Introduction to Virtual Private Networks (VPN) provide an easy, affordable, and secure
Virtual Private means for businesses to conduct operations and provide network
Networks connectivity to all offices and partners. Using 3Com's intuitive Web
interface, a secure connection may be established between two or more
sites.
Data that is intended for delivery to a remotely connected site is
automatically encrypted using the VPN's accelerated cryptographic
processor. The data is delivered via the Web and decrypted at the
intended destination.
The SuperStack 3 Firewall VPN implementation uses the IPSec VPN
standard. This guarantees compliance with other VPN products, such as
3Com PathBuilder 400 and Check Point Firewall-1 that adhere to the
same standard.
