Protecting Data-in-Use is the Next Frontier in Cloud Security
Mimir pioneered the first data-in-use security solution for SaaS platforms - ensuring that data is protected, even when accessed.
How BrunnerDB Works
Even with Zero Trust, data must be decrypted to process – creating an unpatchable attack surface. Monitoring tools detect threats but don’t eliminate threat exposure.
Data Chunking & Local Encryption
BrunnerDB encrypts data at the user’s device before upload. This eliminates the needfor server-side key management and reduces backend CPU overhead.
Embedded Security Layer
BrunnrDB integrates directly into your application stack as a transparent SDK or drop-in service — no disruption to your existing user experience.
Distributed Processing at the Edge
Instead of central compute loads, BrunnrDB shifts processing to secure browser-based sandboxes. This significantly reduces cloud compute costs while preserving performance.
Zero-Exposure Architecture by Design
BrunnerDB eliminates the traditional attack surface by ensuring data remains encrypted across all states and throughout the entire stack:
At Rest
Encrypted blobs stored on the server – server holds no keys
In Transit
Encrypted packages transmitted over TLS and internal protocols
In Use
All decryption and processing occurs locally within ephemeral WebAssembly-based sandboxes.
No Root Access
Even system-level compromised cannot expose user data.
Built By Developers, For Developers
BrunnerDB was designed from the ground up with engineering teams in mind.
API-First SDK
TypeScript and Rust wrappers make it easy to embed BrunnrDB into modern SaaS stacks.
Zero PlugIn Overhead
Works in any modern browser – no extensions, agents, or install friction.
Stateless by Design
Fully supports disconnected mode with audit-ready state management.
Fast Integration
Deploy in hours, not weeks – no backend re-architecture required.
