What is the TCP port used for CyberArk's proprietary protocol or VPN?

The TCP port utilized for CyberArk's proprietary protocol or VPN is TCP 1858. This port is specifically designated for communication between CyberArk components, ensuring secure data transfer and proper functionality of its security features. By assigning a unique port for its proprietary protocol, CyberArk can manage traffic effectively, thereby enhancing the overall security posture of the system.

The other options do not serve this specific purpose within the CyberArk infrastructure. TCP 8080 is commonly used for HTTP traffic, while TCP 443 is standard for HTTPS communications, which are unrelated to CyberArk’s proprietary protocol. TCP 3306 is typically associated with MySQL database connections and does not pertain to CyberArk's communication needs.
