Boost security and productivity
Web Content Control enables administrators to restrict Internet usage and manage what web content users are allowed to access from the company network, thus avoiding clear risks of typically malicious content.

  • Individual site whitelisting, for example to internal sites, are possible, overriding standard enforced categories
Safe online business transactions

  • Improved security through controlled and safe access to business-critical assets
  • Protects the web browser, the weakest link in business-critical sessions
  • Administrators can allow connections only to sites that are verified as safe by F-Secure when banking online or performing other sensitive actions, to make sure employees can work safely

F-Secure Dataguard
F-Secure DataGuard subjects selected high-risk and value-critical folders to advanced monitoring and additional detection logic. It makes them significantly more fortified against ransomware, and prevents malicious and unknown applications from destroying or tampering with the data that they contain. The high-risk and value-critical folders include, for example, the Downloads folder (web downloads), document folders, temp files (email attachments), and data repositories.

The feature's complementary detection logic significantly increases detection accuracy and aggressiveness against ransomware and their encryption processes. The Data Access module ensures that the data in these folders is not destroyed, tampered with, or encrypted by malicious or unknown applications, such as ransomware. Among other benefits, the Data Access module enables the recovery of data in the event of a successful ransomware attack, as it cannot encrypt the data located in those folders.
