Both Bug Bounty and Pentesting focus on finding and addressing security vulnerabilities, but they differ in the number of testers involved, the reward models, and the testing frequency.

For instance, a Bug Bounty is an ongoing program involving a more extensive and diverse group of hackers with varying skills, and rewards are based on the severity of the vulnerability discovered. Penetration testing (pentesting for short), in contrast, is part of the hacker toolbox to infiltrate a system through the firewall to look for unsanitized inputs that are susceptible to attacks, but it’s typically conducted by a select few consultants on a one-time or periodic basis.
