Zero Trust Network Access (ZTNA) is a security model that requires strict verification for every user, device, and application attempting to access resources, regardless of their location within or outside the network. Unlike traditional security models that trust internal network traffic, ZTNA operates on the principle of never trust, always verify—meaning every access request is treated as potentially malicious until proven otherwise. ZTNA typically involves multi-factor authentication (MFA), least privilege access, and continuous monitoring of user and device behavior. By enforcing strict access controls and ensuring that only authenticated users and devices can interact with specific resources, ZTNA helps mitigate risks from insider threats, compromised credentials, and lateral movement within the network. Popular ZTNA solutions include Zscaler, Cisco Duo, Palo Alto Networks Prisma Access, and Akamai. ZTNA is particularly beneficial for organizations supporting remote work or operating in hybrid cloud environments. Learn more: https://en.wikipedia.org/wiki/ZTNA
