Through the National Telecommunications Backbone Network we provide VoIP services with call options towards public telecommunication networks.


We oversee and handle the IT background required for the operation of central governmental institutions. The former island-like IT structures gradually undergo a step-by-step process of transformation and merge into a centralized IT system, supporting the ongoing nationwide consolidation of the governmental IT and telecommunication services.

Within the framework of these services, we are in charge of the procurement of IT devices, full-scale device management, we support the relocation of users and we make sure that the various devices are upgraded whenever it becomes necessary.


The National Telecommunications Backbone Network was designed and constructed with the specific requirements of the government and public administration in mind. The high availability-rate of the backbone network is ensured by several redundant optical rings. 


The Government Cloud is a dedicated cloud-environment developed for the Public Administration. Its services allow clients to use cost effective, high availability servers running on modern, fault tolerant infrastructure. The Government Cloud complies with data security requirements laid down in Act No. L of 2013. 

It provides the institutions with cloud-based IT infrastructure services (IaaS - Infrastructure as a Service)  


Mobile networks and web applications provide new means of communication. The development and implementation of public electronic services are top priorities in Hungary.

e-Public Administration Services

Laying down the foundations of a modern e-public administration has been an on-going process. The recent years have seen development projects making several e-services available for citizens, enterprises, and public authorities. However, the current range of services is yet to be extended and introduced to users. NISZ has been playing a strategic role in enabling e-public administration services in Hungary. 

By using various services, users most often meet the following three functions of the e-public administration infrastructure: 

  • identification and authentication 
  • digital signature 
  • documents delivery 

Due to the new technologies, already known from the private sector (e.g. from private banking), user-friendly, high quality e-services and security solutions will be introduced in the public administration as well.

Central e-Government Portal is the national e-Government Portal, a starting point for citizens and businesses to access online public administration (information, search facilities and transactional e-government services) provided by public authorities. 

Users browsing the portal may fully carry out electronic transactions, they can arrange appointments with authorities, apply for an account to the Citizen’s Portal, initiate procedures, and have messages from the authorities delivered to them. 

Monthly page views at the domain exceed 20 million, whereas the number of unique visitors is 600 thousand. Two thirds of the visitors exhibit no referrer page, thus a broad awareness of the portal can be assumed. /

Citizen’s Portal 

The Citizen’s Portal is the primary point of electronic access and identification   available for clients within the system of Hungarian public administration. Citizen’s Portal, an independent service, authenticates its users to safely get in touch with authorities that provide e-government services. Any natural person may register one or more Citizen’s Portal accounts (the first one being free of charge). Those under 18 may access a limited range of services only, like application to higher education institutions. For those who login to the Citizen’s Portal, some 300 e-services become accessible, the most popular being tax and social insurance declarations, university applications, personal document related services, land registry enquiries, and request for a Certificate of No Criminal Record.

Central Client Authentication Agent (CCAA) 

CCAA allows access to the Hungarian e-government services with online identities other than the incumbent Citizen’s Portal accounts. The service is free of charge and provides a single point of access to all authentication services recognized by the state. Its interface shall facilitate, and thereby reduce the costs of adopting a wide range of identity services for public service providers. 

The Central Client Authentication Agent operated by NISZ is to accomplish that government and market identity services shall be handled on equal terms. Licensing the solutions of private identity providers (including banks, global e-mail service providers, and social media companies) will make e-public administration more accessible to everyone.

Government Certification Services

Signature certificates

Regarding certificates facilitating digital signatures (whether for employees or organizations, humans or machines, compliant or not with requirements for administrative procedures), NISZ follows common market practice by assuming limited financial liability depending on the transaction size limit chosen for each certificate.

Certificates for advanced digital signature facilitate digital signatures which are advanced (non-qualified) by the degree of data security, are linked to a certain person, organization or device, and are capable of identifying the signatory. They warrant that a signed document is authentic and has not been tampered with, and also fulfil the legal prerequisites of written communication. 

Certificates for qualified digital signatures may be either advanced or, through application of a Secure Signature-Creation Device, chip card or USB token, qualified. They warrant that a signed document is authentic and has not been tampered with and, surpassing advanced certificates’ features, fulfil the legal requisites of affidavits and are thus eligible to replace manual signatures in most contexts. Clients may also opt for qualified certificates allowing the use of digital signatures in administrative procedures and services.


Cryptographic certificates ensure the confidentiality of communication or the encryption of confidential documents. In case a private key goes missing, a key restoration service is also available. 

To obtain an organization level cryptographic certificate for VPN-s, clients may choose to bring their own private keys. 


Authentication certificates facilitate the identification of employees (e.g. for remote access to the Client Gate system), organizations or servers. 

To obtain an organization level SSL certificate, clients may choose to bring their own private keys. 


You can subscribe to certificates at NISZ Customer Services Office during business hours. To obtain certificates for natural persons, clients are required to present their ID cards. For certificates for organizations (or their employees and/or VPNs), applicants need to submit a copy of the company register or the articles of incorporation (neither older than 30 days) and a specimen signature.


The Identification Based Document Authentication (IBDA/ service offers a comfortable solution for public authorities, citizens and businesses to safely conduct their official transactions even if they lack any authentication tool like a certified digital signature. IBDA ensures that clients who are properly identified (typically through the central Citizen’s Portal service) fully engage electronic public administration even if the procedure would require the submission of digitally signed documents. 

On one hand, IBDA can directly connect to IT systems delivering public services. Citizen or business clients seeking such service will need to visit the portal of the public authority, have themselves authenticated (e.g. via the Citizen’s Portal), then manage and submit (or upload, in certain cases) relevant documents. The authority then calls the IBDA service which will append a clause (or footnote) to the document, comprising a unique authentication code, organization signature and a timestamp. IBDA also allows mass submission of documents, typically through the authentication of clients like accountants, representing a number of applicants. 

Optionally, IBDA can also be reached by citizens through its own website. Thus, anyone with a browser, internet access, and a Client Gate account can access the service. This solution is of great use if a document or statement to be submitted requires a proof of authenticity which the applicant cannot obtain otherwise. However, the stand-alone IBDA service also depends on services or workflows accepting such certification. The first compatible procedures will be soon featured by all Public Service Desks (integrated, personal customer service points of the public administration), optionally utilizing public service assistants as clients to be authenticated on behalf of applicants. You can subscribe to certificates at NISZ Customer Services Office during business hours. To obtain certificates for natural persons, clients are required to present their ID cards. For certificates for organizations (or their employees and/or VPNs), applicants need to submit a copy of the company register or the articles of incorporation (neither older than 30 days) and a specimen signature.
