TrustLayer Mail: Compliant Email Archive Reviews & Product Details

TrustLayer Compliant Email Archive gives organisations a centralised, tamper-proof email repository for compliance, eDiscovery and everyday email recovery. Every message sent, received or exchanged internally is captured and stored in a separate, secure cloud archive, so you can answer a regulatory disclosure, an internal investigation, a GDPR Subject Access Request or a lost email in seconds rather than days. How it works Capture is journal-based. Your email platform sends a copy of every message to the archive using its standard journalling feature, so there is no proxy in the traffic path and no MX change. Exchange (all versions), Exchange Online in Microsoft 365, Google Workspace, Domino and GroupWise are supported, with EWS and IMAP collection available as alternatives to SMTP journalling. Setup takes minutes and needs very little day-to-day administration. Archived messages are de-duplicated, compressed, indexed and encrypted with AES-256 at rest and TLS in transit, then held in a high-availability cloud hosted on AWS. You choose your data location at provisioning: London (UK) or Frankfurt (EU). Retention is configurable, from indefinite to automatic deletion at a set age, and retention changes are gated behind Data Guardian approval. Search covers sender, recipient, subject, body, dates, keywords, wildcards and attachment content. Users can open results in their native email client, forward, restore to their mailbox, print or save to PDF, and an Outlook add-in lets them browse their personal archive without leaving Outlook. Governance built in Five access levels keep control tight. Standard users see only their own nominated addresses. Privileged users run eDiscovery searches across some or all mailboxes, with a full audit trail of what was searched and opened. Data Guardians, typically a DPO or Compliance Officer, review privileged activity and receive alerts whenever a search runs. Privileged and Delete users can remove messages through an audited process to support the right to be forgotten. Administrators manage accounts and settings but cannot search the archive. An immutable audit log of all search activity, AD and SSO authentication with Multi-Factor Authentication, and audit reports emailed automatically to designated mailboxes give you the evidence of governance that auditors ask for.
