The Davidson Window: An Urgent Cyber Call to Action

Time is the most unforgiving variable in warfare—the one resource commanders always need more of. Nearly four years ago, Admiral Phil Davidson issued a chilling warning to the Senate Armed Services Committee: China could attempt to retake Taiwan by 2027.

This forecast, now referred to as the “Davidson Window,” has galvanized military and national security leaders to reassess how prepared we truly are—not just in terms of boots on the ground or ships at sea, but in the domain where tomorrow’s conflicts will be decided: cyberspace.

In the face of increasingly sophisticated cyber capabilities from China, the Davidson Window has become more than just a strategic timeline—it’s a countdown clock demanding immediate action.

From my experience in the Marine Corps, I’ve learned that the most important catalyst for real change is a senior leader’s ability to create a sense of urgency. That moment is now.

Understanding the Davidson Window

I would be surprised if every O-4, Major, and Lieutenant Commander in the U.S. Armed Forces hasn’t read John Kotter’s Leading Change. Kotter outlines an eight-step process for leading organizational change, and I often found myself reviewing the process throughout my Marine Corps career.

Since retiring from the Marines, the framework continues to serve me well—and I often sense senior leaders are using it to spur initiatives and drive organizational change.

The first step in Kotter’s model, in my opinion, is the most important step for a senior leader to have the greatest impact: “creating a sense of urgency” to change an organization’s direction. Admiral Davidson did this on March 9, 2021, when he testified before Congress about China’s potential actions regarding Taiwan. Since then, his remarks have instilled a greater sense of urgency within the Department of Defense (DoD), particularly among the Navy and Marine Corps, and established the Davidson Window as a common purpose.

Earlier this year, I attended the DON IT West/AFCEA-West event in San Diego, where many panelists and keynote speakers referenced the Davidson Window. The focus during the event was on readiness and being prepared to “fight tonight”—discussing what can be done now to close gaps, enhance lethality, and strengthen defensive capabilities. After speaking with several attendees, there was a strong sense of urgency—a feeling that time is running out.

The cyber threat is real—and growing

China’s advancements in cyber warfare and its aggressive posture in the digital domain pose significant threats to our infrastructure, economy, and national security. The potential for cyberattacks targeting critical systems, such as power grids, financial institutions, and communication networks, underscores the need for robust cyber defenses.

We are at an inflection point that demands enhanced cybersecurity readiness, lethality, and defense of the communication infrastructure the military relies on—the critical enabler for all warfighting functions.

It is difficult to imagine an element of warfighting that does not rely on or is not enabled by information technology. The warfighter relies on communications networks that extend from the United States to the forward edges of the battlefield. These networks support everything from troop movements and supply chain operations to the command and control of force movements and targeting.

As a result, the U.S. continues to invest in more IT that must be secured, operated, and defended. The technology employed is a force multiplier, but it also creates another attack surface that must be vigorously defended.

Since the Davidson Window is quickly closing, how can the DoD gain real-time visibility and control of their environment with certainty?

The answer is Tanium.

The final countdown: Seizing the cyber advantage

The Davidson Window is closing fast. It is no longer a distant warning on the horizon; it is a rapidly approaching inflection point that will test the readiness, adaptability, and cyber resilience of our national defense.

Cyber warfare will not wait for traditional battle lines—it will strike through code, infrastructure, and misinformation, most likely before the first kinetic shot is fired.

This window serves as a stark reminder of the urgency to prepare for potential conflict with China in 2027. For the DoD to stay ahead of the threat, it must embrace solutions that offer real-time visibility, operational certainty, and unified control across the digital battlefield. The time to act is now. Every day lost is ground ceded to our adversaries.

Let the Davidson Window be our rallying cry—not a retrospective regret.
