What could invalidate the ZS thesis
If you own Zscaler, Inc. (ZS), the question that matters is not where the price is. It is which of your reasons could break, and what would prove it. Here is the bull case and the specific risks that would invalidate it.

How to monitor the ZS thesis
Knowing the risks is step one. The harder part is noticing when one actually fires, because the evidence lives in SEC filings and earnings calls, not in the price you check every day. The discipline is simple: write down the reasons you own ZS, decide what would break each one, then watch the primary sources against that list.
That is what Helm does automatically. You write the pillars behind ZS, and Helm scores filings, earnings, news, and price against each one, then tells you with a dated, verbatim citation when a reason weakens or breaks. Read more on how thesis monitoring works.
