Mario Luck, founder of Ceron. I charge from $1,500 for a fixed-fee security audit, which makes me something of an outlier, so let me show you the entire pricing landscape: what things really cost, why, and how to tell when a number is honest. Every figure below is defensible. If a vendor quotes you outside these ranges, this article tells you what question to ask.
The short answer
If you just want numbers, here they are. The ranges below are what I have seen across the market for a typical small to mid-size SaaS company: one web app, one or two cloud accounts, under 50 employees.
Automated scanner subscriptions run $50 to $500 per month. You get headers, known CVEs, and common injection patterns, checked continuously. You do not get business logic testing, because a subscription scanner cannot understand what your product does.
AI-driven autonomous scanning platforms run $1,000 to $10,000 or more per year. Coverage is still scanner-class, but the tooling and triage are better. Prices vary wildly because the category is young and vendor maturity varies even more.
Compliance-focused pentests, the kind your SOC 2 or ISO 27001 auditor requires, run $8,000 to $25,000. What you are buying is a report that satisfies your auditor. Testing depth varies inversely with price pressure, and at the low end it can be thin.
A traditional external penetration test from a consultancy runs $10,000 to $30,000. Manual testing, days to weeks of work, one point in time. Add internal or authenticated scope and you are looking at $15,000 to $60,000 or more, because each access level multiplies the testable surface.
A fixed-fee audit from a solo practitioner runs $1,500 to $8,000. One operator, defined scope, verified findings. This is the category I compete in, and I will come back to why it exists.
A red team engagement runs $25,000 to $100,000 or more. Objective-based adversary simulation. This is not what a 20 person startup needs, and I will say why later.
Two caveats before you use any of these numbers. First, geography and brand move prices: a Big Four consultancy will quote 3x to 10x a boutique for comparable technical work, and sometimes that buys you a logo your enterprise customer's procurement team recognizes, which is a legitimate reason to pay it. Second, everything above is point-in-time testing except the scanner subscriptions. If your product changes monthly, a $20,000 annual pentest is testing a product that no longer exists for eleven months of the year.
Where the money actually goes
Prices in security testing are not arbitrary. They decompose into four cost centers, and knowing them lets you audit any quote.
Sales and overhead (20 to 40 percent at consultancies). A firm with account executives, proposal writers, and a marketing budget loads all of it into your engagement. This is the biggest single reason identical technical work costs $8,000 from a solo practitioner and $25,000 from a consultancy. You are not paying for better testing. You are paying for the machine that sold it to you. Sometimes worth it (enterprise procurement, compliance optics), often not.
Testing hours (the real product). Manual security testing by someone competent runs $100 to $250 per hour in Western markets. A serious external pentest of one web app is roughly 40 to 80 hours of focused work: reconnaissance, mapping, auth testing, business logic probing, exploitation attempts, verification, false-positive elimination. Do the arithmetic and the $10,000 to $20,000 range explains itself. Quotes dramatically below that range mean fewer hours, cheaper hours, or automated output with a human cover sheet.
Verification and reporting (where cheap engagements quietly fail). Finding something suspicious is 20 percent of the work. Proving it is exploitable, ruling out false positives, writing evidence an engineer can act on, and ordering fixes by real business impact is the other 80 percent. This is the labor that gets cut first under price pressure, and it is the labor you are actually buying. A report full of unverified "potential issues" transfers the cost back to your engineering team, which is more expensive than the audit.
Tooling and infrastructure (small but real). Proxies, scanners, cloud accounts for testing, lab environments. A few hundred dollars per engagement. Anyone itemizing this heavily is padding.
Why the same audit costs $1,500 from me and $15,000 from a firm
Honest answer, since this article is useless without it. Three structural differences:
AI methodology. I run frontier AI models with custom harnesses against your attack surface to investigate configuration, permissions, and exposed services, and I verify every candidate finding manually before it enters a report. The models do breadth; I do judgment. This compresses reconnaissance and hypothesis generation, which is a large slice of traditional testing hours. It does not replace the practitioner. An AI that reports a "critical vulnerability" without evidence has done nothing; verification is the job, and verification is human.
