VPNs are not Bullet Proof
June 24, 2021
Virtual Private Networks (VPN) are a good thing. They protect unauthorized access to your data by transmitting information through an encrypted tunnel. Your privacy is also protected by masking your real IP address and therefore your location. With these privacy and security measures, it still doesn’t mean that all VPNs are created equal. Your information could still be exposed if you misconfigure the VPN, the encryption is weak, or some other vulnerability is exposed.
VPNs can also leak your IP address, which means your real IP is exposed. Free VPNs are more prone to this leakage, which is why we never recommend using a free VPN service. It’s fairly simple to check if your VPN is exposing your real address. TechViral has a recent post with instructions for testing whether your VPN has a problem properly masking your IP address. Even if you don’t use a free VPN service, you should periodically test your VPN to make sure your privacy is still being protected.
