The verdict in three sentences

Before go-live, a client requirement or a cyber insurance policy, your business app or SaaS must pass a security audit: 6,000 to 18,000 EUR for a code audit, 8,000 to 25,000 EUR for a pentest, retest included, in 2 to 4 weeks. The reference is OWASP ASVS, with a remediation contract. Set against the risk it is marginal: a GDPR fine can reach 4% of annual revenue.

One-off audit or recurring pentest: what do you actually need?

A one-off audit is perfect for a first go-live or a contractual requirement. As soon as you ship continuously (SaaS, monthly releases), a recurring pentest plus a bug bounty plan keeps the level over time.

CriterionOne-off auditRecurring pentest
2026 cost6,000 to 25,000 EUR12,000 to 40,000 EUR/year
FrequencyOnce (before prod)2 to 4 times/year
Retest includedYesYes, each cycle
Best forMVP, one-off requirementSaaS, frequent releases
CoverageFixed scopeEvolving
Complementary bug bountyOptionalRecommended

The right reflex: an initial audit to start clean, then a pentest 2 to 4 times/year once the product lives and evolves.

2026 price grid and methodology

Price depends on scope (roles, APIs, journeys) and depth (black, grey or white box). Here are the typical services.

Service2026 range (EUR)Timeline
Code audit (static review)6,000 to 18,0001 to 3 weeks
Black/grey box pentest8,000 to 25,0002 to 4 weeks
Cloud architecture audit5,000 to 15,0001 to 2 weeks
Retest after remediationIncluded3 to 5 days
Guided remediation plan4,000 to 12,000Depends on findings
Bug bounty program (setup)3,000 to 10,0001 to 2 weeks

Our methodology relies on OWASP ASVS (levels 1 to 3) and the Top 10, with EU-based data hosting, a report prioritized by criticality (CVSS) and a remediation contract guaranteeing the retest. Frame: these ranges are a 2026 order of magnitude depending on real scope.

Mini case study

Thomas is CISO of a SaaS vendor: a major account demands a pentest before signing a contract worth 180,000 EUR/year. Without proof of security, the deal is stuck. He orders a grey box pentest at 16,000 EUR, retest included, delivered in 3 weeks.

Two critical vulnerabilities are fixed before prod. The contract is signed: the pentest is less than 9% of the first year of secured revenue. Against that, a data leak would expose him to a GDPR fine of up to 4% of revenue and the loss of the account: the pentest is the cheapest insurance in the file.

FAQ

How much does a web app pentest cost in 2026?

Between 8,000 and 25,000 EUR for a black or grey box pentest, retest included. A code audit alone runs between 6,000 and 18,000 EUR depending on the number of roles and APIs.

What's the difference between a code audit and a pentest?

The code audit reads source code to find flaws at the root; the pentest attacks the app in real conditions. Both are complementary: code for depth, pentest for exploitation reality.

Is the retest included in the price?

Yes: we include a retest after your fixes to verify the vulnerabilities are truly closed, usually within 3 to 5 days.

Which framework do you use?

We follow OWASP ASVS (levels 1 to 3) and the Top 10, with a report prioritized by CVSS criticality and a guided remediation plan.

What's the risk without an audit?

An exploited flaw means service downtime, a lost contract and, in case of a data leak, a GDPR fine of up to 4% of annual revenue. The audit costs a fraction of that risk.
