SentinelOne, Inc. (S) primarily sells its cybersecurity platform and services to other companies, operating on a Business-to-Business (B2B) model. Its solutions are designed to protect "an organization's endpoints" and "cloud workloads."

However, SentinelOne serves a broad and diverse customer base that spans various industries and organization sizes globally. As stated in their public filings (e.g., 10-K reports), no single customer has represented 10% or more of their revenue in recent fiscal years. This indicates that the company does not have a concentration of revenue from a few "major customers" in the traditional sense.

Due to the diversified nature of its customer base and the confidential relationships often involved in cybersecurity services, SentinelOne does not publicly disclose a specific list of individual "major customer companies" with their stock symbols. Their clientele typically includes:

• Large enterprises
• Small and medium-sized businesses (SMBs)
• Government agencies
• Healthcare organizations
• Financial institutions
• Educational institutions

Therefore, a list of specific major customer company names and their symbols cannot be provided.

Key Business Risks for SentinelOne (S)

1. Intense Competition and Pricing Pressure: SentinelOne operates in a highly competitive cybersecurity market, facing established and larger rivals such as Microsoft, CrowdStrike, and Palo Alto Networks. Microsoft, in particular, often bundles security features with its other software offerings, creating "pricing gravity" that pressures SentinelOne to continuously demonstrate superior return on investment to justify its per-seat cost. This competitive landscape, where SentinelOne is an "emerging challenger" with a notable but smaller market share (approximately 9.47% of the endpoint protection market as of 2025), significantly impacts its outlook and growth prospects.

2. Challenges in Achieving Consistent Net Profitability: Despite demonstrating robust revenue growth and surpassing $1 billion in annual revenue for fiscal year 2026, SentinelOne has encountered significant profitability challenges. While the company achieved full-year operating profitability in fiscal 2026, it still reported a net loss of US$110.23 million in the latest quarter, indicating that consistent net income profitability remains an ongoing execution challenge. Financial analysis reveals a high gross margin but also substantial negative net and operating margins, highlighting persistent profitability issues.

3. Execution Risk Related to AI and Acquisitions: As a company heavily reliant on its AI-powered autonomous threat prevention, detection, and response capabilities, SentinelOne faces risks associated with its core technology, specifically "AI hallucinations." A scenario where the AI misidentifies legitimate system processes as threats or vice-versa could severely damage brand trust and product efficacy. Additionally, the integration of recent acquisitions, such as Prompt Security and Observo AI in 2025, presents complex execution risks. Any delays or issues in merging these technologies could lead to product bloat or customer churn. The company's platformization strategy also means that a failure in one part of its broad Singularity platform could jeopardize the entire customer relationship.

SentinelOne (NYSE: S) is expected to drive future revenue growth over the next 2-3 years through several key initiatives and market trends:

1. Expansion of the Singularity XDR Platform and Multi-Product Adoption: SentinelOne is focused on expanding the adoption of its comprehensive Singularity XDR platform, which integrates endpoint protection, endpoint detection and response, cloud workload protection, and IoT security. A significant driver is the increasing number of enterprise customers utilizing three or more platform modules, up from 39% to 65% in fiscal 2026. This indicates successful cross-selling and upselling within their existing customer base by offering a broader suite of security solutions. The company's non-endpoint solutions now represent approximately half of quarterly bookings, highlighting diversification beyond traditional endpoint security.
2. Growth in AI-Driven Security Products: The company is heavily investing in and seeing strong traction from its AI-driven security products. Specifically, Purple AI has achieved a record attach rate of over 50% on licenses sold in Q4 fiscal 2026, and its quarterly bookings have shown triple-digit year-over-year growth. Prompt Security's Annual Recurring Revenue (ARR) also more than doubled sequentially. SentinelOne positions itself as an "AI-native" cybersecurity platform, leveraging artificial intelligence as a core differentiator and growth engine.
3. Customer Expansion and Upmarket Momentum: SentinelOne continues to grow its customer base, particularly by securing larger enterprise clients and increasing its average revenue per customer. The number of customers with over $1 million in ARR increased by 20% annually to 153 in fiscal 2026, while customers contributing over $100,000 in ARR reached 1,667, representing 18% growth. This growth is fueled by both new customer acquisitions and deeper penetration within the existing installed base, leading to larger deal sizes and higher ARR per customer.
4. International Market Expansion: International markets are a significant and growing contributor to SentinelOne's revenue. In fiscal 2026, international markets expanded by 30% and accounted for 40% of total revenue, demonstrating strong global adoption of its cybersecurity offerings. This geographical expansion is expected to continue driving revenue growth as the company broadens its global footprint.
5. Expansion into New Security Domains: Beyond its core endpoint security, SentinelOne is expanding its offerings into new critical security domains, such as cloud security and data solutions (including AI SIEM). Cloud security ARR has surpassed $160 million, and data solutions have exceeded $100 million in ARR. The company has also introduced a unified cloud security suite that has gained strong traction, further diversifying its revenue streams and addressing evolving cybersecurity needs.
