Data InfoMetrix tracks 24,756 companies using Zscaler, with 165,933 verified contacts at those accounts as of October 2026. Counts are estimates from our database and market research, so ask us for a live count for your exact criteria.

Q: Who buys and manages Zscaler inside a company?

Zscaler is usually owned by Zero Trust Architecture, Network Security & Cloud Transformation Leadership. Decision-makers include Chief Information Security Officer (CISO), VP Network Security and VP IT Infrastructure; Lead Zero Trust Architect and Cloud Network Engineer shape the choice, and Network Security Engineer and Zscaler Administrator use it day to day. Our Zscaler list can include any of these roles.

Q: Which Zscaler products or editions can I target?

You can target accounts by the Zscaler products they run, including Zscaler Internet Access (ZIA Enterprise), Zscaler Private Access (ZPA Zero Trust), Zscaler Digital Experience (ZDX), Zscaler Cloud Protection (ZCP) and Zscaler Zero Trust Exchange Suite. Tell us which edition or module matters and we filter the list to those accounts.

Q: What does Zscaler integrate with?

Zscaler is most often connected to Okta, CrowdStrike, Microsoft Azure, Splunk and ServiceNow, so users of those tools overlap heavily with Zscaler accounts. We can filter any list by this kind of stack overlap.

Q: What are the main alternatives to Zscaler?

The main alternatives to Zscaler are Palo Alto Networks Prisma Access, Cloudflare Zero Trust, Netskope SASE and Cato Networks. We also keep verified user lists for Palo Alto Networks Prisma Access, Cloudflare Zero Trust, Netskope SASE and Cato Networks, which is useful for competitive displacement campaigns.

Q: What challenges do Zscaler customers face?

Common challenges for Zscaler accounts include ZIA vs. ZPA vs. Full SASE Footprint Disconnect, Reaching Traditional Network Admins Instead of Zero Trust Leaders and Co-Existing Identity & Endpoint Stack Blind Spots. Reaching an account running only ZIA for outbound web security with an internal private access pitch fails if you do not know whether they have licensed ZPA. Data InfoMetrix isolates exact Zscaler module deployments. These are good angles for outreach to Zscaler users.

Yes. Data InfoMetrix delivers a complimentary 10-record sample tailored to your target Zscaler criteria—including target job titles, company size, and region—delivered within one business day with no obligation.
