Application-Level Data Protection Through Serverless Distributed Key Cryptography

Absio is a Denver, Colorado data security company that sells encryption and key management as developer infrastructure rather than as a perimeter product. Its stated origin is military intelligence work, where the founding team was tasked with protecting highly mobile information sharing in contested battlefield conditions. The resulting technology is aimed at software developers and product teams who need to build data protection directly into applications, reduce downstream customer risk, and satisfy privacy regulations across jurisdictions.

The approach centers on what the company calls Serverless Encryption, built on a patented method of software-defined distributed key cryptography. All keys are generated on the device, server or browser running the application rather than by a remote key server, with private keys held in an encrypted key file protected by a password-derived key. SDKs expose user registration and authentication, encrypted containers with granular access grant and revoke, key exchange between users, digital signing and HMAC verification, and hashing for pseudonymization.

What distinguishes the model is the removal of a central key repository and any dependency on a third-party key service, so protection travels with the data across desktop, mobile, IoT, browser, cloud and server environments. SDKs ship for C#, JavaScript, Python, Java and Swift with cross-language compatibility and FIPS-compliant algorithms, supporting secure messaging, file sharing and digital rights use cases. Alongside the toolkit the company offers assessments, custom development and security architecture consulting.
