IPsecis anend-to-end encryption protocol suitethat operates at thenetwork layer, providingauthentication, integrity, and confidentialitybetween virtual networks—even across different cloud environments like Azure and AWS.

NIST SP 800-77 Rev. 1 (Guide to IPsec VPNs):

“IPsec provides network-layer protection through authentication headers (AH) and encapsulating security payloads (ESP), suitable for securing traffic across untrusted environments.”

FTP is insecure, and SSH is more suitable for command-line access or remote sessions—not secure VPC-to-VPC tunnels.
