Sean Cairncross confirmed as new national cyber director: McCrary reacts

Statement from Frank Cilluffo, director of the McCrary Institute for Cyber and Critical Infrastructure Security, on the Senate confirmation of Sean Cairncross this evening:

I want to extend my congratulations to Sean Cairncross on his confirmation by the United States Senate to serve as the next National Cyber Director. The bipartisan support for his nomination is both encouraging and essential — a clear sign that cybersecurity remains a top national security priority.

The mission of the Office of the National Cyber Director (ONCD) has never been more critical: advancing a unified, strategic, and forward-leaning approach to the cyber threats facing our increasingly digital society.

As a relatively new institution, ONCD continues to evolve. Sean’s leadership, experience, and commitment to public service will be vital to the Office’s growth into the center of gravity for cyber strategy, planning, coordination, and response. I look forward to working with Sean and his team to strengthen our nation’s cyber resilience and readiness.
