Encryption for independent auditors — engagements sealed per client
Independent auditors handle other people's numbers under strict confidentiality. Elba lets you keep each engagement in its own sealed vault — no firm-wide SaaS, no vendor between you and the client's file.
A vault per engagement
Working papers, evidence PDFs, and management-letter drafts all in one place. When the engagement closes, archive the sealed vault to long-term storage.
Retention discipline
Encryption doesn't change your retention rules. Elba only makes sure the archive stays unreadable to anyone without the password for the years it must be kept.
Questions people actually ask
- Is a sealed vault acceptable to my professional body?
- Most professional bodies require AES-256 at rest for client files. Elba meets that bar.
- Can I share a vault with a client for review?
- Yes — hand over the sealed folder and the password out of band.
Take the island
Elba is one HTML file. It runs locally in a Chromium browser, seals a folder with AES-256-GCM, never phones home, and becomes open source on 1 January 2030.
