Zscaler is the leader in cloud security, pioneering the Zero Trust security architecture that has become essential for modern enterprises. The Zscaler Zero Trust Exchange platform protects thousands of customers from cyberattacks and data loss by securely connecting users, devices, and applications in any location.
As of Q2 FY2026 (January 31, 2026), Zscaler demonstrates exceptional financial momentum with ARR growing 25% year-over-year to $3,359 million and revenue of $815.8 million, an increase of 26% year-over-year. The company is operating at a Rule-of-62, significantly exceeding industry benchmarks.
Organizations racing to adopt AI are looking to Zscaler to provide the security solution they trust, positioning the company at the intersection of two massive secular trends: Zero Trust adoption and AI security.
Zscaler delivered strong second-quarter results that exceeded guidance on both revenue and profitability metrics:
The first quarter set a strong foundation for the fiscal year:
For the full year of fiscal 2026, the company expects Annual Recurring Revenue of $3.730 billion to $3.745 billion, growth of 24%, up from previous guidance. Revenue of approximately $3.309 billion to $3.322 billion, growth of 24%, up from prior guidance.
Distributed across more than 160 data centers globally, the SASE-based Zero Trust Exchange is the world's largest in-line cloud security platform. This platform represents a fundamentally different approach compared to traditional firewall-based security.
The Zscaler Zero Trust Exchange is a comprehensive, integrated platform that enables zero trust security and network transformation for all users, workloads, IoT/OT, and B2B partners. Based on the zero trust principle of least-privileged access, the unique proxy architecture enables full TLS/SSL inspection at scale.
Secure Web Gateway that provides cloud-delivered firewall, sandbox, SSL inspection, and threat prevention for all internet and SaaS traffic.
The world's most deployed ZTNA platform. As a cloud native service, ZPA can be deployed in hours to replace legacy VPNs.
The acquisition extends the Zero Trust Exchange platform with critical capabilities like shift-left AI asset discovery and automated red teaming.
Comprehensive data loss prevention and cloud access security broker capabilities providing visibility and control across all channels.
Centralizes and standardizes workload security management across all clouds through a single framework with real-time traffic inspection.
Introduces end-to-end visibility and device scoring, providing IT teams unprecedented visibility to proactively remediate performance issues.
Zscaler can deliver full SSL inspection and inline protections at scale, securing 500 billion transactions per day at 160+ locations worldwide. This scalability is unmatched by appliance-based competitors.
Zscaler operates in the highly competitive Security Service Edge (SSE) and Secure Access Service Edge (SASE) markets. Zscaler has a rating of 4.7 stars with 1126 reviews on Gartner Peer Insights, demonstrating strong customer satisfaction.
| Competitor | Approach | Key Strengths | Zscaler's Advantage |
|---|---|---|---|
| Palo Alto Networks (Prisma SASE) | Network-centric, VM-based | Comprehensive platform, strong brand in firewalls | Palo Alto backhaults traffic to single-tenant VMs that degrade performance. Zscaler's multitenant proxy architecture delivers services at the edge with zero performance degradation |
| Cloudflare One | Performance-first CDN + security | 46% faster than Zscaler for ZTNA according to Cloudflare benchmarks | Zscaler offers deeper security inspection and enterprise-grade DLP. Focused security vs. multi-product approach |
| Cisco Umbrella | DNS-layer security + SWG | Cisco ecosystem integration, networking heritage | Cloud-native from inception vs. retrofitted legacy architecture |
| Netskope | Cloud-proxy, data-centric | Primary choice for cloud-first, data-sensitive organizations with best visibility and control for SaaS | Broader platform with stronger ZTNA and workload security capabilities |
| Fortinet/Check Point | Firewall-centric | Cost-effective, broad product portfolio | True cloud-native vs. appliance-based thinking |
Zscaler and Netskope approach security from a cloud-proxy perspective (SSE), focusing on the user-to-app connection. Palo Alto Networks and Cato approach the problem from a networking foundation. This architectural difference is fundamental.

