Security
A fortress around every message.
Security shapes how BlackVault Mail is built, from how mail is stored to how it is sent.
Encrypted at rest
Your messages and attachments are encrypted before they are stored.
Authenticated sending
Outgoing mail is signed and aligned with SPF, DKIM and DMARC for every domain. That helps it reach inboxes and helps protect your domains from spoofing.
Per-tenant isolation
Each organization’s data is kept separate from every other’s and protected with encryption keys of its own.
Your own domains
Bring your domains and your brand. You keep control of your DNS, and mail is always sent as the domain it belongs to.
No data mining
We don’t scan your mail for advertising, build profiles, or sell your data.
How it works
From your domain to your fortress in four steps.
