SSL Remote Access VPNs: Is this the end of IPSec?

Remote Access VPNs, like every other modern technology are continually evolving and improving. Initially nothing more than a server connected to a modem into which remote users dialed, to gain access to a limited number of company resources, they now use broadband connections to allow customers, suppliers, vendors and mobile users access to a vast array of resources from Extranets to Intranets and even classified information. Until recently IPSec based VPNs were the industry standard on which most companies relied as they provided the reliability and security required to protect sensitive company information. While IPSec continues to be the generally regarded standard for site to site VPNs, SSL remote access VPNs have recently been introduced and are quickly gaining in popularity prompting many to believe that IPSec remote access VPNs are on their way out. This paper looks at the two VPN technologies with respect to remote access, discusses the advantages and disadvantages of each and whether they can co-exist.
