What's the difference between a bug bounty and a penetration test?
A penetration test is a time-boxed engagement where named senior testers methodically cover an agreed scope and hand you a report. A bug bounty is a standing invitation to a global crowd of researchers to find what they can, paid per valid bug. A pentest buys coverage and evidence; a bounty buys continuous opportunistic discovery. Mature programmes use both, in that order.
How do they compare side by side?
| Dimension | Bug bounty | Penetration test |
|---|---|---|
| Who tests | Anonymous global crowd, self-selecting | Named senior consultants under contract and NDA |
| Coverage | Unpredictable. Hunters go where the payouts are | Methodical. The agreed scope gets covered |
| Timing | Continuous, always on | Time-boxed: days to weeks, then a report |
| Cost model | Platform fees + per-bug rewards + internal triage effort | Fixed fee. E.g. AU$8,000–18,000 for a web application |
| Output | A stream of individual reports of wildly varying quality | Impact-ranked report, executive summary, attestation letter |
| Compliance value | Low. Auditors want a scoped test | High. The standard evidence for ISO 27001, SOC 2 and reviews |
| Operational load | High. Every submission needs triage | Low. Findings arrive validated and reproduced |
When should you choose which?
Sequence matters more than preference here.
Choose a penetration test when…
- The asset has never had professional adversarial testing. A bounty crowd will just invoice you for the obvious findings one duplicate at a time.
- You need an auditor-ready report for ISO 27001, SOC 2, PCI DSS or an enterprise customer review.
- You need guaranteed coverage of something specific: a new product, a major release, an AI feature.
Choose a bug bounty when…
- Your assets are already tested and hardened, and you want continuous eyes on what changes between engagements.
- You have (or can outsource) the triage capacity to handle the submission stream.
- Your attack surface is broad and public enough that crowd economics work in your favour.
How does Ironbark Cyber fit?
Ironbark Cyber sits on both sides of this fence with unusual credibility: founder Luke Stephens (hakluke) is a widely known bug bounty hunter, and the firm delivers senior-only penetration testing. Fixed quotes within one business day, findings ranked by real-world impact, free 90-day retest. So the recommendation is unconflicted: pentest first, always; add a bounty programme once the easy findings are gone and you can handle the stream. And if the stream is already drowning your engineers, our sister service Triagers.com does the deduplication, validation and researcher comms so they can get back to shipping fixes.
FAQ
Frequently asked questions
Is a bug bounty cheaper than a penetration test?
Not reliably. A pentest is a known, fixed cost. Ironbark Cyber publishes ranges like AU$8,000–18,000 for a web application. A bounty programme has platform fees, unpredictable reward payouts, and the ongoing internal cost of triaging every submission, valid or not. Bounties reward outcomes; pentests buy coverage. The budgets behave completely differently.
Does a bug bounty satisfy compliance requirements?
Usually not. ISO 27001, SOC 2 and enterprise security reviews expect a scoped, methodical penetration test with a report and attestation. A bounty programme is continuous and opportunistic. Valuable, but not the document your auditor is asking for.
Should we run a bug bounty before our first penetration test?
No. Launching a bounty on untested software is paying retail for bugs a pentest would have found wholesale. And your team will drown in duplicate reports. Test first, fix, then open a programme to catch what emerges over time.
Who does the testing in each model?
A pentest gives you named senior consultants under contract and NDA, with agreed scope and rules of engagement. A bounty crowd is anonymous, global and self-selecting. Enormous collective talent, no guarantee any of it looks at your asset this month. Ironbark Cyber's founder has spent years on both sides, as a bug bounty hunter and as a consultant.
Our VDP inbox is overflowing. Is that a pentest problem?
No. That's a triage problem, and it's common enough that Ironbark Cyber's sister service Triagers.com exists to solve it: deduplication, validation, severity rating and researcher comms, so your engineers only see real, actionable reports.
