The development of virtual private networks (VPNs) was motivated by the need to reduce the cost of secure communications by leveraging ubiquitous Internet access. While many organizations have used IPSec VPNs to meet these objectives for site-to-site networking, they have not achieved the same degree of success when deploying remote access VPNs. Simply put, IPSec remote access often proves harder to manage and costlier to implement than the investment appears to return. The requirements for secure access can't be set aside; enterprises must provide connectivity to a growing mobile workforce more cost-effectively, and this mandate is now complemented by additional requirements to comply with existing and pending financial and healthcare privacy legislation. But the drivers that necessitate rapid adoption of secure access have led organizations to consider alternatives based on the Secure Sockets Layer (SSL).
