PeSIT transfers
Data exchanges with PeSIT
PeSIT (Protocole d’Échange Standard Interbanques de Télétransmission) is a file transfer protocol that enables files to be written and read from one machine to another. PeSIT supports a variety of communication modes, including point-to-point and point-to-multipoint, meeting the diverse operational needs of the banking industry.
The PeSIT protocol and the financial sector
Developed by the GSIT (Groupement des Systèmes Interbancaires de Télécompensation) in the 1980s, PeSIT is a protocol originating from the French banking profession, which aims to facilitate secure data exchanges between banks and financial institutions, providing a standardised method for transmitting financial data securely via telecommunications networks.
The PeSIT protocol also plays a crucial role in the insurance and healthcare sectors. PeSIT ensures the secure and efficient transmission of sensitive data, such as medical records and patient information, between institutions.
This secure transfer mechanism is essential for maintaining confidentiality, supporting the smooth integration of systems and helping to streamline administrative processes.
Its key features include data integrity, encryption and reliable delivery, making it suitable for the sensitive nature of financial transactions.
PeSIT offers features to ensure the reliability of data exchanges, including integrity verification mechanisms. It guarantees message delivery and can handle transmission errors effectively.
The PeSIT protocol incorporates robust security mechanisms to guarantee the confidentiality, integrity, mutual non-repudiation and authenticity of data exchanged between banking institutions. It uses TLS encryption and certificate authentication techniques to secure communications.
- PeSIT is considered to be a unique, but complex protocol compared with other file transfer methods. The PeSIT protocol allows only one file to be transferred at a time during a session, but several files can be transferred simultaneously if several sessions are open
PeSIT protocol features
This function allows a PeSIT protocol user to transfer the contents of a file to another user who also has PeSIT.
To do this, the sending user must first establish a logical link, called a connection, with the other user.
The user who initiates this connection is called the Requester, while the other user is called the Server. In this context, the transfer of file data takes place between the Requester (sender) and the Server (receiver).
This function allows a user of the PeSIT service to ask another user of the same service to transfer the contents of a file. To do this, the user wishing to receive the file must first establish a logical connection with the other user.
The user making the request is referred to as the Requester, while the other user is referred to as the Server. In this configuration, the transfer of file data takes place between the Server (sender) and the Requester (receiver).
IT solutions based on the PeSIT protocol can manage flow control to regulate the flow of data exchanged between partners. This optimises network performance and prevents saturation. However, this functionality is highly dependent on the solution used.
The PeSIT protocol is designed to be compatible with different types of computer systems and networks, facilitating integration and interoperability between the different platforms used.
PeSIT offers features for managing data formats, enabling data to be automatically converted into the appropriate format when exchanged between partners.
This facilitates systems integration and reduces the complexity of data exchange processes.
In some IT solutions on the market, this function allows a user to interrupt a transfer in order to reuse the connection for a higher priority transfer. The suspended transfer will be resumed at a later date.
The data sender can insert sequentially numbered synchronisation points during the transfer. The receiver can confirm receipt of these points, indicating that it has correctly stored the data up to that point. This enables a transfer to be resumed from a point other than the beginning of the file in the event of an incident.
In the event of an incident during data transfer, a user can ask his partner to resume the transfer from an earlier synchronisation point.
Unlike resumption, which takes place after the transfer has been interrupted, resynchronisation takes place while the file remains open and selected.
Here is a list of the key features of the PeSIT protocol. Some features are only accessible with a file transfer solution that will unleash the full potential of exchanges.
Modernising your PeSIT file transfers
Upgrade your PeSIT exchanges to more intuitive, reliable, cost-effective and secure management!
- Manage your PeSIT transfers via an intuitive platform
- Improve the productivity of your teams
- Optimise your costs
- Strengthen your security and regulatory compliance
- Add other protocols (HTTPS, SFTP, etc.) to centrally manage all your file transfers
GoAnywhere MFT solution can connect to PeSIT servers. GoAnywhere MFT ensures the delivery of PeSIT transfers with options to automatically restart connections, resume interrupted file transfers, and verify the integrity of successful file transfers.

PeSIT protocol with compliance
In sectors where regulatory compliance dictates the use of specific protocols, or where legacy systems remain entrenched, PeSIT continues to be a popular and in-demand protocol. Organisations with established infrastructures built around PeSIT can choose to maintain support for the protocol to minimise disruption and avoid costly migrations.
PeSIT’s robustness and reliability in processing large volumes of transactions makes it suitable for mission-critical applications where data integrity and consistency are paramount. In environments where real-time processing is not a requirement, the desynchronised nature of PeSIT can be advantageous, enabling batch transfers and optimised use of resources.
PeSIT is a robust and proven protocol that is sometimes complex to implement in line with today’s cybersecurity requirements.
