Proton Sentinel is available to Proton Unlimited, Family, and Business account holders. It offers an additional layer of security and privacy for users, especially those who may be targeted by cybercriminals due to their high-profile status, such as human rights activists and journalists.
The program uses AI to detect potentially suspicious activities on user accounts. It also includes a human element, involving expert security analysts who work alongside the automated security protection system to quickly identify any signs of infiltration or account takeover attempts.
