Stock Analysis · Zscaler Inc (ZS)

Overview

Zscaler is a cloud cybersecurity company focused on securing internet traffic, applications, and data without relying on traditional on-premise security hardware. Its platform sits between users, devices, and the applications they access, helping companies inspect traffic, enforce security policies, and connect employees or partners to internal systems more safely. This approach is often associated with zero trust security, where access is granted based on identity, context, and policy rather than broad network access.

The business model is largely subscription-based. Customers pay recurring fees to use Zscaler’s cloud-delivered security services, which makes revenue more predictable than a product business built around one-time hardware sales. The company serves large enterprises and government-related organizations that are moving users, applications, and workloads to the cloud.

Based on company filings, revenue is reported primarily in two categories:

• Subscription and support: about 95% to 96% of revenue. This includes access to Zscaler’s security cloud and related support services. The main products include internet access security, private application access, digital experience monitoring, and data protection capabilities.
• Professional services and other: about 4% to 5% of revenue. This includes implementation, training, and related advisory work that helps customers deploy and optimize the platform.

Zscaler’s financial structure also shows a typical software profile: very high gross margins, heavy spending on research and development, and meaningful sales investment to win large customers. Over the last several years, revenue and gross profit have expanded strongly, while operating losses have narrowed substantially even if full GAAP profitability remains slightly negative.

The broad pattern is encouraging: revenue has roughly tripled since fiscal 2022, gross profit has risen alongside it, and operating losses have shrunk from very large levels to near break-even. At the same time, research and development spending has climbed sharply, showing that Zscaler is still investing aggressively to extend its platform.

Key Figures

Zscaler stands out for growth much more than for classic valuation or profitability measures. Its growth profile ranks near the top of the software infrastructure group, supported by revenue growth around the mid-20% range and a five-year free cash flow expansion rate far above the sector median. The weaker areas are valuation and accounting profitability: cash flow yield is lower than the sector median, operating margin is still slightly negative, and return on invested capital remains below many peers. The stock’s recent trading pattern has also been volatile, with a sharp rebound over six months following a much weaker earlier 12-month stretch.

Growth

Cybersecurity remains one of the more durable areas of enterprise technology spending. Even when companies slow broader IT budgets, protecting users, applications, and data usually stays high on the priority list. Within cybersecurity, cloud-delivered security and zero trust architectures are supported by long-term trends such as remote and hybrid work, rising use of software-as-a-service applications, migration of internal applications to the cloud, and the need to secure AI-related data flows and machine identities.

Zscaler’s strategy is well aligned with those trends. Instead of protecting a fixed corporate perimeter, it is built for a world where employees connect from many locations and applications live across multiple environments. That architecture can become more relevant as older network security designs look less efficient for cloud-first organizations. The company has also expanded beyond its original web security roots into private application access, cloud workload communication, data protection, and user experience monitoring, giving it more room to sell additional services into existing accounts.

The growth rate has cooled substantially from the exceptional 60%+ levels seen earlier in the decade, but that is normal for a business that has become much larger. What matters more is that revenue growth has stabilized around the mid-20% range recently, which still compares favorably with much of the sector. Five-year revenue per share growth of roughly 28% and five-year EPS growth above 30% also show that expansion has not been limited to top-line scale alone.

Cash generation is another important positive. Free cash flow has increased dramatically over the last several years, moving from under $200 million to close to $1 billion on a trailing basis. That matters because it shows customers are paying reliably and the platform can convert scale into real cash even before full GAAP net income turns positive. In software, that is often a sign of an economically strong recurring-revenue model.

Recent company announcements and investor communications have continued to highlight demand for zero trust security, platform consolidation, and newer modules tied to data security and AI-related protection. These areas matter because many large enterprises want fewer vendors and broader platforms rather than adding isolated tools. If Zscaler continues winning larger deals that bundle multiple products, that can support both growth and customer retention.
