Description: Endpoint authentication is the process of verifying the identity of users or devices accessing endpoint resources. This process is fundamental in the context of cybersecurity, especially in environments adopting the Zero Trust model. In a Zero Trust environment, it is assumed that no entity, whether internal or external, is trustworthy by default. Therefore, every access attempt to resources must be rigorously authenticated and authorized. Endpoint authentication involves evaluating several factors, such as user identity, device integrity, and access request context. This may include credential verification, device configuration assessment, and access location checks. Endpoint authentication not only protects critical organizational resources but also helps prevent unauthorized access and cyberattacks. As remote work and the use of personal devices become increasingly common, endpoint authentication is an essential tool for ensuring information security and business continuity.
