Adaptive Secure
Trusted Identity Services
End-to-end encrypted email that works with your existing provider. Secure communication without compromise.
How it works
Seamless end-to-end encryption that integrates with your existing email workflow.
Your email provider never sees plaintext. ASTIS stores encrypted SKEY capsules while SMTP only transfers encrypted messages.
Compose
Write your email in your favorite client - Outlook, Thunderbird, or any email app.
Encrypt & Sign
ASTIS automatically encrypts and signs your message with end-to-end encryption.
Store Session Key
Session keys encrypted with OpenPGP are stored with policy controls and TTL for secure access management.
Recipient Decrypts
Only the intended recipient can decrypt the message using their private key.
Audit & Logs
Track SKEY usage per user: how many session keys generated, access frequency for sent/received messages.
Key benefits
Enterprise-grade security without the complexity. Protect your communications with confidence.
Encryption & Digital Signatures
OpenPGP-based encryption and digital signatures ensure message confidentiality and authenticity. Verify sender identity and detect tampering.
Works with Existing Email
No need to change email providers. ASTIS integrates seamlessly with Outlook, Thunderbird, and more.

ASTIS does not replace your email provider. Keep Gmail/Microsoft/SMTP for delivery — ASTIS adds encryption key control, TTL, policies, and audit.
Compromised mailbox ≠ readable content. Protected messages remain unreadable without controlled decryption.
