Bristows is ready to help with any data breaches, large or small. We can call on many years of experience, assisting clients in connection with many of the world’s largest breaches. We can assist with the immediate response and containment of a security incident, notifying authorities, as well the longer-term impact, including any follow-on litigation. With security breach reporting laws strengthening around the world, getting the right legal advice is an essential part of any breach response plan.

Breach reporting laws in the UK, EU, and around the world mean it is essential to have good, reliable and pragmatic legal advice as soon as you think you might have suffered a data breach. Bristows can help you identify your legal obligations, prioritise the most important, and begin taking steps to reduce your overall exposure.

Bristows has a wealth of experience advising multinational and UK companies on data breaches, including some of the most high profile cyber security incidents in recent years. Working with our international network, we help with reporting obligations around the world, as well as public statements and communications to affected individuals.

Effective data breach management is not limited to the immediate response. Bristows has extensive experience with ICO investigations and other supervisory authorities around the world. We can also assist with civil claims from affected individuals, clients or business partners.  

Longer term, we can also help with ongoing risk management, including identifying and implementing remedial measures, as well as embedding incident reporting and breach management within your wider compliance processes.
