Zscaler provides a cloud-native Zero Trust Exchange platform that secures digital transformation for global enterprises by connecting users to apps without a VPN.
Zscaler is a global leader in cloud security, recognized for pioneering the Zero Trust architecture. Founded in 2007 and headquartered in San Jose, California, the company was built to address the security challenges of a world where applications are moving to the cloud and employees are working from anywhere. Zscaler serves over 7,000 customers across all major industries, including over 40% of the Fortune 500.
The company’s flagship offering, the Zscaler Zero Trust Exchange, is a modular platform that provides comprehensive security services including Secure Web Gateway (SWG), Cloud Access Security Broker (CASB), Data Loss Prevention (DLP), and Zero Trust Network Access (ZTNA). By sitting between the user and the application, Zscaler ensures that access is based on identity and context—such as device health and location—rather than network location.
Over the past decade, Zscaler has expanded its market presence through consistent organic innovation and strategic acquisitions in areas like Cloud Security Posture Management (CSPM) and active threat deception. Their business focus is centered on helping organizations retire legacy infrastructure, such as VPNs and hardware firewalls, to reduce cost, complexity, and risk. As a dominant player in the Security Service Edge (SSE) market, Zscaler continues to lead the shift toward a decentralized, cloud-centric security model.
Company Differentiation
Zscaler is defined by its "cloud-first, cloud-only" DNA, having been founded with the conviction that traditional perimeter-based security would become obsolete. Unlike legacy hardware vendors attempting to port their software to the cloud, Zscaler built its entire business model on a multi-tenant, distributed architecture from day one. This philosophy extends to their "Zero Trust Exchange," which treats the internet as the new corporate network.
The company’s culture is deeply rooted in innovation and customer success, evidenced by their high Net Promoter Scores (NPS) and a business model that prioritizes seamless scalability. Zscaler’s approach to customer success is proactive; they act as a strategic partner in digital transformation rather than just a security utility. Their organizational uniqueness lies in their massive global scale—operating the world’s largest security cloud—which provides them with a level of threat intelligence and operational visibility that localized or hardware-dependent competitors cannot replicate. They foster a culture of "disruptive innovation," constantly challenging the status quo of networking and security to eliminate the attack surface entirely.
Zscaler Internet Access (ZIA): The 'Secure Web Gateway' equivalent. Tiers range from 'Professional' (basic URL filtering) to 'Transformation' (full SSL inspection, cloud firewall, and sandboxing).
Zscaler Private Access (ZPA): The 'ZTNA' solution. Tiers vary based on the number of applications supported and the depth of health monitoring and discovery features.
Zscaler Deception: A specialized offering that uses 'decoys' and 'honeytokens' to detect and misdirect lateral movement by attackers within the environment.
Zscaler Posture Management (ZCP/ZVM): Solutions specifically for securing cloud infrastructure (CSPM) and protecting cloud-to-cloud communications.
Zscaler Digital Experience (ZDX): A standalone monitoring module that helps IT teams diagnose why a user's Zoom call is dropping or why Salesforce is slow.
Product Differentiation
Zscaler’s product suite is anchored by the Zscaler Zero Trust Exchange, which stands apart due to its proxy-based architecture. Unlike traditional firewalls or SD-WAN solutions that perform "passthrough" inspection, Zscaler acts as a true intelligent switchboard. It terminates every connection, inspects encrypted traffic at scale without latency, and applies granular policies before re-establishing the connection to the destination.
Key technical advantages include:
- Zscaler Internet Access (ZIA): A full security stack delivered from the cloud, eliminating the need for backhauling traffic to data centers.
- Zscaler Private Access (ZPA): A revolutionary approach to remote access that uses inside-out connectivity, making applications "invisible" to the public internet and preventing lateral movement by attackers.
- Zscaler Digital Experience (ZDX): Integrated monitoring that provides end-to-end visibility into user experience, helping IT teams troubleshoot performance issues across the entire connection path.
- AI-Powered Threat Protection: By processing over 300 billion transactions daily, Zscaler’s platform uses machine learning to identify and block new threats in real-time, providing a "herd immunity" effect across its entire global customer base. These capabilities allow Zscaler to offer a consolidated SASE (Secure Access Service Edge) framework that replaces multiple point products with a single, integrated cloud platform.
