Passive income: NO

Earning passive income solely from Cybersecurity Penetration Testing as a side hustle is unlikely for most individuals. While it is possible to automate certain aspects of the testing process or outsource some tasks, consistent passive income is rare in this field. Most penetration testers rely on active client engagements for income rather than passive sources. Setting up automation tools and establishing efficient workflows can help streamline operations, but ongoing monitoring and updates are typically required. While some outliers may achieve passive income through specialized services or products related to penetration testing, the majority of practitioners earn actively from their services.