Fixed fee, no findings no fee. I quote one price before testing, and you pay only if I find a verified, actionable vulnerability in scope. This transfers risk from you to me, which means I only take engagements where I genuinely expect to find something, and I test accordingly. A firm billing hourly cannot offer this without abandoning its business model.
The catch, stated plainly: a solo practitioner is one person. If you need a team on site for two weeks, a red team, or a brand your Fortune 500 customer's procurement department recognizes, you need a firm, and you should pay firm prices. The $1,500 to $8,000 band serves startups and SMBs whose alternative is often no testing at all.
What drives your specific number
Any vendor quoting before understanding these four variables is quoting a template:
Assets. How many applications, APIs, domains, and services? One marketing site plus one app plus one API is a very different engagement from twelve microservices. Roughly, each additional authenticated application adds 30 to 100 percent to manual testing effort, depending on complexity.
Environments. One cloud account or four? A single AWS account with clean IAM is a day of configuration review. Multi-account, multi-cloud, Kubernetes in the mix: a week or more.
Access depth. Unauthenticated external testing is the cheapest and finds the least. Authenticated testing with two or more test accounts at different privilege levels is where the serious findings live (broken access control, the most exploited API vulnerability class, is invisible without it). Internal network testing costs more again. Each access level you authorize multiplies the testable surface.
Complexity and integrations. SSO, multi-tenancy, payment flows, third-party integrations, legacy components. A multi-tenant SaaS with Stripe billing and OAuth has more trust boundaries than a brochure site, and trust boundaries are where vulnerabilities concentrate.
A useful sanity rule: price tracks your attack surface, not your headcount. A 5 person team running 30 microservices needs more testing than a 200 person company with one monolith. Any quote that scales with employee count is pricing you as a logo, not as an environment.
How to read a quote: five questions
How many testing hours does this include? If they cannot or will not say, the number is small.
What is excluded? A scope section without an exclusions section is a scope section in hiding.
Is this manual testing or automated scanning with a report wrapper? The tell: ask what happened the last time their tool flagged a false positive. Manual testers have stories. Wrapper vendors get defensive.
Does the report include evidence and prioritized remediation, or a findings list? "Here are 34 issues, CVSS scored" without reproduction steps and fix guidance dumps the expensive work on your team.
What happens if nothing is found? This question separates the confident from the rest. If the answer is "that has never happened," they are either extraordinary or inflating findings. If the answer is "you still pay," that is a legitimate business model, but know that you are buying effort, not outcomes.
When each option is the right call
A scanner subscription makes sense when you ship continuously and want cheap regression coverage on headers and known CVEs between real assessments. It is a smoke alarm, not a building inspection.
A compliance pentest makes sense when your SOC 2 auditor requires one. Buy it to spec, but understand you are buying a certificate. If your budget allows only one real assessment a year, make it count, and question five above applies hardest here.
A traditional pentest firm makes sense when you are enterprise-adjacent, procurement demands brand names, or you need a team for large scope. Real value, real prices.
A fixed-fee practitioner makes sense when you are a startup or SMB that needs one honest, verified assessment of a defined attack surface without five figures of spend, and you want the vendor's incentives aligned with finding truth rather than billing hours.
A red team makes sense when you have mature security, a detection function worth testing, and a budget to match. Almost nobody under 100 employees should be there yet.
The number that matters most
Whatever you spend, the audit is only as good as the fixes it produces. A $1,500 assessment whose High finding gets patched next sprint beats a $25,000 report that lives unread in a shared drive. Before you buy anything, ask yourself who on your team will own remediation, and pick a vendor whose report format that person can actually execute against: evidence, impact, and fix in priority order.
That is the whole market in one paragraph. The numbers above are yours to use; if a quote you receive contradicts them, you now know which question to ask.
