On the surface, if your VPN disconnects it shouldn’t be a big deal. But, as always, it’s not that simple.
You use a VPN for privacy, and if it crashes, you may be exposed suddenly to your ISP, without any warning. Depending on what you were doing when the VPN disconnected, you may have some questions to answer to the ISP (or to the authorities). Your protected information may have just gotten a lot more vulnerable without the anonymity of the VPN. There’s a chance you don’t even know that your VPN crashed and that your activities are now in full view of prying eyes. If it happens when you are torrenting, you may attract some very unwelcome attention from your ISP. If it happens while you are sharing files or personal information, you may catch the attention of identity thieves, or worse.
Some VPN tools to control disconnections
Luckily, most VPNs have protections in place for this unplanned occurrence. One of these is the kill switch, which is automatically triggered when the VPN disconnects. In other words, it will kill your Internet connection when the VPN crashes. The job of this tool is that you don’t leak your real IP while the VPN is not working.
The Wi-Fi protection is another tool that was designed to avoid exposure caused by a disconnection of the VPN. This feature will establish a VPN connection the minute your mobile finds an unreliable Wi-Fi network. This is a very effective, hassle-free way to protect your information when your device connects to a public Wi-Fi hotspot. This tool used to be rare on most VPNs, but many providers are including it on their software because of the growing dangers of public Wi-Fi.
A VPN disconnection sounds like a simple thing without serious consequences. With some luck, you just have to turn back on. But, in some cases, you leak your identity and online activity, and the damage is irreversible. To avoid such situation, tools like a kill switch should be mandatory.
