Both vendors encrypt email centrally in the mail flow, with the same standards. The difference is who runs the gateway and what else comes from the same platform. This page puts both side by side and backs every statement about CipherMail with a public source.
In short
Conbool is an email security suite from Germany with nine modules, as a managed cloud service or on-premises, with Conbool GmbH in Hamburg as the contracting party. CipherMail B.V. states that it is based in Amsterdam, was founded in 2008 and is privately owned, and offers an encryption gateway, a webmail messenger, an Android app and an Outlook add-in, under either a community open-source or a commercial licence. Both support S/MIME, PGP, TLS and PDF encryption.
Side by side, with a source for every statement about the competitor.
Conbool runs the service, including updates, monitoring and certificate management. On request the same suite runs in your own data centre, still with support.
CipherMail offers the gateway under either a community open-source or a commercial licence; the source code is, by its own account, hosted on GitLab.

S/MIME and PGP at the gateway, TLS, encrypted PDF and a message portal for recipients without a certificate. Which method applies is not decided by the recipient alone: a rule can also be tied to attachment, file type and message size. S/MIME without an attachment and a password-protected PDF with one is a matter of two rules.
CipherMail names S/MIME, PGP, TLS and PDF encryption, plus the webmail messenger as a path to recipients.

Hosting in Germany, the contracting party is Conbool GmbH in Hamburg.
CipherMail B.V. gives Amsterdam as its seat, founded in 2008, privately owned. The website makes no statement about hosting; with a self-run gateway the operator decides.

Nine modules on one platform: spam and phishing protection, encryption, file transfer, archiving, signatures, DMARC reporting, 365 Backup, awareness and continuity.
Besides the gateway the website lists the webmail messenger, an Android app, an Outlook add-in, integrations for Microsoft 365 and Google Workspace, and archiving and eDiscovery.

Updates, monitoring, certificate management and availability sit with the vendor, in both operating modes.
Under the community licence, installation, updates and monitoring sit with the operator; the website names the commercial licence as the alternative.

Migration
The path is the same as for any change in the mail flow and needs no cut-off date with downtime.
Which domains, which mailboxes, which groups of recipients are affected? That produces the rule list.
Conbool is added as a second path while the existing service keeps running. Two test mailboxes are enough for the first pass.
Rules, exceptions and recipient lists are carried over and checked one by one.
The mail flow is switched over; message tracing shows every delivery. The previous service stays reachable until the observation period ends.
The old path is cancelled only once nothing runs through it any more.
Messages already encrypted and existing keys remain usable. Please clarify the export of keys and configuration before an existing gateway is shut down.
