The verdict in three sentences
In 2026 in Singapore, a black-box penetration test of a web application ranges from USD 8,000 to USD 18,000, while a full audit with an OWASP report runs USD 12,000 to USD 30,000, verification retest included. The typical turnaround is 1 to 3 weeks depending on scope, and remediation generally represents 20 to 40 % of the audit cost. An annual pentest is now the baseline expected by enterprise clients and cyber insurers.
How much a pentest costs in Singapore in 2026
Price depends mostly on the test type and the knowledge given to the auditor. Here are 2026 orders of magnitude for a mid-sized web app (around thirty screens, one API).
| Test type | Knowledge provided | 2026 cost (USD) | Timeline |
|---|---|---|---|
| Black-box | None (external attacker) | 8,000 - 12,000 | 1-2 weeks |
| Grey-box | User accounts provided | 12,000 - 18,000 | 2 weeks |
| White-box | Source code + architecture | 18,000 - 30,000 | 2-3 weeks |
| Full audit + OWASP | White-box + detailed report | 12,000 - 30,000 | 2-3 weeks |
| Verification retest | Re-check of fixes | Included - 3,000 | 3-5 days |
The cost per senior auditor-day sits between USD 1,200 and USD 2,000/day in 2026; a typical engagement consumes 6 to 15 person-days depending on depth.
What the scope and deliverables cover
A serious scope tests all 10 OWASP categories and documents each flaw with an exploitable proof.
| Scope item | Included | Price impact |
|---|---|---|
| Injection (SQL, NoSQL, command) | Yes | Base |
| Authentication & session management | Yes | Base |
| Access control (IDOR, privileges) | Yes | +10-20 % |
| REST / GraphQL API | Scope-dependent | +15-25 % |
| Business logic | Yes (grey/white) | +20 % |
| CVSS report + remediation plan | Yes | Base |
| Retest after fixes | Yes | Included |
| Attestation for client/insurer | Yes | Base |
The core deliverable is a prioritised report (critical / high / medium / low severity), with proof of concept, business impact and a concrete recommendation per vulnerability, plus an attestation usable in pre-sales.

Mini case study
Nizar, CTO of a SaaS SME in Singapore (32 people), must reassure a banking client before signing a USD 240,000/year contract. He commissions a grey-box audit at USD 16,000 (10 days), which reveals 3 high findings (including an IDOR on invoices) and 6 medium ones. Remediation takes his team 8 person-days (~USD 5,000 internal), then the included retest validates the fixes. Total security spend: ~USD 21,000, less than 9 % of the annual value of the contract won thanks to the attestation. Immediate ROI.
FAQ
How often should a pentest be repeated? At least once a year, and after every major change (new sensitive feature, auth redesign). Cyber insurers and enterprise clients often require an attestation less than 12 months old.
Black-box or white-box: which to choose? Grey-box offers the best value in 2026 (USD 12,000-18,000): the auditor has accounts and covers more business logic than black-box, without the cost of a full code review.
Is the retest really included? With a serious provider, yes: a retest of fixed vulnerabilities is part of the engagement, usually within 3 to 5 days after you deliver your fixes. Require it in writing in the quote.
How much should I budget for remediation? Count 20 to 40 % of the audit cost depending on the number and severity of flaws. For a USD 16,000 audit, plan USD 3,000 to 6,500 in fixes, internal or outsourced.
Does a pentest guarantee zero flaws? No. It gives a point-in-time snapshot of risk and a prioritised roadmap. Security is a continuous process: monitoring, patching and an annual pentest remain essential.
