Every mailbox you have. And every prompt, kept as its own record.

Cloud suites, on-prem servers, object stores, decades-old PST files — and AI assistant conversations. If it holds your organisation’s communications, it drains into one sealed archive.

Rated 5 out of 5. “From 4–6 months to minutes.” — EMSL

Graph-native connectors that keep their own checkpoint, so ongoing capture never reads as a finished job.

Original MIME preserved where Graph provides it; rebuilt faithfully where it refuses.

Domain-wide delegation, audited — mail exactly as delivered, documents exported readably.

Journal unwrapping preserves BCC and distribution-list recipients; delete-after-archive drains a journal safely.

AI assistants
The channel every other archive is missing. Claude Enterprise through Anthropic's Compliance API — every prompt and every reply a sealed, supervisable record.

Connectors that refuse to fail quietly

Most archive gaps are not dramatic outages — they are quiet ones. The capture layer is built to make quiet failure impossible to miss.

Collection-window guardrails

Vendors keep exported data for days, not forever — Teams 21 days, some feeds as little as 48 hours. A schedule that cannot survive the vendor's window is refused, by name, before it costs you records.

One document, one hash

Every record's identity is the SHA-256 of its original bytes. A source-side delete removes nothing from the archive; an edit is archived as an additional version, never an overwrite.

Simulate before you connect

Every connector can run in simulation — identical paging, throttling, and checkpoints against replayed traffic — and a simulated run is physically unable to write to the archive.
