Zscaler, Inc. () is a cloud security firm headquartered in San Jose, California, specializing in cloud-delivered solutions designed to safeguard corporate networks and information assets.
History
Established in 2007 by Jay Chaudhry and K. Kailash, Zscaler introduced its cybersecurity platform a year later, in 2008.
In August 2012, the company secured $38 million in investment funding. Subsequently, its second financing round raised $100 million in August 2015, with TPG Capital leading the investment.
Zscaler made its public market debut in March 2018, generating $192 million through an initial public offering. It is listed on the Nasdaq stock exchange under the symbol ZS and was incorporated into the Nasdaq-100 index as of December 17, 2021.
Zero Trust Exchange
The Zero Trust Exchange platform by Zscaler combines threat defense, data protection, zero trust connectivity, and operational analytics into a unified solution. This platform was unveiled at Zenith Live in June 2023.
In January 2024, Zscaler introduced its Zero Trust SASE (secure access service edge) product, representing its inaugural single-vendor SASE solution. Powered by an AI-driven SSE platform, it enables secure connections among users, locations, and cloud applications through the Zero Trust Exchange. Additionally, Zscaler offers its cloud-native cybersecurity service known as Zscaler Internet Access.
Acquisitions
Zscaler has pursued growth through a series of targeted acquisitions: integrating TrustPath's AI and machine learning capabilities in 2018; acquiring Appsulate for $13 million in 2019; followed by Cloudneeti and Edgewise Networks in 2020; Trustdome in 2021; the Indian startup Smokescreen Technologies also in 2021; and ShiftRight for $25.6 million in 2022.
In February 2023, Zscaler expanded its portfolio by acquiring Canonic, an Israeli company specializing in application security with a focus on SaaS attack defense. The following year, in March 2024, it secured two Israeli startups—Avalor, an AI-powered data security firm, for $310 million, and Airgap Network, which specializes in network segmentation, for an undisclosed amount.
On May 17, 2025, Zscaler revealed the acquisition of Red Canary, a US-based provider of Managed Detection and Response services; however, the financial details of this transaction were not made public.
