Is FTNT better than TENB for value investing?

On the Buffett-style value-investing framework, FTNT currently grades higher — 83/100 vs 47/100, a 36-point gap. The gap is driven by which pillars each stock passes; the table on this page shows moat, durability, management, financial health, and valuation side-by-side.

What's the difference between FTNT and TENB on Warren Buffett's framework?

FTNT currently scores 83/100 (A grade); TENB scores 47/100 (D grade). The "Where each wins" section on this page breaks down which pillar each stock dominates.

Which has the stronger moat, FTNT or TENB?

Moat strength is one of the five pillars in the Buffett-Fit score on this page. FTNT and TENB are each scored on ROIC sustainability, gross-margin durability, and qualitative signals like brand strength, switching costs, network effects, and regulatory barriers. The pillar breakdown on this page shows the moat sub-score side-by-side so you can see which one has the more durable competitive advantage.

Which is more undervalued, FTNT or TENB?

Valuation is one of the five Buffett-Fit pillars on this page. Both stocks are scored on owner-earnings yield, price-to-intrinsic-value vs the underlying compounding rate, and the margin of safety relative to a conservative DCF. The valuation sub-score in the table below tells you which one currently trades at a more attractive price relative to its underlying business quality.

Are FTNT and TENB both Technology stocks?

Yes — both Fortinet, Inc. (FTNT) and Tenable Holdings, Inc. (TENB) operate in the Technology sector. That makes this a direct sector-peer comparison, which is the apples-to-apples way to use the Buffett-Fit framework: the score weighs each stock against its sector's specific quality and valuation benchmarks (sector-relative bonus), so the cross-stock comparison isn't distorted by inter-sector base-rate differences.

Is this FTNT vs TENB comparison investment advice?

No. This page is an educational pattern-match against documented public frameworks (Buffett, Graham, Fisher, Lynch, Greenblatt, Munger, Smith), not personalised investment advice. The scores reflect how closely each stock matches each framework's documented criteria — they are not buy/hold/sell recommendations. Always do your own research and consult a licensed financial adviser for personalised advice.
