Jun 1, 2026

June 2026 (panther-analysis) delivered strengthened security monitoring capabilities and cleaned signal processing to improve incident response. Key features delivered include Okta Security Monitoring Enhancements with new queries and rules for actor activity, legacy API authentication without MFA, and service app management scopes, plus standardization of 90-day baselines for Okta authentication events to enable more reliable trend analysis. AWS Root Activity Detection Enhancements refined detection to prioritize resource-modifying actions while excluding read-only events, and included dedup tuning to reduce noise. No major bugs fixed this month; maintenance focused on stability and data quality. Impact: improved threat visibility, faster triage, and more consistent baselines across Okta and AWS signals, supporting proactive risk reduction and compliant monitoring.
