Philippe Courtot took over the company in 1999 and made an early bet that vulnerability scanning belonged in the cloud rather than on appliances customers maintained. Scanners sit inside customer networks and report to a hosted platform, which made continuous assessment practical across large estates. The product line grew into asset inventory, patch management, compliance reporting, and web application scanning, sold as modules on one platform. Headquarters are in Foster City, California, and the company has run profitably for longer than most security vendors its size.

Qualys equity questions

How much does it cost to hedge QLYS stock?
The cost of a protective put depends on how far below the current price you set the floor, how long the protection lasts, and QLYS's option-implied volatility. A zero-cost collar lowers that cost by selling away some upside. The calculator above prices both structures off the current QLYS option chain and shows the annual cost, maximum loss, and tax treatment.
Does Qualys grant ISOs, NSOs, or RSUs?
Equity compensation at Qualys typically takes the form of restricted stock units (RSUs). Restricted stock units are taxed as ordinary income when they vest.
Do Qualys RSUs use double-trigger vesting?
No. Qualys 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.
