A new report from Zscaler ThreatLabz highlights how artificial intelligence has dramatically shortened the time defenders have to respond to cyber threats, with VPNs now becoming a primary entry point for attackers. The research shows that AI has collapsed the traditional human response window, allowing cybercriminals to move through networks at unprecedented speeds once they gain remote access. Organizations are being urged to rethink their VPN security strategies as these tools increasingly become the fastest path to a successful breach.
