The 7020SRG includes support for high performance IPSec. IPSec ensures the protection of sensitive information between participating IPsec devices. IPsec is a framework of open standards, developed by the IETF, that provides security for the transmission of sensitive information over unprotected network by encrypting the data. IPSec acts at the network layer, protecting and authenticating IP packets between participating IPSec devices. 7020SRG IPSec is optimized for site to site VPNs, for example to a POP or a backup datacenter location, with support for AES-256 and SHA-256 secure public key encryption.
