What is Bug Bounty Program?

Bug bounty programs crowdsource security testing to a global community of researchers, often run through platforms like HackerOne or Bugcrowd. Researchers test within a defined scope and rules of engagement, submit vulnerabilities through a responsible-disclosure process, and are paid based on severity and impact. This gives organizations continuous, diverse adversarial testing that complements their internal security efforts.

It differs from a penetration test: a pentest is a time-boxed engagement by a specific team with a fixed cost, while a bounty is ongoing, pay-per-valid-finding, and draws on many researchers with varied skills, so it surfaces issues an internal team or single pentest might miss. It also differs from internal QA, which focuses on functional correctness; bounties target security specifically. Mature programs use all three, internal testing, periodic pentests, and a bounty program, as layers.

For QA, the connection is the intake and handling: triaging incoming reports, reproducing and validating reported vulnerabilities, assessing severity, and feeding fixes and regression tests back into the process so the same class of bug does not recur. A well-run program needs clear scope, fast triage, fair rewards, and a smooth disclosure process to keep researchers engaged.
