• • Analyze rule order, policy dependencies, bypasses, exclusions, and catch-all behavior to safely integrate new requirements into existing production configurations.

• • Develop and execute phased implementation, testing, rollback, and validation plans for Zscaler changes that may affect user access or production traffic.

• • Troubleshoot Zscaler service issues involving Client Connector, authentication, traffic forwarding, application access, policy enforcement, certificates, SSL inspection, and integrations.

• • Align Zscaler deployments with the CISA Zero Trust Maturity Model and organizational Zero Trust strategies.

• Integration with Enterprise Tools:

• • Integrate Zscaler with endpoint security, vulnerability management, infrastructure monitoring, identity, SIEM/SOAR, and ITSM platforms, including CrowdStrike, Tripwire, Qualys, ScienceLogic, Splunk, ServiceNow/HEAT, Active Directory, and Microsoft Entra ID, as applicable.

• • Implement Zscaler integration with cloud storage and collaboration platforms to enforce secure data access and sharing.

• Security Strategy & Consulting:

• • Document and address organization's information security, cybersecurity architecture, and systems security engineering requirements throughout the acquisition life cycle

• • Participate in security reviews, identify gaps in security architecture, and develop a security risk management plan

• • Advise stakeholders on best practices for security modernization, cloud migration, and risk reduction.
