On forward P/E, Tenable Holdings, Inc. is actually cheaper at 11. 1x — notably different from the trailing picture, reflecting expected earnings growth. The PEG ratio (P/E divided by earnings growth rate) is the most growth-adjusted single valuation metric: Qualys, Inc. wins at 0. 66x versus Radware Ltd.

For long-horizon retirement investors, Qualys, Inc.

(QLYS) is the stronger choice — it scores higher on the combination of lower volatility, dividend reliability, and long-term compounding (low volatility (β 0. 53), +267. 2% 10Y return). SailPoint, Inc. (SAIL) carries a higher beta of 1. 81 — meaning larger drawdowns in market downturns, which matters significantly when you cannot wait years for a recovery. Both have compounded well over 10 years (QLYS: +267. 2%, SAIL: -44. 6%), confirming both are viable long-term holds — but the lower-volatility option typically results in less emotional selling during corrections. Retirement portfolios generally favour predictability over maximum returns. Consult a financial advisor before making allocation decisions.

Both stocks operate in the Technology sector, making this a peer-level intra-sector comparison — the same macro tailwinds and headwinds will affect both.

In terms of investment character: RDWR is a small-cap quality compounder stock; QLYS is a small-cap deep-value stock; TENB is a small-cap quality compounder stock; VRNS is a small-cap quality compounder stock; SAIL is a small-cap high-growth stock. These fundamental differences mean investors should not choose between them on a single metric — the "better stock" depends entirely on which of these characteristics aligns with your investment strategy.
