IronCAP™ XMail
End-to-End, Quantum-Safe Email Security
IronCAP™ XMail is a quantum-safe, end-to-end email security system powered by IronCAP™ Crypto (ICC)—our advanced post-quantum cryptographic foundation. Built to withstand attacks from both classical and quantum adversaries, XMail delivers protection that legacy email architectures were never designed to provide.
By removing intermediary servers from the trust chain, IronCAP™ XMail helps eliminate man-in-the-middle exposure and ensures only intended recipients can decrypt your communications. This end-to-end, zero-trust design keeps every email and attachment encrypted on your device, in transit, and at rest—even if networks, servers, or accounts are compromised.
With quantum-safe digital signatures, recipients can verify authenticity instantly—confirming messages haven't been spoofed, forged, or altered. This strengthens defenses against phishing, impersonation, and business email compromise as these threats continue to rise worldwide.
If a device is lost or an account is accessed without authorization, your sensitive content remains protected. Because it is built on quantum-resistant cryptography, IronCAP™XMail safeguards communications not only for today's risk landscape, but for the long-term realities of the post-quantum era.
IronCAP™ XMail sets a new standard for email security: end-to-end, quantum-safe, and engineered for enduring trust.
How it Works
End-to-End Encryption
Unlike some secure email systems that store your emails and require your recipients to read from their servers, IronCAP™XMail provides direct end-to-end encryption with no central storage point that's vulnerable to a cyber attack.
End-to-End Digital Signature
IronCAP™ XMail lets you digitally sign your emails. Recipients can easily distinguish between your legitimate emails from those phishing ones.
Key Advantages
Quick + Easy Setup
IronCAP™ XMail will automatically detect if your email recipient has an IronCAP™ XMail account. If not, an invitation message with the link to install the software will be sent accordingly. Upon creating a free personal IronCAP™XMail account, the recipient can decrypt and read your encrypted email. It's that simple.
Zero Learning Curve
IronCAP™ XMail tightly integrates with your everyday email client such as Outlook, Gmail, Yahoo, etc. to ensure a zero learning curve. After composing your email, you can choose to encrypt and digitally sign this message with a simple click before sending it out.
Digital Document Authenticity
IronCAP™ XMail lets you sign your digital files to prove their authenticity that they are the original true copies from you rather than from a bogus hacker.
General File Encryption
IronCAP™ XMail allows you to encrypt your sensitive files such as personal finances, etc. to safeguard against cyber attacks.
