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 offer some value, they often fall short in simulating the dynamic and evolving tactics employed by real-world 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 behaviors, security teams can prioritize mitigation efforts, optimize resource allocation, and make more informed decisions about cybersecurity investments. In essence, threat emulation empowers organizations to close the gap between their current security posture and the level of protection required to thwart modern cyberattacks.

Achieving a threat-informed defense
Threat emulation is a core component of threat-informed defense, a proactive cybersecurity strategy focused on helping security teams prepare for the threats that matter most, and on developing granular visibility into their security program's effectiveness. Unlike static vulnerability scans, threat emulation actively mimics attacker behaviors to expose vulnerabilities and potential exploitation paths. This provides a comprehensive view of an organization's security posture, akin to a cybersecurity audit focused on attacker tactics.
By emulating real-world attacker techniques, including those employed 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 empowers 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 defense mechanisms remain aligned with the evolving threat landscape.
Threat emulation can be enhanced 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 insights into adversary tactics, identify critical dependencies, and prioritize mitigation efforts more effectively.
Bridging the gap
Cybercriminals are constantly evolving their methods, making it imperative for organizations to stay ahead of the curve. 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 likelihood of a successful breach.
Moreover, threat emulation offers 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 demonstrate the value of security controls in concrete terms is particularly valuable when communicating with non-technical stakeholders, such as executives and board members.
Threat emulation is not a standalone solution but an integral component of a comprehensive cybersecurity strategy. By simulating real-world attacks and providing actionable intelligence, it empowers 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 critical for organizations of all sizes and industries. By embracing threat emulation, organizations can take a significant step toward building a more resilient and secure environment.
