Risk: High

Starting a side hustle with an AI-Powered Security Vulnerability Scanner for Custom Code can be risky for beginners, especially those who can't afford to lose money. There is a potential to lose money invested in software development, marketing, and other operational costs. Beginners might also lose time and energy trying to learn the technology and navigate the cybersecurity market. While there is a possibility of not seeing returns on the initial investment, the startup costs for such a venture can be substantial and may not pay off if not managed effectively. Online discussions mention cases of beginners spending money on tools and resources without achieving profitable outcomes. I'd rate the risk a 1 out of 3 because there is a high chance of losing money, time, and energy if not careful.
