Things get more complicated when companies decide to run closed tunnels for better defense against that last example. 'That can and does happen and is a reason why we still need anti-malware defenses. 'I think the biggest problems are related to malware that is on an endpoint device and that is using a split tunnel to send information outside of the VPN,' Girard said. And VPNs that use obsolete encryption that’s easy to break are obviously unsafe. VPNs with simple static passwords that are used for everyone and never changed also pose a security loophole. Girard said he has seen VPNs incorrectly set up where a certification validation failure causes the encryption to be removed. There are, however, no simple answers when it comes to VPN security. I need virtual privacy, and I get that from TLS without requiring a layer three bridge onto a LAN somewhere.' The more we move to using cloud apps, it is very much the case that I really do not need to be on a network. 'But clearly, when I use a web app, I am connecting to an app, not necessarily to a full network with all of the capabilities (and risks) that network connectivity entails,” Girard said. 'Think about that. It also means mobile VPNs can be as good as any other VPN implementation. GartnerĪnd, as long as privacy is protected by a strong, industry-approved encryption algorithm – as Proton's is – 'that’s as good as it gets,' according to John Girard, vice president and distinguished analyst in Gartner's Endpoint and Mobile Security practice.

Instead, the free VPN service is supported by paid plans. The company claims to be the only VPN with no bandwidth limits, data caps or 'privacy invading ads.' Proton also claims to not install adware on a device or sell user data to third parties – it has a strict no-logs policy. ProtonMail, an end-to-end encrypted email service born out of the European Organization for Nuclear Research (CERN) in 2014, is sold by Proton Technologies AG. 'Enterprises are deploying micro-VPN or per-app VPN capabilities to protect sensitive data on corporate apps without having to tunnel/encrypt all data, which is cumbersome and affects performance,' Hochmuth added. VPN functions are being built into mobile security products such as Symantec's mobile endpoint protection, which invoke on-the-fly VPNs to protect users when threats are detected on open wireless connections, Hochmuth said.
