What is Zero Trust Network Access (ZTNA)?

Zero Trust Network Access (ZTNA) is a security framework based on the principle of 'never trust, always verify.' It provides secure access to applications and resources based on defined policies, regardless of the user's location or device. ZTNA solutions commonly verify user identity and device posture before granting access, and continuously monitor and validate access throughout the session. This helps to reduce the attack surface and prevent unauthorized access to sensitive data and applications.
