What Should a 10-Person Cybersecurity Consulting Firm Actually Pay for Software?

A cybersecurity consulting firm's stack has a feature that shows up in almost no other industry we cover: two full vulnerability-scanning platforms and two full compliance-automation platforms sit in the same category on purpose, because different clients standardize on different tools. That's a defensible reason to have both in your vendor list. It is never a defensible reason to be paying for both at once for your own internal use — and that single decision, more than headcount, is what separates a $3,300/mo stack from one pushing $6,800/mo.

Here's what we actually see, tool by tool and pillar by pillar, for a firm around 10 people — typically a principal consultant, three or four pentesters or security engineers, a compliance/GRC analyst, someone writing and QA'ing reports, and a business-development or admin hire covering the rest.

Sales & Marketing: $505/mo — the one pillar that's basically fixed

Unlike scanning or compliance tooling, there's no real "choose one of two" decision here — at 10 employees, all three tools below fit comfortably inside their team-size range, and the pillar total doesn't really move until you're much bigger or much smaller.

HubSpot ($400/mo) is the biggest line item because it's doing double duty as CRM and engagement tracker — pipeline for new pentest and audit statements of work, plus renewal dates for retainer clients. The common mistake: treating it like a generic sales CRM with generic stages, so nobody gets an alert when a 12-month SOC 2 retainer is 60 days from renewal, and the firm finds out it lapsed when the client's auditor calls asking why evidence collection stopped. Mailchimp ($75/mo) sends CVE-advisory and compliance-deadline newsletters — cheap, and usually the first thing cut when trimming budget, which is backwards, since it's the lowest-cost-per-lead tool in the pillar and often the reason a lapsed client re-engages before a scanner even gets involved. Calendly ($30/mo) handles scoping calls and audit kickoffs; the failure mode here isn't cost, it's double-booking a pentester across two overlapping client engagements because nobody built buffer rules around active testing windows.

Core Operations: $1,905-3,255/mo — where the real decision lives

This pillar is 5-6x every other pillar combined, and it's the one where firms genuinely overpay — not because the tools are overpriced, but because two of the seven tools below are direct substitutes for two others, and a lot of firms run all four instead of picking one from each pair.

Tenable Nessus ($500/mo) and Qualys VMDR ($600/mo) are alternatives, not additions — both find unpatched systems and misconfigurations across client environments. Qualys costs more because it adds cloud-native continuous monitoring and detection/response, which is real value if you sell ongoing managed vulnerability retainers, and dead weight if you mostly sell one-time point-in-time assessments. The common mistake is licensing Qualys for a client base that only ever buys one-time engagements, then never downgrading. Burp Suite Professional ($185/mo) is the manual web-app pentest toolkit every tester needs a seat for; the failure mode is under-licensing seats for concurrent engagements, which either stalls a live test or pushes testers onto free tooling mid-engagement without telling the client. PlexTrac ($400/mo) is supposed to cut report-writing time by pulling scanner findings straight into client-ready reports — it only delivers that if it's actually wired up to Tenable/Qualys and Burp; firms that buy it and then keep copy-pasting findings from spreadsheets are paying $400/mo for a word processor. KnowBe4 ($120/mo) runs phishing simulations and awareness training the firm resells as a managed offering to clients — the mistake is treating it as an internal-only tool and forgetting to bill the client retainer that's supposed to cover it. Vanta ($750/mo) and Drata ($700/mo) are the second substitute pair: both automate SOC 2/ISO 27001/HIPAA evidence collection for client compliance engagements, and running both usually means a firm inherited one platform from an acquired book of clients and never consolidated.

Finance: $389/mo

QuickBooks Online Plus ($90/mo) runs the general ledger and reconciles project-based engagement billing; the common gap is not tracking work-in-progress on time-and-materials engagements, so revenue recognition lags what the team actually delivered that month. Gusto Plus ($200/mo) handles payroll for a small team of highly compensated consultants — the expensive mistake here is misclassifying a subcontracted specialist pentester (brought in for a niche skill like ICS/SCADA testing) as a 1099 when the work pattern actually meets employee criteria, which is a real audit exposure, not a theoretical one. Bill.com ($99/mo) automates approval and payment for tool subscriptions and subcontractor invoices; without a SOW reference attached to each subcontractor invoice, disputes over billable engagement scope become routine. Ramp is functionally free at this size and earns its keep through automatic receipt capture on client-site travel — travel that should often be rebilled to the client but gets absorbed as overhead when nobody tags it correctly.

Admin & Security: $430/mo

Google Workspace Business Standard ($170/mo) hosts email and documents hardened with 2FA for handling client vulnerability data — the irony of a security firm skipping org-wide 2FA enforcement on its own email is not lost on the auditors who eventually find it. 1Password Business ($95/mo) holds shared vaults for client VPN credentials and scanning-tool licenses; the failure mode isn't setup, it's teardown — vault access left active after an engagement ends is exactly the kind of dangling-credential finding this firm would flag in someone else's audit. Huntress Managed EDR ($85/mo) protects the firm's own laptops, which is easy to skip on the logic of "we're a security firm, we know what we're doing" — except those laptops routinely carry unreleased client vulnerability findings, making them a higher-value target than almost anything else in the building. DocuSign ($80/mo) gets rules-of-engagement, NDAs, and MSAs signed before testing starts; starting a scan or a pentest before the ROE is fully executed is an unauthorized-access exposure with no legal cover, and it happens when a scoping call runs long and someone decides to "just get started."

What this adds up to

Add it up and a genuinely optimized stack for a 10-person cybersecurity consulting firm lands at $3,229-3,379/mo, depending only on whether you pick Tenable or Qualys and Drata or Vanta. We regularly see firms paying $4,579-6,800/mo for the same functional coverage — and unlike a lot of industries, we can point to exactly where that gap comes from, because it isn't vague "enterprise tier" overpay, it's specific duplicate line items.

The fastest way to see where your specific stack lands against these numbers is to run the free audit — it uses your actual headcount and current spend, not a generic estimate.
