RESOLVED 5 days ago - at 01/16/2026 03:10PM

Services are stable and operating normally.

We identified an internal service issue that prevented customer traffic from being diverted to Imperva’s mitigation network during active attack conditions. The issue was caused by an internal authentication failure. The service was restored after the affected component was restarted, and traffic diversion is now functioning as expected. We are performing a detailed root cause analysis and enhancing monitoring and automated recovery mechanisms to ensure faster detection and prevent recurrence. Additional details will be shared once the investigation is complete.
