Juniper last week extended its lineup of hardware platforms for SSL VPNs, rolling out new devices for corporations looking to secure networked resources.

The Secure Access 700, 2000, 4000 and 6000 appliances run Juniper's Instant Virtual Extranet (IVE) software, which uses SSL encryption to secure data communications on remote connections, an extranet or an intranet.

SSL is available on standard Web browsers, so rather than installing and maintaining a full VPN client on each user's device, Juniper can use the existing browser or lightweight software, says Niv Hanigal, product manager for the Secure Access line. That software can be downloaded and updated on the fly, over the network, he says. This makes SSL VPNs a less-expensive alternative to traditional IPSec VPNs, he adds.

The product line is designed for secure access to enterprise resources by employees in the main office or remote locations, as well as by business partners needing access to certain kinds of data. It lets administrators allow access only to certain kinds of resources based on who is using the VPN and from where, Hanigal says. For example, when using a corporate wireless LAN, an employee might have access to different kinds of information than when using the wired LAN, he says.

Juniper adds the new products to a lineup that includes Secure Access 1000, 3000 and 5000 for larger companies and the Remote Access 500 for small and midsize businesses. Those platforms were introduced in 2001 by Neoteris, which was later acquired by NetScreen. NetScreen was acquired by Juniper last year.

The SA 6000 is the corporate workhorse of the new lineup, with an SSL acceleration chipset that can encrypt traffic using the Rivest Cipher 4, Triple-DES and Advanced Encryption Standard protocols as well as compressing it, Hanigal says. The SA 6000 also has dual redundant hot-swappable hard drives that mirror data in real time to allow for smooth recovery in case of a failure. The SA 6000 can be used by as many as 2,500 clients at the same time, and as many as eight of the devices can be clustered together to support more than 10,000 concurrent users, Hanigal says.
