Zscaler, Inc. (ZS) — Business Overview
Business Description
Zscaler is a cloud-native cybersecurity platform built on a Zero Trust architecture, replacing traditional network perimeter defenses with an inline cloud proxy that inspects all traffic — users to apps, apps to apps, and AI agents to services. Delivered from 160+ data centers processing 500+ billion transactions daily and blocking 150+ million threats, the Zero Trust Exchange platform protects ~45% of Fortune 500 companies. FY2025 revenue reached $2.673B (+23% YoY) with ARR surpassing $3 billion.
Revenue Model
Subscription-based SaaS with annual and multi-year contracts. Customers typically land with ZIA (internet access security) or ZPA (private app access), then expand to digital experience monitoring, cloud protection, data security, and AI security modules. The Z-Flex program enables flexible multi-year platform commitments, generating $175M in TCV bookings in Q4 FY2025 alone. ~25% of revenue flows through top 5 channel partners; $1B+ generated via AWS Marketplace.
Products & Services
- ZIA (Zscaler Internet Access) — secure web gateway, cloud firewall, DLP, CASB for internet-bound traffic
- ZPA (Zscaler Private Access) — zero trust network access to internal applications; replaces VPN
- ZDX (Zscaler Digital Experience) — end-to-end visibility into application and network performance
- ZCP (Zscaler Cloud Protection) — CSPM, workload protection for cloud environments
- AI Guard — security layer for AI/LLM traffic; controls agent-to-agent and agent-to-app communication
- Data Security — DLP and DSPM integrated across the Zero Trust Exchange
- Zero Trust Segmentation — prevents lateral movement from ransomware in branches and cloud environments
Customer Base & Go-to-Market
Serves 5,000+ enterprise customers including ~45% of Fortune 500. Land with ZIA/ZPA → expand to full platform (data security, ZDX, AI Guard). Channel-heavy: top 5 partners account for ~25% of revenue. Z-Flex drives multi-year platform consolidation deals. AI Security ARR exceeded $400M in FY2025. Enterprise expansion motion: customers consolidate multiple point security tools onto the Zero Trust Exchange.
Competitive Position
Zscaler competes in the $96B+ SASE/zero trust market against Palo Alto Networks, CrowdStrike, Netskope, and legacy firewall vendors (Cisco, Fortinet, Check Point). Zscaler's differentiation: purpose-built cloud-native proxy architecture (no appliances, no hardware), inline inspection of all traffic, and the network effect of processing 500B+ daily transactions providing unmatched threat intelligence. SAP RISE migrations and enterprise firewall consolidation directly benefit Zscaler as customers move away from perimeter-based architectures.

FCF profile is strong: margins expanded from 21% (FY2023) to 27% (FY2024). Q4 FY2025 FCF margins reportedly hit 52% in the quarter — reflecting operating leverage at scale. Net cash positive. Significant SBC (~20%+ of revenue) suppresses GAAP profitability but non-GAAP earnings are solidly positive.
Key Ratios (approximate)
- P/E: ~50–70x (non-GAAP FY2026E) | EV/Sales: ~10x | FCF Yield: ~2–3%
- Revenue Growth (TTM): ~23% | Non-GAAP Operating Margin: ~25%
Growth Profile
Zscaler compounded revenue from $1.09B (FY2022) to $2.673B (FY2025) — 35% CAGR — but annual growth rates decelerated sharply: 62% → 48% → 34% → 23%. This deceleration narrative drove the stock from highs (~$250+) to 60% below peak by early 2026. The ARR $3B+ milestone, Z-Flex platform deals, and AI Security ARR $400M+ represent the re-acceleration thesis. FCF quality is excellent at 27%+ margins.
Forward Estimates
- FY2026: Revenue ~$3.2–3.4B (+20–27%); FCF margin expanding toward 28–30%
- AI Security ARR: $400M → tracking toward $600M+ as AI agent traffic monitoring scales
- Z-Flex TCV bookings: $175M Q4 FY2025 → expected to drive multi-year contract backlog
- Analyst mean PT: ~$200–220 (82% Buy consensus); bull case $366; bear case ~$118–120
- RPO growth (+35%) running well ahead of revenue — leading indicator for re-acceleration
