How it works
How API Security Checklist works
Answer 8 questions
Complete a short questionnaire covering critical API security controls: authentication, rate limiting, input validation, HTTPS, error handling, versioning, logging, and CORS.
Get your security score
Your answers are scored across each API security domain to produce an overall security rating and per-area breakdown, highlighting exactly where your APIs are exposed.
Receive a hardening plan
Get a personalized vulnerability analysis with a prioritized API hardening plan, so you can fix the most critical security gaps first and reduce your attack surface.
Features
What API Security Checklist checks
Evaluate authentication and authorization
Assesses whether your APIs use modern auth standards like OAuth 2.0 with token rotation, or rely on weaker methods like static API keys — a leading cause of API breaches.
Check rate limiting and abuse prevention
Evaluates your rate limiting strategy to ensure per-user and per-endpoint throttling is in place to prevent brute force attacks, credential stuffing, and resource exhaustion.
Review input validation and injection prevention
Checks whether you enforce schema validation on all API inputs to prevent SQL injection, NoSQL injection, SSRF, and other injection attacks from the OWASP API Top 10.
Assess logging, monitoring, and CORS
Reviews your API request logging, anomaly detection, and CORS configuration — critical controls for detecting attacks in progress and preventing cross-origin abuse.
Score error handling and information leakage
Detects whether your API error responses leak stack traces, internal paths, or database details that attackers use for reconnaissance during targeted attacks.
Use cases
Who should use the free API Security Checklist
Backend Engineers
Quickly audit your API security controls against industry best practices. Identify gaps in authentication, validation, and error handling before they become vulnerabilities.
Security Engineers
Use as a lightweight pre-pentest checklist to assess API hardening. Prioritize which APIs need deeper testing and generate a remediation backlog for engineering teams.
Engineering Managers
Get visibility into your team's API security posture without deep technical expertise. Use the results to prioritize security work in your sprint planning and roadmap.
