Zscaler, founded in 2007 and headquartered in San Jose, California, is a global technology leader that has redefined modern cybersecurity through its cloud-native Zero Trust security architecture. Since its inception, the company has operated with the vision that the internet would become the new corporate network and the cloud would become the new data center. By approaching user, application, and data security independently of traditional network perimeters, Zscaler enables organizations to accelerate their digital transformation initiatives in a more secure and agile manner.
Unlike traditional firewall- and VPN-based architectures, Zscaler delivers internet access, private application access, and data protection through a single cloud-native platform. As one of the pioneers of the Security Service Edge (SSE) approach, the company provides an integrated portfolio that includes Secure Web Gateway (SWG), Zero Trust Network Access (ZTNA), Cloud Firewall, Cloud Access Security Broker (CASB), and data protection solutions. This unified architecture reduces organizations’ attack surface while improving the overall user experience. Zscaler’s globally distributed cloud infrastructure enables inline inspection of all traffic, providing real-time protection against ransomware, phishing attacks, zero-day threats, and data leakage.
Zscaler also maintains a strong position in industry analyst evaluations. The company was once again recognized as a Leader in the 2025 Gartner Magic Quadrant for Security Service Edge (SSE), where it states that it achieved the highest placement on the “Ability to Execute” axis. Furthermore, Zscaler highlights that it has been named a Leader in the SSE category for four consecutive years and has also maintained leadership positions in the Secure Web Gateway market for many years. This consistent recognition demonstrates not only Zscaler’s innovative vision but also its ability to deliver a mature, scalable, and highly effective security platform for enterprise environments.
Today, Zscaler simplifies security operations and provides centralized control by validating every connection—from users to applications, branch offices to cloud environments, and between data centers—based on identity and contextual factors. Through AI-driven analytics, extensive threat intelligence, and its platform-based architecture, Zscaler empowers security teams to operate faster, more effectively, and more proactively, creating a robust defense against modern cyber threats.
Zscaler Internet Access (ZIA) is Zscaler’s flagship secure web gateway solution, designed to secure users’ internet and SaaS traffic through the cloud. With capabilities such as SSL/TLS inspection, advanced threat protection, inline sandboxing, and URL filtering, ZIA provides strong protection against ransomware, phishing attacks, and zero-day threats. Unlike traditional web gateways, its cloud-native architecture delivers scalable security without compromising performance, enabling organizations to provide secure and seamless internet access for users regardless of location.
Zscaler Private Access (ZPA) is a modern Zero Trust Network Access (ZTNA) solution that provides secure application access without the need for traditional VPNs. By connecting users directly to only the applications they are authorized to access—rather than granting access to the entire network—ZPA significantly reduces the attack surface and minimizes the risk of lateral movement. Through Zscaler’s cloud-native architecture, organizations can enhance both security and user experience, particularly in hybrid and remote work environments.
