• Granular Access Control: ZTNA grants access based on a user's unique identity, device,
location, and the specific application or resource they need. This minimizes the attack surface
and reduces the potential for lateral movement within the network if a breach occurs. Even if a
hacker gains access to a user's credentials, they would be limited to the specific resource they
were authorized for.
• Seamless Cloud Integration: ZTNA integrates seamlessly with cloud-based applications,
eliminating the need for complex network configurations and point-to-point connections. This
simplifies IT management and reduces the overall attack surface. Users can access authorized
cloud resources directly without needing to access the corporate network first.
• Simplified User Experience: ZTNA eliminates the need for cumbersome VPN connections.
Users can access authorized resources directly with minimal friction, improving productivity and
overall user experience.

The Road to Zero Trust: Challenges and Considerations
While ZTNA offers significant benefits, implementing a zero-trust architecture requires careful planning
and integration with existing security tools. Here are some key considerations:

• Planning and Integration: A successful ZTNA deployment requires careful planning and
integration with existing identity management and access control systems. This ensures a smooth
user experience and minimizes disruption during the transition.
• User Training: Educating users on ZTNA and proper security practices is crucial for its success.
Users need to understand the importance of strong passwords.
