Building Privacy-Focused File Transfer Infrastructure
Our Mission and Operating Principles
SwissTransfer was founded in 2021 to address the growing gap between file transfer needs and privacy protections. As files grew larger and more sensitive, existing solutions forced users to choose between convenience and security. Consumer services offered easy sharing but monetized user data and lacked robust encryption. Enterprise solutions provided security but required complex setup and technical expertise. We built a platform that delivers both security and simplicity.
Our core principle is that privacy is a fundamental right, not a premium feature. Every transfer receives the same end-to-end encryption regardless of file size or user type. We don't offer a "basic" tier with weaker security to upsell premium features. The zero-knowledge architecture applies universally because we believe strong security should be the default, not an option.
Transparency guides our operations. We publish quarterly transparency reports detailing legal requests and security incidents. Our encryption implementation is documented publicly so security researchers can verify our claims. When vulnerabilities are discovered, we disclose them promptly along with remediation steps. This openness builds trust and allows the security community to help us improve.
Swiss jurisdiction was chosen deliberately for its strong privacy laws and political neutrality. Switzerland's history of banking secrecy reflects broader cultural values around confidentiality and discretion. While banking secrecy has evolved under international pressure, data protection laws remain robust. Operating under Swiss law means we're not subject to mass surveillance programs or data retention mandates common in other jurisdictions. Our index page explains how this legal framework combines with technical measures to protect your files.

Technical Infrastructure and Security Practices
Our infrastructure runs entirely on Swiss data centers operated by providers with ISO 27001 and ISO 27018 certifications. These facilities maintain physical security including biometric access controls, 24/7 monitoring, and redundant power systems. Geographic distribution across three Swiss locations provides resilience against localized failures while keeping all data within Swiss jurisdiction.
The technical stack prioritizes security at every layer. Servers run hardened Linux distributions with minimal installed packages to reduce attack surface. All systems receive automated security updates within 24 hours of release. Network segmentation isolates different functions, so even if one component were compromised, attackers couldn't access other systems. Intrusion detection systems monitor for suspicious activity and automatically block potential threats.
Employee access follows least-privilege principles. Engineers can't access production databases directly—all queries go through audited tools that log every action. Customer support staff see only anonymized metadata, never file contents or user identities. Administrative access requires hardware security keys and is limited to specific maintenance windows. These controls ensure that even insiders cannot compromise user privacy.
Regular penetration testing by third-party security firms identifies potential vulnerabilities before attackers can exploit them. The most recent test in October 2023 involved a team of five security researchers who spent three weeks attempting to breach our systems. They found two low-severity issues related to rate limiting and information disclosure, both fixed within 48 hours. The full report is available upon request to enterprise customers conducting vendor assessments. Our FAQ section addresses common security questions, while the main page details our encryption approach.

Commitment to User Privacy and Data Ethics
We collect the minimum data necessary to operate the service. When you create a transfer, we record the upload timestamp, file size, and expiration date. We don't track your IP address beyond temporary rate limiting, don't use analytics cookies, and don't share data with advertising networks. Your email address is only collected if you choose to receive a notification when someone downloads your file—it's never required.
The business model is straightforward: users pay for the service through subscriptions, not through data monetization. Free transfers are supported by paid accounts, similar to how Proton Mail and Tutanota fund their privacy-focused email services. This alignment of incentives means our success depends on protecting your privacy, not exploiting it. We don't need to know what you're transferring or who you're sending it to—we just need to provide reliable infrastructure.
Data retention policies are designed to minimize exposure. Files are deleted immediately upon expiration with no recovery period. Server logs are retained for 30 days for security monitoring, then permanently deleted. Backup systems use the same encryption as production, and backups are deleted on the same schedule as the original data. We don't maintain archives or allow government agencies to install monitoring equipment on our systems.
Looking forward, we're committed to staying ahead of emerging threats. Post-quantum cryptography will replace current algorithms once NIST finalizes standards in 2024. We're researching decentralized storage options that could eliminate central servers entirely. The goal remains constant: giving people control over their data in an increasingly surveilled digital environment. According to the Electronic Frontier Foundation, strong encryption and privacy-preserving design are essential tools for protecting civil liberties online.
