Zero Trust Network Access (ZTNA) is an approach to cyber security that provides users with secure access to applications and data within a network. It works by verifying every request that a user attempts to make before granting them access, as well as continuously monitoring user behavior for any suspicious activity. This makes it nearly impossible for hackers to gain unauthorized access, as each request is reviewed in real-time. ZTNA is used by organizations looking for greater protection against malicious attacks. By deploying this technology, they can ensure their sensitive data remains safe while providing customers with a more secure online experience.
