In this concise yet powerful 6-minute video, we break down the evolution of cybersecurity from traditional VPNs to modern Zero Trust Architecture (ZTA). Learn why VPNs once the go-to solution for remote access are no longer sufficient in today’s threat landscape, and how Zero Trust is reshaping digital defense.
We compare the trust models, access controls, and security postures of VPNs vs. Zero Trust Network Access (ZTNA), highlighting real-world use cases and vulnerabilities. The video also features insights from CISA’s Zero Trust Maturity Model and NIST which define the principles and implementation strategies for Zero Trust in both public and private sectors.
