Zscaler (ZS) is establishing new benchmarks in the cloud security industry through strategic platform expansion that addresses emerging AI security requirements, comprehensive Zero Trust architecture deployment, and enterprise data protection needs.

Zscaler serves enterprise customers globally through its comprehensive cloud security platform, which spans Zero Trust network access, internet security, data protection, and emerging AI security capabilities.

Core offerings include Zero Trust Everywhere architecture, Data Security Everywhere solutions, and AI security innovations delivered through scalable cloud-native infrastructure.

The cybersecurity leader delivered record Q4 revenue of $719 million, growing 21% year-over-year, with annual recurring revenue surpassing $3 billion to join an exclusive group of only two pure-play SaaS security vendors achieving this milestone.

Zscaler demonstrates exceptional execution across platform expansion initiatives under the leadership of CEO Jay Chaudhry.

It secured nearly 40% of Global 2000 companies and over 45% of Fortune 500 companies, while achieving more than 350 Zero Trust Everywhere enterprise deployments ahead of fiscal 2026 targets.

Zscaler’s strategic transformation focuses on three growth vectors totaling over $1 billion in ARR:

  • AI Security addressing emerging threats and agentic operations
  • Zero Trust Everywhere is expanding beyond users to branches and cloud workloads, and
  • Data Security Everywhere is consolidating multiple point products onto a unified platform

With initiatives including the acquisition of Red Canary for agentless security operations, the Z-Flex program generating over $100 million in bookings, and comprehensive AI security solutions, Zscaler continues to build market leadership while capturing expanding cybersecurity requirements.

The company completed the Red Canary acquisition for approximately $83 million in ARR and maintains a strong balance sheet with $3.6 billion in cash while operating an efficient capital allocation strategy focused on technology innovation and strategic acquisitions.

ZS stock went public in 2018 and has since returned more than 700% to shareholders. Here’s why Zscaler stock could deliver strong returns through 2028 as it capitalizes on AI security opportunities while scaling its Zero Trust and data security platform expansion across its enterprise customer base.
