What would make an IPSec VPN so secure?

Web Protocol Safety IPSec IETF defines an open-standard stability framework framework, that may be used by each parties while in the IP layer to be sure the confidentiality, integrity and replay resistance of IP details messages transmitted in excess of the network by the use of encryption, integrity verification, data source authentication, and so on. The main application of IPSec may be the development of a digital personal network (VPN); remote branches of enterprises can use IPSec VPN to ascertain a safe transmission channel to accessibility the corporate headquarters community.
