Encrypted File Sharing When Stored On The Server Or In The Cloud

ENCRYPTION WITHOUT WORKFLOW DISRUPTION
A frequent source of frustration for users is workflow disruption caused by competitors’ encryption solutions, mainly because they rely on a “Key Management System (KMS)” that makes encryption complex and time-consuming. Users need to request encryption keys from a vault, manually encrypt the file, and store the key for later decryption. These competitors’ systems have no provisions for sharing encrypted files when they are stored on a local central server or in a cloud service.
Here's how TeraCryption differs:
No key fetching, no key vaults, no KMS to maintain.
TeraKey automatically generates a new, unique encryption key for every file, and that key is never reused and never stored.
There are no encryption keys embedded in the file, and none are sitting in a database for attackers to find.
The Key Management System adds cost, complexity, and operational risk. TeraKey eliminates this entirely. Key management is automated, invisible, and secure by design. Files are encrypted in seconds, with zero user involvement in the encryption key management operation and no consequential workflow interruption.
ENCRYPTED FILE SHARING—WITHOUT EXPOSING KEYS
There is no point in encrypting files if they cannot be shared, and this is where many competitors’ platforms fail to make it easy:
Some systems cannot send encrypted files outside their server because the encryption key cannot be safely extracted.
Others require users to send decryption keys separately—often by email—which introduces obvious risk.
With TeraCryption
Users select which authorized users or groups can decrypt a shared folder.
No encryption keys are sent, copied, or managed by users.
Sharing permissions are applied with a single click.
Administrators can fully control or restrict sharing at the user or group level.
TeraCryption integrates directly with Windows Explorer, so if users know how to use Explorer, they already know how to use TeraCryption. There is no new UI to learn, which significantly improves adoption.
FULL VISIBILITY AND AUDITABILITY
Tracking encryption and decryption activity is essential for file security and encryption control. TeraCryption provides detailed logs that show:
Who encrypted or decrypted a file and when.
Unauthorized access attempts.
File modifications and deletions.
This audit trail provides continuous visibility into how sensitive documents are accessed and used, helping you maintain control and demonstrate compliance with security and file user permissions.
STORAGE MODELS: PLAN 2 VS. PLAN 3
Please read about our subscription plans HERE.
Plan 2 — Cloud-Based Encrypted Storage
Plan 2 is ideal for teams that prefer cloud storage for encrypted files.
TeraKey automatically encrypts, uploads, downloads, and decrypts files when using storage cloud services.
Performance depends mainly on Internet bandwidth and the cloud provider.
Ransomware resilience.
If an attacker compromises endpoints and encrypts local systems, users can reinstall TeraKey and access the encrypted files stored in OneDrive, Google Drive, or an Amazon S3 bucket. Operations resume quickly. Isn’t that what we all want in case of trouble? A fast recovery?
Plan 3 — On-Premises Server Storage (No Cloud Storage Dependency)
Some organizations, due to internal security policies, prefer not to store encrypted files in the cloud. Plan 3 addresses this by:
Storing encrypted files in a dedicated folder on your server. i.e.: TK-SERVER.
Integrating TeraKey to use shared group folders inside the TK-SERVER.
This eliminates the need to expose or share the server folder with users.
Only authenticated TeraKey users can see the shared encrypted folders in their Explorer. To open an encrypted file, users double-click it, edit it (for example, in Word), and when they close the application, the file is automatically re-encrypted and saved back to the server.
No one outside the authorized TeraKey group can decrypt these files.
REAL-TIME AUTOMATED BACKUP OF FILES IN THE SERVER WHEN USING PLAN 4 (RANSOMWARE PROTECTION)
Although this functionality is part of Plan 4, it is often a key factor in Plan 3 decisions. With the TeraBackup component installed on the server:
All encrypted files in TK-SERVER are mirrored in real time to a cloud storage service.
Any file changed by a TeraKey user is automatically backed up to the cloud.
SQL database backups (.bat) can also be automatically encrypted and backed up to the cloud storage.
If a server is compromised or ransomware strikes, encrypted files can be restored without data loss up to the moment of the attack.
PROPOSED NEXT STEP: RISK-FREE PROOF OF CONCEPT
We offer a 7-day free Proof of Concept (POC) with full functionality, at no cost or obligation. Our support team can assist your team with installing TeraKey. It usually takes about an hour in a Zoom online meeting. The POC will allow you and your team to validate:
Workflow impact.
Security posture.
Performance.
Administrative visibility.
EVALUATION AND COMPARISON
We can create a functionality comparison table if you provide the names of our competitorsyou are considering. We usually do this work at no charge. The comparison document will save you time and provide a clearer understanding of the advantages and benefits of TeraCryption.
Please let me know your goals, concerns, and file security risks you would like us to address.
BOOK A DEMO
Give us 30 minutes to demonstrate Terakey's operation to you and your team at a time and date that suits you, and we'll send a Zoom invitation.
You can book your demo HERE.
We believe a short demo will quickly show why TeraCryption takes a fundamentally different and more straightforward approach to Encrypted File Sharing.
Let TeraCryption protect your organization’s most sensitive files.
