What is a VPN?
A virtual private networks (VPN) gives you anonymity and privacy when using the internet by hiding your internet protocol (IP) address, and securing and encrypting your connections and activity. People often describe a VPN as a secret tunnel between a device and the internet; when using a VPN, nobody can see what the user is doing inside the tunnel except themselves and the person on the other end that they're communicating with. With a VPN, users can send and receive information via unsecured or public networks as securely as if they were directly connected to a private network.
What features should I look for in a VPN?
The strongest enterprise VPNs offer a mobile app as well as client software for PCs, so they they can support an organization's entire device fleet. It's important that this app is kept up-to-date so that it performs efficiently and doesn't leave your organization vulnerable to web-based threats.
A VPN should also be flexible and support multiple server locations, to help speed up connections no matter where your users are connecting from, as well as multiple protocols, so that you can choose the one that best meets your organization's need.
Enterprise VPNs should also have central management functionality so that admins can easily manage user access permissions, set up and remove accounts, and see which devics are currently using the VPN.
Finally, it's important that an enterprise VPN has a kill switch. This cuts off a device's network access in the event of an IP leak due to the VPN being overloaded or a failed connection, preventing unencrypted data from being transferred and stopping the user's IP address from being leaked.
