Firewall Settings for DSPM-Hosted Instances

Overview

Because the DSPM (also known as Netskope One DSPM) application is hosted and managed by Netskope (instead of being self-hosted), you may need to update your firewall/security group settings in order for Netskope DSPM to connect to your Data Stores.

Important Egress Requirements: The specific firewall configurations you need depend on your deployment use case:

– For Direct Connections (no sidecar): Apply the rules in the DSPM Application Egress section.
– For Single Appliance Deployments: Apply the rules in the DSPM Application Egress, Sidecar Egress and Ports, and DLP Service Egress sections. All three apply to the same host.
– For Distributed Deployments (separate sidecars + DLP appliance): Apply the rules in the Sidecar Egress and Ports and DLP Service Egress sections to their respective hosts.

DSPM Application Egress

All Data Store scans will originate from these IP addresses, so you need to whitelist them:

This list has been updated to include new public CIDR blocks from Netskope’s AWS accounts. If you use whitelisting, please add these new ranges to ensure uninterrupted connectivity.

Sidecar Egress and Ports

If you are using sidecars to connect with your Data Stores, you may need to update your firewall/security group settings in order to provide outbound egress for sidecars to communicate with DSPM.

Additionally, in the distributed deployment model, the sidecar must be able to communicate with the DLP appliance via HTTPS (port 443). In the Single Appliance model, this communication happens locally on the same host.

For more information, please visit any of our sidecar installation articles in the Netskope DSPM Deployment Guides.

DLP Service Egress

The DLP appliance requires its own outbound egress to the internet. This connectivity is necessary for the appliance to validate its license and download configurations.
