Salus Security

What Salus Security does

Salus Security is a Web3 security firm founded in 2022 that delivers three core services: smart contract auditing, Web3 penetration testing, and zero-knowledge (ZK) solutions. The company serves blockchain protocols, decentralized applications, DeFi platforms, and Bitcoin ecosystem projects across more than 15 blockchain networks, including EVM chains (Ethereum, Arbitrum, BNB, Polygon, Optimism, AVAX), Bitcoin, TON, Solana, NEAR, Aptos, Sui, EOS, Polkadot, and Starknet. Marquee relationships include Binance Labs, MarketAcross, and GoPlus Security, alongside a long-tail portfolio of 300+ audited projects with a self-reported zero-exploit record.

The company's technical stack is organized around three differentiated capabilities. The smart contract audit service uses a Proof of Concept (PoC) methodology with line-by-line review and threat modeling to maximize vulnerability discovery. The penetration testing service applies a red-team approach covering network, cloud, web application, and mobile application layers combined with blockchain-specific middleware and anti-tampering testing. The ZK solutions offering provides end-to-end services from business consultation through circuit design, development, integration, and deployment, with claimed unique capability to deploy ZK upgrades on existing Solidity-supported applications without requiring chain migration. Internal expertise spans proof systems (Groth16, Plonk, UltraPlonk, Halo2, zkStark) and commitment schemes (KZG, IPA). Salus has published research in collaboration with Sequoia, the Ethereum Foundation's PSE team, and 0xPARC on ZK and AI intersections, including Linea Dark Pool research published on Ethereum Research.

The business is a professional services firm operating on project-based pricing. ZK engagement budgets are publicly tiered at $30K-$50K, $50K-$100K, and $100K+, while smart contract audit and penetration testing pricing is custom per engagement. Go-to-market combines direct sales (website form at salusec.io and email at [email protected]), community-led growth via the Salus Sentinels partner network (40+ ecosystem partners), event-driven demand generation at Web3 conferences, and partner co-marketing with Binance, Linea, Arbitrum, and others. The legal entity is Salus Holding LTD, incorporated in the Cayman Islands (72 Market Street, Camana Bay), with operational presence in Singapore and a fully remote, globally distributed workforce. The company is privately held and backed by Binance Labs and Sequoia, with no public revenue disclosures.
