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.
For more information on what’s changed, why it’s important, and details on the global rollout schedule, FAQs, communication methods, and more, please visit the /17 Global Implementation Documentation page.

Microsoft OneDrive and SharePoint DLP (NRT) Migration to Graph APIs
for CASB
As a follow-up to our initial communication, this is a reminder that we have begun the batch-wise migration of all existing Microsoft OneDrive and SharePoint DLP (Near Real-Time) instances to the new Skyhigh Splash NRT pipeline for Graph delta API integrations.
Timeline & Mandatory Action: Microsoft has announced the official deprecation of the SharePoint Add-In framework on April 2, 2026. To avoid any further disruption in DLP monitoring, it is essential to migrate your environment to the new Graph delta API framework ahead of the date.
Why this is critical:
- Support Cut-off: After April 2nd, the SharePoint Add-In Apps will no longer be supported by Microsoft.
- Security Risk: Skyhigh will be unable to provide Near Real-Time (NRT) DLP support for your OneDrive and SharePoint integrations if the migration to the Delta API is not completed.
- Deadline: You are required to confirm your migration window no later than March 2, 2026.
Next Steps: A representative of the Skyhigh team should have already reached out to you. You can also proactively contact your Skyhigh Representative or Skyhigh Support to get your migration scheduled immediately.
Completing the migration early will give your team sufficient time to validate the environment and ensure a seamless transition. Skyhigh encourages you to act promptly to safeguard your security posture. If your migration schedule has already been finalized, please disregard this notification. Documentation: For more details on the migration process and FAQs, see OneDrive and SharePoint Migration Documentation.
