What is the primary benefit of using a Custom Zscaler Connector for SaaS Application?

In Zscaler’s SaaS Security and Data Protection services, a Custom Zscaler Connector (for example, for Google Workspace, Microsoft 365, or Salesforce) is designed so that Zscaler can connect to a specific SaaS tenant using only the minimum set of required credentials and scopes. The documentation for onboarding custom connectors explicitly emphasizes that, instead of providing full administrator rights, you authorize narrowly scoped API/OAuth permissions that allow Zscaler to scan data at rest and enforce security controls while adhering to least-privilege principles.

This minimal-credential approach reduces risk if the connector credentials are ever compromised, simplifies compliance audits, and aligns with modern security best practices. Zscaler needs just enough access to read, classify, and (where applicable) remediate or quarantine sensitive content in sanctioned SaaS applications, not broad tenant-wide admin access. Options suggesting temporary credentials, broad cross-tenant access, or full administrator rights contradict this design philosophy and the way the connectors are documented. Therefore, the primary benefit—and the key phrase you should associate with Custom Zscaler Connectors for the exam—is that they enable Zscaler to operate using a minimum set of required credentials for each SaaS Application tenant.
