Secure every email. Trust every message.
PKI-powered email security that cryptographically authenticates every sender, guarantees message integrity, and ensures only the intended recipient can read what you send, automatically.
From Certificate Authority to verified inbox
Four interlocking layers create an unbroken chain of cryptographic trust for every email you send.
Certificate Authority
A dedicated CA for your domain, the trusted anchor that issues and manages all user certificates.
User certificate issued
Each user gets a unique X.509 certificate binding their address to a private key only they hold.
Sign & encrypt
Outgoing mail is automatically signed with the sender's key and optionally encrypted with the recipient's, transparently.
Verify & decrypt
The recipient's client validates the chain, confirms identity, verifies integrity and decrypts instantly.
Two pillars of email security
Signing proves who sent a message and that it wasn't altered. Encryption keeps its contents private. Together they secure every email end to end.
Digital signing
Prove every message is genuinely yours.
- Sender authentication, impossible to spoof
- Message integrity, tampering is detected
- Non-repudiation, authorship can't be denied
- Visible trust badge in compatible clients
- Works even with unencrypted recipients
Email encryption
Only the intended recipient can read it.
- End-to-end confidentiality in transit and at rest
- Protects against server-side interception
- Sender keeps a readable copy
- Inline images and attachments encrypted too
- Based on the open S/MIME standard
Control, compliance, trust
Cryptographic email security is more than a feature, it protects your organization, your customers and your reputation.
Regulatory compliance ready
Satisfy encryption mandates across GDPR, HIPAA, ISO 27001 and financial regulations.
Eliminate business email compromise
Spoofed messages visibly lack a valid signature, so BEC attacks fail.
Own your infrastructure
Your CA is fully under your control, govern issuance and revoke instantly.
Scales across the org
Certificate provisioning integrates with user lifecycle, new staff get certs automatically.
Forensic-grade audit trail
Every signed email is a tamper-evident record you can prove in disputes.
Built on open industry standards
No proprietary lock-in, XgenPlus PKI is built entirely on the standards trusted across governments and enterprises worldwide.
S/MIME
RFC 8551.
X.509
ITU digital certificate standard.
RSA
2048 / 4096-bit keys.
AES
256-bit symmetric encryption.
CRL
