In Zscaler Zero Trust Exchange, which service is most comparable to a Web Application Firewall (WAF)?

In the context of Zscaler's Zero Trust Exchange, the service that is most comparable to a Web Application Firewall (WAF) is Private App Protection. This service provides the necessary features to secure web applications from various threats, similar to how a WAF operates.

Private App Protection focuses on securing applications that are deployed within an organization's private network and ensuring that only authorized users and devices can access them. It accomplishes this by incorporating security measures that protect against threats like unauthorized access, data breaches, and application-layer attacks, which are typical concerns addressed by traditional Web Application Firewalls.

By monitoring and controlling access to applications, Private App Protection ensures that application traffic is scrutinized, allowing organizations to enforce security policies and compliance requirements. This functionality mirrors the role of a WAF, which specifically protects web-facing applications from exploitation.

The other services mentioned do not fulfill the same roles as a WAF. For instance, the Internet Gateway primarily serves as a secure channel for accessing the internet; Firewall Security provides perimeter protection; and Data Loss Prevention focuses on preventing the unauthorized transmission of sensitive information. None of these aim to protect web applications in the way that Private App Protection does.
