Blob CRM

Security

Last updated: 21 July 2026

1. Tenant isolation

Every workspace lives in its own SQLite database file on disk. Two tenants cannot read each other's data, because the rows are in physically separate files — not just logically separated by a tenant column. The same isolation extends to uploaded files (per-tenant directory tree) and to authentication (each tenant has its own user table).

2. Authentication

3. Transport & perimeter

4. Encryption at rest

Tenant databases live on EBS volumes that are encrypted with AWS-managed KMS keys (AES-256). Daily encrypted snapshots are retained for 90 days. Uploaded attachments are stored under the same encrypted volume.

5. Backups

Every tenant database is snapshotted to disk on a rolling daily schedule. Snapshots are kept for 90 days by default (configurable per tenant in Settings → Backups). Restores are point-in-time to any snapshot in the window.

6. Audit log

Every create, update and delete to your CRM data is recorded in a per-tenant audit log with the actor, action, entity, ID, before/after diff, and timestamp. The auth log records every login + logout with IP + user agent. Both are viewable from the in-app Settings → Audit log and Settings → Users → Auth log.

7. Outbound webhooks

Every outbound webhook payload is signed with HMAC-SHA256 over the JSON body, using a per- subscription secret. Subscribers verify the X-Blob-Signature header to confirm the payload was issued by Blob and not tampered with.

8. Vendor sub-processors

We use a small set of sub-processors. The current list is in our DPA Schedule 1; we'll email workspace admins before adding a new one.

9. Responsible disclosure

If you find a security issue, email [email protected]. We respond within one business day. Please don't publish details before we've had a chance to fix.
