What is Bug Bounty?

What it does

A bug bounty platform connects an organization's attack surface with a pool of independent security researchers. Researchers probe targets, such as web applications, mobile apps, APIs, smart contracts, and infrastructure, then submit vulnerability reports through the platform. The platform handles:

• Triage and validation: Confirming that a reported issue is real, reproducible, and in scope before it reaches the internal team.
• Reward management: Calculating and paying bounties based on severity, often using a CVSS score or a custom severity rubric.
• Vulnerability Disclosure Programs (VDPs): Structured channels for researchers to report bugs without a cash reward, satisfying regulatory and policy requirements.
• Program scoping: Defining which assets are in scope, what vulnerability classes are accepted, and what the reward range is.

Some platforms also offer managed services where platform staff handle first-line triage, reducing noise for internal teams. Certain platforms focus on specific domains, such as blockchain smart contracts or AI and generative model vulnerabilities.

Why teams buy it

Internal security teams have limited time and perspective. A bug bounty program adds continuous, external testing from researchers with varied skill sets. Key reasons organizations adopt these platforms:

• Penetration testing engagements are point-in-time. Bug bounty programs run continuously.
• Researchers only get paid when they find valid bugs, so cost scales with results.
• A public VDP is increasingly required by frameworks such as ISO 27001 and by government mandates.
• Crowdsourced testing covers a wider range of attack techniques than a single internal team or a small pentest crew.
