S vs TENB Stock Comparison: AI Score, Valuation, Performance and Upside
S and TENB are both mid-cap cybersecurity companies facing the same consolidation pressure from different categories. SentinelOne sells endpoint detection and response, growing faster but not consistently profitable and competing directly with larger rivals. Tenable sells vulnerability and exposure management, growing more slowly with a stronger margin profile, a long-established installed base, and a lower valuation.
Use this S vs TENB comparison to assess which category better resists bundling. Endpoint security is a large, strategically important budget line but also the one Microsoft attacks most directly. Vulnerability management is less contested by Microsoft but more easily absorbed into broader platforms as a feature rather than a product.
TENB holds the edge across 3 of 5 key metrics in this comparison. S has delivered stronger 1-year price return (+23.03% vs +13.26%), though TENB has the better forward P/E setup (15.67x vs 42.15x for S). On fundamentals, S is growing revenue faster (20.60%), while TENB maintains the higher operating margin (4.85%) — a classic growth-versus-profitability split. Analyst consensus implies meaningfully more upside for S (+22.69%) than for TENB (+3.24%).
