Bug bounty or red teaming? That’s the wrong question
This question comes up frequently in practice. It’s a fair one, but it’s often based on a misunderstanding. Red Teaming and Bug Bounty serve different purposes. Treating them as alternatives means overlooking a critical part of the risk.
Bug Bounty vs Red Teaming: Two different approaches
Both Red Teaming and Bug Bounty are forms of offensive security testing, but they differ in their purpose.
Red Teaming simulates targeted attacks across people, processes and technology. A small team attempts to gain access to systems based on clearly defined objectives, typically across multiple steps. The focus is not only on identifying vulnerabilities, but also on assessing the organisation’s ability to detect and respond to attacks.
Bug Bounty programs, on the other hand, rely on continuous, exploratory testing by external security researchers. The goal is to uncover as many real-world vulnerabilities as possible, regardless of whether they are part of a predefined attack scenario.
In short:
- Red Teaming asks: Can we detect and respond to an attack?
- Bug Bounty asks: What vulnerabilities exist in the first place?
Key differences at a glance
| Dimension | Red Teaming | Bug Bounty |
|---|---|---|
| Objective | Simulating realistic, targeted attack scenarios | Identifying real, exploitable vulnerabilities |
| Timeframe | Limited (e.g. weeks) | Continuous |
| Scope | Clearly defined, scenario-based | Clearly defined, exploratory within defined scope |
| Approach | Scenario-driven, threat-led | Exploratory, attacker-driven |
| Perspective | Small expert team | External researchers with diverse specialisations |
| Outcome | End-to-end attack chain incl. detection & response assessment | Verified findings with reproduction steps and recommendations |
| Focus | Detection & response capabilities | Visibility and prioritisation of vulnerabilities |
Strengths and limitations
Red Teaming is particularly strong when it comes to:
- testing detection and response capabilities
- simulating attack paths
- validating organisational processes under pressure
- testing human and organisational factors (e.g. social engineering)
At the same time, it remains a snapshot in time. What is tested today may already be outdated tomorrow, especially in dynamic IT environments. New systems, changes, or previously undiscovered vulnerabilities often remain outside the scope.
Bug Bounty programs are most effective when:
- systems are continuously evolving
- multiple technologies are in use
- unexpected vulnerabilities need to be discovered
- findings can be efficiently triaged and remediated
However, they do not provide a full attack narrative. Individual findings must be prioritised and contextualised internally.
When to use Red Teaming vs. Bug Bounty
The key question is not either or, but when each approach delivers the most value.
Red Teaming is particularly suitable when:
detection and response processes need to be validated
specific attack scenarios are the focus
human, technical, and organisational controls need to be tested together
Bug Bounty is most effective when:
the attack surface is large and dynamic
continuous visibility of vulnerabilities is required
external perspectives are intentionally leveraged
Both approaches complement each other when:
continuous vulnerability discovery is combined with periodic validation
not only vulnerabilities, but also their potential exploitation, need to be understood
| Situation | Recommendation |
|---|---|
| Continuously identify vulnerabilities | Bug Bounty |
| Dynamic attack surface | Bug Bounty |
| Test human and organisational controls | Red Teaming |
| Test detection and response capabilities | Red Teaming |
| Holistic security view | Combination of both |
What regulation requires in practice
From a regulatory perspective, no single approach is sufficient.
Organisations under FINMA supervision must review their security measures regularly and continuously evolve them based on risk. In practice, this includes scenario-based testing, such as Red Teaming.
The National Cyber Security Centre also promotes structured vulnerability handling and explicitly refers to approaches such as coordinated vulnerability disclosure and Bug Bounty programs to bring in external expertise.
Frameworks such as DORA go a step further. For certain organisations, they explicitly require Threat-Led Penetration Testing (TLPT), which in practice aligns with Red Teaming. At the same time, they also emphasise the continuous, risk-based identification and remediation of vulnerabilities.
This is why a single method is rarely enough. TLPT helps validate targeted attack scenarios. Continuous approaches such as vulnerability disclosure or Bug Bounty programs help organisations maintain visibility of vulnerabilities over time and prioritise remediation.
What these requirements make clear is not that every organisation needs the same testing model, but that security testing must be continuous, risk-based, and aligned with the organisation’s context.
How the differences play out in practice
A Red Team simulates an attack via phishing, compromises a user account, and moves laterally through the network. The result: detection happens too late, and internal processes do not work as intended.
At the same time, a Bug Bounty program identifies multiple concrete vulnerabilities: an insecure API, a publicly accessible admin interface, and outdated software on a subdomain.
Both results are relevant, but they answer different questions.
Why it’s not about either/or
Red Teaming and Bug Bounty are not competing approaches. They address different layers of security:
- Red Teaming tests how well an organisation responds to attacks
- Bug Bounty reveals where attacks are possible in the first place
Relying on only one of these approaches results in an incomplete picture.
A realistic understanding of an organisation’s security posture only emerges through the combination of both perspectives.
Move beyond one-off tests. Combine continuous vulnerability discovery with real attack validation to get a complete view of your security posture.
