Secure email, files, and collaboration.
Encrypted by policy.
TerraZone's Secure Information Exchange is a product family - policy-driven encryption for email, managed file transfer, and collaborative file sharing. Recipients access encrypted content through identity-based authentication, no software installation required.
Built for.
Email: the most common - yet most vulnerable channel.
Email is the primary method of business communication, but it is also one of the biggest risks for data breaches, unauthorized access, and regulatory violations. Without encryption, sensitive business data can be intercepted, leaked, or exploited by malicious actors.
Emails often contain sensitive business data, financial information, and confidential attachments - making them a primary target for data breaches, phishing attacks, and compliance violations. Without automated classification and encryption enforcement, organizations risk accidental data leaks, unauthorized email forwarding, and exposure of sensitive content.
The same risk extends to managed file transfer and collaborative file sharing. Files moved between organizations, contractors, and partners cross multiple uncontrolled environments. Traditional methods - email attachments, public cloud storage, FTP servers - lack granular access control, encryption, and visibility.
Four ways sensitive data leaves your control.
If you recognize one or more of these in your organization, the problem isn't your people - it's that the tools they were given were never built to keep control of a file after it's sent.
Once it's sent, it's gone
Standard email hands over a copy and ends your authority over it. The recipient can forward it, print it, save it to a personal device, or keep it long after the project closes. There is no recall, no expiry, and no way to know where the document ended up.
Shadow channels fill the gap
When the sanctioned path can't carry the file - too large, too slow, blocked by policy - people find one that can. Personal WeTransfer links, consumer cloud drives, WhatsApp, a USB stick. The data leaves the organization entirely, and nobody logs it.
Encryption without identity
A password-protected archive or an encrypted attachment protects the file in transit and stops there. Whoever holds the password is treated as authorized - including the wrong recipient added by autocomplete, or an attacker who reached the mailbox. Encryption proves the content is sealed, not who opened it.
No evidence when it matters
Regulators and auditors ask a specific question: who accessed this record, when, and what did they do with it. Mail servers, FTP logs, and file shares each answer a fragment in a different format -reconstructing a single chain of custody becomes a manual project every audit cycle.
Sending is not the same as sharing. Every traditional channel is built to hand over a copy and stop tracking it - which is why control ends at the moment of delivery, exactly when the regulation says it should begin. Secure Information Exchange closes that gap - the recipient gets access to the content, not custody of it, with permissions, expiry, and revocation that stay enforceable after delivery.
Three layers. One policy-driven engine.
Secure Information Exchange combines automated content classification, dynamic encryption enforcement, and identity-based recipient access - all without disrupting how users send and receive information.
Policy-Driven Encryption & Content Classification
Encryption applied automatically - based on what's inside.
It automatically classifies emails, attachments, and files by analyzing body content, subject lines, and metadata. Encryption is then applied dynamically - based on content sensitivity, recipient identity, and predefined security rules. No manual action needed from senders.
Data is protected with AES 256-bit encryption in transit and at rest, ensuring confidentiality across every stage of the communication lifecycle. Files never remain in unsecured storage or DMZ environments.
- AES 256-bit encryption — in transit & at rest
- Policy-based encryption enforcement
- Automated content classification
- Dynamic rules based on sensitivity
Identity-Based Recipient Authentication
Recipients access encrypted content - without installing anything.
Encrypted messages and files are delivered via an intuitive, authentication-based portal. Recipients verify identity through OAuth2 (Live ID, SAML), One-Time Password (OTP), or domain-based policies - no software installation, no decryption keys to manage.
Senders maintain full control: restrict downloads, prevent forwarding, set expiration dates, and revoke access - even after the message has been delivered.
- OAuth2, SAML, OTP recipient authentication
- Granular access controls per message
- No software installation required
- Expiration & revocation after delivery
Audit Trails & Regulatory Compliance
Every action logged. Every regulation covered.
It logs every interaction - email opens, file access, downloads, forwarding attempts, expiration events - providing complete forensic visibility for security investigations and compliance audits.
Built-in policy enforcement helps organizations meet GDPR, HIPAA, PCI-DSS, and ISO 27001 requirements out of the box. Compliance reporting is automated, exportable, and ready for legal archiving.
- Full audit trails on every action
- Automated compliance reporting
- GDPR, HIPAA, PCI-DSS, ISO 27001 ready
- Real-time activity monitoring & tracking

One engine behind every channel.
All four solutions run on the same policy, encryption, and audit engine - so a rule written once applies whether the data travels as an email, an attachment, a managed transfer, or a shared vault. One console, one policy model, one chain of custody.
Content is classified automatically from the message body, subject line, and attachments, and the matching policy is applied before anything leaves the organization. Users don't have to remember which rule applies - the engine decides, consistently, every time.
Data is encrypted at rest, in transit, and on delivery, with keys held under organizational control rather than by the recipient's mail provider. Encryption follows the content into the vault, not just across the wire.
Access is tied to a verified identity, not to possession of a link or password - via OAuth2, one-time passcode, or domain-based policy. The wrong recipient added by autocomplete cannot open what wasn't meant for them.
Permissions remain enforceable after the send: set expiry dates, revoke access retroactively, and grant view-only rights that block forwarding, downloading, and printing. Delivery transfers access, never custody.
See when a message is opened, by whom, from where, and what they did next - downloaded, printed, or attempted to forward. Delivery confirmation tells you a file arrived; activity tracking tells you what happened to it afterwards.
Documents can be watermarked per recipient at the moment of access, so any screenshot or photograph carries the identity of whoever leaked it. Rights management keeps usage rules attached to the content itself rather than to the channel it travelled through.
Works inside the mail client people already use, with the Connector SMTP gateway applying policy centrally for enterprise applications and automated systems. Security that requires no change in behavior is security that actually gets used.
Scheduled, policy-driven transfers for A2A, B2B, and U2U flows, at volumes email cannot carry. Files move directly between endpoints - never parked in unsecured storage or left waiting in a DMZ - so automation replaces the manual FTP scripts nobody documented.
Runs on AWS, Azure, Google Cloud, or entirely inside your own data center, including fully isolated environments. The same policy engine enforces the same rules wherever it sits - deployment model is an infrastructure decision, not a security compromise.
Every send, open, download, and revocation is logged per identity across all four channels and exported to SIEM. One chain of custody instead of four fragmented log formats - audit-ready for GDPR, HIPAA, PCI DSS, and ISO 27001.
Three outcomes that start on day one.
Send Sensitive Email Under Policy
Classified content is encrypted, authenticated to a verified recipient, and stays revocable after it lands. Users keep working in Outlook exactly as before - the policy engine decides what protection applies, so compliance stops depending on anyone remembering the rule.
Get startedReplace Consumer File Sharing
Large files reach partners and customers through a controlled, fully logged channel instead of WeTransfer links and personal cloud drives. The recipient gets access to the content, not custody of it - with expiry dates, view-only rights, and no download when policy says so.
Get startedAutomate B2B and Machine Transfers
Recurring transfers between applications, partners, and systems run on schedule under a single policy, with no manual FTP scripts and no files left waiting in a DMZ. Every transfer produces the audit evidence a regulator asks for, without anyone assembling it by hand.
