Following the news that Michel Barnier, the chief negotiator on Brexit at the European Commission, has stated that a joint response to security threats will be a key part of the future relationship, cybersecurity expert commented below to highlight the cybersecurity issues because of Brexit.
Unhindered and unimpeded cybercrime data exchange is indeed crucial both for the UK and EU. Most governmental agencies may require a crystal-clear legal framework to proceed after Brexit, especially when the information involves legally-protected data or cases of criminal prosecution.
However, given the essential role British law enforcement agencies play in the continental fight with cybercrime, I am pretty confident a solution will emerge in a timely manner. In any case, private parties and cybersecurity companies will likely have a safe harbor to cooperate even before formal agreements are inked.
