Zero trust network access (ZTNA) is a security model that assumes no trust is given to users or devices inside or outside the network. ZTNA verifies every access request and grants access only to the specific resources that the user needs. This helps to reduce the risk of data breaches and other security threats.
ZTNA is becoming increasingly important as businesses move to the cloud and adopt a more distributed workforce. Traditional security models, which rely on firewalls and VPNs, are no longer effective in protecting these new environments. ZTNA provides a more flexible and scalable security solution that can be adapted to the specific needs of each business.
