GRE is well-suited for encapsulating multiple types of transport layer protocols over IP networks. It allows for the wrapping of packets from various protocols to be transmitted over an IP infrastructure but does not inherently provide any encryption or authentication, distinguishing it from protocols like IPSec. IPSec, while also used for VPNs, provides robust encryption and authentication, making it a more secure option where confidentiality and data integrity are necessary. SSL/TLS primarily secures data transmissions between networked devices rather than encapsulating multiple protocols for transit. MPLS is generally used for high-performance telecommunications networks to direct and carry data from one network node to the next.
