Jay Chaudhry and K. Kailash founded Zscaler in 2007 to rebuild corporate security as a cloud service rather than a stack of on-premise appliances. The San Jose company routes employee web and application traffic through its Zero Trust Exchange, brokering access per-session instead of trusting the network perimeter. Core products split into ZIA for internet filtering, ZPA for private app access, and ZDX for digital experience monitoring. Shares debuted on NASDAQ in March 2018 at $16, and annual recurring revenue has since crossed $2 billion as enterprises retire legacy VPNs.

Equity comp at Zscaler
- RSUs use single-trigger vesting: shares become yours as each portion vests on schedule, and the value is taxed as ordinary income at that point. No IPO or acquisition is required.

If a meaningful share of your net worth sits in ZS, concentration risk is the question. This calculator quantifies drawdown impact at 30 / 50 / 70%, and the trade-off between selling down (tax cost now) versus hedging (option premium drag), auto-filled with ZS's option-implied volatility.
Example: 5,000 ZS shares at $127.23 is a $636,150 position. A 30% drawdown costs $190,845; a 50% drawdown costs $318,075; a 70% drawdown costs $445,305. The calculator quantifies the trade-off between selling down (immediate capital-gains tax) and hedging (option premium drag) using ZS's option-implied volatility and your cost basis.

Zscaler equity questions
- How much ZS stock is too much?
- There is no single threshold, but the larger the share of your net worth in one stock, the more a single bad year can set back your plans. The calculator above quantifies the drawdown impact at 30, 50, and 70 percent for your ZS position and weighs selling down (which triggers capital-gains tax now) against hedging (which costs option premium).
- Does Zscaler grant ISOs, NSOs, or RSUs?
- Equity compensation at Zscaler typically takes the form of non-qualified stock options (NSOs) and restricted stock units (RSUs). Restricted stock units are taxed as ordinary income when they vest.
- Do Zscaler RSUs use double-trigger vesting?
- No. Zscaler restricted stock units (RSUs) use single-trigger vesting: each tranche becomes yours as it vests on schedule, taxed as ordinary income at that point, with no liquidity event required.
