Zero Trust is applied not only to users, but to devices and applications – whether on-premises, remote, or in the cloud – and assumes no device or person can be trusted. The problem with these legacy approaches is that VPNs enable remote and unprotected user devices to connect to the network, and a bad actor who gets their hands on leaked credentials can easily break in and launch an attack via spyware or ransomware.īy contrast, Zero Trust looks at the user’s role and location, the device being used and the information they’re requesting, and assumes the user is guilty until proven innocent.Įach user, machine, and application has its own perimeter security, and access is controlled based on users having “just-enough” and “just-in-time” access according to their identity, role, and company policy. The approach is a paradigm shift from older perimeter-based network architectures that rely on approved IP addresses, ports and protocols to establish access controls and validate trusted entities, where anyone connecting over a VPN is considered trusted. Never trust, always verifyĪ Zero Trust architecture guards against unauthorized access by enforcing access policies based on the context of the device or user attempting access. In this post, we’ll explain the concept of ZTNA, how it works, and why device recognition technology is the basis of a zero-trust architecture.

In their mission to combat the growing threat of cybercrime, Cybersecurity solution providers are helping customers implement the zero-trust model, to provide stronger cyber threat defense and a better end-user customer experience. But in the world of IT, it characterizes a new cybersecurity strategy that’s gaining a lot of traction among enterprises: Zero Trust Network Access (ZTNA). “Trust no one.” This quote calls to mind multiple action thriller blockbusters that featured star-powered casts and a renegade fugitive running for his life.
