The scoring framework in full
How We Score Web Application Security Audit Firms
Eight criteria, each assessed from publicly available evidence: the firm's own service pages, published research or case studies, and — where a register exists — an independent accreditation database.
1. Methodology
The single biggest quality differentiator in this market is whether a firm tests manually or relies mainly on automated scanning dressed up as a penetration test report. A scanner catches known vulnerability signatures; it does not catch a broken authorization check between two user roles, because that is a logic flaw, not a signature match.
We look for explicit language about manual testing, business-logic review, and exploitation — not "comprehensive scanning", which is what a tool licence sounds like when it is being sold as a service. Alignment with the OWASP Web Security Testing Guide is a positive signal, because it is a published methodology a buyer can read rather than a proprietary one they must take on trust.
2. Accreditations
CREST and DESC, via Dubai's Cyber Force programme, are the two credentials UAE finance and government-adjacent buyers ask for most often. We check whether a firm's accreditation claim is current in the relevant public register, since marketing pages are sometimes not updated when a credential lapses or is renewed under a different corporate entity.
This criterion distinguishes three states, and the ranking table reports which one applies: the firm itself holds the accreditation; individual testers hold personal certifications but the firm is not registered; or neither is listed. The three are not interchangeable, and a regulator asking for an accredited supplier means the first.
3. Manual testing depth
Beyond "do they test manually", we look at how far that manual testing goes: authentication and session handling, API-specific testing, business-logic abuse cases, and whether the firm tests past the OWASP Top 10 checklist into application-specific attack paths.
The Top 10 is a risk-awareness document, not a test plan. A firm whose published scope stops exactly where that list stops is describing a baseline, and a multi-tenant application with a real authorization model needs more than a baseline.
4. Industry experience
A firm that has tested fintech applications repeatedly understands payment-flow abuse and regulatory reporting requirements in a way a generalist may not. We look for documented industry focus — named sectors, published case studies, sector-specific service pages — not a logo wall or a generic client list.
5. Report format
We look at whether a firm's published reporting approach includes proof-of-concept detail and CVSS scoring per finding, or delivers findings in a form that still requires the client's own team to interpret and prioritize them. A report that a developer can act on without a translation layer is worth materially more than one that lists severities against tool output.
Whether a redacted sample report is available before signing is part of this criterion. A firm confident in its reporting will show you one.
6. Delivery time
Stated turnaround from scoping to final report, since this drives planning around release schedules, compliance deadlines, and incident response timelines. A firm that will not commit to a turnaround in writing is a scheduling risk regardless of how good the testing is.
7. Remediation support
Whether a free retest is included after fixes ship, or billed as a new engagement. This materially affects total cost of ownership beyond the initial quote: an audit whose findings are never verified as fixed has produced a document, not a security outcome.
8. Public track record
Published research, CVE credits, case studies, or independent third-party coverage that can be checked against a source outside the firm's own marketing. This is the criterion most directly tied to how much a claim can be trusted rather than taken at face value, and it is the one where the difference between a firm that publishes original work and a firm that publishes blog posts becomes visible.
How the criteria are weighted
The eight criteria are not equal, because this page ranks firms for web application testing specifically rather than for security services in general. Weighting follows how much each criterion bears on that scope.
| Weight | Criteria | Why |
|---|---|---|
| Heaviest | Methodology, manual testing depth | They decide whether a business-logic flaw is found at all. Nothing else on the list compensates for a scan sold as a test. |
| Heavy | Accreditations, public track record | Both are independently checkable, which makes them the two criteria least susceptible to a firm's own marketing. |
| Moderate | Report format, remediation support | They determine whether findings become fixes, and they are where quoted prices diverge most from real cost. |
| Lighter | Industry experience, delivery time | Both matter to a specific buyer more than to the field. A fintech deadline changes their weight for you, not for the ranking. |
Weighting is applied consistently to all ten firms, including the firm ranked first. Because it is published here, you can re-weight it for your own situation — and apply the whole framework to a firm we have not covered.
What this framework does not measure
Price is not a scoring criterion. It says little about quality on its own and varies too much by scope to compare fairly across firms, so the ranking page carries market ranges by audit type instead of a price score.
Customer reviews are not scored either, since verified and independently checkable reviews are rare in this specific market segment. Nor is any assessment of these firms' actual technical output: we do not test them, and the editorial policy states that plainly rather than implying access we do not have.
Apply the framework yourself
The eight criteria turn into fifteen concrete questions you can put to any firm, whether or not it appears in this ranking.
