Symantec Endpoint Protection

Symantec Endpoint Protection (SEP) is a client-server solution that ensures the protection of your endpoint devices from malicious attacks and threats.

This document contains the best practices required in Symantec Endpoint Protection and Netskope Client to ensure smooth interoperability.

Environment

This document was created using the following components:

  • Symantec Client Version: 14.0.MP1 build 2332 (14.0.2332.0100)

  • Netskope Client version: 92.1.0.943

  • OS: Windows 2016 Server Datacenter

Certain configurations in Symantec Endpoint Protection and Netskope tenant web UI can ensure that the processes or traffic from either of the applications are not blocked and directed to the Netskope Cloud.

Configurations In Symantec Endpoint Protection Manager

The Symantec Endpoint Protection includes a default firewall policy that contains a default set of rules. The firewall rules are the baseline that determines whether to allow or block the incoming and outgoing packets through the firewall.

To allow the Netskope Client to operate seamlessly, add a new firewall rule while creating a firewall policy in Symantec Endpoint Protection Manager and add the following executable files:

  • stAgentSvc.exe

  • StAgentUI.exe

  • nsdiag.exe

To add a new firewall rule:

  1. Login to Symantec Endpoint Protection Manager.

  2. Go to Policies > Firewall .

  3. Open a Firewall Policy and click Rules depending on the Windows or mac settings.

  4. On the Rules tab, click Add Rule.

  5. On the Add Firewall Rule Wizard window, enter the rule name.

  6. Click Next after you complete each action.

  7. From the Select the Action for the Rule section, select Allow Connections.

  8. From the Select the Rule Applications section, select Only the applications listed below and enter the following .exe files:

    • stAgentSvc.exe

    • StAgentUI.exe

    • nsdiag.exe

  9. Fill out the options on each dialog box, and then select Submit.

You can view the newly created rule in Firewall Policy > Rules > Firewall Rules. To confirm that Netskope Client is not blocked, go to the endpoint machine and perform Update the Policy from the SEP manager.

Important

Select the checkbox in the Enabled column for the rule(s) on the Rules page.

Configurations In Netskope Client

Add exceptions (Certificate Pinned Application exception type) on the Netskope tenant WebUI to allow the SEP traffic to bypass Netskope and reach its destination. You must add exceptions to the Netskope Steering Configuration. To learn more, view Exceptions.
