A new Zscaler ThreatLabz report reveals that while organizations have improved their mean time to detect threats, they're struggling with what happens after an alert is triggered. The report highlights that AI-powered attacks have dramatically shortened the window for human response, with VPNs becoming a critical vulnerability as attackers exploit remote access infrastructure to move laterally through networks at unprecedented speeds. The gap between detection and effective response is emerging as the new frontier in cybersecurity defense.
