How It Works
How the Service Works
We begin by understanding your security objectives, then build a threat-focused program around them.
Scope
We agree on in-scope assets, rules of engagement and the reward table by severity.
Test
Our certified specialists probe your scope using real attacker techniques.
Validate
We reproduce and quality-check every finding before you see it.
Reward
You fix the issue and reward each validated finding by severity.
Retest
We retest your fix to confirm the vulnerability is closed.
Compare
Private Bug Bounty as a Service vs Pay Per Vulnerability (PPV)
Both models mean you pay for outcomes, not hours. They differ in how long we test and how the engagement runs. Many customers start with Pay Per Vulnerability and move to Private Bug Bounty as a Service for continuous coverage.
| Pay Per Vulnerability (PPV) | Private Bug Bounty as a Service | |
|---|---|---|
| Engagement style | Defined, time-boxed test of agreed assets | Ongoing, continuous testing of your scope |
| Who tests | Access0Day security testers | Access0Day team only, no community researchers |
| Duration | Fixed engagement window | Long-term, for as long as you choose |
| How you pay | Per validated vulnerability under PPV pricing | You reward each validated finding from a severity-based table |
| Scope | Set per engagement | Grows with your product, releases and attack surface |
| Privacy | Confidential | Closed and confidential, never shared with the community |
| Best for | Audits, launches, a quick scoped result | Security maturity and continuous assurance |

Rewards
Reward Each Finding by Severity
Rewards are agreed up front and tied to CVSS-based severity, so you know what a finding will cost before it is reported. You pay only for validated vulnerabilities.
| Severity | CVSS v3 range | Reward |
|---|---|---|
| Critical | 9.0 to 10.0 | Agreed during scoping |
| High | 7.0 to 8.9 | Agreed during scoping |
| Medium | 4.0 to 6.9 | Agreed during scoping |
| Low | 0.1 to 3.9 | Agreed during scoping |
Opt In
Set the rewards for High and Critical Findings
Choose the severities you want tested and rewarded. For High and Critical findings, Access0Day accepts the testing once the agreed reward is justified by the risk each severity represents. Medium and Low findings can follow the same reward table.
Share your scope
Tell us which applications, APIs and environments should be tested, and any areas to exclude.
Propose rewards
Set the reward you are prepared to pay for each High and Critical finding.
Reward fit review
We assess whether each reward is justified by the severity and potential impact of the finding.
Agree in writing
We confirm the reward table, scope and rules of engagement before testing starts.
Testing begins
Our specialists start testing, and you reward each validated finding as agreed.
How Access0Day Decides
Accepted
The rewards are justified for the severity, so testing starts as scoped.
Adjust and resubmit
Where a reward is too low for the risk, we recommend an adjustment before accepting the scope.
Not accepted for testing
If the rewards cannot reflect the severity, Access0Day does not take on that scope.
What the Reward Fit Review Looks At
| Severity | What the reward should reflect | Indicative examples |
|---|---|---|
| Critical | The highest business risk. The reward should sit at the top of your table and be clearly justified by the potential impact. | Remote code execution, authentication bypass, exposure of sensitive customer data |
| High | Serious risk to data or core functionality. The reward should be materially above Medium findings. | Privilege escalation, injection flaws that expose data, broken access control on sensitive records |
FAQ
Frequently Asked Questions
Who participates in my program?
Only the Access0Day security team. We do not invite community researchers or list your program publicly.
Is my information shared with anyone?
No. Reports and findings remain private between you and Access0Day and are never shared with a researcher community.
How is this different from PPV?
PPV is a defined, time-boxed engagement. Private Bug Bounty as a Service is continuous, with a scope that evolves alongside your product and a reward for each individual validated finding.
What if my proposed rewards are too low for the severity?
We recommend an adjustment during the reward fit review. Testing for that scope starts once the rewards are justified for the severity.
How do I reward findings?
You reward each validated finding according to the severity-based reward table agreed during scoping.
Do I pay for duplicate or invalid reports?
No. We validate every finding first, so you only see and reward verified vulnerabilities.
Can we start with PPV and move to the private service later?
Yes. This is a common path, and what we learn during your PPV engagement carries into the private bug bounty service.
