Benefits
The following are bene?¬?ts of Cisco Easy VPN:
?– Centrally stored con?¬?gurations allow dynamic con?¬?guration of end-user policy and
require less manual con?¬?guration.

allows the provider to change equipment and network con?¬?gurations as needed, with
little or no recon?¬?guration of the end-user equipment.
?– Cisco Easy VPN provides centralized security policy management.
?– Cisco Easy VPN enables large-scale deployments with rapid user provisioning.
?– Cisco Easy VPN removes the need for end users to install and con?¬?gure Cisco Easy
VPN Remote software on their PCs.
