Project Glasswing is a reminder of something many in the federal cybersecurity community already know but don’t always say out loud:

We are never going to patch fast enough.

Not across the scale and complexity of federal environments. Not with the volume of known exploited vulnerabilities (KEVs) continuing to grow. And certainly not in operational technology (OT) environments, where patching can introduce as much risk as it mitigates.

This is not a failure of effort, but a structural reality.

Federal networks are vast, heterogeneous, and deeply interconnected. Many systems are mission-critical, some are decades old, and patching cycles are routinely measured in weeks or months when they can happen at all.

Meanwhile, adversaries operate on entirely different timelines. They weaponize vulnerabilities in hours. They automate exploitation. And increasingly, they aren’t just looking to exfiltrate data, they are positioning themselves for operational disruption.

We operate on patch cycles measured in weeks against adversaries operating on exploit cycles measured in hours. That asymmetry matters.

The attacker, after all, needs only one unpatched vulnerability to gain a foothold. From there the focus shifts to moving laterally, escalating privileges, and expanding control.

This is precisely where the traditional model begins to break down. For years, we have treated patching as the primary mechanism for reducing risk. And while patching remains essential, it is no longer sufficient as the foundation of our defensive strategy. Because patching does not prevent initial compromise. And more importantly, it does not stop what happens next.

Shifting the Model: From Prevention to Resilience

If we accept that compromise is inevitable, and in many environments, then the real question becomes: What happens after the initial breach?

This is where we need to fundamentally shift our approach. Success should not be measured solely by how quickly we patch a vulnerability. It should be measured by whether a compromised system can impact anything beyond itself. In other words: Can the adversary move?

Microsegmentation: Controlling the Blast Radius

Granular microsegmentation changes the equation.

Instead of relying solely on eliminating vulnerabilities before they are exploited, microsegmentation assumes that some vulnerabilities will persist. The focus shifts to containing their impact rather than racing to close every gap.

By creating policy-driven, asset-level micro-perimeters, agencies can:

• Restrict communication to only what is explicitly required
• Enforce least-privilege access across east-west traffic
• Prevent unauthorized lateral movement between systems
• Isolate vulnerable or high-risk assets without disrupting operations

The result is a fundamentally different security outcome. A compromised system is no longer a pathway to broader network access but instead becomes a contained event. Even known exploited vulnerabilities lose their operational leverage because they simply cannot move laterally.

Why This Matters for OT and Critical Infrastructure

This shift is especially critical in OT environments. Many systems in these settings cannot be patched quickly, cannot be taken offline without significant operational impact, and were never designed with modern security controls in mind.

In these environments, waiting on a patch cycle is simply not a viable risk strategy, which is why resilience must serve as the organizing principle instead.

Microsegmentation allows agencies to buy time by isolating vulnerable systems, controlling access pathways, and ensuring that critical operations can continue even in the presence of active compromise. In OT environments, the objective extends beyond security in the conventional sense. It is, above all, continuity of operations.

The Path Forward

Project Glasswing doesn’t signal a new problem. It reinforces an existing one: We are not going to outpace our adversaries through patching alone.

But we can change the conditions of the fight.

We can build environments where:

• A single compromised credential does not expose an entire network
• A vulnerable system does not become a launch point for disruption
• A breach does not equate to mission failure

We may not be able to prevent every intrusion. But we can absolutely prevent it from spreading. And in today’s threat environment, that is what resilience looks like.
