Enterprise-Grade Encrypted File Sharing for Sensitive Data

01. What encryption standards does MX use for file protection?

My MX Data uses a layered security approach centered around our ASR (Anonymize, Shard, Restore) framework combined with AES-256 encryption, the industry gold standard for data protection. This goes beyond traditional encryption by fragmenting files into anonymized shards and storing them across separate zones – reassembled only when accessed by the intended recipient.

Our encryption model helps businesses stay ahead of evolving threats, including those posed by future quantum computing risks. With ASR, even if one shard is compromised, the data remains unreadable without the complete chain and correct user permissions.

Here’s how MX elevates your encryption strategy:

• AES-256 + ASR Encryption: Combines current best practices with future-proofing for quantum-era threats.
• Encryption at Every Stage: Files are encrypted in transit, at rest, and during sharding and reassembly.
• No Public Sharing Mechanisms: Eliminates exposure risks by removing public links entirely.
• Named-User Decryption: Files are only decrypted when accessed by authorized, verified users.
• Built for Regulated Environments: Supports encryption standards aligned with sectors like legal, finance, and healthcare.

With less than 0.03% of OpenSSH implementations currently using quantum-ready encryption (source), MX stands apart by proactively integrating quantum-resilient design across all file transfers.

02. How is MX encryption different from standard AES-256?

While many platforms rely solely on AES-256 – the current industry standard – My MX Data goes a step further by integrating AES-256 into a layered, quantum-resilient framework known as ASR: Anonymize, Shard, Restore. This proprietary model transforms file encryption from a static lock-and-key mechanism into a multi-stage defense system designed to withstand both current and future threats.

Here’s how MX’s encryption architecture differs:

• Anonymization: File metadata and structure are stripped, removing identifiers that could aid attackers during interception or phishing attacks.
• Sharding: The file is split into multiple encrypted segments and distributed across isolated storage locations, limiting exposure even in the event of partial compromise.
• Restore-on-Request: Only the verified recipient – with correct credentials, location, and access rights – can reassemble and decrypt the original file.

This method not only leverages AES-256 encryption at rest and in transit but adds two additional layers: distributed risk mitigation and endpoint-controlled restoration. It’s designed to counter threats like quantum decryption, credential leaks, and file spoofing – issues often overlooked by traditional tools like Dropbox or Google Drive.

Why it matters: less than 0.03% of platforms currently deploy quantum-safe encryption. MX is already ahead of the curve, giving businesses a futureproof solution for secure file sharing.

03. Can I revoke file access after it’s been shared?

Yes – My MX Data gives you the ability to instantly revoke access to any file, even after it’s been shared. This feature is critical for protecting sensitive information in fast-moving business environments where access requirements can change – such as after a contract ends, a deal falls through, or a stakeholder leaves an organization.

Unlike public file sharing tools that offer little post-delivery control, MX operates on a named-user and session-based model. That means you retain full authority over who can open a file and when – right down to the minute.

Revocation and access controls include:

• Revoke by Recipient: Remove access for one or multiple users without affecting others.
• Revoke by File: Disable downloads or open access for a specific file system-wide.
• Time-Based Expiry: Set automatic expiration windows to restrict how long files remain accessible.
• Download and Open Tracking: Know if a file was accessed before revocation – MX logs every action.

This ensures files remain under your control at all times, making MX ideal for industries like legal, finance, and healthcare where data sensitivity doesn’t stop at delivery.

04. Is there any training required to start using encrypted sharing?

Not at all – My MX Data is built to deliver enterprise-grade encryption with zero learning curve. While the backend applies sophisticated methods like quantum-resistant encryption and data sharding, the user experience is intentionally simple and intuitive.

In fact, most teams can start sending encrypted files immediately after login – no installation, technical expertise, or onboarding required. If you’re familiar with drag-and-drop sharing, you’ll be right at home with MX.

• No Plugins or Software: Everything runs in the cloud via secure web access.
• Guided Interface: Visual cues and tooltips guide users through file uploads, permissions, and delivery.
• Help Center & Support: Step-by-step guides, FAQs, and human support are available anytime.

For teams that require formal onboarding, MX offers optional enterprise training sessions tailored to compliance, security, and role-based access use cases.

05. Does MX offer detailed audit logs for encrypted file exchanges?

We absolutely do! My MX Data provides comprehensive audit logs for all encrypted file exchanges, ensuring your organization maintains full transparency and traceability during every stage of the transfer process. These audit logs are particularly useful for regulated industries and organizations that need to prove chain-of-custody or demonstrate compliance during audits.

Key logging and monitoring features include:

• End-to-End Activity Logging: Track every step in the file lifecycle – from upload, encryption, delivery, and download – alongside timestamps and user identification.
• Access Verification: View logs that confirm which authenticated user accessed a file, at what time, and from which IP address or location.
• Retention and Export Options: Retain logs according to your compliance needs and export them for audits or internal reviews.
• Tamper-Resistant Records: Audit trails are encrypted and securely stored to prevent tampering or loss of forensic integrity.

As Varonis highlights, 9.2% of externally shared files contain sensitive information. With MX, every encrypted transaction is logged and monitored to reduce risk and reinforce control.

With MX, encrypted file sharing doesn’t mean sacrificing visibility – every action is documented to support governance, investigations, and peace of mind.
