Which component supports the required communication to send audit logs from Privilege Cloud through the...

CyberArk’s Privilege Cloud documentation for SIEM integration (Syslog) states that to connect to SIEM in Privilege Cloud, you must first deploy the Secure Tunnel.

That means the Secure Tunnel is the required component that enables the communication path for sending Privilege Cloud audit logs via Syslog (TCP/TLS) to your SIEM.

Why the other options are not correct for this Privilege Cloud Syslog requirement:

A (CyberArk Syslog Writer) is typically referenced in CyberArk Identity / ISP logging contexts, not as the required Privilege Cloud SIEM transport component. (Privilege Cloud SIEM doc calls out Secure Tunnel explicitly.)

C (Privilege Cloud Connector) is not what the SIEM/Syslog doc identifies as the required prerequisite; it specifically calls out Secure Tunnel.

D (CyberArk Identity Connector) is used to integrate directory services (AD/LDAP) with CyberArk Identity/Identity Administration, not as the Privilege Cloud Syslog transport prerequisite.
