Zscaler Tech Stack
Cloud security platform processing 500B+ daily transactions with Zero Trust architecture
Zscaler operates an in-line cloud security platform handling over 500 billion transactions daily, preventing billions of security incidents across a customer base of thousands. The tech stack reflects a cloud-native, polyglot engineering org: Kubernetes and multi-cloud (AWS, GCP, Azure) underpin the infrastructure, while backend services span Java, Go, C++, and Python. Active adoption of DLP, CASB, Splunk Enterprise Security, and dbt signals expansion into data protection and analytics—paired with hiring momentum in sales and engineering—indicating scaling of both platform breadth and go-to-market capacity.
