SANS ISC has just published an in-depth article on Virtual Private Network (VPN) pros/cons and how to select best protective options.

In more generic terms, VPNs offer a more secure and private way to use the internet. VPNs do deliver on some of these claims. But I think they also over promise. think it does not make much sense to talk about security without a clear threat in mind that you are defending against. On the other hand, even without a VPN you may be in pretty good shape. With 80+ % of websites using HTTPS, and browsers/operating systems implementing DNS over HTTPS, you pretty much already have all the protection a VPN would give you. Do your homework, search recent news for VPN providers who leaked data (or didn’t encrypt traffic at all).
