The sector median covers every company in the sector on the US market, loss-making ones included.
Zscaler inspects a company's network traffic in its own cloud — instead of an appliance sitting in the office.
The old security model was built around a perimeter: trust inside the network, distrust outside. When employees work from anywhere and applications live in clouds, there is no perimeter left. The company offers a different principle: every connection is checked separately, and traffic routes through its own network of points of presence worldwide.
The product is sold as a per-employee subscription, so revenue is predictable and grows with the customer's headcount. The barrier to entry is the network itself: rebuilding one is expensive and slow. Risks: competition from network hardware makers that moved to the cloud, and caution in security budgets. The company pays no dividend.
