Cyderes Outage History

On May 12, 2026, we identified and resolved a platform processing issue that impacted portions of incident generation workflows. Following restoration activities, we identified a separate third-party service issue that resulted in additional intermittent processing delays. Mitigation actions were implemented and service stability has been restored. Platform monitoring and analyst investigation capabilities remained operational throughout the affected periods, though some customers may have experienced delayed incident processing. We will continue to monitor the environment closely and review both events to further strengthen resiliency and recovery processes. We appreciate our clients’ patience and understanding while these issues were being addressed.

Cyderes has developed custom parser configuration changes and have restored impacted detection coverage. These changes have been deployed and have been under evaluation for over 24 hours with no further issues identified. For this resolved matter, if you have any questions, please contact your Client Success Manager.

Cyderes is observing performance improvement in Microsoft Log Analytics, however, delays and access issues will persist until all systems have recovered. Cyderes clients may continue to experience degraded services in Security and Operational Health Alerting. We will continue to provide updates as recovery progresses.

Microsoft has reported the Log Analytics issue as resolved. Cyderes is actively processing backlogged alerts. Clients may experience delayed Security and Operational Health Alerts. Updates will continue as services fully recover.

Microsoft is experiencing a widespread Microsoft 365 outage that is affecting access to Microsoft Defender portals and related security services. Defender EDR is functioning on endpoints, Cyderes is receiving alerts via our connectors, but the cloud portals and backend services are intermittently unavailable or degraded. This issue impacts management, visibility, and portal access currently – not the agents on endpoints. Cyderes will continue to monitor the situation closely. MSFT ref.

The vendor has addressed the underlying problem and continues to monitor the situation.

Due to a widespread Internet outage affecting multiple third-party vendors, case notification and ticket management systems experienced delays. However, the SOC has been able to triage and investigate security alerts. During the period of the outage, clients were contacted manually in the case of a confirmed security incident. Services are gradually coming back online across various vendors.

We are continuing to monitor for any further issues.

All notification services are now operational. We are continuing to monitor and appreciate your patience.

All major subsystems are now operational. We appreciate your patience during the recent service interruption. We'd also like to provide an update on two related items within the Cyderes Portal: Case View Sorting: Table sorting in the case view is currently limited to the default "Newest to Oldest" order. Our team is actively working to restore full sorting functionality. Case List Pagination: A change has been implemented for case list navigation. Instead of traditional page-to-page navigation, you will now see a "Load More" prompt at the bottom of the list. We will notify you once the case view sorting is fully restored. Thank you for your continued partnership.
