OWASP Top 10 Testing Services
We check your web app, mobile app and APIs against every OWASP Top 10 risk. You get a clear report: what is vulnerable, how bad it is and how to fix it. Then we turn the checks into automated tests, so the same holes do not come back in the next release.
Why test against the OWASP Top 10
The OWASP Top 10 is the industry’s shared list of the most critical web application security risks. Clients, auditors and security questionnaires ask for it by name. Testing against it gives you a standard, explainable baseline: you know which risk classes are covered, and you can show it.
Most breaches do not need exotic exploits. They come from broken access rules, misconfigured servers, weak authentication and unvalidated input, which is exactly what the Top 10 describes.
What we test: all 10 categories
| # | Risk | What we check |
|---|---|---|
| A01 | Broken Access Control | Users reaching data or actions they should not: IDOR, privilege escalation, missing authorization on API endpoints |
| A02 | Security Misconfiguration | Default settings, verbose errors, open admin panels, missing security headers, cloud and CORS settings |
| A03 | Software Supply Chain Failures | Vulnerable and outdated dependencies, untrusted packages, build and CI/CD pipeline risks |
| A04 | Cryptographic Failures | Data sent or stored without proper encryption, weak algorithms, exposed secrets |
| A05 | Injection | SQL, NoSQL, command and template injection, cross-site scripting (XSS) |
| A06 | Insecure Design | Business-logic flaws: skipping payment steps, abusing limits, unsafe workflows |
| A07 | Authentication Failures | Weak passwords and sessions, missing MFA, brute force, token handling |
| A08 | Software or Data Integrity Failures | Unsigned updates, insecure deserialization, tampering with trusted data |
| A09 | Security Logging and Alerting Failures | Attacks that leave no trace or trigger no alert |
| A10 | Mishandling of Exceptional Conditions | Errors and edge cases that leak data or leave the app in an unsafe state |
How an OWASP Top 10 assessment works
-
Scope
We agree on the apps, environments and user roles to test. Testing runs on staging unless you ask otherwise.
-
Automated scan
DAST and dependency scanners find the obvious issues fast.
-
Manual testing
Engineers test access control, business logic and authentication, the risks scanners miss.
-
Report
Every finding has a severity, steps to reproduce, the OWASP category and a fix recommendation.
-
Retest
After your fixes, we verify each issue is closed.
-
Automate
Key security checks become part of your regression suite and CI/CD pipeline.
Web, mobile and API coverage
Web applications
The full Top 10 across all user roles.
APIs
REST and GraphQL: authorization on every endpoint, input validation, rate limits.
Mobile apps
The app’s backend APIs plus data storage and transport on the device.
AI features
If your product uses an LLM, we also test prompt injection and data leaks. See AI testing.
What you get
- A prioritized vulnerability report your developers can act on
- OWASP category mapping for every finding (useful for security questionnaires)
- Retest results after fixes
- Automated security checks in your pipeline, written with our in-house approach in your team’s language

FAQ
What is OWASP Top 10 testing?
It is security testing of an application against the ten most critical web application risks published by OWASP, such as broken access control, injection and security misconfiguration.
Is OWASP Top 10 testing the same as a penetration test?
No. A penetration test simulates a real attacker with an open scope. OWASP Top 10 testing is a structured check of known risk categories. It is faster, more repeatable and a good first step; we can extend it into deeper testing if needed.
Can OWASP checks be automated?
Partly. Scanners and automated tests catch misconfigurations, known vulnerable dependencies and many injection issues. Access control and business-logic flaws need manual testing. We combine both and automate what can be automated.
Do you test APIs and mobile apps?
Yes. We test web apps, REST and GraphQL APIs, and mobile app backends and data handling.
How long does an assessment take?
It depends on the size of the app and the number of user roles. The free audit gives you a first report in 48 hours and an estimate for a full assessment.
Will testing break our production system?
We test on staging by default. Production testing is only done with your approval and agreed limits.
