Patrick wants to deploy a virtual private networking (VPN) technology that is as easy for end users to use as possible. What type of VPN should he deploy?

A TLS-based VPN (often called an SSL-based VPN, despite SSL being outmoded) provides the easiest way for users to use VPN since it does not require a client. SSL VPNs also work only for specific applications rather than making a system appear as though it is fully on a remote network. HTML5 is not a VPN technology, but some VPN portals may be built using HTML5. Security Assertion Markup Language (SAML) is not a VPN technology. IPSec VPNs require a client or configuration and are thus harder for end users to use in most cases.
