# Penetration Test vs Bug Bounty: Paid Days or Paid Findings?

> A penetration test is a fixed project: named testers, a defined scope, a few weeks, a report that also tells you what was tested and found clean. A bug bounty is a standing invitation to independent researchers to report vulnerabilities in your public systems for a reward per valid finding; it never ends, covers only what researchers feel like looking at, and needs a triage team behind it. Pentests fit products, internal systems and audit evidence. Bounties fit mature public services with a disclosure process already in place. Zyberum runs pentests and does not operate bug bounty programmes.

A pentest buys tester time with a fixed scope and a full report. A bug bounty pays independent researchers per valid finding, with no end date. When each pays off.

## What is the difference?

A penetration test buys time: a team of named testers works through a defined scope for an agreed number of days and writes a report that covers every finding and every area that was tested. A bug bounty buys results: you publish rules and rewards, independent researchers around the world look at your public systems whenever they want, and you pay for each valid, new vulnerability they report. One is a project with a start, an end and a known price. The other is a programme with a start, no end and a price that depends on how many bugs you have and how many people look.

The difference that matters most is coverage. A pentest report tells you what was tested, including the parts where nothing was found. A bug bounty tells you only what someone found. Nobody is paid to tell you that your password reset is fine, so nobody checks it systematically; everyone is paid to find the one thing that is wrong, so popular, easy-to-reach targets get a lot of attention and the rest gets little or none.

## Side by side

| | Penetration test | Bug bounty |
|---|---|---|
| What it covers | The whole agreed scope, including internal systems, firmware, hardware, source code and anything behind a VPN | Whatever researchers choose to look at within the published scope; in practice public web, API and mobile targets |
| What it misses | Anything outside the scope and the booked days; new code after the test | Systematic coverage, internal and pre-release systems, hardware, anything that needs physical access or a test vehicle |
| Who does it | A contracted team under NDA with written authorisation | Anonymous or pseudonymous researchers under the programme rules, usually via a platform |
| Duration | One to three weeks per target, then a retest | Continuous; programmes run for years |
| Typical cost | 6,000 to 15,000 euros for a web application, 15,000 to 30,000 for an IoT product; typical ranges for Germany and the EU, not an offer | Rewards from a few hundred euros per low to five figures per critical finding, platform fees from several thousand euros a year, plus your own triage time |
| Frequency | Once or twice a year and after major changes | Always on, with spikes after launches and public attention |
| Required by | PCI DSS, TISAX, OEM requirements, CRA conformity evidence, customer contracts | Nobody; CRA Annex I Part II requires a coordinated vulnerability disclosure policy, not a reward programme |
| Output | Report with reproduction, context, severity, fixes and a list of tested areas; a debrief | Individual reports of varying quality that your team has to triage, deduplicate, verify and reward |

## Choose a penetration test when

- The target is not public: an internal application, a pre-release product, an ECU, a machine, firmware, a cloud account. Researchers cannot reach it and would not be allowed to.
- You need evidence. A customer, an OEM, an auditor or a conformity assessment asks for a report with scope, date and tester, which a bounty cannot produce.
- You have no triage process yet. A bounty programme without someone who answers reports within days, verifies them and pays fairly damages your reputation faster than it finds bugs.
- You want depth on a specific area: authorisation across roles, a payment flow, a protocol implementation, a crypto design. A pentester spends days on it; a researcher moves on after an hour without a hit.

## Choose a bug bounty when

- You run a large public service that changes weekly. A yearly pentest cannot keep up, and the number of eyes a programme attracts is something no single team can match.
- You already have a disclosure policy, a security.txt, a vulnerability-handling process along the lines of ISO/IEC 30111 and a team that fixes within weeks. The bounty then adds motivation and legal clarity for researchers who would have looked anyway.
- You have had several pentests, the obvious issues are gone, and you want to find out what a wider and more creative crowd still sees.
- Your product is software that people can download and inspect at home, such as a mobile app with a public backend.

In these cases a bounty is the better choice: it gives you continuous attention on exactly the systems attackers also target, and a pentest cannot do that.

## Both together

Mature organisations do both: a pentest for every new system and major release, and a bounty on the public estate in between. The order matters. Start with a disclosure policy and a security.txt (RFC 9116), so that researchers who find something have a legal, non-paid route; in Germany § 202c StGB makes that clarity valuable for both sides. Then pentest until the report comes back short. Only then open a paid programme, private first with a handful of invited researchers, public later. Launching a public bounty on an untested application means paying a reward for every finding a pentest would have delivered for a fixed price.

Zyberum does penetration tests and helps manufacturers set up vulnerability-handling and disclosure processes, for example for the CRA. We do not operate bug bounty programmes and do not act as a platform. If your situation calls for a bounty, we say so and help you prepare the scope, the triage criteria and the fixes, so that the programme pays for findings and not for your homework.

## FAQ

**Is a bug bounty cheaper than a penetration test?**

Sometimes per finding, rarely overall. Rewards for valid findings typically run from a few hundred euros for a low to five figures for a critical one, plus platform fees or your own triage staff, and the costs never stop. A pentest of a web application costs 6,000 to 15,000 euros once, typical ranges for Germany and the EU. If a bounty turns out cheap, it is usually because few researchers looked.

**Can a bug bounty replace the pentest my customer or auditor asks for?**

Usually not. Auditors, OEMs and frameworks such as PCI DSS or TISAX ask for a test with a defined scope, a date, a named tester and a report that covers the whole system. A bounty gives you a stream of reports about whatever researchers happened to examine; it cannot prove that something was tested and found clean.

**Does the Cyber Resilience Act require a bug bounty?**

No. Annex I Part II of Regulation (EU) 2024/2847 requires manufacturers to have a coordinated vulnerability disclosure policy and a contact for reports, and to handle and fix vulnerabilities. A disclosure policy with a security.txt and a working inbox satisfies that; paying rewards is optional.
