Intruder's API Scanner by Intruder is a comprehensive tool designed to identify and fix weaknesses in APIs before they can be exploited. It performs automated vulnerability scanning for APIs or web services, mimicking a remote attacker's actions to find vulnerabilities such as information disclosure, injection issues, broken authentication, and misconfigurations. The API Scanner can look for vulnerabilities behind logins if credentials are provided. It scales API vulnerability scanning to meet the needs of growing businesses, ensuring continuous protection against unauthorized access and data breaches. The scanner supports authenticated or unauthenticated scans using the OpenAPI or Swagger protocols. Users can upload their API schema to initiate automated security scans, which are essential for preventing service disruption and data breaches. The API Scanner integrates into DevOps processes, allowing security checks to be performed earlier in the development lifecycle. It provides comprehensive reports to demonstrate security and includes proactive threat response to check APIs for emerging threats, with intelligent prioritization of results and remediation advice. The scanner is available across all Intruder plans (Essential, Pro, Premium, and Vanguard).
