AquilaX API Security Scanner vs WuppieFuzz

AquilaX API Security Scanner analyzes API specifications and probes running endpoints for security weaknesses. Its checks target the OWASP API Security Top 10, including broken authentication, object-level authorization problems, mass assignment, excessive data exposure, and rate-limiting gaps. Supported inputs include OpenAPI 3.x, Swagger 2.0, GraphQL schemas, gRPC/Protobuf, Postman collections, discovered URLs, REST APIs, and webhook endpoints. The API scanner is available on Premium and Ultimate; all plans include unlimited scans without scan quotas or per-scan fees. AquilaX lists more than 50 integrations, including GitHub, GitLab, Jira, Slack, Azure DevOps, Bitbucket, and REST API access. CI/CD and IDE connections include GitHub Actions, GitLab CI, Jenkins, Azure Pipelines, CircleCI, Bitbucket Pipelines, TeamCity, VS Code, and JetBrains IDEs. On-premises deployment supports Docker and Docker Compose, air-gapped environments, Ubuntu 22.04 LTS or RHEL 9, and data sovereignty. AquilaX says source code is processed in isolated temporary environments, with only security findings retained and scan containers destroyed after analysis. It states that data in transit uses TLS 1.3 and stored findings and metadata use AES-256 encryption. Premium costs $19 a month per developer; Ultimate costs $99 a month per developer.

WuppieFuzz is a free, open-source, self-hosted REST API fuzzer built on LibAFL. It generates and mutates requests from an OpenAPI specification to seek potential errors and security flaws. Black-box, grey-box, and white-box testing are supported, along with authentication and input-validation testing. Authentication formats include Bearer, custom, cookie, OAuth, and Web Fuzzing Commons. Code coverage is supported for Java, JavaScript, and Python, while code coverage reports currently support JaCoCo. The tool can produce endpoint coverage reports, and a Grafana dashboard can visualize request information from a fuzzing campaign. It runs on Windows, macOS, and Linux and uses the Apache 2.0 license. TNO says fuzzing data is not shared with TNO or third parties. The tool is described for software development, supply-chain quality control, or penetration testing. WuppieFuzz requires an OpenAPI document in JSON or YAML to generate requests, and API discovery is not supported. Its plan costs nothing.
