Network Security vs Zero Trust Network Access: Complete Comparison

Network security and Zero Trust Network Access (ZTNA) are two distinct approaches to protecting an organization's network and data. While network security focuses on perimeter-based defense, ZTNA takes a more holistic approach, verifying the identity and permissions of users and devices before granting access to resources. Companies like Google, Microsoft, and Amazon Web Services (AWS) have already adopted ZTNA, as seen in their implementation of Google Cloud's BeyondCorp and Microsoft's Azure Active Directory (Azure AD), which utilizes the expertise of security experts like Bruce Schneier and Andrew Ng.
