Our Verdict

Bitdefender VPN

F-Secure VPN

F-Secure VPN is better than Bitdefender VPN for most uses. F-Secure provides significantly better security and higher speeds overall, with greater tunnel integrity to prevent IP and DNS leaks alongside a functional kill switch. By contrast, Bitdefender struggles with IP leaks and an unreliable kill switch that can leave your data largely exposed. Bitdefender does offer much better protection against man-in-the-middle attacks; however, this is a notable weak point for F-Secure due to its TLS interruption risks. Both VPNs have notably predatory policies that allow for the collection and distribution of user data.
