How Does DualDefense Work?

A structured five-step process that layers community-driven review on top of your existing audit.

Request a DualDefense Audit Quote

The company receives an approximate estimate of the timeline, complexity, and cost based on our risk-based methodology.

Run DualDefense Audit

HackenProof sets up the company profile, defines the rules, and launches a crowdsourced audit focused on critical vulnerabilities — running on the HackenProof platform for up to one month.

Focus on Confirmed Criticals

HackenProof security experts review and validate incoming reports from bug hunters, so the company can concentrate only on confirmed critical threats.

Fix Valid Issues

The company's team fixes the confirmed critical vulnerabilities, followed by a remediation check from HackenProof and security researchers.

Get Final Branded Report

HackenProof delivers a final report confirming all validated criticals are resolved (or that none were found) — ready to share with investors, shareholders, or the community.

What Are the Features of HackenProof’s DualDefense?

Pay Less, Cover What Matters

You pay a fixed price for your DualDefense program — typically 10–20% of your initial audit cost, with no per-finding charges. It covers all confirmed critical vulnerabilities found, keeping costs predictable.

How DualDefense Differs from a Crowdsourced Audit

DualDefense adds a targeted post-audit security layer focused on confirmed critical vulnerabilities, while a crowdsourced audit provides broader community review from the start.

Main goal	Broad vulnerability coverage	Find missed critical vulnerabilities
Severity focus	Low, Medium, High, Critical	Critical only
Payment model	Custom quote. Fixed price or pay per severity category	Fixed price. 10–20% of the initial audit cost
Best for	General security review	Post-audit validation

DualDefense was the perfect fit for our project. The two-layer approach delivered more value than any audit process we've used so far. The HackenProof team stayed on top of every issue, letting us focus on what matters. We're definitely looking forward to working together again.

Jhelison Gabriel Lima UchoaCTO

We ran a DualDefense audit with the HackenProof team to add an extra security layer on top of our initial audit. The whole process was smooth and seamlessly organized. What we valued most is how the DualDefense team filtered and deeply reviewed the findings before handing them over, the experience of the review team really showed in that prework, and it made our job significantly easier. We got exactly the results we expected, and we'd happily recommend DualDefense to other projects. We're definitely looking forward to working together again.
