Sidley Austin LLP

Sidley Austin LLP‘s national security practice is led by David Lashway and Andrew Shoyer and is anchored by a deep bench of Washington DC–based partners with extensive government and private-sector experience. The team is noted for advising multinationals and critical-infrastructure operators on issues at the intersection of regulation, technology, and geopolitics. Shoyer is a leading authority on sanctions, export controls, and treaty-based trade and investment rules, drawing on senior experience at the Office of the USTR and the WTO. Lashway leads the firm’s cybersecurity and data governance capabilities, advising boards and executives on national-security-aligned cyber strategy, ransomware response, and emerging technology risk. Jim Mendenhall focuses on CFIUS, international trade policy, and investment disputes, while Jen Fernandez counsels clients on export controls, OFAC sanctions, ICTS supply chain rules, and outbound investment restrictions. Maura Rezendes, a former OFAC enforcement chief, advises financial institutions and multinational companies on sanctions compliance, enforcement, and licensing matters. Further strengthening the platform, Michael C. Hochman and John Woods bring senior policy and regulatory experience to cybersecurity, data security, and national security compliance mandates.
