Is Delinea Down?

## Incident Overview On October 20, 2026, customers using the Inventory service in the US region were unable to add or update Inventory data due to an unhealthy infrastructure node. During this period, the Inventory application and read operations remained fully available; however, new Inventory data was not processed until the issue was resolved. * **Start:** October 20, 2026, 09:32 UTC * **End:** October 20, 2026, 15:54 UTC  ## Root Cause and Remediation The underlying compute resource hosting our infrastructure node in the US region became unhealthy, causing data writes to stop while read operations continued to function normally. Diagnostics also identified elevated CPU pressure on other nodes within the same cluster during the incident window, suggesting broader resource strain. Because existing data remained accessible and the Inventory application continued to operate, the write failure was not detected by our automated monitoring and was instead identified by our internal team approximately five hours after impact began. Once the unhealthy resource was identified, our team restored it to a healthy state, and the ability to add and update Inventory data was restored shortly afterward. ## Preventative Actions * Implement alerting on Inventory data update activity to detect sustained drops in new data. * Enhance infrastructure health monitoring to automatically detect and remediate unhealthy nodes before they affect service operations.  We sincerely apologize for the disruption this caused and the inconvenience to your operations. We are committed to preventing recurrence through the above actions. --- [2026-10-21T12:03:14.446-04:00] (resolved) We’re pleased to inform you that the incident affecting the Inventory service has been resolved. Our team has implemented a fix, and all systems are now operating normally. We apologize for any inconvenience this incident may have caused, and we appreciate your understanding and support. For any questions or concerns, please reach out to our support team at https://support.delinea.com. --- [2026-10-21T10:48:40.821-04:00] (investigating) We are investigating an issue affecting Inventory Service in the US region which is impacting the ability to add or make updates to Inventory. Core platform functionality remains operational. We are working to restore full functionality as soon as possible.

## Incident Overview  Customers using SAML-based single sign-on \(SSO\) to access Delinea Platform and Secret Server Cloud experienced login failures. Affected users were presented with a block page when attempting to sign in, while users with existing sessions were unaffected. The issue impacted customers across the US, EU, UK, CA, SEA, and UAE regions.  * **Start**: October 13, 2026, 12:46 UTC * **End**: October 13, 2026, 15:22 UTC  ## Root Cause and Remediation  The issue was caused by a new security rule introduced by our web application firewall \(WAF\) provider. The rule was intended to be released in a non-blocking monitoring mode for evaluation but was instead activated in enforcement mode. As a result, it incorrectly identified legitimate SAML authentication requests as unauthorized and blocked them before they reached our services. No changes to Delinea’s application or infrastructure contributed to this issue.  Because the requests were blocked at the WAF layer, our monitoring did not detect the issue before the first customer reports were received. Once the issue was identified, our team applied exception rules for the affected authentication paths, restoring login functionality at 15:22 UTC.  Our WAF provider subsequently identified the affected rule, deployed a corrected configuration globally, and confirmed through post-deployment validation that legitimate traffic was processing normally.  ## Preventative Actions  * Enhance anomaly-based alerting for WAF blocks targeting authentication endpoints to detect abnormal traffic patterns. * Our WAF provider is also strengthening its validation, approval, and monitoring controls for future security rule deployments.  We sincerely apologize for the disruption this caused and the inconvenience to your operations. We are committed to preventing recurrence through the above actions. --- [2026-10-13T12:56:10.275-04:00] (resolved) This incident has been resolved. --- [2026-10-13T12:02:10.943-04:00] (monitoring) We are continuing to monitor for any further issues. --- [2026-10-13T11:50:43.127-04:00] (monitoring) We are continuing to monitor for any further issues. --- [2026-10-13T11:49:12.869-04:00] (monitoring) A fix has been implemented and we are monitoring the results. --- [2026-10-13T11:44:04.783-04:00] (identified) The issue has been identified and a fix is being implemented. --- [2026-10-13T12:55:34.525-04:00] (investigating) Starting approximately 12:32 UTC on October 13, 2026, some users signing in to the Delinea Platform with SAML single sign-on (SSO) were unable to complete login and received an "Access Denied – Error 15" message after authenticating with their identity provider. Users who were already signed in, and users signing in without SAML SSO, were not affected. The issue was caused by a security rule at a third-party edge network provider that incorrectly blocked SAML login responses. Our engineering team applied a configuration change at 14:11 UTC and SAML SSO logins have been succeeding normally since.

We apologize for the inconvenience this has caused and appreciate your patience as we worked to restore normal service.
