No access for cybercriminals: CCB launches ‘Closed Business Day’

On 5 October, the day after ‘Open Business Day’, the Centre for Cybersecurity Belgium is calling for organisations and businesses to close their doors once again. Not to the general public, but to cybercriminals. ‘Closed Business Day’ draws extra attention to online security for businesses. And that is essential. ⇨ (UNDER EMBARGO until Monday 5 octobre 7:00)

Artificial Intelligence (AI) enables cyberattacks that were previously unthinkable. AI models detect vulnerabilities at breakneck speed and use them to try to gain access to companies’ systems.

Director-General of the Centre for Cybersecurity Belgium
