The company is expected to report strong earnings growth of 20.83% YoY with revenue projected at $937.61 million (up 18.97% YoY). However, Zscaler holds a Zacks Rank of #3 (Hold) with a Forward P/E of 46.57, trading at a discount to its industry average. The Security industry ranks in the bottom 31% of all industries.

Zscaler (ZS), a cloud-based security solutions provider, receives a #3 (Hold) rating on the Zacks Rank but shows strong growth potential with a Grade A Growth Style Score.

Zscaler faces a growth slowdown with FY27 revenue expected to increase only 17% compared to 25% in FY26. However, the company's AI security products show promise, with Security for AI bookings surging over 50% sequentially in Q4.

Zscaler (ZS) shares surged 45.1% in three months, outperforming peers like Fortinet, CrowdStrike, and Palo Alto Networks. The rally is supported by strong Q4 FY26 results with 24.9% revenue growth and AI security bookings up 50% sequentially. However, revenue growth is expected to slow to 17% in FY27, capital spending is rising, and free cash flow margins are declining. The stock trades at a reasonable 8.60x forward P/S ratio, but existing shareholders should hold while new investors should wait for a better entry point.

With the S&P 500 trading at historically elevated valuations (second-highest since the dot-com bubble), rising inflation, interest rate hikes, and potential AI development slowdowns pose risks to the market. The article recommends three stocks as potential buying opportunities if a market correction occurs: Zscaler for its zero-trust cybersecurity solutions, Uber for its autonomous vehicle partnerships, and DigitalOcean for its AI data center infrastructure.

Despite strong year-to-date stock performance (+80%), Cloudflare trades at a significantly elevated valuation (P/S ratio of 35.81 vs. industry average of 4.44) and carries a Zacks Rank #3 (Hold) rating.
