Web Application Security Certification

The Web Application Security Certification is a free intermediate-level, 20-minute skill test from Science of Apps. It tests professional web application security at practitioner level — browser security controls such as cookies, CSP, CORS and HSTS, authentication, sessions and OAuth, injection, SSRF and other server-side flaws, and API security, testing and secure delivery — written to the OWASP Top 10, OWASP API Security Top 10 (2023), the OWASP Web Security Testing Guide and Cheat Sheets, MDN Web Docs and RFC 9700 (OAuth 2.0 Security Best Current Practice) for 2026. Goes deeper than our Application Security Fundamentals test. Score 70% or more on its 20 questions to earn a verifiable Web Application Security Proficiency certificate (SOA-WAS). Every question is based on published standards and research — including OWASP Cheat Sheet Series (OWASP), OWASP Top 10 (OWASP), Using HTTP cookies (MDN Web Docs (Mozilla)) — and each answer is explained with its source.

Science of Apps offers a free Web Application Security Certification, updated for 2026 and 2027.

Yes. The questions are original scenarios written by Science of Apps, and each one is based on a public source you can read: OWASP Cheat Sheet Series (OWASP); OWASP Top 10 (OWASP); Using HTTP cookies (MDN Web Docs (Mozilla)); Content Security Policy (CSP) guide (MDN Web Docs (Mozilla)); RFC 9700: Best Current Practice for OAuth 2.0 Security (IETF); Web Security Testing Guide (OWASP). The source is shown under each question and linked in the answer review. Science of Apps doesn't copy questions from other tests.

Four skill areas with five questions each, drawn from a bank of 10 per area so a retake brings new questions: Browser Security Controls (Cookies, CSP and headers and CORS and same-origin policy); Authentication, Sessions and OAuth (Passwords, Session management and OAuth and tokens); Injection and Server-Side Flaws (Injection, SSRF and file handling and Access control); API Security, Testing and Secure Delivery (API risks, Testing and Secure SDLC). Every question is an original scenario written to the 2026–2027 standard, with the published source named under it.

Web or full-stack developer, Application security engineer, Penetration tester focused on web apps, DevSecOps engineer and Security-minded tech lead. It suits anyone who wants a quick, verifiable way to show Web Application Security knowledge in 2026 and 2027, from students and career switchers to experienced professionals.

Popular options include GIAC GWEB and GWAPT, Offensive Security's OSWE, PortSwigger's Burp Suite Certified Practitioner and (ISC)² CSSLP for secure development. They all expect solid knowledge of the OWASP risks, browser security controls and secure authentication, which this test checks.

Broken access control tops the OWASP Top 10: users can act outside their intended permissions, for example by changing an ID in a URL to read someone else's data. It is prevented with server-side, deny-by-default authorisation checks on every request.

Yes. The test is online, in English and free everywhere — people take it from India, the US, the UK, Europe, Africa, Latin America and Asia-Pacific. Your certificate is dated with your own local date and can be verified from anywhere at scienceofapps.com/certification/verify/.

You see your score for each area and every question with the correct answer and why, with the published source behind it. You can retake after 30 minutes, and the retake draws questions you haven't seen yet.

No. Every certificate is dated, so it always shows when you passed. Retake a test any time for a newer date or a higher score.

Yes. After you pass, Add to LinkedIn opens the Licenses & certifications form with the certificate name, Science of Apps as the issuer, the issue date, your credential ID and the verification link filled in. You can also download it as a PDF or PNG, and it's emailed to you as a PDF.

Every certificate has a credential ID and a QR code. Scanning it, or entering the ID at scienceofapps.com/certification/verify/, shows the holder's name, the certification, the score and the issue date from our records.

No. They are Science of Apps' own assessments of applied skill. They aren't issued by a university or standards body, and they work best alongside a portfolio that shows the skills in real work.
