As digital systems become foundational to economic competitiveness and national security, the United States is advancing a more coordinated and forward-looking approach to cybersecurity. President Trump’s newly released Cyber Strategy for America aims to define how the federal government will partner with the private sector and allies abroad..
On March 19, 2026, Meridian International Center convened a fireside chat featuring White House National Cyber Director Sean Cairncross. The conversation, moderated by Machalagh Carr, Founder & CEO of Quell Strategies, opened with remarks from Jordana Siegel, AWS Head of Cybersecurity and Data Protection Policy for the Americas, and Kellee Wicker, Vice President of the Meridian Center for Technology, Innovation, and Space, as part of the Insights@Meridian series.
Here Were the Top Takeaways from the Program: 1. A Whole-of-Nation Approach The Office of the National Cyber Director (ONCD), established by President Trump in the final days of his administration in January 2021, is designed to coordinate cyber policy across the federal government and to “reestablish” a more strategic relationship with the private sector, which owns and operates most U.S. critical infrastructure. Director Cairncross emphasized that while the strategy creates a whole-of-government framework for policy, implementation must be whole-of-nation: federal agencies, state and local governments, companies, civil society, and individual users all share responsibility for cyber hygiene and resilience. 2.
Reactive Defense to Proactive Deterrence President Trump’s Cyber Strategy for America explicitly aims to change adversaries’ risk calculus by treating major cybercriminal syndicates as transnational criminal organizations, enabling more proactive, long-term disruption using cyber, diplomatic, law enforcement, and economic tools rather than relying primarily on post-incident remediation. Defense alone, the Director emphasized, is no longer sufficient in an environment where adversaries only need to succeed once. 3.
Securing Critical Infrastructure Through Tailored Solutions A major focus of the Cyber Strategy for America is strengthening critical infrastructure, with particular emphasis on sectors such as water and hospitals that remain fragmented, under-resourced, and unevenly regulated. Rather than imposing a one-size-fits-all “50-state solution,” Director Cairncross described plans to launch targeted pilot programs in specific states and localities, partnering with real operators to test and scale technologies—including AI-driven monitoring and defense tools—that can overcome capacity constraints and reduce costs. 4.
Securing Cyberspace through International Collaboration Cybersecurity is inherently a collective challenge, and no nation can meet it alone. Partnerships with Five Eyes nations and allies worldwide remain foundational to global cyber defense, and Director Cairncross extended a direct invitation for partner countries to engage with the U.S. in building shared cyber capacity and resilience. 5. Exporting a “Clean” American Tech Stack Director Cairncross framed the push for a "clean American-plus-allies tech stack" as a central foreign policy objective and a direct counter to the global exportation of the surveillance-state infrastructure.
Responding to concerns about digital sovereignty and data practices of U.S. companies, he argued that such assertions—which are often used to justify the purchase of cheaper technologies from global competitors—are unfounded. For example, while the People’s Republic of China has authority to access data managed by companies based in China, U.S. companies operate under laws and rights that prevent such collection. While acknowledging cost as a real driver for the procurement of such technology, the Director was clear that back-end security savings far outweigh upfront costs for “clean ”, cutting-edge , and trustworthy American technologies.
