Tristan Lockwood

Tristan counsels leading technology companies – from the world’s largest online platforms and frontier AI labs to innovative startups and scale-ups – on their most complex regulatory challenges.

Leveraging firsthand insight into transatlantic tech policy, Tristan supports clients across the full compliance life cycle. His practice spans product design, compliance strategy and high-stakes disputes, providing strategic advice on: 

• Artificial intelligence: Global governance, EU AI Act compliance design, European AI Office engagement, and emerging global and US state-level AI frameworks. Tristan translates the technical architecture of AI systems into actionable legal frameworks.
• Online safety and platform liability: EU Digital Services Act (DSA), UK Online Safety Act (OSA), US state laws and frameworks in other emerging jurisdictions, as well as age assurance requirements, service bans and content moderation and reporting obligations (e.g. CSAM, NCII and terror content).
• Law enforcement and lawful access: Navigating government surveillance frameworks, cross-border data requests, intercept laws and the evolving regulatory obligations surrounding end-to-end encryption and user privacy.
• Regulatory engagement and defense: Guiding engagement with EU, UK and global regulators, including defending EU (European Commission and Member State) and UK (Ofcom, ICO) enforcement proceedings.

Before entering private practice, Tristan served as a senior lawyer for the Australian government, advising the national security community at the intersection of technology, free speech, and surveillance. He has extensive litigation experience in complex national security matters, including precedent setting cases on free speech.
