Web App Security Testing as a Service (OWASP-Based): What You Get

Web application security testing as a service means a provider tests your app for common security weaknesses, using the OWASP guidance as the checklist, and reports each finding with a severity and a fix. You buy it before a launch, a customer security review or after a scare. It is application-level testing against recognised guidance; it is not a certified penetration test and produces no compliance attestation.

If you would rather have it tested for you, see how RAITHub would test this below, or start at the QA as a service overview. For the hands-on checklist, read the OWASP Top 10 testing checklist.

What is OWASP-based security testing as a service?

OWASP, the Open Worldwide Application Security Project, publishes the widely used reference for web application security risks. The OWASP Top 10 lists the most common and serious categories, and the Web Security Testing Guide sets out how to test for them. Security testing against this guidance checks your app for those weaknesses: broken access control, injection, misconfiguration and the rest.

"As a service" means a provider runs that testing for you: scanning to catch the obvious, then manual testing to find the logic flaws scanners miss, and reporting each finding with where it is, how serious it is and how to fix it. The most valuable findings are usually the authorisation flaws, such as one user being able to read another user's data, which sit at the top of the Top 10 and never show up in the UI.

What does an OWASP-based security testing service cover?

Area	What it answers	What you should receive
Access control	Can one user reach or change another user's data or admin functions?	Findings on broken object-level and function-level access
Authentication	Are login, sessions, password reset and tokens handled safely?	Findings on weak auth, session and token handling
Injection	Can crafted input reach a database or command?	Tests for SQL, command and cross-site scripting injection
Configuration	Are headers, errors, defaults and secrets set safely?	Misconfiguration findings, including exposed keys
Data exposure	Is sensitive data over-returned or poorly protected?	Findings on data leakage in responses and logs
Dependencies	Are known-vulnerable libraries in use?	A dependency review against known advisories

Scanners catch a slice of these, mostly configuration and known-vulnerable dependencies. The access-control and business-logic flaws, which cause the worst breaches, need a person who understands how the app is meant to work. That is why the service combines automated scanning with manual testing rather than relying on a scan alone.

What you receive, and what it is not

• A findings report: each issue, its OWASP category, its severity, where it occurs and how to fix it.
• A prioritised list, so the highest-risk issues are fixed first.
• A retest of the fixes, where that is in scope, confirming the issues are closed.

What it is not: a certified penetration test or a compliance attestation. This is application-level testing against OWASP guidance. If a customer contract, PCI DSS or an auditor requires a CREST- or PCI-accredited penetration test with a signed report, you need an accredited firm for that. The difference between testing types is covered in penetration testing vs vulnerability scanning. This is general information; confirm your specific obligations with your adviser.

When in a project do you need security testing?

• Before a public launch, especially once the app holds accounts, payments or personal data.
• Before or during a customer security review, where a buyer asks what testing you have done.
• After a scare or a near miss, to find out what else is exposed before someone else does.

Buy, build or hire?

Route	What you get	Choose this when	Watch out for
A tool or SaaS platform	An automated scanner or dependency checker	You want to catch obvious issues continuously in CI	Scanners miss access-control and logic flaws, the worst ones
Freelancers or crowdtesting	An individual tester or a bug-bounty crowd	A defined pass, or ongoing crowd coverage	Depth and coverage vary; reporting quality is uneven
An accredited pentest firm	A certified penetration test with a signed report	A contract, PCI DSS or auditor requires an accredited report	This is the only route that produces an attestation
A managed QAaaS team	OWASP-based testing with findings and fixes, you own	You want application-level security testing without hiring	It reports to OWASP guidance; it is not a certified pentest

Why RAITHub for OWASP-based security testing?

• Testers who build secure systems. Finding an access-control flaw takes someone who understands how authorisation is meant to work, which is what RAITHub's engineers build.
• Automated plus manual. Scans catch the obvious; manual testing finds the logic and access-control flaws that cause real breaches.
• Proven in its own builds. Sundor Skin ships a security suite that deliberately tries to read other buyers' data, with CI failing if a buyer-scoped table lacks row-level security; it runs 530+ tests. There is no standalone security-testing case study yet, so judge the service on a free audit.
• Everything stays yours. The report is yours, the IP is assigned to you, and an NDA is standard.

When don't you need this security testing service?

• When you need a CREST- or PCI-accredited penetration test with a signed attestation; use an accredited firm.
• When your team already runs OWASP-based testing and automated scanning and only needs a specific gap filled.
• When the product is pre-launch and still changing shape daily; test once the attack surface is stable.

How RAITHub would test this

• Scope: agree the app, roles and data in scope, with the OWASP Top 10 and the Web Security Testing Guide as the checklist.
• Test: automated scanning for the obvious, then manual testing of access control, authentication, injection, configuration and data exposure, plus a dependency review.
• Report: each finding with its OWASP category, severity, location and fix, prioritised so the highest risk is first.
• Retest: where in scope, a retest confirming the fixes close the findings.

Timeline: a security audit is fixed in scope and dates before it starts; it can also sit inside a monthly QA plan. You receive: the findings report mapped to OWASP guidance, a prioritised fix list and a retest where in scope, all yours, under an NDA as standard. Next step: a free 15-minute audit, then a written fixed quote. RAITHub publishes no rates, and this testing produces no certified-pentest or compliance attestation.

To start, request a one-off security audit. For the specialist page, see security testing; for a related compliance-adjacent audit, the accessibility audit service.

Frequently asked questions

What does OWASP-based security testing cover?

Testing your web app for the weaknesses in the OWASP Top 10 and Web Security Testing Guide: broken access control, authentication flaws, injection, misconfiguration, data exposure and known-vulnerable dependencies, each reported with a severity and a fix.

Is this a penetration test?

It is application-level security testing against OWASP guidance, which overlaps with a pentest but is not the same. It produces no certified report. If a contract or auditor requires a CREST- or PCI-accredited penetration test, you need an accredited firm for that.

Does it make us compliant with PCI DSS or any standard?

No. The service finds and helps you fix security issues, but it produces no compliance attestation. Confirm your specific obligations, such as PCI DSS requirements, with your adviser or the relevant auditor.

Can an automated scanner do this instead?

A scanner catches part of it, mostly configuration issues and known-vulnerable libraries. It misses access-control and business-logic flaws, which cause the worst breaches and need a person who understands the app, so the service combines both.

What is the most common serious finding?

Broken access control, where one user can read or change another user's data by changing an identifier in a request. It sits at the top of the OWASP Top 10 and is invisible from the user interface, so only deliberate testing finds it.

How much does web application security testing cost?

It depends on the size of the app, the number of roles and whether a retest is in scope. RAITHub publishes no rates and quotes a fixed price after a free 15-minute audit call.
