactive cybersecurity process that evaluates an organization's defensive capabilities by mimicking real-world cyber threats in a controlled environment. This security practice systematically replicates the tactics, techniques, and procedures (TTPs) used by malicious actors—ranging from phishing campaigns to sophisticated network intrusions—to identify vulnerabilities in technical systems, human processes, and security controls.

By emulating diverse attack scenarios, organizations can assess the effectiveness of their protective measures, detection mechanisms, and incident response frameworks. The insights gained enable security teams to validate their understanding of current threat landscapes, refine defense strategies, and prioritize remediation efforts, ultimately enhancing organizational resilience and reducing the likelihood of successful cyberattacks.
