Will GenAI and SaaS Adoption Fuel Zscaler's Data Security Expansion?

Zscaler (ZS) is experiencing strong growth in its data security business, driven by the increasing adoption of GenAI and SaaS across industries; in Q3 FY25, Zscaler secured a seven-figure ACV deal with a Fortune 100 food and beverage company and expanded its relationship with a Fortune 50 auto firm, growing that customer's annual spend by over 50% to above $10 million. Zscaler's stock has surged 69.1% YTD, outperforming the security industry's 20.2% growth, and trades at a forward P/S ratio of 15.1x, slightly above the industry average of 14.52x.

Analysis

Zscaler is demonstrating significant traction with its "Data Security Everywhere" strategy, capitalizing on the expanding need for comprehensive data protection driven by widespread GenAI and SaaS adoption across diverse industries beyond traditionally regulated sectors. In its third quarter of fiscal 2025, the company secured notable large enterprise deals, including a seven-figure annual contract value (ACV) expansion with an existing Fortune 50 automotive client, increasing their annual spend by over 50% to exceed $10 million through the adoption of six of Zscaler's eight data security modules. Additionally, Zscaler landed a new seven-figure ACV deal with a Fortune 100 food and beverage company, underscoring its broadening market penetration. While competitors like Palo Alto Networks and CrowdStrike are also advancing their AI-driven security platforms, Zscaler's stock has significantly outperformed, surging 69.1% year-to-date versus the security industry's 20.2% growth. The company trades at a forward price-to-sales ratio of 15.1x, a slight premium to the industry average of 14.52x. Consensus estimates project a marginal year-over-year earnings decline of 0.31% for fiscal 2025, followed by 12.13% growth in fiscal 2026, with recent upward revisions to these estimates suggesting improving sentiment despite a current Zacks Rank #3 (Hold) rating.

Key Decisions for Investors

• Investors should recognize Zscaler's robust growth momentum and expanding enterprise adoption driven by secular trends in GenAI and SaaS, which supports a positive long-term outlook.
• Careful consideration of Zscaler's current valuation at a 15.1x forward P/S ratio, slightly above the industry, is warranted, particularly in light of its significant 69.1% year-to-date stock appreciation and the competitive landscape.
• Monitor upcoming earnings reports for sustained deal momentum and margin evolution, especially given the flat earnings projection for fiscal 2025 before an anticipated return to growth in fiscal 2026, and weigh this against the recent upward estimate revisions and the current Zacks Rank #3 (Hold) status.