Considerations:
Recent strategic acquisitions demonstrate thoughtful platform expansion:
These acquisitions target high-growth adjacencies (AI security, browser isolation) rather than revenue roll-ups, indicating strategic sophistication.
Zscaler is owned by 53.10% institutional shareholders, 26.03% Zscaler insiders, and 20.88% retail investors. This ownership structure provides a balance between institutional governance and insider alignment.
| Shareholder | Ownership % | Shares (Approx) | Notes |
|---|---|---|---|
| Ajay Mangal | 16.7% | 26.84M | Largest individual shareholder (family trust of founder) |
| Jay Chaudhry (CEO) | ~17% | ~27M | Second-largest shareholder who also holds the title of Chief Executive Officer |
| Vanguard Group | 7.2% | 11.42M | Leading index fund provider |
| BlackRock | 4.9% | 7.83M | Increased holdings by 0.10% in recent quarter |
| State Street | ~3-4% | ~5-6M | Major institutional holder |
The significant insider ownership (26%) is a strong positive signal:
Institutional Quality: Blue-chip institutional investors (Vanguard, BlackRock, State Street) provide validation of investment thesis and governance oversight. Because institutional owners have a huge pool of resources and liquidity, their investing decisions tend to carry a great deal of weight.
Zscaler continues to see robust demand across all three of its growth pillars: AI Security, Zero Trust Everywhere, and Data Security.
AI Security pillar grew over 80% year over year, exceeding the FY26 target of $400 million ARR three quarters earlier than expected.
Successfully expanded Zero Trust Everywhere initiative, securing over 4500 enterprises, surpassing target three quarters ahead of schedule.
Comprehensive DLP, CASB, and data governance capabilities addressing increasing regulatory requirements and data residency needs.
Zscaler introduced the ZFlex program, which generated over $175 million in total contract value, growing over 70% quarter over quarter, providing customers flexibility in module adoption. This land-and-expand motion drives NDR (Net Dollar Retention).
Base Case (60% probability): Zscaler maintains ~23-25% ARR growth through FY2027, reaching $5.5B ARR with expanding margins to 25%+ non-GAAP operating margin. Stock fairly valued at 9-10x ARR multiple = ~$50-55B market cap (+40-50% upside).
Bull Case (25% probability): AI security adoption accelerates, driving 30%+ growth and 50%+ market share in Zero Trust. ARR reaches $6.5B+ by FY2027 with 28% operating margins. Premium 12x ARR multiple = $75-80B market cap (+100%+ upside).
Bear Case (15% probability): Competition intensifies, growth decelerates to 15-18%. Margins expand slowly. 7x ARR multiple = $35-40B market cap (-5 to +10% upside).
1. Market Leadership in Secular Growth Category: Zero Trust and SASE represent multi-decade transitions as enterprises abandon castle-and-moat network security. Zscaler is the pure-play leader with cloud-native architecture competitors are still trying to replicate.
2. AI Security Inflection: The AI security opportunity is just beginning. Zscaler pioneered Zero Trust security with cloud-native switchboard architecture, and by integrating SPLX technology, is expanding best-in-class AI Security solutions. This positions the company at the intersection of two mega-trends.
3. Accelerating Profitability: The company has demonstrated operating leverage with non-GAAP operating margins expanding to 22%+ while maintaining 25%+ revenue growth. This Rule-of-62 performance is exceptional for a company at this scale.
4. Founder-Led with Proven Track Record: Jay Chaudhry has built and successfully exited four security companies before Zscaler. His 16.7%+ ownership stake ensures alignment with shareholders.
5. Large TAM with Low Penetration: Global cybersecurity market exceeds $200B+ and growing. SSE/SASE segment is $25-30B growing 25%+ annually. Zscaler has only penetrated a fraction of addressable market.
Allocation: 2.5-4.0% portfolio weight
Time Horizon: 3-5 years
Entry Strategy: Build position over 2-3 months, with 50% initial position and add on any 10%+ pullbacks
Exit Triggers: (1) Deceleration below 18% ARR growth for two consecutive quarters, (2) Loss of key customers or competitive displacement, (3) Founder departure without strong succession
