Frequently asked questions
How long does a Zscaler deployment take?
Zscaler is cloud-delivered and markets subscription setup in minutes, but full enterprise rollout takes longer: T-Mobile deployed the Zero Trust Exchange within its operations in about 3 months. Plan a phased migration off VPNs and legacy proxies rather than a switch-flip cutover.
Is Zscaler pricing published?
No. Zscaler sells quote-based annual subscriptions. The Essentials Platform and the recommended Zscaler Platform bundle cover internet access, private access and data security, with many advanced modules, standalone products and sized packages priced separately. Expect a demo and sizing exercise before you see numbers.
Can Zscaler secure employee use of AI tools?
Yes. GenAI Security finds shadow AI and enables safe use of public GenAI apps, controls risky Microsoft Copilot oversharing, and the DSPM and AI-SPM capabilities cover enterprise-built AI models, agents and services. Sandbox Advanced also advertises instant AI verdicts on unknown files.
What support is included?
Zscaler states that customers can reach its technical support team 24/7 by ticket or phone. It also provides an online help portal with documentation and troubleshooting, product release notes, a trust portal for service health, and the Zenith peer community of 374,000+ users.
Which certifications does Zscaler hold?
The pages reviewed here (homepage, security and pricing) point to a separate Compliance page covering certifications, authorizations and audit reports but do not name specific certifications, so none are asserted in this row. Verify SOC 2, ISO 27001 and other claims on Zscaler's trust or compliance page during evaluation.
