About Zscaler
Zscaler provides a cloud-based cybersecurity platform built on zero trust principles. Its main offering, the Zero Trust Exchange, sits inline on every connection and allows each entity to reach only what it is authorised to access. This approach aims to make the attack surface disappear. The platform secures users, data, AI agents, and models, and helps security operations centres stop threats quickly. Zscaler sells to large enterprises, including many Fortune 500 companies, and serves industries such as financial services, manufacturing, and transportation. It also partners with organisations like the Aston Martin Aramco Formula One team, which uses the Zero Trust Exchange to protect its infrastructure. The company operates globally with over 150 data centres and more than 6,000 employees. It processes over 750 billion transactions daily. Zscaler holds certifications such as ISO 27001, SOC 2 Type 2, and Cyber Essentials Plus. It also runs Zenith Ventures, which invests in cybersecurity startups that build on its platform.
