The primary distinguishing feature between IPSec and SSL is their respective OSI reference model protocol communication tier levels. IPSec operates at the network layer of the OSI reference model while SSL operates at the transport layer. Protection mechanism utilization should be determined by information sensitivity. IPSec or SSL can be combined with a VPN to limit data interception, manipulation, and redirection. Standards exist for encryption systems, such as SSL and IPSec, which ensure compatibility among various hardware and software platforms. Comparatively, regarding trans-border privacy issues, SSL VPN can be considered a viable alternative to stand-alone IPSec deployment.
