This document is a guide that outlines the pros and cons of four common penetration testing methods: traditional, crowdsourced, internal, and a mixed approach. It begins by describing traditional penetration testing, which typically involves one or two testers working within a defined timeframe. The guide then details crowdsourced security penetration testing, highlighting its rapid setup and potential for real-time results, while also noting its limitations. Internal security testing is discussed as a method preferred by larger organizations that can maintain in-house teams, allowing for customized testing schedules. Lastly, the mixed testing approach is presented as a combination of the other methods, suitable for sensitive projects but complex to manage. The guide also provides comparative data on the effectiveness and cost of these methods, indicating that crowdsourced testing often yields higher-quality results and identifies significantly more vulnerabilities than traditional methods. This information is intended to assist organizations in making informed decisions regarding their security testing strategies.
