Sub7 Security (Sub7 S.à r.l) is a Luxembourg-based Web3 cybersecurity pioneer specializing in smart‑contract auditing, penetration testing, technical due diligence and security‑as‑a‑service solutions for DeFi and blockchain projects. Since launching in 2019, our team of expert auditors has reviewed 45+ smart‑contracts across Ethereum, BNB Chain and
Polygon, covering more than 812,000 lines of Solidity code and protecting over $500 million in on‑chain assets. Clients include Uniswap, Aelin, Agave, NukeVaults, Positions Finance, Blast’Em, Arbera, Beraji, SpaceHarpoon, Beracana, DigiShares, Nereus Finance, Berally, Earned Network, Blever, Twin Finance, Humanity Protocol, Uncharted, Wirex Pay, Blockinvest and more. Our security‑as‑a‑service platform, SecHub™, combines automated scanning and vulnerability discovery with advanced tools (Slither, MythX and custom bots) and manual review to deliver continuous protection and transparent reporting. Users monitor audit progress through a self‑service portal and receive actionable remediation guidance. We complement our flagship audits with GovCheck, a governance verification service that reviews on‑chain execution of DAO and DeFi protocol proposals. By March 2025, GovCheck evaluated 11 proposals across Compound, Synthetix and Kwenta, catching 1 invalid transaction and validating 10 successful proposals, thereby closing the gap between community voting and on‑chain implementation. Our growth‑hacking strategy focuses on publishing open‑source audit reports, educational blogs and interactive dashboards to attract developers and investors, leveraging SEO to drive inbound leads. In 2024 we expanded into node operations, achieving 99.60 % performance as a node operator on the SSV Network with over 600 ETH staked, 4 hosting locations, 200+ individual stakers and 14 operating networks, reinforcing our technical depth. Sub7 is a member of the Polygon Service Provider Network, Crypto Valley and the Luxembourg House of Startups, and was ranked among the top 3 startups at Cybersecurity Week Luxembourg 2022. We secured a seed funding round in 2021 to accelerate product development and international growth. With a lean team of under 10 employees, we maintain transparent processes, customized services and responsive support for clients. Choose Sub7 as your trusted partner for Web3 & DeFi security.
