Immunefi is the leading crowdsourced security platform for Web3
About
Immunefi, the leading crowdsourced security platform for web3, was founded in 2020 with a clear mission: to make web3 safe for onboarding the world.
With billions lost to hacks each year, we believe that security is the great blocker to web3 adoption. That's why we're here.
Our results speak for themselves:
- $25B+ in onchain hack damage averted
- 60,000+ whitehats
- $116M+ paid in rewards to security researchers
- $180B+ in assets under protection
- 500+ protocols secured
Since its founding by CEO Mitchell Amador, Immunefi now has over 50+ employees around the world. If you're interested in joining the team, please see our careers page.
History
We began with Bug Bounty Programs, enabling security researchers to responsibly disclose onchain vulnerabilities before they could be exploited. This approach proved critical, and Immunefi became the market leader for onchain BBPs, preventing billions in hacks, and paying out some of the largest bounties in the history of web3.
As the onchain economy continued to evolve, so did the threat landscape. To better secure the entire web3 software development lifecycle, we expanded our suite of onchain security solutions.
Since 2024, we’ve launched new, industry-defining innovations beyond bug bounties, including:
- Audit Competitions – Time-bound code reviews from best-in-class security researchers.
- Attackathons – Large-scale, education-based competitions where security researchers form a long-term security community around your ecosystem and compete over a reward pool.
- Invite-Only Programs - Time-bound code reviews from a curated group of security researchers best-suited to hunting on your program.
- Audits: Security audits from a matchmade group of the most elite and proven web3 security researchers.
- PR Reviews: Bringing proactive, continuous security reviews into the heart of your dev process.
The learnings and successes from 500+ crowdsourced security programs have led to our most powerful innovation to date: Immunefi Magnus.
Immunefi Magnus: The Next Chapter for Onchain Security
In 2025, we announced Immunefi Magnus — a unified SecOps command center for the onchain economy.
Magnus solves the biggest challenges in onchain security: Fragmented tools, siloed workflows, and manual processes that increase risk and slow down response.
Magnus operates across four pillars:
- Aggregate: Unifying the full onchain security stack into a single platform. Tools are sourced from leading security providers in every category and integrated together.
- Orchestrate: Security Swarm, Immunefi's automations engine, powers SecOps automations that autonomously detect and mitigate threats. All while minimizing overhead and watching over your infra 24/7.
- Agentify: Our role-specific security agents optimize key security defenses across your protocol's security stack.
- Evolve: Through Codexa, Immunefi’s proprietary dataset of onchain vulnerabilities, Magnus provides a security system that improves with you, continuously adapting to future threats.
With Magnus, Immunefi is opening a new chapter for onchain security — unified, intelligent, and always-on.
One Platform. Unified Security Operations. Complete Onchain Protection.
