PR5: Why choose it

PR5 represents the evolution of the PR4 protocol. 

PR5 is designed to deliver significantly higher throughput than PR4, with average increases of 2–5 times and even higher peaks on large files, while maintaining drastically reduced CPU usage and linear scalability that allows growing workloads to be handled without performance degradation.

With PR5:

• Support for a broader set of encryption and digital signature algorithms compared to PR4
• Architecture designed to be extensible
• Ability to easily and quickly adopt new cryptographic algorithms and updates

Why many customers have chosen PR protocols over open protocols

• Guaranteed interoperability, thanks to protocols designed and certified by Primeur to operate consistently across different products, versions, and platforms, reducing the complexity typical of heterogeneous environments
• Full support for MFT and domain metadata, which are essential to provide context and semantics to transferred files and avoid the need to design complex integration flows, as often happens with open protocols
• Reliable transfer resumption, through native resume and repositioning mechanisms that improve the handling of large files and error scenarios
• Guaranteed delivery, thanks to native features that ensure each file is delivered once and only once (no-loss, no-duplication)
• Integrated mutual authentication, combining server and client authentication to increase connection control and add an additional layer of security

Today, PR5 represents the reference protocol for new implementations and for the evolution of file transfer infrastructures. PR4 remains supported, while adoption of PR5 is recommended for new projects and growth plans.
