Of course, if you don’t find the answer you are looking for you can always ask us. To make sure you’re not wasting your time, let’s start by defining secure file transfer. Then you can be sure the following information will be relevant.

Files are typically sent using HTTP (via a web browser), FTP (client to server) or email. Secure file transfer is when files are transferred using a security protocol to secure that communication channel.

This is incredibly important in corporate environments because organisations are regularly handling personal and sensitive data. Laws like the GDPR and industry standards such as PCI DSS, Sarbanes Oxley and HIPAA dictate an organisation’s responsibility to secure this data. As such, secure file transfer solutions have become a priority for all businesses.

The protocols vary depending on how the file is being sent and received. The key secure file transfer protocols include:

FTPS (FTP run over SSL/TLS)
HTTPS
SFTP (SSH – Secure Shell protocol)

When using the FTPS and HTTPS file transfer protocols, files are sent over a TCP connection. This TCP connection has a TLS (transport layer security) or SSL (secure socket layer) security layer that runs beneath the FTP and HTTP protocols. SSL is a protocol that establishes an agreement between a client/browser and a server. The sending side uses a public key to encrypt a data file, which is then sent using either the FTP or HTTP file transfer protocol. The receiving side will have, as part of the agreement, a unique private key that can decrypt the data file.

SFTP is not just FTP run over SSH. It is a stand alone, dedicated secure file transfer protocol. The file transfer protocol itself does not provide authentication and security; it expects the underlying protocol (SSH) to secure this. SSH is used to establish a connection between a client and server that acts like an encrypted tunnel. This encrypted tunnel protects any data files that are sent via this secure connection.

Enterprise File Sync & Share (EFSS)

Securely send and collaborate on sensitive files, internally or externally, with secure file sharing – also known as a Content Collaboration Platform (CCP), or Enterprise File Sync and Share (EFSS). Learn more about secure file sharing and secure email options below.

Professional Services

A professional services company decided to outsource a particularly large area of its operations: Finance. But without an effective electronic solution, the only way to transfer data to their external provider was to send forms through the post and scan them. This was a time consuming manual process. And with financial data often forming the basis for decisions across the entire business, the data needed to be up to date. Out of date information could have disastrous consequences.

The company implemented a Managed File Transfer solution. This allowed them to securely, quickly and seamlessly move data out to external suppliers for processing, then back into the business.

Public Sector

A local council used Managed File Transfer to move information to third-parties when it couldn’t securely connect via existing government gateways. Files were sensitive, such as reports concerning a member of the public, or a contractual negotiation with a supplier.

Secondly, the solution was used by anyone wishing to send information to the council. Similar to a self-addressed envelope, a council employee could simply send an empty package to the third party, in which they place their documentation before pushing it back securely.

Finally, because users often prefer MFT to email, it was used for the simple and rapid transfer of very large or numerous files to suppliers.

Insurance

Insurance companies need information from their internal users, external customers and suppliers all the time and it is highly likely this will include personal or sensitive data.

It is definitely not appropriate to ask users to share this information over email, but we know that is still common practice for many organisations. Email is not secure, so you risk a breach of the General Data Protection Regulation (GDPR), plus there is no guarantee of delivery. Email cannot support large files either.

Online forms provide a secure, customisable mechanism for your customers, suppliers and internal users to submit information to your business. It is a popular feature of Managed File Transfer systems and can capture any type of information or file size. Fields can also be configured to trigger onward business processes or integrate with internal systems.

Retail

Many MFT solutions have built-in settings to help an organisation configure their systems to be PCI compliant. Reports can be set to check the configuration of the application meets requirements. Whenever a setting is changed in the application that would breach PCI guidelines, it will ask for a reason for the change. This will then be displayed in the compliance report.

By moving data to and from stores and POS systems on an automated schedule, all data can be stored centrally at head office. This provides a better picture of how each branch is performing and adds another layer of security to the data. This automation can also be used to trigger orders when stock levels get low.

NHS and the Healthcare Industry

A medical company wanted to eliminate their reliance on multiple file integration protocols. These were owned by their former parent company. Rather than duplicate the existing complicated systems, they installed Managed File Transfer. This simplified and managed their automated and manual data transfers, whilst providing greater control and a more secure, reliable flow of data. This was particularly important for financial information such as invoices, orders and Bankers’ Automated Clearing Services (BACs) files. Managed File Transfer reduced their reliance on multiple solutions and offered a range of other secure file transfer, automation and reporting functionality.

Secure file transfer is the process of sending data between systems or networks while keeping it safe from unauthorised access, interception, and tampering. It’s crucial for keeping sensitive information confidential and intact during transit. Secure file transfer methods typically use encryption, authentication, and secure protocols to achieve these goals.

The key elements of secure file transfer are:

Encryption: Turns data into a code that only authorised parties can read, preventing unauthorised access during transmission.

Authentication: Verifies that both the sender and receiver are authorised, often using passwords, digital certificates, or multi-factor authentication.

