Endpoint Protection Small Business Edition (Cloud)


Attention Customers of Symantec Endpoint Protection Small Business Edition (SEP SBE) and Symantec Endpoint Protection Cloud (SEP Cloud)

These products will be discontinued on November 2, 2020. On this date, the product will stop protecting the endpoints, and access to the console no longer will be available. We recommend that customers migrate to Symantec Endpoint Security Enterprise.

For more information, see Transitioning to Symantec Endpoint Security Enterprise Guide.

Users cannot access printers or shared drives and files when Symantec Endpoint Protection Small Business Edition (SEP SBE) cloud is installed on the network.


By default, file and printer sharing are disabled when using Symantec Endpoint Protection Small Business Edition (SEP SBE).

To enable file and printer sharing, first create a copy of the default policy, make your configuration changes, and then apply the new policy to a group. See Enabling file and printer sharing for more information.

Advanced configuration settings

Certain environments require additional firewall rules to gain clear communication to network devices and file shares. These environments usually consist of more than one subnet, or have shared network devices connected directly to workstations.

In these environments, create a new firewall rule with the following ports opened locally for both inbound and outbound traffic.

  • TCP 135
  • UDP 137
  • UDP 138
  • TCP 139
  • TCP 445
  • UDP 5355

When connectivity issues persist

If users in the group continue experiencing connectivity issues to network devices and shares, follow these steps within the policy assigned to the affected group.

  1. Under Network Protection, check Report Blocked Events.
  2. Test the connection several times.
    After a short period of time (sometimes up to 30 minutes), any blocked events will appear in the History tab for the affected computer.
  3. In the report, in the Category column, look for Firewall Activities.
  4. In the Activity column, click the link for the firewall activity.
  5. Review which local ports and protocols are being blocked, and add them to the firewall rule you created earlier.
  6. Under Program Control, create allow rules and add any executable files recommended by the manufacturer of the shared network device.
