What is Port 8200?
Port 8200 is the default port for HashiCorp Vault, an enterprise secrets management and encryption-as-a-service platform. Vault clients and applications use this port to authenticate, retrieve secrets, and request dynamic credentials. This is one of the most security-sensitive ports in a modern cloud infrastructure and must be tightly access-controlled.

Security Considerations
Port 8200 (HashiCorp Vault) is classified as critical risk. This port should not be exposed to the public internet. The service transmits data without encryption, making it vulnerable to eavesdropping, credential theft, and man-in-the-middle attacks.
Recommendation: Block this port at the firewall. Use encrypted alternatives (SSH, SFTP, HTTPS) instead.
