Zero Trust VPN Alternative: Why Traditional VPNs Fall Short
Traditional VPNs leave gaps attackers exploit. Learn how a Zero Trust VPN alternative prevents credential theft, lateral movement, and full compromise.| Portnox
The need for secure remote access continues to grow as organizations expand support for hybrid work, cloud adoption, and modern applications. For years, virtual private networks (VPNs) and early Zero Trust Network Access (ZTNA 1.0) models provided a foundation for remote connectivity. Yet both approaches introduced gaps that have become more apparent as threats advance… The post ZTNA 2.0: The Next Stage of Secure Remote Access appeared first on Portnox.| Portnox