Secure Protocols: Uses protocols specifically designed to protect data in transit, such as:

- SFTP (Secure File Transfer Protocol): An extension of SSH (Secure Shell) that provides secure file transfer.
- FTPS (File Transfer Protocol Secure): An extension of FTP that supports Transport Layer Security (TLS) and Secure Sockets Layer (SSL) protocols.
- HTTPS (HyperText Transfer Protocol Secure): An extension of HTTP that uses TLS/SSL to encrypt data between a web browser and server.

Secure File Transfer is important to organisations and businesses for a number of reasons:

Data Protection: Keeps sensitive data, like personal information, financial records, and intellectual property, safe from cyber threats.
Compliance: Helps organisations meet data security regulations and industry standards (e.g., GDPR, HIPAA).
Trust and Reputation: Protects an organisation’s reputation by preventing data breaches and maintaining trust with clients and partners.

Secure file transfer solutions are essential for businesses and individuals who need to protect their data from evolving cyber threats. By implementing robust secure file transfer protocols, organisations can safeguard their information and ensure secure communication channels.

Secure File Transfer Protocol (SFTP) is a network protocol designed for secure file transfer and remote login over insecure networks. It encrypts both commands and data, ensuring that passwords and sensitive information remain protected during transmission. This makes SFTP a trustworthy option for safely transferring files, as it prevents unauthorised access and data breaches.

File Transfer Protocol Secure (FTPS) is an extension of the traditional FTP that adds support for encryption via TLS (Transport Layer Security) or SSL (Secure Sockets Layer). This ensures that all data transferred between the client and server is encrypted, protecting it from eavesdropping and tampering. By using FTPS, businesses can securely transfer files over the internet, safeguarding sensitive information and complying with data protection regulations.

HyperText Transfer Protocol Secure (HTTPS) is an extension of HTTP that uses TLS/SSL to encrypt data exchanged between a web browser and a server. This encryption ensures that any data sent or received, such as personal information or payment details, is secure from interception and tampering. Widely used across the internet, HTTPS is essential for maintaining privacy and security during online transactions and communications.

As of 2024, HTTPS is the most commonly used secure file transfer protocol. Its widespread adoption across websites for secure data exchange, online transactions, and communications makes it an essential component of internet security. SFTP and FTPS are also widely used, particularly in business environments for secure file transfers, and in Managed File Transfer solutions.

Secure File Transfer - This term broadly refers to any method or protocol used to transfer files securely, ensuring data integrity and confidentiality during transmission.

File Transfer Protocol Secure (FTPS) - FTPS is an extension of FTP that adds support for encryption via TLS (Transport Layer Security) or SSL (Secure Sockets Layer). It secures the data channel, making it suitable for securely transferring files over networks. However, usernames and passwords may still be transmitted in cleartext.

Secure File Transfer Protocol (SFTP) - SFTP is a separate protocol operating over SSH (Secure Shell) and provides secure file access, transfer, and management capabilities. It encrypts both commands and data, ensuring secure transmission and user authentication.

In summary, Secure File Transfer is a general term encompassing various methods for secure data transmission. FTPS adds encryption to traditional FTP, while SFTP operates over SSH, providing a more comprehensive secure file management and transfer solution.

Secure file transfer is primarily focused on moving files from one location to another in a secure manner. This is often used for transferring large amounts of data or sensitive information between systems, organisations, or users.

Secure file sharing focuses on providing access to files for collaboration and sharing among users, often with features that facilitate real-time collaboration and user management. These are also known as Enterprise File Sync and Share (EFSS) solutions or Content Collaboration Platforms (CCP).

FileCloud is an excellent example of a Secure File Sharing solution. It allows users to securely share files and folders with internal and external collaborators. FileCloud provides robust access controls, ensuring that only authorised users can access the shared files. Additionally, it includes features like real-time collaboration, versioning, and detailed audit logs, making it ideal for collaborative environments where multiple users need to access and work on the same files.

Secure Enterprise File Transfer offers several significant benefits to organisations:

Enhanced Security: With secure file transfer systems, your data is protected by encryption and secure protocols, safeguarding sensitive information from unauthorised access, interception, and breaches.

Regulatory Compliance: These systems help you meet industry-specific compliance requirements like GDPR, HIPAA, and PCI-DSS. They provide necessary security controls and maintain audit trails, ensuring you stay compliant with regulations.

Increased Efficiency and Productivity: Automating the file transfer process reduces the need for manual intervention, minimises errors, and speeds up operations. This optimisation allows employees to focus on more strategic and valuable tasks.

Reliability and Integrity: Secure File Transfer solutions ensure that files are transferred accurately and completely, using mechanisms for error checking and correction. This guarantees that your data remains intact and reliable, reducing the risk of corruption or loss.

Greater Visibility and Control: These systems offer comprehensive monitoring, logging, and reporting features. This gives you full visibility into your file transfer activities, allowing you to identify and address potential issues quickly and maintain better control over your data flows.
