Companies that use Zscaler

I noticed Zscaler purchases are driven primarily by security and infrastructure leaders, with Directors of Information Security (14%), Network Engineers (13%), and Directors of Information Technology (11%) representing the core buying committee. These roles span from strategic leadership positions overseeing entire security programs to technical directors managing network transformation initiatives. Their hiring priorities reveal organizations investing heavily in Zero Trust architecture, cloud migration, and replacing legacy VPN infrastructure with modern secure access solutions.

The day-to-day users are predominantly network and security engineers who implement and maintain Zscaler's suite of products including ZIA, ZPA, ZDX, and ZCC. These practitioners handle policy configuration, user and group management, log analysis, troubleshooting connectivity issues, and integrations with identity providers. I found multiple references to engineers who "configure and tune the system to optimize performance," "manage technical discussion with internal infra teams," and "provide ongoing operational support, maintenance, and engineering" across the full Zscaler product suite.

The pain points center on digital transformation and hybrid cloud security. Companies explicitly mention needs like "accelerates digital transformation so our customers can be more agile, efficient, resilient, and secure" and seek professionals who can "design and implement SD-WAN, SASE, and Zero Trust frameworks to deliver secure, scalable, and cloud-integrated connectivity." Organizations are moving away from traditional perimeter security toward "protecting every identity: human, non-human, and AI" while enabling remote workforces and multi-cloud environments.

I noticed that Zscaler's customers span an incredibly diverse range of industries, but they share a common thread: they're companies operating critical infrastructure or managing complex, distributed operations. These aren't just software companies. I'm seeing multinational banks like SCB and Siam Commercial Bank, industrial manufacturers like Flender and ASM producing semiconductor equipment, healthcare providers like Abiomed making life-saving medical devices, global food companies like Grupo Bimbo and Royal Canin, and even government entities like Bedford Borough Council. What connects them is operational complexity and the need to protect sensitive data across multiple locations.

Looking at company maturity, these are predominantly established enterprises. The employee counts tell the story: I'm seeing numerous companies with 1,000+ employees, many with 5,000-10,000+, and several massive organizations like IOM with over 22,000 employees. Even smaller companies in this dataset typically have 50-200+ employees and describe decades of operating history. Very few are early-stage startups. These are companies with complex IT environments, multiple offices, and significant security requirements.

I noticed that Zscaler users represent a very specific profile: enterprise organizations with mature security postures and distributed workforces. The combination of Zscaler with Proofpoint Email Security, ServiceNow, and DocuSign tells me these are established companies that have moved beyond basic security tools and need comprehensive solutions for a complex, modern work environment. They're operating at significant scale with employees working across multiple locations who need secure access to resources from anywhere.

The pairing of Zscaler with ServiceNow is particularly revealing. These companies are running sophisticated IT operations with formal ticket management, change control processes, and likely have dedicated security teams. When I see Docker Business alongside this, it suggests they're also supporting developer teams who need secure access to cloud resources and containers. The presence of Miro and Smartsheet indicates extensive collaboration across distributed teams, exactly the use case where traditional VPNs break down and zero trust architecture becomes essential.

My analysis shows these are sales-led enterprises in growth or mature stages. The DocuSign correlation with over 2,000 companies using it suggests high-velocity contracting processes, likely with enterprise sales teams closing deals that require legal review and executive signatures. Smartsheet and Miro point to complex project coordination across departments. These aren't scrappy startups, they're organizations with established revenue streams investing heavily in both productivity and security infrastructure.
