How much does it cost to manage a bug bounty programme: in-house vs outsourced
By Kike Gandia · Co-Founder & CEO, OSCP
The cost of a bug bounty programme has two main components: the bounty cost (the rewards paid to researchers) and the management cost (the work of triaging, validating and coordinating reports). Many companies know the first number well but underestimate the second.
The bounty cost: what you pay researchers
Reward ranges vary enormously depending on the sector, programme size and vulnerability severity. Indicative ranges for programmes in Spain and Europe:
- Critical (CVSS 9.0-10.0): €2,000 - €20,000+ per vulnerability.
- High (CVSS 7.0-8.9): €500 - €5,000 per vulnerability.
- Medium (CVSS 4.0-6.9): €100 - €1,000 per vulnerability.
- Low (CVSS <4.0): €50 - €200 per vulnerability.
An active programme at a medium-sized company can pay between €10,000 and €100,000 annually in bounties, depending on the volume of valid findings.
The in-house management cost: what does not appear on the invoice
Managing a bug bounty programme internally involves:
- Security analyst time: an active programme may require between 40 and 80 hours per month of triage work, researcher communication and reporting. At a cost of €50-80/hour for a senior analyst, that is €2,000-€6,400 per month in time alone.
- Tools and platform: HackerOne or Bugcrowd charge between €5,000 and €30,000 annually for platform access and management tools (not counting managed triage).
- Training and context: the analyst needs to know your technical environment well to triage correctly. That learning curve has a cost.
Total in-house management cost: €30,000 - €100,000+ annually for an active programme.
The outsourced management cost: what it includes and what it does not
A typical external bug bounty management service includes:
- Full triage of all reports.
- Researcher communication.
- Technical vulnerability validation.
- Monthly reporting.
- Integration with your tools.
The cost depends on report volume and SLA level. For a programme with 20-50 reports per month, the indicative range is €1,500-€5,000 per month. Bounties are not included — they remain a client cost.
Compared with in-house management, the external cost is typically 30%-60% lower, not counting the cost of hiring and retaining a specialised analyst.
Bug bounty ROI: how to justify it to management
The ROI of a bug bounty programme is calculated by comparing the programme cost with the potential cost of a security breach.
Arguments for the management presentation:
• A data breach in Spain costs an average of €4.5 million (IBM Cost of a Data Breach 2024).
• The cost of a well-managed bug bounty programme is a fraction of that.
• A bug bounty acts as insurance: you pay to find the vulnerabilities before the attackers do.
• It is cheaper to pay a researcher €5,000 for a critical vulnerability than to manage it after an incident.
FAQ
Which is more expensive: HackerOne/Bugcrowd or an independent external management service?
The large platforms (HackerOne, Bugcrowd) charge for platform access and, if you contract managed triage, add an extra 20-40%. An independent management provider can be cheaper because it does not charge for platform access and can operate on tools you already have.
Can I have a bug bounty without a platform?
Yes. You can manage a bug bounty programme with your own channel (web form, email) without needing a third-party platform. The platform adds researcher community, management tools and visibility, but it has a cost. For private programmes with specific researchers, an in-house channel may be sufficient.
What should the minimum budget be for a bug bounty?
For a private programme with 5-10 invited researchers and a limited scope, a minimum budget of €5,000-€10,000 annually in bounties is a reasonable starting point. For a public programme, a minimum of €20,000-€30,000 annually in bounties plus the management cost is recommended.
