A joint advisory from U.S. and international security agencies warning of Russian state-sponsored cyber threats to critical infrastructure has pushed cybersecurity stocks, including SentinelOne (S), into sharper focus for investors.

Beyond the immediate reaction to the cyber advisory, SentinelOne’s share price has shown building momentum, with a 30 day share price return of 28.90% and a year to date share price return of 33.74%, although the 5 year total shareholder return of 58.43% remains weak.

After SentinelOne’s sharp recent gains, the stock now sits at a very different entry point. The real issue is whether the current valuation still leaves enough upside potential to justify the risks.

Most Popular Narrative: 2% Overvalued

SentinelOne last closed at $19.58, slightly above the most followed narrative fair value of about $19.15. This frames the current move after the cyber advisory as only a modest premium to that assessment.

Expansion beyond endpoint security into high-demand adjacent markets such as cloud security, identity, and data protection, including the Prompt Security acquisition for GenAI risk, unlocks significant cross-sell opportunities and is expected to elevate average contract value and diversify revenue streams, laying the groundwork for outsized multi-year revenue growth.

Curious what justifies paying close to $20 a share for an unprofitable cybersecurity stock? This narrative leans on brisk revenue expansion, a sharp margin shift, and a premium future earnings multiple usually reserved for sector leaders.

Result: Fair Value of $19.15 (OVERVALUED)

However, SentinelOne’s reliance on large partners, along with the risk that acquisitions pressure margins before contributing meaningfully to revenue, could both undermine this upbeat narrative.

Another View on SentinelOne’s Valuation

While the popular narrative pegs SentinelOne as about 2% overvalued around $19.15, the SWS DCF model points the other way, suggesting a fair value closer to $27.73, or roughly 29% above the current $19.58 price. Which set of assumptions do you find more realistic?
