Key Investment Risks and Considerations
Investing in Zscaler involves several risks common to high-growth technology stocks.

The stock has demonstrated significant price swings, with a 52-week range from a low of $114.63 to a high of $336.99. Execution risk is present, as the company must continue to innovate and integrate new technologies like AI security to maintain its leadership position.
