Illustrative dashboard preview — sample data, not a live workspace.

One quiet source of truth

Spend less. Review less. Prove more.

Fallow is intentionally narrow: identify inactive access, run better user access reviews and create evidence an auditor can trust.

01

Find inactive seats with financial context

Turn activity signals and public SKU pricing into a ranked list of reclaimable monthly spend.

02

Review access without spreadsheet fatigue

Assign reviewers, focus on material changes, record decisions and keep every hand-off moving.

03

Hand auditors complete, immutable evidence

Target architecture: JSON evidence includes reviewer identity, timestamps, decisions and an artifact SHA-256 digest. The JSON evidence workflow ships in the preview; PDF generation is unavailable in the current release.

Meet your stack

Microsoft first, by design.

Fallow ships a verified Microsoft CSV analysis path. Additional provider connections are planned and are not connectable in the current release. See the current integration status.

Private by architecture

Your tenant data is not support material.

01

Per-tenant encryption

Every workspace has its own Azure Key Vault key. One tenant’s key cannot decrypt another tenant’s data.

02

Raw data stays out of Postgres

Raw scan responses are encrypted immediately in regional blob storage and automatically expire.

Read the security model →
03

No operator access

Fallow support tooling exposes workspace metadata only. There is no customer impersonation mode.

Read the security model →
04

Short-lived report access

Reports leave encrypted storage through signed, single-file links that expire after 15 minutes.
