National Security & Corporate Espionage

We support global companies, investors, and government contractors in identifying, mitigating, and responding to national security, cyber, and espionage risks that affect the decisions critical to their businesses. Drawing on our extensive senior government experience, we advise clients on transactions, investigations, crises, and regulatory matters where security risk, technology, and geopolitics converge.

Our lawyers bring a proactive and holistic approach to managing national security and espionage risk, integrating legal, political, regulatory, and technical insight into some of the most sensitive, existential, and high‑stakes matters companies face. We regularly advise clients as they expand into foreign markets, assess major transactions, address supply chain vulnerabilities, navigate foreign investment reviews, respond to cyber and security incidents, and engage with law enforcement, regulators, and Congress.

We advise a broad range of global clients, including:

  • Public and private companies
  • Private equity sponsors and investors
  • Defense, technology, and life sciences companies
  • Financial institutions and government contractors
  • Companies operating in national‑security‑sensitive industries involving technology, trade, cyber, defense, munitions, and supply chains

Our team counsels our clients across the full spectrum of national security and corporate espionage matters, including:

  • Risk assessment and mitigation for key assets, operations, and expanding global footprints
  • Engagement with law enforcement and the intelligence community, in furtherance of strategic shaping of narratives and profiles, including referrals and coordination to address known or emerging threats
  • CFIUS and foreign investment reviews, including risk analysis, mandatory and voluntary filings, and securing clearance for highly sensitive transactions
  • M&A and private equity transactions, with early collaboration throughout the deal lifecycle and portfolio company management
  • Cybersecurity and security incidents, including crisis response, communications strategy, regulatory engagement, and subsequent litigation
  • Government investigations and enforcement, including False Claims Act matters, congressional oversight investigations, and related litigation
  • Trade, sanctions, and export controls, including proceedings involving export controls and economic sanctions

Our practice is distinguished by depth of experience at the highest levels of government and an integrated, multidisciplinary platform:

  • Our team includes more than 100 former senior U.S. government officials, including former officials from the FBI, CIA, ODNI, DOJ, and USTR.
  • We bring extensive regulatory reach, with regular practice before OFAC, DOJ, Commerce (BIS), DDTC, CFIUS, DOD, DHS, NSC, and international counterparts in the UK and EU.
  • We have handled incident response across hundreds of matters, including some of the most prominent security breaches in the U.S.
  • Our team has proven litigation capabilities, having successfully defended high‑profile investigations and related shareholder, class action, and trade secret theft litigation.
  • We collaborate with our colleagues across the firm in our leading Data, Privacy & Security; Special Matters & Government Investigations; International Trade; CFIUS; Government Advocacy & Public Policy; Intellectual Property; and M&A practices.
