In three sentences

What matters.

Reddoxx and Conbool are both German vendors with a GoBD focus and a small product family. Reddoxx comes from the appliance world and covers archiving, spam protection and encryption. Conbool is cloud-native and delivers the identical product on-premises too, with a broader suite (MailGuard, SecureMail, SecureFiles, Disclaimer, DMARC) and cleartext search over S/MIME and PGP mail decrypted in the gateway.

The five most common questions in a direct comparison.

Statements about Reddoxx reference public sources; every Conbool claim is verifiable in a demo.

Cloud-native or appliance?

Conbool Archive

Conbool is built as an EU cloud and delivers the same codebase fully on-premises too. There is no appliance to maintain; updates run centrally. The data location is named in the DPA, the contracting party is Conbool GmbH.

ReddoxxReddoxx MailDepot

Reddoxx comes from the appliance world and is operated on-premises as a virtual or physical appliance, with cloud options in addition. Reddoxx is a German vendor.

Source: Reddoxx product pages (MailDepot, appliance/operating models), publicly available.

Why this matters: An appliance gives full control but ties operations, updates and scaling to you. A cloud-native product with optional on-premises gives you the choice without two separate architectures.

How broad is the suite?

Conbool Archive

Archive is part of a suite of five modules: MailGuard (inbound protection), SecureMail (encryption), SecureFiles (large file transfer), Disclaimer and DMARC. One portal, one audit log, one licensing logic.

ReddoxxReddoxx MailDepot

Reddoxx also offers a product family: MailDepot (archiving), Spamfinder (spam protection) and MailSealer (encryption). The focus is on these three disciplines.

Source: Reddoxx product overview (MailDepot, Spamfinder, MailSealer), public.

Why this matters: Both bring a suite. Conbool additionally covers signatures and DMARC reporting in the same stack; if you want to consolidate those, Conbool has fewer separate building blocks.

Are encrypted messages searchable?

Conbool Archive

S/MIME and PGP messages that the Conbool gateway decrypts (SecureMail is part of the suite) are additionally archived in searchable cleartext. The encrypted original stays unchanged in the mailbox.

ReddoxxReddoxx MailDepot

Reddoxx archives messages as they are captured. Whether encrypted content is available in cleartext depends on whether it was decrypted before archiving.

Source: Reddoxx MailDepot archiving documentation, public.

Why this matters: For practical eDiscovery over S/MIME or PGP traffic, searchability is decisive. The benefit applies to mail the gateway decrypts.

How do messages get into the archive?

Conbool Archive

The native gateway tap captures every message in the mail flow, and journaling receives Exchange/M365 journal reports at a dedicated ingestion address (multiple sources per tenant). Journaling also captures internal mail. Legacy data via PST, MBOX and EML import.

ReddoxxReddoxx MailDepot

Reddoxx captures via SMTP integration or journaling and imports legacy data. As an appliance, Reddoxx typically sits in the mail flow or receives journal copies.

Source: Reddoxx MailDepot product page, capture methods, public.

Why this matters: Both capture in the mail flow and via journaling. Conbool's journaling allows multiple separate sources with their own sender allowlist and captures internal mailbox-to-mailbox mail.

What about GoBD and evidence?

Conbool Archive

WORM with object lock in the compliance tier, an externally anchored hash chain, an automated deletion concept under German commercial and tax law, eDiscovery with dual control and SIEM export of the audit log. An IDW PS 880 audit is in preparation.

ReddoxxReddoxx MailDepot

Reddoxx advertises audit-proof, GoBD- and GDPR-compliant archiving and is established in the German market.

Source: Reddoxx website (GoBD/GDPR/audit-proof), public.

Why this matters: Both address GoBD and audit-proof archiving. Conbool adds an externally anchored hash chain and SIEM export to the evidence; the formal IDW PS 880 audit is in preparation at Conbool.

Migration checklist

What a switch from Reddoxx concretely involves.

A Reddoxx switch runs as a parallel migration in five steps. The archive is exported and adopted before the Reddoxx appliance is shut down.

  1. 1. Review Reddoxx scope and operation

    Capture mailbox count, archive size, the operating model (appliance/cloud) and the capture methods in use. This determines import effort and the cutover point.

  2. 2. Export the Reddoxx archive

    Export the existing archive from MailDepot as EML or PST. This export is the basis for the legacy import into Conbool so the history is preserved.

  3. 3. Point capture at Conbool

    Create a journal source in Conbool Archive and point the journal rule or mail flow at Conbool. From this point new mail flows into Conbool while Reddoxx keeps running during the transition.

  4. 4. Import legacy data and verify in parallel

    Ingest the EML/PST export server-side into Conbool. Periods are calculated from the send date. Verify search, completeness and periods on a sample.

  5. 5. Decommission the Reddoxx appliance

    Once new mail runs through Conbool and legacy data is verified, the Reddoxx appliance is decommissioned in a controlled way. Respect retention obligations during the transition.

These steps are an experience grid and do not replace individual migration advice. We adapt scope and order to your setup in a consultation.

Decision aid

When Conbool Archive, when Reddoxx.

Conbool Archive fits when …

  • you want to start cloud-native and optionally run the same solution on-premises, without appliance maintenance.
  • you want to consolidate inbound protection, signatures and DMARC reporting alongside archiving in the same stack.
  • heavy S/MIME or PGP traffic should be searchable in cleartext (for gateway-decrypted mail).
  • you want to capture internal mail completely via journaling and need modern eDiscovery with dual control and SIEM export.

Reddoxx fits when …

  • you deliberately prefer an on-premises appliance with full self-control.
  • a long-established German archive appliance is an award criterion for you.
  • you cover exactly the three disciplines archiving, spam protection and encryption from Reddoxx and need no more.
  • existing Reddoxx appliances already run in your environment.
