There is no official "OWASP Top 10 certification" issued by the OWASP Foundation itself — OWASP is a nonprofit that publishes an awareness document, not a certifying body, so any credential claiming to certify you on the Top 10 comes from a third-party training provider. Understanding this distinction matters, because job descriptions and vendor marketing throw the phrase around as if a single accredited exam exists. It does not. What does exist are training courses, developer credentials, and organizational practices that demonstrate OWASP Top 10 competence, and those are worth pursuing.
What the OWASP Top 10 actually is
The OWASP Top 10 is a periodically updated awareness document listing the most critical web application security risks, ranked by prevalence and impact using data gathered from the security community. The list is a starting point for AppSec awareness, not a complete standard. The most recent revision was published in 2021 and reorganized the categories around root causes; a 2025 refresh has been in development. Current top categories include Broken Access Control, Cryptographic Failures, and Injection.
Because it is a document, "getting certified in the OWASP Top 10" really means demonstrating you can identify, exploit-in-testing, and remediate the risks it describes. That competence is provable in several ways.
Training and credentials that cover the Top 10
Several respected certifications teach and test the material even though "OWASP Top 10" is not their title:
- OWASP's own training resources — the WebGoat deliberately vulnerable application and the Application Security Verification Standard (ASVS) — are free and map directly to the risks. Working through WebGoat is the single best hands-on introduction.
- The SANS/GIAC GWEB (GIAC Certified Web Application Defender) covers secure coding against exactly these risk classes and is a recognized formal credential.
- The OffSec OSWA and OSWE focus on the offensive side — finding and exploiting web vulnerabilities, most of which live in the Top 10.
- Vendor developer courses from training platforms often issue a completion certificate specifically branded around the OWASP Top 10. These prove you took a course; they are not accredited exams, so weigh them accordingly.
If a role asks for "OWASP Top 10 certification," any of these — or a demonstrable portfolio of secure-coding work — satisfies the real intent behind the request.
How to actually learn the material
Certificates follow competence, not the reverse. A practical study path:
- Read the current OWASP Top 10 document end to end, including the linked cheat sheets for each category.
- Install WebGoat or a similar deliberately vulnerable app locally in Docker and work through each vulnerability class hands-on.
- Practice remediation in the language you actually ship, writing the vulnerable and fixed versions of each pattern.
- Learn the tooling — a static analyzer to catch these bugs at commit time and a dynamic scanner to find them in a running app. Our Academy walks through several of these categories with runnable examples.
The hands-on step is what separates people who can recite the list from people who can find and fix the bugs. Interviewers can tell the difference in minutes.
Demonstrating Top 10 coverage as an organization
For a company, "OWASP Top 10 coverage" usually shows up as a compliance or customer-security-questionnaire requirement rather than an individual credential. You demonstrate it with process and evidence, not a certificate on the wall:
- A secure SDLC that maps controls to each Top 10 category — access-control tests, dependency scanning, input validation standards.
- Tooling in CI — a SAST tool catching injection and access-control patterns, a DAST scanner probing the running app, and a software composition analysis tool such as Safeguard covering the "Vulnerable and Outdated Components" category by tracking known CVEs in your dependencies.
- Testing evidence — periodic penetration tests scoped explicitly to the Top 10, with findings tracked to remediation.
When an auditor or enterprise customer asks whether you "cover the OWASP Top 10," this body of evidence is the honest answer, and it is far more meaningful than any single person's certificate.
Watch for the "Vulnerable and Outdated Components" gap
One Top 10 category catches teams off guard because it is not about code they wrote: A06, Vulnerable and Outdated Components. You can write perfectly secure application logic and still ship a critical vulnerability inherited from a dependency you never audited. Covering this category means maintaining a software bill of materials, scanning dependencies continuously, and having a process to patch or replace flagged components quickly. Training that only teaches you to write safe code misses this entirely, which is why organizational coverage matters alongside individual skill.
FAQ
Does OWASP offer an official certification exam?
No. The OWASP Foundation publishes documentation, tools, and standards but does not run a certification program for the Top 10. Any credential using the name comes from a third-party training provider. OWASP does maintain the ASVS and testing guides, which are the closest thing to an official competence framework.
Which certification best proves OWASP Top 10 knowledge?
For defenders, the GIAC GWEB is a strong recognized option. For offensive testing, OffSec's OSWA and OSWE cover the material through hands-on exploitation. For a free, hands-on start, OWASP's own WebGoat plus the ASVS teach the concepts directly. The best choice depends on whether your role is building, breaking, or defending.
Is a vendor "OWASP Top 10 certificate" worth anything?
It proves you completed a specific course, which has value for onboarding and awareness, but it is not an accredited exam. Treat it as evidence of training rather than tested competence. Pair it with hands-on practice you can demonstrate, and it becomes credible.
How often does the OWASP Top 10 change?
Roughly every three to four years. The 2021 edition reorganized categories around root causes and was the current published version for several years, with a further revision in development into 2025. Because it lags emerging risks by design — it is built on collected historical data — treat it as a baseline rather than the leading edge of AppSec.
