What’s the difference between VPN and ZTNA?
Network-level access vs application-level access: VPNs permit full private network access to any user with valid login keys. Zero Trust Network Access restricts user access to specific applications, limiting the data exposure and lateral movement of threats in case of any cyberattack.
Deep visibility into user activity: VPNs lack application-level controls and have no visibility to the user actions once he's inside the private network. ZTNAs log every user action and provide deeper visibility and monitoring into the user behavior and risks to enforce informed, data-centric controls for securing sensitive content within applications. The logs can be fed to SIEM tools for real-time and centralized visibility into user activity and threats. ZTNAs can further be integrated with endpoint security solution to allow adaptive access based on continuous assessment of device security posture.
