VPNs exist to provide convenient security that can serve a smaller-scale need or purpose. Here are some examples of VPNs:
Cloud VPN: VPNs can be deployed on top of virtual machines in order to “cloud-enable” them. This takes the hardware capability of a VPN and (artificially) adds cloud functionality, such as greater scalability and endpoint protection. While these may be more useful for extended enterprises than a typical standalone VPN appliance, they may still lack the flexibility to support a remote or hybrid workforce at scale.
Personal/Mobile VPN: Companies such as ExpressVPN and NordVPN offer downloadable VPN apps so users can keep data secure on their personal devices. This is a good measure to have in place if you’re browsing the web on insecure Wi-Fi networks. Some free VPNs are available to help keep your devices secure, but they’ll later become paid.
Remote access VPN: These VPNs are designed specifically for users working from outside of the office in a corporate setting. They’re typically deployed within a company’s data center but can be extended (at the cost of web and/or app performance) to protect remote users from malware and other threats. These became extremely common after the onset of the COVID-19 pandemic. Read more.
