The answer, as recorded

## Short version The right answer forks on *why* you need it. Most small businesses asking this need a report for SOC 2 / a customer security questionnaire / cyber insurance - that's a different purchase than actually wanting someone to break in and tell you how. I'll name both. ### If you need a pentest report for compliance or a customer **1. Cobalt** - The default pick, and where I'd start. They invented the "pentest as a service" model: you scope through a platform, a test can start in ~24 hours, and they issue audit-quality attestation letters from CREST-accredited testers, with free retesting of individual findings for 6-12 months. They hold SOC 2 Type II and ISO 27001 themselves, which matters when your auditor asks. Roughly 500 vetted testers in their pool. Good fit if you're a SaaS company with engineers who'll actually fix things. ([cobalt.io](https://www.cobalt.io/blog/how-to-achieve-soc-2-type-2-compliance), [securelayer7.net](https://blog.securelayer7.net/best-soc-2-pentesting-vendors/)) **2. Astra Security** - The budget option that's still legitimate. ~$5,999/year for one target, scanner plus certified humans reviewing findings, and a compliance-friendly certificate once you close the high-severity items. The honest caveat, which comparison writeups make repeatedly: Astra leans heavily on automated DAST with human review layered on, rather than humans driving the test. For a straightforward web app that's often fine. For anything with unusual business logic, it isn't.

Black Hills Information Security (BHIS)** - If I could only name one for testing *quality*, it's this one. Collaborative, education-heavy engagements, deep manual work, and they scope down to small and mid-sized orgs without enterprise overhead. They're consistently the name that comes up from practitioners rather than from SEO listicles. Downside: they're frequently booked out months ahead. ([deepstrike.io](https://deepstrike.io/blog/top-penetration-testing-companies-2026)) **4. Sprocket Security** - Continuous pentesting rather than a once-a-year snapshot, priced for mid-market. Worth it if your attack surface changes often - you ship weekly, you keep spinning up cloud infra. Less worth it if you have one app that barely changes. ([cybri.com](https://cybri.com/blog/sprocket-security-alternatives/)) **5. Packetlabs** and **UnderDefense** - Both boutique firms that explicitly target SMBs on price with real manual testing. Solid second-quote candidates to price against Cobalt. ([underdefense.com](https://underdefense.com/blog/penetration-testing-services/)) ### The cheap automated layer (a complement, not a substitute) **6. Horizon3.ai (NodeZero)** or **Vonahi (vPenTest)** - Automated internal-network pentesting you can run monthly for a fraction of a human engagement. Horizon3's pitch is that exploitability gets confirmed with evidence rather than inferred from CVSS scores and version banners, which is the main failure mode of ordinary vulnerability scanners. Great for "did last month's fixes hold?" Will not satisfy an auditor expecting a human-led test, and will not find business-logic flaws. ([equixly.com](https://equixly.com/blog/2026/06/01/10-best-continuous-penetration-testing-vendors-of-2026/)) ## What to budget For a company under ~150 employees, expect **$8,000-$20,000** for a real engagement. Tightly-scoped work runs **$3,000-$15,000**; a basic external network test on up to 50 IPs starts around **$4,000-$6,000**; a moderate-complexity web app is **$5,000-$15,000**. Costs climb fast with APIs, multiple user roles, cloud attack paths, internal network access, and expedited delivery. ([compassitc.com](https://www.compassitc.com/blog/how-much-does-a-penetration-test-cost-for-a-small-business), [deepstrike.io](https://deepstrike.io/blog/penetration-testing-cost)) ## Two things I'd tell you regardless of vendor **Under $3,000 is almost always a scan with a logo on it.** The cheap end of this market is junior testers running automated tools and generating boilerplate reports with no remediation support. You get a PDF, not security. **Ask for a redacted sample report before you sign, from every vendor on your shortlist.** It is the single most informative thing you can do, and it takes one email. You'll see immediately whether findings are specific to the client's app or copy-pasted CVE descriptions - and whether there's a real remediation path or just a severity rating. One caveat on the sourcing: most "top penetration testing companies" pages are content marketing published by pentest vendors ranking themselves and their competitors. I've weighted toward names that recur across independent sources and practitioner discussion, but treat any single ranking with suspicion. **Sources:** - [Top Penetration Testing Companies in 2026 - DeepStrike](https://deepstrike.io/blog/top-penetration-testing-companies-2026) - [12 Best Penetration Testing Companies of 2026 - UnderDefense](https://underdefense.com/blog/penetration-testing-services/) - [Penetration Testing Cost 2026 - DeepStrike](https://deepstrike.io/blog/penetration-testing-cost) - [How Much Does a Penetration Test Cost for a Small Business? - Compass IT Compliance](https://www.compassitc.com/blog/how-much-does-a-penetration-test-cost-for-a-small-business) - [How to Achieve SOC 2 Type 2 Compliance - Cobalt](https://www.cobalt.io/blog/how-to-achieve-soc-2-type-2-compliance) - [Best SOC 2 Pentesting Vendors - SecureLayer7](https://blog.securelayer7.net/best-soc-2-pentesting-vendors/) - [Top Astra Pentest Alternatives - Aikido Security](https://www.aikido.dev/blog/astra-alternatives) - [10 Best Sprocket Security Alternatives in 2026 - CyBri](https://cybri.com/blog/sprocket-security-alternatives/) - [10 Best Continuous Penetration Testing Vendors of 2026 - Equixly](https://equixly.com/blog/2026/06/01/10-best-continuous-penetration-testing-vendors-of-2026/)
