Global PoP Maintenance: IP Network Address Space Expansion
for Secure Web Gateway - Required Update
2025 - 2026 Rolling updates
As part of the initiative to enhance network performance, scalability, and long-term service reliability, we have transitioned to a new IP address range for all Skyhigh Security Points of Presence (PoPs) and selected services. To avoid further disruption in service, we ask that all SSE Cloud Web Gateway customers review and update Firewall Allow Lists and IPSec/GRE Tunnel IP Addresses.

Upcoming Web DLP Policy refresh to Enable New DLP Capabilities
For DLP
Oct- Nov 2025
We are writing to inform you about an upcoming backend Web DLP policy update scheduled between [29-10-2025] and [07-11-2025]. This update is automatic and requires no action on your part. You will see an entry in the audit log once the activity is complete.
This refresh is designed to introduce new Web DLP capabilities and optimizations. A key enhancement is the activation of the new Default Bypass List for DLP Policies. This feature will help reduce false positives in Web DLP processing by allowing you to exclude specific telemetry sources, such as Google Analytics, from DLP policy enforcement.
This is Phase 2 of our refresh. While Phase 1 focused on active Web DLP users, this phase will update the policies for all Skyhigh Web customers. If you are an active Web DLP user, you can disregard this message as your policy was updated in Phase 1.
If you have any questions, please contact your account representative or our support team.
