Cyber organizations invest significant resources in defending networks, training personnel, and modernizing cyber capabilities. Yet many of the same attack paths continue to succeed year after year.
There is a reason for that. Most organizations understand where vulnerabilities exist, but they do not always understand how a determined adversary would exploit them in a real operational environment.
Years ago, someone told me to start every cyber threat intelligence discussion with a quote from Sun Tzu. It became a running joke over time, but one principle still applies to adversary emulation today: “Know your enemy and know yourself.”
Cyber adversary emulation has advanced significantly in recent years. Modern red teams do far more than test isolated vulnerabilities. They replicate how real-world adversaries gain access, move through environments, pivot across systems, and maintain persistence over time using increasingly realistic tradecraft.
At the same time, cyber defense operators are training against the tactics, techniques, and procedures (TTPs) they are most likely to encounter in operational environments. That type of realistic preparation matters. Teams that train against authentic threat behavior are better positioned to identify malicious activity early and respond effectively under pressure.
While adversary emulation capabilities continue to mature, many organizations still see the same attack paths succeed across multiple engagements. That trend points to a larger challenge: turning adversary emulation into lasting defensive improvement.
Most organizations do not lack findings. They lack systemic change.
Too often, remediation efforts focus only on the immediate point of failure while the broader conditions that enabled the intrusion remain in place. As a result, the same weaknesses continue to appear during future assessments and exercises.
As federal organizations prepare for increasingly contested operating environments, adversary emulation provides an opportunity to move beyond checklist-driven assessments and evaluate how people, processes, and technologies perform under realistic conditions.
A common scenario illustrates the problem. A red team gains access through a low-privilege account connected to a legacy system. Weak service account permissions then allow lateral movement and eventual privilege escalation through native protocols.
This is not a particularly advanced attack path, but it continues to succeed because the underlying conditions persist across environments.
Cyber defense operators and system owners must be empowered to address these recurring weaknesses before they become repeatable avenues for compromise. Organizations improve when they remove the predictable opportunities adversaries rely on most.
The ultimate objective is not simply identifying vulnerabilities. It is improving mission readiness by helping defenders recognize, respond to, and disrupt adversary activity before mission impact occurs.

The environments that improve over time treat adversary emulation as more than a compliance exercise. They use it as operational input for detection engineering, defensive refinement, and mission readiness.
Effective teams break down how access was achieved, identify recurring patterns, and build detection logic around those behaviors. Detection is not assumed. It is deliberately engineered using available threat intelligence and operational observations from contested cyber environments.
Teams should continuously evaluate whether malicious activity should have been visible. If it was not, they must identify where telemetry, visibility, or correlation gaps exist.
Validation is equally important. Detections must be tested under realistic conditions to confirm they are timely, actionable, and capable of supporting operational decision-making when it matters most.
Over time, this approach reduces repeatable attack paths, improves detection timing, and limits adversary freedom of movement across the environment.
Emerging technologies, AI-enabled capabilities, and increasingly complex mission environments are creating new opportunities for both defenders and adversaries.
Organizations are rapidly modernizing networks, adopting new platforms, and integrating advanced technologies to improve operational effectiveness. However, modernization alone does not guarantee resilience.
New capabilities must be tested against realistic threat behavior rather than assumed secure by design.
Adversary emulation provides a practical mechanism for validating whether defensive investments, detection capabilities, and operational processes perform as intended under realistic conditions. It helps organizations understand not only where vulnerabilities exist, but also how those vulnerabilities could affect mission execution if exploited by a capable adversary.
As cyber environments continue to evolve, realistic testing becomes increasingly important to ensuring that modernization efforts deliver measurable operational outcomes.
Adversary emulation has already demonstrated what is possible in modern cyber operations. Its value comes from ensuring those same attack paths do not remain available in the future.
Organizations that fully leverage adversary emulation can strengthen operational resilience, improve defensive performance, and better prepare their teams for real-world threats. The closer operators can replicate near-peer adversary behavior, the more effective defenders become at recognizing and disrupting it.
Preparation alone is not enough. The real advantage comes from applying lessons learned and continuously improving defensive posture over time.
The most effective organizations do not view adversary emulation as a periodic assessment. They treat it as a continuous mechanism for improving mission readiness, validating defensive investments, and strengthening operational resilience.
The objective is not simply to understand how an adversary might attack. It is to ensure that when they do, the mission continues.
As cyber leaders evaluate mission readiness, AI-enabled operations, and the resilience of increasingly complex environments, adversary emulation will remain an essential tool for validating performance under realistic conditions.
As military and federal organizations prepare for increasingly contested environments, the ability to validate defenses against realistic adversary behavior has become a critical component of mission readiness.
At AFCEA TechNet Augusta, Markon, Millennium, and PLEX will be engaging with government and industry leaders on adversary emulation, cyber readiness, AI-enabled operations, and resilient mission environments.
We look forward to discussing how organizations can move beyond identifying vulnerabilities and begin turning adversary emulation into measurable operational advantage.
