5 Best Small-Cap Cybersecurity Stocks — Q2 2026
The small-cap cybersecurity universe is thinner than investors expect — the winners already scaled out. Here are the 5 highest-scoring names left, ranked on fundamentals for Q2 2026.
The small-cap cybersecurity universe has a problem investors rarely acknowledge: the best companies have already graduated out of it. CrowdStrike, Palo Alto Networks, Zscaler, Cloudflare, SentinelOne, Okta — every cyber name retail investors actually know is now mid- or large-cap. What's left below $2B market cap is a thinner universe of profitable niche players, mature incumbents in slow-growth mode, and one or two leveraged bets.
We scored every small-cap stock in our universe with cybersecurity-adjacent revenue. These are the 5 highest-scoring names for Q2 2026, ranked by our fundamental scoring model.
Why Small-Cap Cybersecurity Is Different
Four structural realities shape this sector:
- Winner-takes-most economics — cyber customers consolidate on platforms. Once a CISO picks CrowdStrike for endpoint, they rarely add a second vendor. Small-caps compete for what large platforms don't cover
- Consolidation pressure — M&A is constant. Many small-cap cyber names are essentially waiting to be acquired. Cisco, Thoma Bravo, and Palo Alto are the usual buyers
- Government customer concentration — several names here derive meaningful revenue from law enforcement, defense, or regulated financial services. Strong moats, lumpy deals
- Profitability over growth — unlike AI infrastructure where triple-digit growth is common, small-cap cyber is mostly single-digit growers that prioritize margins and buybacks
Our scoring rewards what actually works in this sector: gross margin, cash runway, debt discipline, and shareholder-friendly capital allocation. Revenue growth alone doesn't carry a small-cap cyber name the way it carries a biotech.

1. Cognyte Software (CGNT) — Score: 69.2 | Grade: SOLID
| Metric | Value | Score |
|---|---|---|
| Revenue Growth YoY | +11.9% | 19 |
| Gross Margin | 70.4% | 100 |
| Cash Runway | >36 months | 100 |
| Debt/Equity | 17.9 | 86 |
| P/S Ratio | 1.6x | 97 |
| Rule of 40 | 10.4 | 36 |
| Insider Ownership | 4.7% | 38 |
| 12m Dilution | +0.5% | 97 |
What drives the score: Cognyte spun out of Verint in 2021 and focuses on investigative analytics and counter-terror intelligence for governments and law enforcement. Double-digit revenue growth is the best in this peer set, gross margin is software-typical at 70%, and the P/S of 1.6x is the cheapest valuation of any name on the list. Clean balance sheet, minimal dilution.
Key risk: Near-zero insider ownership (4.7%) and thin operating margin (-1.5%) mean this is still a turnaround story — management needs to deliver on the profitability pivot, not just the growth.
2. Radware (RDWR) — Score: 69.0 | Grade: SOLID
| Metric | Value | Score |
|---|---|---|
| Revenue Growth YoY | +5.2% | 8 |
| Gross Margin | 80.6% | 100 |
| Cash Runway | >36 months | 100 |
| Debt/Equity | 5.8 | 95 |
| P/S Ratio | 3.6x | 84 |
| Rule of 40 | 3.8 | 26 |
| Insider Ownership | 11.5% | 68 |
| 12m Dilution | -31.1% | 100 |
What drives the score: Radware is the most shareholder-friendly name in this group by a wide margin — the 31% share count reduction over the past 12 months is one of the most aggressive buyback programs in the entire small-cap software universe. DDoS protection, WAF, and API security are durable recurring-revenue businesses. 80% gross margin, clean balance sheet, meaningful insider ownership at 11.5%.
Key risk: Single-digit revenue growth. Radware is a maturity play, not a growth play. If you believe the company is undervalued relative to its cash flows, the buybacks do the work. If you want top-line acceleration, look elsewhere.
3. OneSpan (OSPN) — Score: 66.5 | Grade: SOLID
| Metric | Value | Score |
|---|---|---|
| Revenue Growth YoY | 0.0% | 0 |
| Gross Margin | 73.8% | 100 |
| Cash Runway | >36 months | 100 |
| Debt/Equity | 2.3 | 98 |
| P/S Ratio | 1.7x | 97 |
| Rule of 40 | 20.6 | 51 |
| Insider Ownership | 2.4% | 19 |
| 12m Dilution | -10.5% | 100 |
What drives the score: OneSpan is the profitability outlier in this group — a 20.6% operating margin is the highest here. Authentication, digital signatures, and MFA for banking and financial services. The flat revenue reflects the transition away from legacy hardware authentication tokens (declining) toward SaaS (growing). Zero debt, share buybacks of 10%, P/S of 1.7x.
