KnowBe4 Outage History

On Thursday, July 16, 2026, from approximately 19:57 to 21:12 \(UTC\), some customers experienced difficulty logging in to the Defend console, seeing a **Find Out More** screen instead of console access. This issue was caused by a synchronization issue between Salesforce and our internal licensing systems, which incorrectly set some customer license counts to zero. As a result, affected customers were unable to log in. To resolve this issue, our team applied a temporary license override to restore access for affected customers while correcting the underlying licensing records in Salesforce. Once corrected, the systems automatically synchronized the accurate values, and the Defend console access returned to normal performance by approximately 21:12 \(UTC\). To prevent this type of issue in the future, we are implementing improvements to the Salesforce synchronization process to ensure accurate license counts. No data loss occurred as a result of this issue.

From Tuesday, June 23, 2026, at approximately 10:03 \(UTC\) to Thursday, June 25, 2026, at approximately 11:54 \(UTC\), some US and EU customers experienced intermittent 502 errors when logging in to KCM GRC. This issue was caused by network traffic attempting to connect to invalid multilevel subdomains, which overwhelmed the cache serving KCM GRC and resulted in login errors. Our team initially updated the configuration of our content delivery network, which temporarily resolved the errors, but they returned later that day. After further investigation, we identified the caching issue as the root cause and deployed an infrastructure-level fix to prevent multi-level subdomain traffic from affecting the cache. KCM GRC returned to normal performance by 11:54 \(UTC\) on June 25, 2026. To prevent this type of issue in the future, we are evaluating additional protections to guard against similar traffic that could affect the cache. No data loss occurred as a result of this issue.

From Tuesday, June 16, 2026, at approximately 17:34 \(UTC\), to Thursday, June 18, 2026, at approximately 22:41 \(UTC\), some customers experienced intermittent unavailability of the **Phishing Security Test Reports** page in the KnowBe4 console. This issue was caused by a code change that introduced a conflict between two methods for processing phishing campaign data. As a result, phishing campaigns still using legacy phishing categories were unable to load the **Phishing Security Test Reports** page. To resolve this issue, we updated the code to process campaigns correctly under both classification systems, and the **Phishing Security Test Reports** page returned to normal performance by June 18, 2026, at 22:41 \(UTC\). No data loss occurred as a result of this issue.

From Wednesday, June 17, 2026, at approximately 19:00 \(UTC\), to Thursday, June 18, 2026, at approximately 18:20 \(UTC\), some customers were unable to view results in the KnowBe4 Security Center’s Human Risk Management widget. ‌ This issue was caused by a recent infrastructure migration that left an internal service connection pointing to an outdated endpoint. Though the underlying data processing was unaffected, the Human Risk Management widget could not retrieve data or display results. To resolve this issue, our team updated and reapplied the connection configuration, and the KnowBe4 Security Center returned to normal performance by approximately 18:20 \(UTC\) on June 18, 2026. To prevent this type of issue in the future, we are improving our migration process to ensure that all endpoints are valid after a migration. We are also strengthening known-good rollback procedures in cases where a migration cannot be completed as planned. No data loss occurred as a result of this issue.

On Monday, June 15, 2026, from approximately 15:30 to 16:34 \(UTC\), some customers experienced processing delays with phishing and training campaigns in the KnowBe4 console. This issue was caused by an update that introduced an incompatible software version. This software prevented our background processing service from completing queued tasks. As a result, training enrollments, notification sending, and SmartGgroup enrollments were delayed. To resolve this issue, our team deployed a fix that reverted the affected dependency and restored normal job processing. Once the fix was deployed, the affected queues cleared, and the KnowBe4 console returned to normal performance by 16:34 \(UTC\). To prevent this issue in the future, we have implemented additional testing layers for similar deployments. No data loss occurred as a result of this issue.

On Wednesday, June 3, 2026, from approximately 14:49 to 16:09 \(UTC\), customers experienced errors when accessing the **User Details** page in the KSAT console. This issue was caused by an update that introduced missing fields, which prevented the **User Details** page from loading. To resolve this issue, our team updated the console again to restore the missing fields, and the KSAT console returned to normal performance by approximately 16:09 \(UTC\). To prevent similar issues in the future, additional automated tests were added. No data loss occurred as a result of this issue.

On Thursday, May 28, 2026, from approximately 18:07 to 18:57 \(UTC\), some customers experienced issues uploading custom content to the new ModStore in KnowBe4 Security Awareness Training \(KSAT\). This issue was caused by an update to the new ModStore that disabled the language selection field in the “Add Translation” upload step, preventing customers from completing that required part of the upload process. To resolve this issue, our engineering team identified the recent deployment responsible for the defect, corrected it, and deployed the update to production. KSAT returned to normal performance by 18:57 \(UTC\). To prevent this type of issue in the future, we are improving test coverage for the affected upload flow and adding automated checks to catch similar issues before they reach production. No data loss occurred as a result of this issue.

On Wednesday, May 27, 2026, from approximately 09:22 to 15:24 \(UTC\), some UK customers experienced intermittent issues with outbound email delivery in Protect. This issue was caused by a configuration change that disrupted outbound email processing. Affected emails failed to send and were instead held in a delivery queue. To resolve this issue, our team temporarily rerouted traffic while investigating the root cause and then updated the affected configuration. After the configuration was updated, all queued messages were delivered, and Protect returned to normal performance by 15:24 \(UTC\). To prevent this type of issue in the future, we are integrating the configuration update into future deployments. We are also improving monitoring to detect similar disruptions more quickly. No data loss occurred as a result of this issue.
