IPSec transport mode provides protection primarily for upper-layer protocols, as it only encrypts the payload (data) of the IP packet and leaves the header unencrypted. This means that the original IP header is still visible and can be used for routing, but the upper-layer protocols (such as TCP, UDP, or ICMP) are protected by encryption. IPSec tunnel mode, on the other hand, encrypts the entire IP packet (header and payload), providing protection for the entire packet and all the layers.
