Frequently asked questions
APIs require different security approaches, different techniques, and different security knowledge than traditional web applications. Ensuring that APIs are suitably secured and covered with robust, API-specific vulnerability scanning should be a key priority for any organisation that operates a modern web presence. AppCheck has been developed by expert penetration testers to assess APIs intelligently in the same context-aware manner as a penetration tester would and using the same methodologies.
Yes, AppCheck provides comprehensive scanning capabilities for APIs, web applications, and infrastructure, allowing you to identify vulnerabilities across your entire digital environment.
Automated, continuous scanning is recommended to catch vulnerabilities as early as possible. Regular scans can be conducted during development, pre-production, and after any changes or updates.
Yes, the AppCheck API scanner supports a variety of API types, including REST and SOAP, to ensure comprehensive security coverage.
How does API Vulnerability Scanning work?
Web API scanners such as AppCheck work by checking your APIs for common pitfalls and security issues that could be prone to attack. Rather than use a database of static signatures of known weaknesses, the AppCheck platform applies a rigorous test methodology to tease out even previously unknown weaknesses in the same way a hacker or penetration tester would.
AppCheck does this by using schema definitions and other gathered intelligence to build an internal reference model of the API that can then be used to leverage advanced heuristic testing techniques. This methodology of building up custom and specific test cases for each API from “first principles” reveals security issues within your API that scanners using static or legacy testing techniques simply cannot uncover. AppCheck provides suggestions for how any discovered vulnerabilities can be solved, based on best practice guidance from organisations including OWASP and MITRE, as well as in-house experts.
