About Crowdfense

We acquire high-impact vulnerabilities that pose significant security risks and are accompanied by a fully functional, reliable exploit (preferably with a PoC or weaponised chain).

Eligible submissions typically target:

  • Modern desktop and mobile operating systems

  • Widely deployed enterprise software

  • Embedded, IoT, and network devices

For detailed scope, platform coverage, and specific requirements, please refer to our Exploit Acquisition Program.

While vendors may offer limited rewards and impose disclosure constraints, Crowdfense provides a more rewarding, efficient, and researcher-centric alternative.

Key benefits:

  • Significantly higher payouts: We offer the highest bounties in the industry, far exceeding typical vendor rewards.

  • No public disclosure pressure: Unlike vendors, we don’t require you to follow coordinated disclosure timelines or share your work publicly.

  • Full confidentiality: Your identity and submission are handled with strict discretion.

  • Streamlined process: Our Vulnerability Research Hub (VRH) makes it easy to securely submit, track, and get paid for your research.

By reporting to Crowdfense, you maintain control, confidentiality, and maximum reward for your work.

At Crowdfense, we offer the highest payouts in the industry for high-impact vulnerabilities. We believe top-tier researchers deserve top-tier rewards, and we back that belief with real, competitive compensation.

Our Vulnerability Research Hub (VRH) provides a secure, streamlined, and transparent submission process, guiding you from the initial report to final payout with complete confidentiality and expert support.

Whether you're submitting a single exploit or building a long-term relationship, Crowdfense ensures that your work is valued, protected, and rewarded.

We often seek vulnerability researchers to join our internal zero-day research team. Crowdfense researchers conduct cutting-edge vulnerability research and exploit development. They find zero-day vulnerabilities, write in-depth root-cause analyses, contextualise the vulnerabilities and attack vectors, and identify patterns in emerging and established attack surface areas. Visit our careers page to find employment opportunities.

Crowdfense collaborates with government institutions, including national security, intelligence, and law enforcement agencies (LEAs), as well as trusted system integrators that require access to advanced zero-day exploits and cybersecurity capabilities.

We maintain rigorous export control, compliance, and due diligence protocols, applying the highest vetting standards in the industry. This ensures that every partnership is conducted with complete transparency, accountability, and legal oversight.

Crowdfense does not use the acquired vulnerabilities directly. Instead, we act as a trusted intermediary: after thorough technical validation and documentation, each approved submission is delivered to the client who contracted us to procure such capabilities.

We ensure that:

  • The research meets strict quality, reliability, and impact standards

  • It is tailored to the client's requirements and operational context

  • All transfers are conducted under strict legal, compliance, and export control frameworks

Our role is to bridge top-tier offensive research with vetted partners, ensuring responsible use of advanced cyber capabilities.

Unlike public bug bounty platforms, Crowdfense offers private, high-stakes acquisitions focused exclusively on zero-day and high-impact vulnerabilities.

Key differences:

  • Unmatched payouts: We pay the highest bounties in the industry, often significantly exceeding what traditional platforms offer.

  • Private and exclusive: We operate a confidential, invite-only environment, ensuring that your research is handled securely and discreetly.

  • No vendor disclosure: We do not require coordination with affected vendors or public disclosure timelines.

  • Streamlined process: Our Vulnerability Research Hub (VRH) provides a smooth, secure experience from submission to payment.
