F-Secure 25.5

[harlan4096]

Version 25.5

​Released June 2025

VPN support for ARM64​

VPN functionality has been added for ARM64 systems. Some features, such as VPN bypass and OpenVPN, are not yet supported.
 
Other improvements​

• When Device Protection updates are over 7 days old, all automatic protections of Device Protection are disabled (and cannot be enabled by the user). This is a new Microsoft requirement, allowing Windows Defender to take over system protection. After the successful installation of a new update, the protections will be automatically enabled again.
  

Bug fixes​

• Resolved an issue where exclusions for network (UNC) paths did not work.
  
• Addressed crashes of UnifiedSDK.Service.exe on certain systems.
  
• Fixed a crash (BSOD) occurring on specific systems (fix originally released in version 25.4 MR1).
  
• Improved browser extension detection in Chromium-based browsers.
  
• Made the "Suspicious page modification" detection less sensitive.
  
• Fixed an issue where VPN was greyed out and stuck on Loading… state.
  
• Fixed an issue where VPN prevented access to internal network after sleep.
