VPNmanager
Avaya VPNmanager is an optional Avaya application that lets network managers define, configure and manage VPNs from any location. Large networks would want to use VPNmanager to do distributed managed firewall rules as well as VPN management across the network.
Security
The SG203 and SG208 security gateway employs cryptographic algorithms and keys powerful enough for the most sensitive business communications to provide data stream privacy. It supports DES and Triple DES, and AES encryption, as well as the ISAKMP key management standard.
