National Security

WilmerHale’s national security practice is widely regarded as a market leader, distinguished by its deep bench of experienced professionals and its sophisticated, integrated approach to advising clients operating in highly regulated and geopolitically sensitive sectors. We serve companies across defense, technology, aerospace, government services, and other industries where national security considerations are central to business operations, transactions, and long-term strategy. Our practice is purpose-built for today’s national security environment, recognizing that these issues rarely arise in isolation and instead demand coordinated regulatory, investigative, and litigation capabilities.

A defining feature of our practice is our unmatched cadre of former senior government officials with firsthand experience across the government, including in the intelligence community, shaping and enforcing US national security policy. The team is led by Matt Olsen, former Assistant Attorney General for National Security at the US Department of Justice, whose recent leadership role provides the practice with an unparalleled understanding of current government priorities and regulatory expectations. This government insight ensures that client advice reflects contemporary enforcement realities rather than purely historical precedent.
