Traditional security testing often provides only a static snapshot of an organization’s defenses, relying primarily on hypothetical scenarios and vulnerability scanners to identify potential weaknesses. While these methods provide some value, they often fall short in simulating the dynamic and evolving tactics used by real adversaries.
Threat emulation, on the other hand, takes a realistic approach to assessing an organization’s security posture. This advanced testing methodology goes beyond identifying vulnerabilities to evaluate the effectiveness of an organization’s overall defense strategy. By emulating attacker behavior, security teams can prioritize mitigation efforts, optimize resource allocation, and make more informed decisions about cybersecurity investments. Essentially, threat emulation allows organizations to close the gap between their current security posture and the level of protection needed to thwart modern cyber attacks.

Achieving threat-based defense
Threat emulation is a core component of threat-based defense, a proactive cybersecurity strategy aimed at helping security teams prepare for the threats that matter most and develop detailed insights into the effectiveness of their security program. Unlike static vulnerability scanning, threat emulation actively mimics attacker behavior to expose vulnerabilities and potential exploitation paths. This provides a comprehensive view of an organization’s security posture, similar to a cybersecurity audit focused on attacker tactics.
By emulating real-world attacker techniques, including those used by prolific ransomware groups like LockBit and BlackCat, organizations gain critical knowledge to prioritize defenses, optimize resource allocation, and make informed security decisions. This proactive approach enables organizations to anticipate and counter evolving threats.
Threat emulation also facilitates a continuous learning cycle. By regularly testing the organization’s defenses against simulated attacks, security teams can identify gaps, refine their response capabilities, and stay ahead of emerging threats. This iterative process ensures that the organization’s defenses remain aligned with the evolving threat landscape.
Threat emulation can be improved through the use of attack graphs. These visual representations of potential attack paths provide a structured approach to understanding and emulating complex attack scenarios. By incorporating attack graphs into threat emulation programs, organizations can gain deeper insight into adversary tactics, identify critical dependencies, and more effectively prioritize mitigation efforts.
Bridging the gap
Cybercriminals are constantly evolving their methods, making it imperative for organizations to stay ahead. Threat emulation helps bridge the gap between reactive incident response and proactive threat prevention. By regularly testing defenses against emulated attacks, organizations can identify weaknesses, refine their security controls, and reduce the chance of a successful breach.
Additionally, threat emulation provides a tangible return on investment (ROI) for security initiatives. By quantifying the effectiveness of security controls against real-world threats, organizations can make data-driven decisions about resource allocation and investment priorities. This ability to concretely demonstrate the value of security controls is especially valuable when communicating with non-technical stakeholders, such as executives and board members.
Threat emulation is not a standalone solution, but an integral part of a comprehensive cybersecurity strategy. By simulating real-world attacks and providing actionable intelligence, it enables security teams to make informed decisions, prioritize mitigation efforts, and ultimately reduce the risk of a successful cyberattack. As the threat landscape continues to evolve, threat emulation will become increasingly important for organizations of all sizes and across all industries. By embracing threat emulation, organizations can take an important step toward building a more resilient and secure environment.
