This article details the communication ports, protocols and processes used by Symantec Endpoint Protection (SEP) clients and the Symantec Endpoint Protection Manager (SEPM), versions 11.0, 12.0 and 12.1.


Communications Ports and Protocols

Port Number Port Type Initiated By Listening Process Description
8014 / 80 TCP SEP clients httpd.exe (Apache)
svchost.exe (IIS)
Communication between the SEPM and SEP clients and Enforcers.
(8014 in MR3 and later builds, 80 in older).
SEP 12.x uses Apache. SEP 11.x uses IIS.
443 TCP SEP clients svchost.exe (IIS)
httpd.exe (Apache)
Optional secured HTTPS communication between a SEPM and SEP clients and Enforcers.
1100 TCP AjaxSwing httpd.exe (Apache) Tells AjaxSwing on which port to run RMI Registry. (SEP 12.1.x)
1433 TCP SEPM sqlserver.exe Communication between a SEPM and a Microsoft SQL Database Server if they reside on separate computers.
1812 UDP Enforcer 12.x: httpd.exe (Apache)
11.x: w3wp.exe
RADIUS communication between a SEPM and Enforcers for authenticating unique ID information with the Enforcer.
2638 TCP SEPM 12.1.x: dbsrv11.exe
11.x: dbsrv9.exe
Communication between the embedded database and the SEPM.
2967 TCP SEP clients Smc.exe The Group Update Provider (GUP) proxy functionality of SEP client listens on this port.
8765 / 8005 TCP SEPM SemSvc.exe This is the Tomcat Shutdown port.
In SEP 12.x, port 8765 is used.
In SEP 11.x, the SEPM listens on the Tomcat default port of 8005, except for RU7, which uses 8765. 
8045 TCP SEPM SemSvc.exe In SEP 11 RU6, SEPM, the registry is started by the Tomcat servlet container. CreamTec's AjaxSwing uses the existing registry to communicate with its client agents that run in stand alone mode
8443 TCP Remote Java or
Web Console
SemSvc.exe HTTPS communication between a remote management console and the SEPM. All login information and administrative communication takes place using this secure port.
8444 TCP Symantec Protection Center (SPC) 2.x SemSvc.exe This is the SEPM web services port. SPC 2.x makes Data Feed and Workflow requests to SEPM over this port.
8445 TCP Reporting Console httpd.exe (Apache) Added in SEP 12.1.x. HTTPS reporting console.
8447 TCP Process Launcher semlaunchsrv.exe Added in SEP 12.1.5. Only at localhost's request, this service virtual account launches processes that require higher privileges so that other SEPM services do not require them.
9090 TCP Remote Web Console SemSvc.exe Initial HTTP communication between a remote management console and the SEPM (to display the login screen only).
39999 UDP Enforcer SNAC.exe (Windows SNAC)
CClientCtl.exe (Windows ODC)
Communication between the SEP clients and the Enforcer. This port is used for authentication of clients by the Enforcer.

  • SEP 12.1 - The SEPM uses the Apache web server on the ports seen in the table above.
  • SEP 11 - The SEPM uses two web servers: Internet Information Services (IIS) and Tomcat (Apache Tomcat). IIS uses port 80 (or 8014) and 443; Tomcat uses port 9090 and 8443. The communication between IIS and Tomcat use the HTTP protocol. IIS uses port 9090 to talk to Tomcat, and Tomcat uses port 80 to talk to IIS.

Client-Server Communication

For IIS, SEP uses HTTP or HTTPS between the clients or Enforcers and the server. For the client server communication it uses port 8014 (or 80) and 443 by default. In addition, the Enforcers use RADIUS to communicate in real-time with the manager console for client authentication. This communication is done on UDP port 1812.

Push deployment

Management servers and clients use TCP 139 and 445, UDP 137 and 138, and TCP ephemeral ports for push deployment. As of SEP 12.1.5, TCP 22 is used for push deployment of Mac clients.

Remote Console

  • 9090 - used by the remote console to download .jar files and display the help pages.
  • 8443 - used by the remote console to communicate with SEPM and the Replication Partners to replicate data.
  • 8444 - used by the SPC 2.x remote console to make Data Feed and Workflow requests.
  • 8445 - used by SEPM for reporting data, and returns report data to SPC 2.x over this port.

Client-Enforcer Authentication

The clients communicate with the Enforcer using a proprietary communication protocol. This communication uses a challenge-response to authenticate the clients. The default port for this is UDP 39,999.
