MailSPEC Unveils PassLink: Revolutionizing Secure File Sharing to Safeguard Data Sovereignty

San Francisco, CA – October 1, 2025

MailSPEC, a leader in compliance technology for communications, today announced the launch of PassLink 2.0, an innovative encrypted file-sharing tool designed to protect the sovereign integrity of sensitive data. In an era where data breaches and unauthorized surveillance pose constant threats, PassLink empowers organizations to share files securely without compromising jurisdictional control or exposing information to external risks.

PassLink addresses a critical challenge, especially so for Regulated Industries that are restricted from transporting sensitive data beyond national borders or jurisdictional boundaries. By enabling the creation of encrypted links for file access, it ensures that proprietary or confidential information remains under the sender's control, even when transmitted through potentially vulnerable channels. Recipients authenticate with their existing identity (Microsoft, Google, or OTP). This is particularly vital for sectors such as defense, finance, and government, where regulations prohibit data from leaving territorial confines to prevent espionage, compliance violations, or loss of sovereignty.

In healthcare, for instance, PassLink allows providers to securely share patient records, medical images, or treatment plans directly with individuals. Files can be shared via everyday email services such as Yahoo, Gmail, or Office 365; platforms hosted on global cloud systems that often scan content for user profiling, advertising, or other nefarious purposes. With PassLink, files are strongly encrypted end-to-end, rendering them inaccessible to intermediaries or unauthorized parties. The services are self-hosted, placed in a private cloud, national cloud, or on-premises of the enterprise. This means healthcare professionals can maintain patient privacy and comply with data sovereignty requirements, all while using familiar, convenient communication tools without the need for outsourcing to vulnerable shared infrastructure.

"PassLink is a game-changer for organizations navigating stringent data

protection laws”, said Tanguy Godquin - PhD, Research & Development director at MailSPEC. "It eliminates the burdens of traditional secure file transfer methods, offering seamless integration that meets policy requirements without added complexity."

Key to PassLink's appeal is its robust compliance framework. The solution supports adherence to major international regulations, including Japan's Act on the Protection of Personal Information (APPI), Europe's Markets in Financial Instruments Directive II (MiFID II), and the U.S. Securities and Exchange Commission's Rule 17a-4. Businesses can remain compliant with these policies, ensuring data retention, auditability, and privacy, while avoiding operational hurdles, such as restricted workflows.

PassLink's features include:

• Advanced Encryption: Files are protected with military-grade encryption, a forward safe feature to prevent unauthorized interception, reception confirmation receipt, and SDK for data rooms and hardware-based identity platforms.

• Sovereignty Controls: Shared data never leaves the originator's jurisdiction unless explicitly authorized, preserving national integrity.

• User-Friendly Integration: Compatible with most leading email or messaging platforms, reducing training needs and enhancing productivity.

• Audit Trails: Comprehensive eDiscovery for regulatory reporting, without compromising usability.

• Revocation & Expiry: Senders can revoke access or set expirations at any time, maintaining full lifecycle control over shared data.

• Robust SDK: Available in Office365, web client, or code for billing, patient management systems, and banking self-care portals.

Available now, PassLink is poised to transform how Regulated Industries handle file sharing. For more information or to schedule a demo, visit
