HackerOne
Largest bug bounty + VDP platform — quote-based, programs typically run $5K+/mo plus bounty pool.
What it does well
- Access to a very large and diverse community of security researchers.
- Provides managed services for triaging and validating submitted vulnerability reports.
- Offers structured programs for VDP, bug bounties, and compliance-focused pentesting.
Where it falls short
- Pricing is quote-based and opaque, with no public tiers or self-service signup.
- Total cost is unpredictable, as it includes both platform fees and variable bounty payouts.
- Not suitable for small businesses or those with limited security budgets.
