A new generation of remote access software has emerged that combines the two main competing virtual private networking technologies.
The result adds extra security to remote working through Secure Sockets Layer encryption and support for a broad range of applications through traditional IPSec technology.
Talisen Technologies is one supplier that has developed the hybrid software. Its Talisen Gateway 4.3 gives companies access to complex web applications such as Microsoft Windows Sharepoint, Lotus Domino and UGS Teamcenter, said the firm.
The product works by giving external users of the local area network a proxied version of the application rather than the application itself.
All external access is routed through a single point of entry - an SSL-encrypting web gateway - to minimise the security risk to the corporate Lan, said Talisen.
Microsoft Windows Sharepoint support is an important feature, because of Sharepoint's complexity, said the firm.
George Brill, president of Talisen, said, "Software clients and additional administration are required for the remote users, and IPSec VPN connections may directly tunnel into the enterprise Lan. Proxy-based solutions can address these issues. However, complex applications such as Sharepoint can be very difficult to proxy at an enterprise level," he said.
