Acronym for Zero Trust Network Access—secure application access without traditional VPN.
ZTNA stands for Zero Trust Network Access. See 'Zero Trust Network Access' for the full definition. ZTNA is a core component of SASE (Secure Access Service Edge) architectures and is increasingly replacing VPN for remote access.
Why It Matters
The DSC Perspective:
ZTNA is the modern approach to remote access. It's more secure than VPN and often provides better performance. Consider ZTNA when reviewing remote access strategy or responding to VPN-related security questions.
