What is Dual Defense? How Double-Layered Audits Improve Cybersecurity

What is DualDefense?

DualDefense is a next-generation security service designed to provide the highest level of protection for digital projects. Unlike traditional audits that rely on a single team of professional auditors, DualDefense combines multiple layers of review to maximize coverage and uncover potential vulnerabilities before they can affect users.

At its core, DualDefense pairs a professional audit with a crowdsourced security review. After a verified auditor completes a thorough evaluation of a project’s code or infrastructure, a diverse team of ethical hackers performs an additional review. This ensures that the audit captures both methodical, structured insights and creative, real-world perspectives.

By combining these approaches, DualDefense helps projects reduce risk, enhance trust with users and investors, and strengthen overall security.

This approach works for a variety of digital systems — from Web3 projects to traditional Web2 applications — offering them comprehensive protection backed by a community of skilled security professionals and ethical hackers.

Two Layers of Protection

At its core, DualDefense pairs a professional audit with a crowdsourced security review. After a verified auditor completes a thorough evaluation of a project’s code or infrastructure, a diverse team of ethical hackers performs an additional review. This ensures that the audit captures both methodical, structured insights and creative, real-world perspectives.

Why Multi-Layered Reviews Matter

Even after comprehensive audits, additional reviews by independent researchers often uncover issues that might otherwise remain hidden. In fact, our DualDefense experience shows that independent researchers frequently discover vulnerabilities that were not identified in the initial audit. This proves the importance of multi-layered reviews.

The Outcome

By combining these approaches, Dual Defense helps projects reduce risk, enhance trust with users and investors, and strengthen overall security. This approach works for a variety of digital systems — from Web3 projects to traditional Web2 applications — offering them comprehensive protection backed by a community of skilled security professionals and ethical hackers.

Why a Single Audit Isn’t Enough

Traditional audits are valuable, but they have inherent limitations. Each auditing team or solo auditor usually follows an established workflow and consistent approach. Over time, this can cause a kind of “tunnel vision,” where the same patterns of review are applied repeatedly, potentially missing unexpected vulnerabilities.

DualDefense addresses this limitation by introducing an additional, crowdsourced layer. Independent ethical hackers with diverse experience and fresh perspectives examine the system, often identifying issues that a single team might overlook. This multi-layered review provides a more comprehensive check, reduces blind spots, and ultimately delivers a higher level of confidence in your project’s security.

In short, combining structured professional audits with dynamic crowdsourced testing creates a holistic security assessment that is always stronger than relying on a single source.

Key Benefits of Dual Defense

• Comprehensive coverage: Combines methodical review of traditional audits with diverse testing from crowdsourced security experts.
• Cost efficiency: One engagement delivers the value of both traditional and crowdsourced audits.
• Faster detection: Crowdsourced findings complement structured insights from expert auditors.
• Consolidated reporting: All results are presented in a single, actionable report.
• Confidence in security: Demonstrates to stakeholders and users that the project has undergone rigorous, multi-layered protection.

How DualDefense Works

The DualDefense process is structured in nine clear steps, ensuring both professional and community-driven protection:

1. Company requests DualDefense service

A company reaches out to request the DualDefense audit. At this stage, the chosen security provider gives an approximate estimate of the time, complexity, and cost of the audit.

2. Security provider conducts internal audit

A professional security auditor (for example, a blockchain security auditing firm) reviews the project’s code and delivers an initial report with findings and recommendations.

3. Creating Flash Pool for bug hunters and $HAI investors

Up to 20% of every audit fee is allocated to build a short-term (1-month) Flash Pool. This pool funds rewards for bug hunters during the crowdsourced phase and offers attractive yields (up to 180% APY) for $HAI investors who stake their tokens to support security.

4. Launch marketing campaigns

Marketing efforts of HackenProof team are initiated to attract skilled ethical hackers and inform the wider security community about the new crowdsourced audit.

5. DualDefense audit verification and approval

The audit is verified and approved for public listing, ensuring all requirements are met before opening it to the hacker community.

6. Crowdsourced audit launch

Once the Flash Pool is ready, the project sets up its program on HackenProof: creating a profile, defining the rules, and launching a 1-month crowdsourced audit contest. Ethical hackers from around the world join to review the code from fresh perspectives.

7. Triage of vulnerability reports

Incoming bug reports are carefully reviewed by security experts. Valid vulnerabilities are confirmed and categorized, with critical threats highlighted for immediate fixing.

8. Reward distributions from the Flash Pool

• If critical bugs are discovered and verified, bug hunters receive rewards directly from the Flash Pool.
• If no critical issues are found, $HAI investors benefit by receiving distributions from the Flash Pool — earning yields of up to 180% APY.

9. Delivery of the final consolidated report

At the end of the process, the company receives a comprehensive final report consolidating all findings. The most important issues are highlighted, making it simple for the team to understand the security posture of their product and take the necessary next steps.

Experiences of Companies Using DualDefense

Many companies have successfully leveraged DualDefense to strengthen their security posture. Projects such as Cueva, Strobe, Majority Games, CoinDepo and many others have gone through the process.

DualDefense creates a win-win scenario for any project:

• If critical bugs are found, the team can fix them, improving the product’s safety.
• If no critical bugs are detected, the audit confirms the product’s robustness, providing assurance to stakeholders and users.

In both scenarios, the project benefits by gaining confidence in its security. This makes DualDefense a valuable tool for teams who want to minimize risks and demonstrate their commitment to safety.
