About the Security Cloud

F-Secure Security Cloud is a cloud-based threat analysis system that maintains a security rating for common programs, files and websites.

When an F-Secure security product encounters a suspect program or file, it sends a query over the Internet to the Security Cloud and checks for the latest rating available for the program (that is, whether it has already been rated as 'safe' or 'harmful'). Based on the rating, the security product may then either quarantine the suspect file, block it or allow it to proceed.
