What is a VPN?
A VPN, or Virtual Private Network, allows you to create a secure connection over the public Internet. It establishes an encrypted tunnel through your service provider’s network and channels all of your traffic through the service provider. This effectively hides your origin; your traffic is indistinguishable from the service provider’s.
The VPN’s goal is to keep data secure and to anonymize your Internet traffic. Its effectiveness as a solution depends on the type and sophistication of the encryption method that the VPN service provider uses; the VPN service provider’s internal security protocols, including VPN server security; and the ability of the VPN service to provide adequate speed and performance at peak usage times.
What VPN solutions do not have built in which creates a significant weakness is multifactor authentication (MFA)
For stronger security, see MobiKEY, which has multifactor authentication built in.
