CYBR vs. ZS: Which Cybersecurity Stock is the Better Buy Now?

An analysis comparing cybersecurity stocks CyberArk (CYBR) and Zscaler (ZS) concludes that CyberArk presents a more compelling investment case. CyberArk is poised for strong growth, leveraging AI-driven identity security with machine identities now vastly outnumbering human ones, and enhancing its platform through innovative AI products like Secure AI Agents and strategic acquisitions, which underpin projected revenue growth of 31% in 2025. Conversely, Zscaler, despite expanding its Zero Trust offerings, faces near-term profitability pressures from substantial sales & marketing and R&D investments, with its fiscal 2026 earnings forecast to decline by 3.5%.

Analysis

CyberArk (CYBR) and Zscaler (ZS) are both capitalizing on the high-growth cybersecurity sector, but their near-term financial trajectories are diverging significantly. CyberArk is demonstrating strong fundamental momentum, driven by its strategic focus on identity security, particularly in the rapidly expanding area of machine identities, which now outnumber human ones 80 to 1. This focus is translating into tangible results, with machine identity products featuring in nine of its ten largest deals in the first quarter of 2025. Furthermore, CYBR is enhancing its platform through AI innovations like Secure AI Agents and strategic acquisitions such as Venafi, supporting robust consensus forecasts for 31% revenue growth and 26.4% earnings growth in 2025. In contrast, Zscaler faces considerable headwinds despite its expansion in Zero Trust architecture. The company's strategy requires substantial investments in sales, marketing, and R&D, which are squeezing profitability and have led to a projected 3.5% year-over-year earnings decline for fiscal 2026. While ZS stock has outperformed YTD with a 74.4% gain versus CYBR's 19.6%, its valuation on a forward sales basis is lower at 6.65x compared to CYBR's 13.6x, reflecting the market's pricing of CYBR's superior growth profile against ZS's margin challenges.

Key Decisions for Investors

• Investors may find CyberArk's premium valuation of 13.6x forward sales justified by its strong fundamental outlook, underscored by leadership in machine identity security and projected 2025 revenue and earnings growth of 31% and 26.4%, respectively.
• Caution is warranted for Zscaler, as its significant 74.4% year-to-date share price appreciation appears disconnected from its underlying fundamentals, which include notable margin pressure and a forecast 3.5% earnings decline for fiscal 2026.
• A relative value analysis suggests favoring CyberArk over Zscaler, given the divergence in their near-term profitability and fundamental growth trajectories.
• Monitor Zscaler's upcoming financial reports for any improvement in operating leverage, as a failure to control rising S&M and R&D expenses could further challenge its valuation.
