It's Not Too Late To Ditch Your VPN: Why ZPA Is The Superior Secure Access Solution - Part 1
zscaler, April 29,2025
This is the first of the blog series examining the advantages of Zscaler Private Access (ZPA) architecture. In this post, we'll focus specifically on how ZPA addresses the security limitations of traditional Virtual Private Network (VPN) solutions, which have become increasingly inadequate for securing enterprises.
Encrypted VPN technology was invented over 30 years ago to help organizations provide remote users access to applications hosted on internal networks. While this model worked for decades, its inherent architectural flaws have made it a liability in today's threat landscape.
VPNs are fundamentally built on a castle-and-moat security model, where everything inside the network is treated as trusted and secure. Unfortunately, attackers have learned to exploit inherent VPN vulnerabilities, making the technology an urgent security risk for modern businesses.
