Explanation

SSTP (Secure Socket Tunneling Protocol) is a Microsoft-developed VPN protocol that tunnels traffic over HTTPS on port 443, purpose-built for individual client devices connecting to a remote corporate network - the defining characteristic of a Remote Access VPN. L2TP is a general-purpose tunneling protocol that lacks native encryption and is more commonly associated with site-to-site deployments (as L2TP/IPsec); it is not exclusively a remote access solution. MPLS VPN is a service-provider technology that connects multiple sites (offices, data centers) at the network layer - it has no client component and is strictly a site-to-site technology. GRE over IPsec encapsulates routing traffic between two network endpoints, making it a site-to-site tunnel, not a remote client protocol.

Memory tip: "SSTP uses SSL over port 443 - the same port as HTTPS - so it's built for individual remote users who need to punch through firewalls, just like a browser does."
