Executive Commentary
"AI represents one of the most significant opportunities in Zscaler's history. By connecting users, workloads, branches, and now agents directly to the applications they need without placing them on the network, we are uniquely equipped to help companies both combat the threats created by agentic AI and securely deploy AI agents and models,"
Jay Chaudhry, Chairman and CEO
"Our growth engine continues to broaden beyond users with increasing contribution from non-seat-based solutions, continued Z-Flex momentum, record large deal activity, and improved sales productivity. ARR momentum remains strong in Q4, and we are confident in our ability to continue to drive profitable growth across multiple vectors,"
Kevin Rubin, CFO
Strategic Positioning
1. AI Security as a Core Differentiator
Zscaler’s integrated security for AI portfolio addresses both emerging threats and safe AI adoption, including data loss prevention, policy enforcement for AI agents, and secure agentic communication. The company’s ability to combine AI security with its established zero trust platform is winning significant new logo and upsell deals, with security for AI bookings increasing over 50% sequentially in Q4. This positions Zscaler as a key partner for enterprises navigating AI risk.
2. Expansion of Zero Trust Everywhere
Adoption of zero trust solutions beyond users to branches, cloud workloads, and IoT devices is accelerating. The company’s Zero Trust Branch and Zero Trust Cloud offerings saw meaningful momentum, with over 950 enterprises adopting Zero Trust Everywhere by quarter-end, nearly tripling from the prior year. This broad platform adoption supports higher customer retention and cross-selling potential.
3. ZFlex Contract Model Enhances Customer Engagement
ZFlex, a flexible multi-year contract offering, enables customers to activate or swap modules without new procurement cycles, facilitating faster upsell and platform expansion. With $1.7 billion in bookings and an average ARR uplift of nearly 30% for ZFlex customers in fiscal 26, this model strengthens customer relationships and revenue visibility.
4. Sales Organization Transformation and Channel Expansion
Transitioning from opportunity-led to account-focused sales, Zscaler achieved its highest quarterly and annual sales productivity in four years. The company is expanding dedicated new logo sales teams and deepening channel partnerships, particularly targeting mid-market and SMB segments. This strategic investment aims to accelerate new logo acquisition and broaden market penetration.
5. Integration of Red Canary and Agentic SecOps Launch
The acquisition of Red Canary has enabled Zscaler to launch its agentic SecOps solution, integrating AI-driven detection, investigation, and response capabilities at machine speed. This closed-loop remediation capability addresses the shrinking window between vulnerability discovery and exploitation, offering a disruptive alternative to traditional human-centric SOC models.
Key Considerations
Zscaler’s Q4 results reflect the company’s successful navigation of a rapidly evolving cybersecurity landscape shaped by AI advancements. Key considerations for investors include:
- AI as a Strategic Growth Lever: The company’s comprehensive AI security offerings are a catalyst for new customer acquisition and upsell, shaping its competitive differentiation.

- Sales Leadership Transition: Recent changes in sales leadership and ongoing onboarding may influence execution in the first half of fiscal 27, as reflected in guidance.
- Red Canary Integration: While Red Canary’s standalone ARR growth is expected to be limited, its technology underpins the new agentic SecOps platform, enhancing product differentiation.
Risks
Zscaler faces risks related to macroeconomic uncertainty, competitive pressures from emerging AI security startups, and the execution complexity of integrating new technologies such as Red Canary. Additionally, elevated capital expenditures and sales leadership transitions pose near-term operational risks. The evolving regulatory environment around AI and data privacy also presents potential challenges.
Forward Outlook
For Q1 fiscal 2027, Zscaler expects revenue between $935 million and $939 million, representing approximately 19% year-over-year growth, with a non-GAAP operating margin near 23%. The company projects ARR growth of 16.6% to 17.4% for the full year, with revenue guidance of $3.91 billion to $3.94 billion. Management anticipates free cash flow margins of 23% to 23.5%, with CapEx remaining elevated due to component cost pressures and infrastructure investments. The outlook reflects continued momentum in AI security and Zero Trust Everywhere adoption, tempered by sales organization transitions in the first half of the year.
