Vishnu Shankar
Vishnu Shankar, a partner in our London and Brussels offices, brings deep advisory, incident response, strategic crisis management, and regulatory defence and litigation capabilities in complex EU and UK data protection and privacy (GDPR; EU Data Act), artificial intelligence (EU AI Act), cybersecurity and operational resilience (NIS; Cyber Resilience Act), international data transfers (including Binding Corporate Rules), content moderation (EU Digital Services Act; UK Online Safety Act), and other digital regulatory matters. He has served as Head of Legal (Regulatory Enforcement) at the Information Commissioner’s Office (ICO), a leading European data protection regulator. Vishnu has defended clients in landmark GDPR enforcement actions involving AI/machine learning. Active in the firm’s India Initiative, Vishnu serves as a strategic counsellor to India-based companies in international disputes, investigations, and transactional matters. He is admitted in England and Wales, Brussels, and New York.
Vishnu represents clients in high-stakes EU and UK privacy and cybersecurity advisory, compliance, enforcement defense, crisis management, data breach and incident response, and litigation matters. The Legal 500 UK has noted that Vishnu has “excellent attention to detail, an amazing work ethic and tremendous research skills.” Vishnu is also a member of Morgan Lewis’s AI Task Force, Global Conflicts Task Force, and India initiative, where he serves as a strategic counsellor in a variety of industries.
Vishnu represents clients in multiple industries and sectors, including financial services (banking, payments, and fintech); life sciences, medical devices, and pharmaceuticals; transportation and travel; technology and telecommunications; retail and ecommerce; asset management and private equity; and sports, media, and entertainment. Notably, in private practice, he has defended clients in GDPR enforcement actions involving artificial intelligence and machine-learning (AI/ML) technologies in an EU member state.
As the ICO’s former head of Legal (Regulatory Enforcement) and a member of its legal leadership team, Vishnu helped drive certain of the ICO’s key investigations and enforcement actions involving the GDPR, the Privacy and Electronic Communications Regulations (PECR), and cybersecurity. Vishnu’s experiences, including with multi-regulator enforcement actions via the UK Digital Regulatory Cooperation Forum (DRCF), which brings together the ICO, CMA, OfCom, and FCA, and as a liaison with government and law enforcement agencies such as the UK NCSC and NCA, inform his practice.
He is regularly invited to speak at industry and academic conferences and provides commentary to the media about privacy, cybersecurity, AI/ML, and other technology regulatory law issues. Prior to joining the ICO, Vishnu practiced (including as a partner) for more than a decade at leading law firms in London, New York, and Dublin, where he focused on technology, data privacy, and cybersecurity law as well as intellectual property transactional matters.
