The verdict in three sentences
A web application pentest in New York costs between 10,000 and 35,000 USD in 2026 for a mid-sized company, meaning 3 to 10 days of testing billed at 2,500 to 3,500 USD per day. The most useful format to reassure an enterprise buyer is grey-box testing (the tester gets user accounts), covering the OWASP Top 10 and followed by a retest at 2,000 to 5,000 USD. A firm holding CREST accreditation or able to support SOC 2 evidence costs 15 to 25% more, but its report is accepted without debate by bank and Fortune 500 security teams.
What a pentest costs by scope
Pricing is built on person-days. The number of user roles, business screens and API endpoints drives duration. Here are 2026 ballpark figures in New York.
| Scope | Approach | Test days | Price (USD) | Typical use |
|---|---|---|---|---|
| Marketing site + form | Black box | 2 - 3 | 6,000 - 9,000 | Baseline check |
| Simple SaaS app (2 roles) | Grey box | 3 - 5 | 10,000 - 16,000 | Customer security questionnaire |
| Business app + REST API | Grey box | 5 - 8 | 16,000 - 26,000 | Enterprise procurement |
| Multi-tenant platform + mobile app | Grey box | 8 - 10 | 25,000 - 35,000 | Contract with sensitive data |
| Targeted code review | White box | 4 - 8 | 14,000 - 28,000 | Critical functions (payments, permissions) |
| Fix retest | Per report | 1 - 2 | 2,000 - 5,000 | Remediation proof |
Also plan 1 to 2 internal days to prepare test accounts, a staging environment and written authorisation.
What an OWASP Top 10 pentest checks
The OWASP Top 10 (2021 edition, 2025 revision being adopted) is the common grid. Enterprise buyers expect the report to rank each vulnerability by severity (CVSS score) with a fix recommendation.
| OWASP category | Concrete example | Frequency in mid-sized firms | Indicative fix cost (USD) |
|---|---|---|---|
| A01 Broken access control | Seeing another client's invoices by changing an ID | Very common | 3,000 - 10,000 |
| A02 Cryptographic failures | MD5 passwords, TLS 1.0 enabled | Common | 1,500 - 6,000 |
| A03 Injection | SQL injection in a search filter | Medium | 2,000 - 8,000 |
| A05 Security misconfiguration | Missing CSP headers, exposed admin console | Very common | 1,000 - 4,000 |
| A07 Authentication failures | No rate limiting, no MFA | Common | 3,000 - 9,000 |
| A06 Vulnerable components | Outdated JavaScript libraries | Very common | 2,000 - 12,000 |
In practice, a first pentest of a mid-sized company finds 8 to 20 vulnerabilities, 1 to 4 of them critical or high. Budget remediation at 50 to 100% of the audit price.
Accredited firm, freelancer or bug bounty: which provider
In the US there is no state qualification equivalent to France's PASSI, so buyers look at CREST accreditation, OSCP or OSWE certified testers and the provider's ability to feed SOC 2 and NYDFS Part 500 evidence (mandatory for financial services licensed in New York). An independent OSCP-certified pentester charges 1,500 to 2,200 USD per day and suits a first assessment. Bug bounty (HackerOne, Bugcrowd) complements a pentest but does not replace it: it produces no compliance report.

Rachel, CISO of an HR software vendor in New York (70 employees), must provide a pentest report to a bank that wants to roll the tool out to 5,000 employees, a 420,000 USD a year contract. The 7-day grey-box pentest by a CREST firm costs 24,500 USD, internal fixes take 12 developer days at 900 USD, so 10,800 USD, and the retest 4,000 USD. Total: 39,300 USD, about 9.4% of the first contract year. Without the report, the bank refused to sign. Compared with an average US breach cost above 9 million USD, the spend is marginal.
FAQ
What is the difference between a vulnerability scan and a pentest?
An automated scan (200 to 1,000 USD a month) finds known flaws but does not test business logic. A manual pentest finds access control flaws, which account for nearly 40% of critical vulnerabilities in mid-sized firms.
How often should a pentest be repeated?
At least once a year and after every major redesign. Many enterprise vendor questionnaires require a report less than 12 months old.
Can production be tested directly?
Yes, with written authorisation and a defined window, but an identical staging environment is preferable. It avoids disruption and often costs under 300 USD a month to run.
Is a pentest report enough for SOC 2?
It is strong evidence for the security criteria but not sufficient alone. A SOC 2 Type II audit adds 30,000 to 80,000 USD and a 6 to 12 month observation window.
How long until I get the report?
Allow 2 to 4 weeks between order and testing, then 5 to 10 business days for the final report.
