News - SSL VPN | |
10 reasons why SSL VPNs are revolutionising the way we work1. Clientless deployment: SSL VPNs make sense because they adapt widely deployed Internet and e-commerce technologies such as Web browsers and their built-in SSL (secure sockets layer) encryption and digital certificates that give remote workers VPN-type connectivity to the workplace. Standard IPSec-based VPNs require users to download and configure special IPSec clients onto their PCs, which can be complex and time-consuming.
2. Security: SSL VPNs provide security on multiple levels. User data streams are encrypted using 128-bit SSL encryption, the same technology that protects millions of daily ecommerce transactions. 3. Simplicity for users: Anyone who can use a Web browser can easily reach their business applications using an SSL VPN. They simply log into a special URL, type their username and password, and are presented with their authorized applications just as if they were in the office. 4. Rapid deployment: Most SSL VPNs can be activated in less then a day – often in just an hour or two. There’s no need to reconfigure application servers or other elements of the network infrastructure, nor to distribute client software to remote users. 5. Promoting a flexible work environment: Organizations are deploying SSL VPNs to meet their employee requirements for flexibility. 6. Fast response to emergencies: A recent Gartner report recommended that their clients look into VPN technologies as a means of allowing employees to work from home in the event of an emergency. 7. Lowered total costs of ownership: The simplicity of SSL VPNs leads to dramatically lower help desk costs, since there is no need to install, configure and maintain PC clients on users’ remote PCs. As a result, Netilla estimates that SSL VPNs are up to 40 percent less expensive than IPSec-based VPNs in terms of total cost of ownership over a multi-year period. 8. Ability to access any application: Recent SSL VPNs from vendors such as Netilla can now provide secure remote access to virtually any enterprise application – including client/server applications (in Windows, UNIX, Linux, AS/400, Citrix or mainframe environments) as well as Web applications. 9. Application-layer proxy design: Many SSL VPNs use an application-layer proxy design that acts as a secure buffer between incoming user requests on the public Internet and back-end application servers, which protects network infrastructure. The SSL VPN appliance terminates user requests, authenticates them and enforces policy, then forwards them onto the appropriate application server. 10. Future-proof design: SSL VPNs are fundamentally open technologies, as they employ standard Web browsers, SSL encryption and standard interfaces (although products from various vendors can be highly differentiated). As such, they are well positioned to support new technologies such as wireless and PDA access. IPSec VPN implementations, in contrast, typically include more proprietary technologies that can pose compatibility problems. by Linda Joynes – European Marketing Director for Netilla Networks Inc | |
