Answers to common questions about the SendSafely platform
SendSafely is an end-to-end encrypted file sharing platform that keeps your sensitive data private and secure throughout the entire transmission process. Unlike conventional file sharing services, SendSafely ensures that data is encrypted on your device before transmission, and that only authorized recipients can decrypt and access it. This approach means that even SendSafely's servers cannot read your data, providing a high level of privacy and security.
SendSafely lets you easily exchange encrypted files and information with anyone on any device. SendSafely works natively with all major browsers. No software to install. No encryption keys to manage. No recipient account required.
SendSafely complies with regulations such as HIPAA, GDPR, CCPA, and PCI, making it suitable for industries with strict data protection requirements.
Seamlessly secure your existing workflows with our native integrations for popular communication platforms such as Gmail, Outlook, and Slack, and customer service platforms such as Intercom, Freshdesk, Zendesk, and Salesforce. Or, easily create your own integration with our developer-friendly API.
SendSafely is enterprise ready with features designed for businesses such as user administration, audit logging, Single Sign-On, and custom branding.
SendSafely originated from Gotham Digital Science (GDS), a security consulting firm that developed the platform to securely transfer files with clients. Due to demand, SendSafely was spun off as a separate company and is now used globally by organizations requiring secure data exchange.
SendSafely employs a robust end-to-end encryption system to ensure the confidentiality and integrity of your data. This system is designed so that only you and your intended recipients can access the information, with even SendSafely unable to decrypt the content.
Encryption Algorithm: SendSafely utilizes the OpenPGP standard with AES-256 encryption. This approach is widely recognized for its reliability and strength in securing data.
Key Generation and Splitting:
Secure Link Sharing: Secure Link Sharing: When you share files, SendSafely generates a secure link client-side (in your browser) that includes the Client Secret embedded within the URL fragment. You send this link to your recipients via an independent third party, such as email, Slack, or support ticket. This fragment is not sent to the SendSafely servers, ensuring that the Client Secret remains confidential.
Recipient Access: Upon accessing the secure link, the recipient's browser combines the Client Secret from the URL fragment with the Server Secret provided by SendSafely to reconstruct the full encryption key. This key is then used to decrypt the files locally in the recipient's browser.
Trusted Device Keys: For users who designate their browsers as "trusted," SendSafely generates a 2048-bit RSA public/private key pair. The private key is stored securely in the browser's local storage, while the public key is uploaded to SendSafely. This mechanism allows for seamless access to received items without compromising security.
By combining these encryption practices and security features, SendSafely ensures that your data remains confidential and secure throughout the transfer process
Yes, you can send files to recipients who do not have a SendSafely account. This is one of SendSafely's core features, designed to make secure file exchange as frictionless as possible.
The recipient does not need to register or log in to access the shared content. As long as they have the secure link and pass the authentication you’ve configured (e.g., SMS verification), they can access the files.
With Sendsafely, there are no file type restrictions. Unlike email systems or antivirus filters, SendSafely does not block files based on type or extension. You can securely send virtually any file using SendSafely, as long as it falls within the platform’s file size limits. SendSafely treats all content as opaque encrypted data.
The maximum file size you can transfer using SendSafely depends on your subscription plan.
SendSafely distinguishes itself from other file transfer tools like Dropbox, Box, or WeTransfer by offering a true zero-knowledge, end-to-end encrypted architecture. Client-side encryption key split (Client Secret + Server Secret) ensures that no external party can access the full key.
Browser-based decryption ensures nothing sensitive touches SendSafely servers in plaintext. This architecture aligns with modern zero-trust principles—a level of protection lacking in most commercial file sharing apps. SendSafely is tailored for strict regulatory needs, with granular security configurations and detailed audit logging. SendSafely is purpose-built for sensitive data sharing in regulated environments.
Additionally, SendSafely recipients don’t need an account. Secure links use a browser-native decryption flow with identity verification (e.g., SMS PIN). Advantage: SendSafely offers a seamless recipient experience without sacrificing security.
