Over 130 Million Files Securely Sent via Postbox Annually

In today’s digital landscape, the secure exchange of sensitive data is more crucial than ever. Every year, more than 130 million files are transmitted via Postbox – a testament to the growing demand for solutions that guarantee the safe, compliant, and reliable transfer of confidential information.

This massive number isn't just a measure of activity; it reflects a deeper trend reshaping industries across Europe and beyond: The increasing necessity for secure digital communication – driven by regulatory pressures, the rise of cyber threats, and the growing risks associated with the misuse of data in an AI-powered world.

In addition, the current geopolitical climate has further amplified the call for digital sovereignty. In an era marked by growing concerns over data privacy, international data transfers, and the influence of non-European tech providers, companies are increasingly seeking solutions that ensure their data stays within European borders.

Compliance First: Why Regulations Like DORA Raise the Stakes

One key driver behind the surge in demand for secure file transfer solutions like Postbox is the tightening regulatory landscape. The Digital Operational Resilience Act (DORA), which came into effect in early 2025, exemplifies how seriously operational and cybersecurity resilience are now taken – particularly in the financial sector.

DORA mandates that financial institutions must ensure the integrity, security, and availability of their ICT systems, including how they handle and exchange sensitive data. Secure file exchange isn't a "nice to have" anymore; it’s a core requirement to demonstrate operational resilience, protect customer data, and avoid regulatory sanctions.

Solutions like Postbox provide companies with exactly what’s needed to meet DORA’s stringent demands:

• End-to-end encryption for data in transit and at rest,
• Strict access controls and audit trails,
• Compliance-ready data retention policies,
• and operational transparency around how sensitive information is handled.

Simply securing internal IT systems is no longer sufficient. Today, financial institutions must be able to demonstrate at any time how sensitive data is processed, stored, and exchanged, both within their organizations and with external partners. While this presents significant challenges, it also offers a unique opportunity to strengthen digital infrastructures and build long-term operational resilience.

Our recently published ePaper on DORA explores these developments in depth, offering practical insights for navigating the new regulatory landscape.

The Growing Threat: AI and the Protection of Sensitive Information

At the same time, a new challenge is rapidly emerging: the exposure of sensitive data to AI systems.

With the proliferation of publicly available large language models and AI-powered crawlers, organizations face an unprecedented risk: If sensitive documents are transmitted over unsecured channels or end up on public servers, they can be indexed, scraped, and ingested into AI systems – often without the knowledge or consent of the data owner.

Once confidential data has been absorbed into a large AI model, it's nearly impossible to retrieve or delete it. For businesses handling customer information, trade secrets, financial reports, or regulated data, the consequences can be devastating – from reputational damage to regulatory fines.

Postbox actively mitigates this risk by ensuring that sensitive files:

• Stay protected against unauthorized access through strong encryption and controlled delivery,
• Remain invisible to web crawlers and AI bots,
• and are only accessible to verified recipients within a highly secure environment.

In an AI-driven world, maintaining strict control over where and how your sensitive data is shared is no longer optional – it’s essential.

Conclusion: A Secure Future for Sensitive Data Exchange

As digitalization accelerates, the stakes for secure, compliant data transfer continue to rise. Regulations like DORA are setting a new baseline for what

operational resilience means, while the risks posed by AI require organizations to rethink their approach to data protection.

At the same time, digital sovereignty is becoming a key priority. Organizations increasingly recognize that protecting sensitive information also means controlling where it is stored and who has jurisdiction over it. By choosing European-based solutions like Postbox, companies not only fulfill compliance requirements but also reinforce their autonomy and reduce dependency on non-European providers – a strategic advantage in today's unpredictable global environment.

In this environment, solutions like Postbox don’t just offer convenience – they provide a critical safeguard for sensitive information, business continuity, and regulatory peace of mind.

The number – over 130 million files sent securely each year – is a powerful reminder: organizations are ready to invest in trust, security, and compliance. And with the right partner, staying ahead of regulatory and technological challenges becomes not just achievable, but a competitive advantage.