Key risk: Revenue growth is exactly 0% year-over-year. The company is profitable and returning capital, but the top line has stalled. Investors need to believe the SaaS mix-shift resumes growth, or accept this as a cash-return story.

4. Mitek Systems (MITK) — Score: 60.4 | Grade: SOLID
| Metric | Value | Score |
|---|---|---|
| Revenue Growth YoY | +4.4% | 7 |
| Gross Margin | 85.1% | 100 |
| Cash Runway | >36 months | 100 |
| Debt/Equity | 64.6 | 42 |
| P/S Ratio | 3.6x | 84 |
| Rule of 40 | 14.2 | 41 |
| Insider Ownership | 2.7% | 22 |
| 12m Dilution | -0.5% | 100 |
What drives the score: Mitek powers mobile check deposit for most major US banks (the MiSnap SDK is embedded in thousands of banking apps) and has extended into biometric identity verification. An 85% gross margin is the highest in this group — rare pure-software economics. Strong cash position ($154M against $663M market cap).
Key risk: Debt/equity at 64.6 is the weakest balance sheet sub-score here — the company has $155M in debt roughly matching its cash. Growth is slow. Low insider ownership at 2.7%. This is a steady, durable niche business without much near-term catalyst.
5. Rapid7 (RPD) — Score: 54.6 | Grade: SPECULATIVE
| Metric | Value | Score |
|---|---|---|
| Revenue Growth YoY | +1.9% | 3 |
| Gross Margin | 70.3% | 100 |
| Cash Runway | >36 months | 100 |
| Debt/Equity | 625.8 | 0 |
| P/S Ratio | 0.5x | 100 |
| Rule of 40 | 3.2 | 25 |
| Insider Ownership | 2.6% | 21 |
| 12m Dilution | +1.8% | 89 |
What drives the score: Rapid7 is the cheapest name on the list by a wide margin — P/S of 0.54x against $860M in TTM revenue. Vulnerability management (InsightVM), SIEM (InsightIDR), and MDR services are real platforms with meaningful customer traction. The low valuation earns a perfect P/S sub-score.
Key risk: Debt/equity of 626% is the reason this is a SPECULATIVE grade and not SOLID. Rapid7 has $968M in debt against negative stockholders' equity — the balance sheet is essentially inverted. Revenue growth of 1.9% is not enough to grow out of the leverage. This is either a deep-value turnaround or a distressed situation depending on your read of the recurring revenue quality.
What these stocks have in common
Looking across the 5 picks, four patterns emerge:
-
Gross margins are excellent. Every name on this list has a gross margin between 70% and 85%. That's the one place where small-cap cyber behaves exactly like its mid- and large-cap counterparts — software economics are software economics.
-
Growth is the weak spot. Only one name (Cognyte) is growing above 10%. Two are below 5%, one is exactly 0%. Investors looking at this sector need to accept that small-cap cyber is primarily a profitability and cash-flow story, not a growth story.
-
Capital returns are unusually strong. Radware's -31% dilution and OneSpan's -10% dilution are the kind of buyback programs you normally see in mature industrials, not in tech. Management teams in this group are explicitly returning capital rather than chasing growth that isn't there.
-
Valuations are compressed. Three of five trade below 2x sales. One (Rapid7) trades at 0.5x. For context, the average small-cap software P/S in our universe is closer to 6-8x. The market is pricing these as either value traps or distressed — the scoring model disagrees on some of them.
What's not on this list — and why
Tenable (TENB), Varonis (VRNS), CyberArk (CYBR), and Qualys (QLYS) are all cybersecurity names investors commonly search for at the small-cap level. None of them are in our universe anymore because all four have market caps above $2B. The same goes for SentinelOne, Cloudflare, Okta, CrowdStrike, and Palo Alto — the sector's historical winners have all graduated out.
This is the structural fact of small-cap cybersecurity: the sector exports its best companies upward. What remains is either (a) niche profitable operators, (b) mature incumbents in slow-growth mode, or (c) troubled names. The five above are the first two categories. Treat the sector accordingly.
How to use this data
These scores measure fundamental quality — not future stock price. A high score means the company's balance sheet, cash runway, margin profile, and capital allocation are strong relative to peers. It does not mean the stock will outperform.
For each name on this list, before deciding anything:
- Read the most recent 10-Q to confirm the numbers haven't changed since our last score update
- Check whether the company is currently in takeover rumor territory (small-cap cyber M&A is constant)
- For Rapid7 specifically, verify the debt stack and covenant status
- Understand the customer concentration — some of these names have meaningful government exposure that cuts both ways
SmallCapScanner scores are calculated algorithmically based on 8 fundamental factors. They measure financial health, not future performance. See /how-it-works for the full methodology.
