Description: Zero Trust Network Access (ZTNA) is a security model that redefines how access to applications and services is granted, especially in cloud environments. Unlike traditional approaches that relied on perimeter security, ZTNA is based on the premise that no entity, whether internal or external, should be trusted until its identity and context are verified. This means that access is granted in a granular manner, considering factors such as user identity, location, device, and behavior. This approach allows organizations to protect their critical resources by limiting access only to those users and devices that meet specific security criteria. ZTNA is particularly relevant in a world where remote work and the use of cloud applications are increasingly common, as it provides an additional layer of security that adapts to the dynamic needs of modern businesses. By implementing ZTNA, organizations can reduce the risk of security breaches and ensure that only authorized users have access to sensitive information, regardless of their physical location.
