Flexible hours: YES

Cybersecurity penetration testing as a side hustle typically offers flexibility in setting your own schedule. Most companies hiring for this role allow testers to choose when they perform assessments. Online discussions on platforms like Reddit and niche forums generally support the idea that this side hustle offers genuine flexibility. However, some testers have mentioned that there may be occasional time constraints based on client needs or project deadlines. Overall, the consensus seems to be that while cybersecurity penetration testing allows for setting your own hours, there may be times when flexibility is somewhat limited due to project demands.
