OWASP Top 10 Testing — Find and Fix the Most Critical Web App Risks
The OWASP Top 10 is the most widely referenced list of critical web application security risks. Customers, auditors and frameworks such as PCI DSS and ISO 27001 use it as the baseline a secure web application is expected to meet.
The 2025 edition keeps Broken Access Control at number one and adds two new categories: Software Supply Chain Failures and Mishandling of Exceptional Conditions. Mutex Systems tests your applications against every category manually, not just with a scanner.

Core Domains
A Practical Engagement Path
- 01
Scope & threat model
Agree roles, user journeys and business logic to test, and how the application handles money, data or access.
- 02
Automated + manual testing
Scanners find the obvious; manual testing finds access-control and logic flaws that scanners miss.
- 03
Report by category
Every finding mapped to its OWASP Top 10 category, with severity, evidence and a fix.
- 04
Free retest
We retest fixed issues and issue a clean retest report for customers and auditors.
Manual testing against every category
Most serious web breaches come from broken access control and business-logic flaws that automated scanners cannot see. We test them by hand.
- Authenticated testing for every user role
- Supply-chain review of dependencies and build pipeline
- Mapping to PCI DSS 6.2.4 and ISO 27001 8.28
Continuous OWASP coverage between tests
grComply’s Security Posture module runs code and web application scans between pen tests and keeps every OWASP finding visible until it is fixed.
- Findings from code, web app, API, cloud, Kubernetes and network scans in one findings list
- Each finding mapped to its technical benchmark and to the controls of every framework you hold
- High-risk findings raised straight into the risk register with an owner and due date
- Retest results recorded as evidence, so auditors see the fix, not just the finding
grComply is Mutex Systems' own multi-tenant GRC automation platform — the framework library, hybrid scanning, risk and audit workflow, and AI-assisted compliance behind every point above are live in production today.

What changed in the OWASP Top 10 2025?
Two new categories — Software Supply Chain Failures and Mishandling of Exceptional Conditions — were added, Broken Access Control stayed at number one, and several categories were renamed or merged. It is the first major revision since 2021.
Is the OWASP Top 10 a compliance standard?
No, it is an awareness document. But PCI DSS, many customer contracts and auditors expect web applications to be protected against it, so testing against it is a common requirement.
Is an automated scan enough for OWASP Top 10?
No. Scanners catch some injection and misconfiguration issues, but access-control and business-logic flaws — the top risk — need manual testing.
Should we use the OWASP Top 10 or ASVS?
Use the Top 10 for awareness and as a minimum test baseline; use ASVS when you need a detailed, testable requirement set for development or verification.
