Technology that provides secure access to applications based on identity and context, replacing traditional VPNs.
Zero Trust Network Access (ZTNA) applies Zero Trust principles to network access. Instead of connecting users to entire networks (like VPN), ZTNA grants access to specific applications based on user identity, device posture, and context. Users only see and access the applications they're authorised for—the network itself is invisible. This reduces the attack surface dramatically compared to VPN, where a compromised user can explore the entire network. ZTNA is delivered through cloud services or on-premise gateways and is replacing VPN for many organisations.
Why It Matters
The DSC Perspective:
VPNs give too much access—a compromised account can reach anything on the network. ZTNA limits access to specific applications, containing potential breaches. It also provides better user experience than traditional VPN.
