Zero-Trust Network Access (ZTNA)

• Zero-Trust Network Access (ZTNA)

  • Zero-Trust Network Access (ZTNA) is an access model that verifies user and device context before granting access to specific applications.
  • ZTNA is an alternative to VPN because it typically provides application-level access instead of broad network-level access.

  • Key idea

    • Apply least-privilege access per app or service.
    • Continuously evaluate identity, device posture, and policy.
    • Reduce exposed attack surface compared with full-tunnel remote access.
