Nillion

Nillion builds decentralized infrastructure for what it calls “blind computation” — processing sensitive data (credentials, financial records, biometric or health data) without ever decrypting it on any single node, using a technique called Nil Message Compute (NMC) so no individual party in the network can see the underlying data. The pitch is to let applications compute on encrypted data directly rather than relying on traditional encryption-at-rest-and-in-transit models that still expose plaintext during processing.

Founded in 2022 and headquartered in Zug, Switzerland, Nillion has raised roughly $50M, including a $25M round led by Hack VC in October 2024, and launched a native token (NIL) in 2025 as part of a broader decentralized-network model rather than operating as a traditional enterprise SaaS vendor. Its backers and ecosystem partners include several blockchain infrastructure projects (Arbitrum, NEAR, Aptos), reflecting its roots in the crypto/Web3 privacy-tech space more than the traditional enterprise security market.

Nillion’s privacy-preserving computation approach is technically credible as an extension of the broader secure multi-party computation (MPC) research field, but it is architecturally and commercially closer to Web3 infrastructure than to a conventional enterprise data-protection product; this site includes it because privacy-preserving computation on sensitive data is a legitimate data-protection capability, but CISOs evaluating it should recognize it targets decentralized-application builders rather than typical enterprise IT buyers today.
