Issue Report - 19.6 F-Secure Internet Security - Banking Protection - Breaks VPN\Internet

Karibu

• F-Secure Internet Security v19.6 > Banking Protection
• Windows 11 23H2
• Mullvad VPN
  
  I can reproduce this issue at-will every single time on any website that activates F-Secure Internet Security > Banking Protection:
  
  1. System is configured to always connect to internet via Mullvad VPN network interface (this VPN must be used per security policy; may not\can not disable VPN).
  
  2. Navigate to any website that activates Banking Protection.
  
  3. Banking Protection blocks Mullvad VPN and thereby breaks network interconnectivity completely.
  
  Because Banking Protection blocks the VPN and thereby breaks all network connectivity, I must disable Banking Protection completely before performing any financial transactions - which defeats the entire purpose of using the F-Secure product in the first place. This is the only workaround available on my end. I cannot disable the VPN nor may I or do I have the capability to alter the system network configuration in any way per security policy.
  
  I have FSDIAG and I also ran Debug Logs (I need to know where the Debug Log is located so I can submit it via Private Message; I also need to review it for sensitive data prior to submission).

Hi,
I'm not an expert, but have you tried adding your VPN app, or even the entire folder, to F-Secure exclusion list? I've done this a few times on my PC (not Mullvad app), and it's worked for me.

Hi @Karibu

Is there any way for you to change the tunnel protocol from Wireguard to OpenVPN to see if that helps, or is that under an admins control and cannot be changed ? (#1 security policy)

Mullvad is one of my favorite VPN's, but it is also the one that gets flagged the most, especially by Google's CAPTCHA's as well at one time by my bank, including getting the email verification, "is that really you"? To help with that, I connect to the nearest Mullvad VPN server location to me and use their OpenVPN protocol which does seem to help quite things down in general. The login from F-Secure's Password Vault went through.

Otherwise, as was posted above, is to add Mullvad into F-Secure Exclusions, and just have the Banking Protection protect you.
