Which protocol is used by NSX-T to facilitate secure communications?

NSX-T uses IPsec to facilitate secure communications, particularly for site-to-site connections and secure tunnel formation. IPsec (Internet Protocol Security) is a suite of protocols that establishes a secure communication channel by encrypting data packets exchanged over IP networks. It provides confidentiality, integrity, and authentication, making it suitable for securing communications in a virtualized environment like NSX-T.

Utilizing IPsec enhances the security posture of the virtual networking infrastructure by ensuring that data is protected while traversing potentially untrusted networks. This is especially important for multitenancy environments where isolation and security across virtual networks are paramount. IPsec can be used in conjunction with various tunneling protocols, further enhancing its capabilities in establishing secure and reliable communications.

Other protocols mentioned, such as SSL, are also used in different contexts within NSX-T for securing data flows, but IPsec is specifically geared towards creating secure network layer communications between sites, which is essential for NSX-T deployment scenarios.
