Adtech

Adtech encompasses technology, privacy, advertising and competition issues. We guide our clients through this, offering pragmatic advice routed in our understanding of the technology.

 

The last few years have seen both significant technological change and also ever increasing regulatory scrutiny.

Our clients are both users and providers of advertising technology. They are publishers implementing a new consent management tool, advertisers looking to enhance their use of first party data and technology providers launching new data driven products and responding to regulatory enquiries.

With one of the most highly-regarded data protection practices in the world, together with our market-leading technology and advertising practices, adtech - which incorporates aspects of all three areas - sits at the very centre of Bristows’ expertise.

As a result, we can guide our clients through all the issues affecting their adtech projects, including getting to grips with the latest technological developments and innovations to help them achieve their goals in a compliant manner. Our work includes advising on data protection and competition related regulatory enforcement, commercial contracting, advertising regulation and brand safety issues.

The depth of our expertise in the Adtech sector is matched by its breadth. We have specialists across all our practice groups, so we can support you whatever your legal requirements.
