Avishai Ostrin

Head of Privacy and Data Protection

Ever since his first Technology & Law course at university, Avishai has been passionate about the relationship and tension between the law and new and emerging technologies, and how individuals’ rights are protected in the modern digital age. It is within this context that he has developed a particular expertise in data protection and privacy law.

Avishai was born in the US, moved to Vienna and then to London, and from London he moved to Israel with his family in 1992, where they settled in Jerusalem. He completed his legal studies at the Interdisciplinary Centre in Herzliya (IDC), where he received an LL.B., as well as a B.A. in Government, Diplomacy and Strategy.

Dual-qualified in England & Wales and Israel, Avishai trained and qualified first as an Israeli lawyer, with a focus on corporate and commercial law, at one of Israel’s top tier law firms. There he represented corporates from all around the globe, ranging from two-founder upstarts to large multinational conglomerates. Avishai advised on complex high-tech mergers and acquisitions, private equity and venture capital investments, as well as corporate finance transactions. One of his clients was Israel’s largest private equity firm. This experience gave him invaluable insights into the inner workings of some of the largest brand names in the world.

Upon joining Asserson in 2016, Avishai used the knowledge and experience he had amassed to build the firm’s privacy and data protection practice. He qualified as an English solicitor, and within a short period has emerged as one of Israel’s top specialists on European data protection and privacy laws and regulations.

Avishai currently advises some of Israel’s top tech players on all areas of data protection and privacy – planning, building and executing privacy programmes, conducting internal audits, and reporting to boards of directors on various matters relating to data and privacy. He has particular expertise in advising on, and handling, investigations, audits and various other types of interactions between companies and the European data protection authorities, in particular the UK’s ICO. Avishai also regularly advises on complex multi-jurisdictional data transfer arrangements. He is a retained adviser on data and privacy issues for one of the UK’s largest consulting firms, and many companies draw on his unparalleled expertise to navigate the complex web of data protection regulation in the UK, and across Europe generally.

Avishai is uniquely positioned to draw on his experience advising tech companies based in the “Start-Up Nation” on issues relating to privacy and data protection in their European operations. He is also certified by the International Association of Privacy Professionals (IAPP) as an specialist in European privacy law (CIPP/E).

Avishai is a die-hard New York Jets (American Football) fan, and enjoys a variety of music genres – from classical to opera, and classic rock to heavy metal. He religiously attends spinning classes, and on the weekends enjoys going to the beach with his wife, three children, and dog, Brownie.
