PKI-powered email security that cryptographically authenticates every sender, guarantees message integrity, and ensures only the intended recipient can read what you send — all transparently, automatically.
Four interlocking layers create an unbroken chain of cryptographic trust for every email your organisation sends.
A dedicated CA is established for your organisation's domain — the trusted anchor that issues and manages all user certificates.
Each user receives a unique X.509 digital certificate — a cryptographic identity card binding their email address to a private key only they possess.
Outgoing mail is automatically signed with the sender's private key and optionally encrypted with the recipient's public key — all transparent to the user.
The recipient's mail client validates the certificate chain, confirms the sender's identity, verifies the content hasn't changed, and decrypts — instantly.
A Certificate Authority (CA) is the cryptographic foundation of your email security programme. It acts as your internal "trust notary" — issuing, signing, and managing digital certificates for every domain and user under your control.
Unlike certificates from external commercial providers, an organisational CA gives you complete governance over issuance policies, validity periods, and revocation — with no recurring per-certificate fees.
Digital signing and encryption are complementary — together they make impersonation impossible and eavesdropping futile.
When you send a signed email, your private key generates a unique cryptographic fingerprint of the entire message. The recipient's client verifies this fingerprint using your public certificate — confirming both your identity and that not a single character changed in transit.
The message is encrypted using the recipient's public key before leaving your outbox. Only the holder of the matching private key — the recipient — can decrypt and read it. Even if intercepted at any point in transit, the content is mathematically unreadable.
PKI email security delivers concrete, measurable value at every level — from the individual user to the boardroom.
A verified green badge tells you instantly that an email truly came from the named sender — eliminating impersonation and phishing from trusted colleagues.
Financial data, HR matters, confidential contracts — anything you encrypt is readable only by you and your intended recipient, even if it passes through untrusted servers.
A digitally signed email is legally attributable to you. Recipients — and auditors — can prove you wrote exactly those words, and that nothing changed after you sent it.
Encryption covers the entire message — body, inline images, and every attachment. Nothing travels in plaintext once you click Send.
S/MIME is a universal open standard supported by Outlook, Apple Mail, Gmail (with certs), Thunderbird, and mobile clients — no special plugins required on either side.
Satisfy encryption mandates across GDPR, HIPAA, ISO 27001, and financial sector regulations. Demonstrate due diligence with cryptographic audit trails for every message.
BEC attacks — where criminals impersonate executives or partners — fail completely against signed email. Any spoofed message visibly lacks a valid signature.
Your Certificate Authority is fully under your control. Govern issuance policies, revoke compromised certificates instantly, and maintain complete chain-of-custody — no external dependency.
Certificate provisioning integrates with your user lifecycle management. New employees get certificates automatically; leavers are revoked the same day — at any scale.
Every signed email creates a tamper-evident record. In disputes, investigations, or litigation, you can prove exactly what was sent, by whom, and when — without relying on server logs alone.
No proprietary lock-in. Every component is based on decades of peer-reviewed cryptographic standards.
PKI-grade email security, digital signing, and encryption — built for organisations that cannot afford to get email wrong.
