Three approaches dominate application security testing: static analysis (SAST), dynamic testing (DAST) and manual penetration testing. They find different problems, and most teams need more than one.

How it works

SAST reads source code and flags risky patterns before the code runs. DAST tests the running application from outside and proves what is exploitable. Penetration testing is a human expert probing the application, usually once or twice a year.

SAST finds problems early but can be noisy and cannot see configuration. DAST sees the real deployed system but needs a running environment. Penetration tests are deep but infrequent and expensive.

Why it matters

• Use SAST in the IDE and pull requests to catch coding mistakes early.
• Use DAST on every build or release, and on a schedule, to catch what is exploitable at runtime.
• Use penetration testing periodically for business-logic flaws and chained attacks.
• Automated DAST between penetration tests keeps you covered all year.

Best practices

• Start with DAST if you can only pick one: it tests what attackers actually see.
• Feed DAST findings into your normal ticketing workflow.
• Share DAST reports with penetration testers so they can focus on deeper issues.

How Vooki Pro helps

• Gives you continuous DAST between penetration tests, on demand, scheduled or in CI/CD.
• Runs on your own machine, so there is no per-scan cloud cost and your scan data stays with you.
• Exports SARIF for code-scanning dashboards, alongside HTML, PDF, Word and JSON reports.
• Creates tickets in Jira, GitHub, GitLab, Linear or Azure DevOps from any finding.

Frequently asked questions

Is DAST better than SAST?

Neither replaces the other. SAST finds coding issues early; DAST proves what is exploitable in the running application.

Can DAST replace penetration testing?

DAST gives continuous automated coverage between penetration tests, but a human tester is still best for complex business-logic flaws.
