What is OWASP?

OWASP maintains open resources such as the OWASP Top 10 (web application risks), the API Security Top 10, the LLM Top 10 for AI applications, and testing guides.

These lists are references, not regulations, but they are widely adopted as a baseline for secure development and testing.

Who does OWASP apply to?

Development, security, and testing teams building or assessing web applications, APIs, and AI/LLM applications.

Key security expectations

  • Address the current OWASP Top 10 categories of application risk.
  • Cover API-specific risks with the OWASP API Security Top 10.
  • For AI applications, address the OWASP LLM Top 10 risks such as prompt injection.
  • Use OWASP testing guidance as part of secure development and assessment.

How an assessment works

  1. 1
    Scope the application, API, or AI system.
  2. 2
    Test against the relevant OWASP Top 10 and testing guide.
  3. 3
    Validate findings manually to confirm real, exploitable issues.
  4. 4
    Report with severity, evidence, and remediation guidance.
