The solution has entered the testing phase with its first users. mSzyfr enables encrypted communication between users and the secure transmission of data to the server. It provides comprehensive encryption not only for text and voice messages, but also for audio and video calls.
The mSzyfr communicator is a free tool intended for public administration and for entities within the national cybersecurity system that are registered in the list of key and important entities. In Europe, comparable nationally developed tools of this class currently exist only in France, Germany, and Estonia.
“We are launching tests of a national communicator in which Poland has full control over the data, server infrastructure, and software life cycle. It will be intended for secure communication in public administration and for entities within the national cybersecurity system,” said Paweł Olszewski, Deputy Minister of Digital Affairs.
mSzyfr is the first secure communicator fully under Polish jurisdiction. The servers supporting mSzyfr are located in Poland and are administered by personnel holding the appropriate personal security clearance.
The mSzyfr communicator provides:
- Full digital sovereignty – the organization retains complete control over data, server infrastructure, and the software life cycle in an on-premises model (through deployment of the Element ESS Pro server).
- Integrated end-to-end encryption with advanced cryptography – this guarantees uninterrupted encryption of communication between users and secure transmission of data to the server. Unlike standard communicators, mSzyfr comprehensively encrypts not only text and voice messages, but also audio/video calls, transferred files, and room metadata.
- Decentralization and metadata minimization – the open architecture makes it possible to manage identities and permissions in a way that limits the collection of unnecessary information on the central server. Sensitive data, such as encryption keys, are securely stored on users’ end devices.
- High enterprise-class reliability and scalability – the use of containerization technology ensures system stability, ease of updates, and the ability to scale infrastructure smoothly as the number of users grows, significantly reducing total cost of ownership (TCO).
- Customization and trust – the use of the dedicated mSzyfr application allows full interface customization (branding) and ensures that the application code complies with the organization’s internal security policies.
The mSzyfr communicator is financed from the state budget under the public task entitled Construction of a mobile communications system enabling the processing of classified information up to the “restricted” level (SKR-Z). This task is being carried out by the Scientific and Academic Computer Network – National Research Institute.
