As you know our VPN service support L2TP/IPSEC as well.
Here, I want to introduce this protocol for my customers in brief,Hope it'll be useful :
IPsec (Internet Protocol Security) is a security protocol that provides encryption and authentication over the Internet.
IPSec supports network-level data integrity, data confidentiality, data origin authentication, and replay protection.
Because IPSec is integrated at the Internet layer (layer 3), it provides security for almost all protocols in the TCP/IP suite, and because IPSec is applied transparently to applications, there is no need to configure separate security for each application that uses TCP/IP.
IPSec helps provide defense-in-depth against:
• Network-based attacks from untrusted computers, attacks that can result in the denial-of-service of applications, services, or the network
• Data corruption
• Data theft
• User-credential theft
• Administrative control of servers, other computers, and the network.You can use IPSec to defend against network-based attacks through a combination of host-based IPSec packet filtering and the enforcement of trusted communications.
Cisco has been a leader in proposing IPsec as a standard (or combination of standards and technologies) and has included support for it in its network routers.
Thank you
