Zscaler was founded in 2007 to secure users with Zero Trust, on the visionary idea that the internet would be the new corporate network, as the cloud becomes the new data center.
We then extended our platform to deliver Zero Trust for workloads, branches, and devices, which has increased our TAM significantly and extended our technology lead.
We are now extending our global Zero Trust ExchangeTM to secure AI applications, AI agent communication, and agentic workflows at scale. Just as we enable customers to securely accelerate digital transformation and cloud adoption, we believe we’re uniquely positioned to secure the AI transformation, driving continued demand for our platform.

“Zscaler is ideally positioned as the cybersecurity platform for the AI era. Our differentiated Zero Trust SASE architecture, which hides applications from attackers and eliminates lateral movement, has never been more essential in securing against threats exposed by frontier models and compromised AI agents,” said Jay Chaudhry, CEO, Chairman and Founder of Zscaler. “Our results demonstrate that our approach is resonating as we attract new customers and expand with our existing customers, and we see ample runway for long-term growth.”

Zscaler Central Authority (CA) monitors our entire security cloud and provides a central location for software and database updates, policy and configuration settings and threat intelligence. The collection of CA instances together act like the brain of the cloud, and they are geographically distributed for redundancy and performance.
Customer traffic gets directed to the nearest Zscaler Enforcement Node (ZEN), where security, management and compliance policies are enforced. Our differentiated authentication and policy distribution mechanism that enables any user to connect to any ZEN at any time to ensure full policy enforcement. ZEN utilizes a full proxy architecture for in-line traffic inspection and is built to ensure data is not written to disk to maintain the highest level of data security. Logs are continuously created in memory and forwarded to our logging module.
Compressed logs are transmitted to our Nanolog Servers over secure connections and multicast to multiple servers for redundancy. Our dashboards provide visibility into our customer’s traffic to enable troubleshooting, policy changes and other administrative actions. Our analytics capabilities allow customers to interactively mine billions of transaction logs to generate reports that provide insight on network utilization and traffic. Regardless of where users are located, customers can choose to have logs stored in the US, the EU or Switzerland as well as streamed to a third-party SIEM.
The Zscaler Zero Trust Exchange employs a single-scan, multi-action (SSMA) architecture to minimize latency, improve user experience, and enable an integrated, extensible platform.
Single-Scan
Traffic is entered into memory only once
Multi-Action
Multiple security engines simultaneously inspect the packet
Extensibility
New inspection engines can be added over time, without impacting performance
Zscaler has invested heavily into building a ‘proxy' based architecture that deeply inspects network traffic at an enormous scale, including SSL/TLS encrypted traffic. Think about it like a postal service.
