VPNs: What Do They Do, and What Don't They Do?
Virtual Private Networks, or VPNs, are not exactly a new technology.

Recently, as workforces continue to decentralize due to the rise of Cloud Computing as well as the current pandemic, VPN has become an even hotter topic and is being marketed as a critical security solution.
