IRONKEEP vs PreVeil
PreVeil adds an encrypted layer on top of your existing email. That sounds simple. In practice, you are now managing two email systems, neither of which is complete on its own.
| PreVeil | IRONKEEP | |
|---|---|---|
| Architecture | Overlay on existing email | Complete platform |
| Calendar and contacts | Not included | ✓ |
| External recipients | Need PreVeil account | Standard email |
| Underlying system compliant | No | Yes |
| Systems to manage | Two | One |
It is an overlay, not a platform
PreVeil is not a replacement for your email provider. It sits on top of Gmail, Outlook, or Exchange as an encrypted enclave. Your organization still needs a separate email system underneath. That means two systems to manage, two sets of credentials, and two places where email lives.
CUI goes through PreVeil. Everything else goes through your regular email. Your team has to decide, for every message, which system to use. That decision is where compliance breaks down.
External recipients need PreVeil too
When you send a PreVeil-encrypted email to someone outside your organization, they receive an invitation to create a free PreVeil account. Recipients can use PreVeil Express in a browser without installing software, but they still need to create an account and authenticate through PreVeil's system. For organizations that communicate with dozens of subcontractors, vendors, and government contacts, this creates friction in every exchange.
PreVeil offers an Email Gateway for external parties, but it requires a separate license and hosting agreement. The gateway handles address translation and routing, adding another moving part to an already fragmented system.
No calendar, no contacts
PreVeil provides encrypted email and encrypted file sharing. It does not include a calendar. It does not include contacts management. For those, you still depend on your underlying email platform, which, if it is standard Gmail or Outlook, is not compliant for CUI. You end up with a compliant inbox but a non-compliant calendar.
The underlying email is still non-compliant
PreVeil has achieved DoD FedRAMP Moderate equivalency for its encrypted enclave. But PreVeil's enclave model assumes you can cleanly separate CUI from non-CUI communications. In practice, this is difficult. Metadata, subject lines, and reply chains often cross the boundary.
The equivalency applies to PreVeil's encrypted layer, not to the Gmail or commercial Outlook underneath. Your base email system still does not meet FedRAMP Moderate requirements on its own. You are relying on a clean separation between two systems that share the same inbox.
Reliability concerns
User reviews report issues with file corruption, email synchronization problems, and accounts disappearing from the admin console without explanation. For a system handling CUI, reliability is not optional. It is a compliance requirement.
How IRONKEEP is different
IRONKEEP is not an overlay. It is a complete platform. Email, calendar, contacts, and file storage in a single compliant environment. No second system. No split inbox. No asking your subcontractors to install software. Migrate your email, files, and contacts and get compliant in hours.
- Complete email platform with calendar and contacts
- Standard email protocols: recipients do not need special software
- FedRAMP Moderate (or higher) authorized infrastructure: no non-compliant system underneath
- Designed for CMMC Level 2, NIST 800-171, DFARS, and ITAR
Every email your team sends through a non-compliant system is a compliance risk you're choosing to keep.
