Representatives of NIX.CZ Association and the Slovak cyber-security team CSIRT.SK sign a memorandum on cooperation

The representatives of NIX.CZ Association, which runs the neutral peering node for the Czech Republic, and the Slovak national cyber-security team CSIRT.SK have signed a memorandum on cooperation. The two organisations will be cooperating primarily in the field of network security. Since March 2015, NIX.CZ Association has been running the Slovak peering node NIX.SK, which is one of the two internet exchange points in Slovakia. An additional area of cooperation is related to the FENIX security project, whose aim is to ensure that Internet services provided by the participating subjects remain available in the case of a DoS attack.

“The main goals of NIX.CZ Association are to operate Internet peering nodes and raise public awareness, especially around issues of network security. In the Czech Republic, we have been working very well together with the CSIRT.CZ security team, especially as part of various working groups. We would like to bring this successful form of cooperation to Slovakia,” said the Director of the Association Martin Semrád. „Among others, our Association would also like to offer the companies connected to the NIX.SK peering node to participate in the Slovak version of the FENIX security project. One of the conditions is having a dedicated security team -- the CSIRT.SK specialists can be a big help in creating one.”

“One of the main tasks of CSIRT.SK is to constantly improve the level of security of the Slovak digital space. We are trying to provide our clients with active and proactive services, which aim to secure the availability of the systems even in the case of large-scale attacks, by having a coordinated response to incidents on the national level. The FENIX Project has the potential to significantly aid our clients in securing the continuity of their services. We therefore welcome the initiative of NIX.CZ to bring this project to Slovakia and will be very happy to support it. The initiative will contribute to the building of the Internet security community in Slovakia,” said Petra Hochmannová, the Director of the Slovak special unit for solving computer security incidents CSIRT.SK.


CSIRT.SK (Computer Security Incident Response Team Slovakia) was founded by the Slovak Ministry of Finance. Its mission is to ensure an adequate level of security for the national information and communication infrastructure and critical information infrastructure. CSIRT.SK is also responsible for resolving security incidents and helping to deal with their consequences. These activities are carried out by working together with telecommunication operators, Internet service providers (ISP), other service providers and national authorities. In addition, CSIRT.SK works to raise awareness in the field of internet security; the unit actively cooperates with foreign organisations and represents Slovakia on the international information security scene.

About NIX.CZ Association

NIX.CZ Association brings together Czech and foreign Internet service providers for the purpose of interconnecting their networks. The association is currently the largest neutral IXP (Internet Exchange Point) in the Czech Republic and one of the ten largest IXPs in Europe.

Since 2003, the association has also been supporting Internet peering via the IPv6 protocol.

About the FENIX Project

The FENIX Project was founded by the Czech peering node NIX.CZ in 2013, as a reaction to a series of intense DoS attacks, which targeted a number of significant Czech media, banks and service operators in March 2012. The aim of the project is to guarantee that the services offered by the participating subjects remain available in the event of another DoS attack.

The FENIX Project is managed by its members themselves. These are independent of NIX.CZ Association and have absolute autonomy in decision making. The Project is aimed at companies who offer internet connection to key services and require that their functioning is guaranteed even in the most critical situations.

SITELiX Project replaced by NIX.SK: The Czech peering node enters the Slovak market

Bratislava/Prague, 18th March 2015 -- In early January, the Czech Republic’s neutral peering node NIX.CZ announced that it was taking over the running of the SITELiX project, one of the two peering nodes currently active in Slovakia. During today’s Peering Day conference in Bratislava, the Director of NIX.CZ Martin Semrád introduced several new initiatives connected with this move. They include expanding the offer for Slovak networks, a new name (NIX.SK) and the launch of the Route Server service, previously lacking on the Slovak market. All details are available on the website:

The NIX.SK Project (previously SITELiX) remains a neutral peering node dedicated to Slovakia and will not be interconnected with the Czech peering node. NIX.CZ Association will be running the node from Prague, while maintaining a separate organizational unit in Bratislava, mostly for tax-related and administrative reasons.

“Today marks the end of the SITELiX Project and the beginning of NIX.SK. The similarity of the name with NIX.CZ is no coincidence – we would like it to reflect the values and the vision we have been developing in the Czech Republic for more than 18 years. Another important news is the launch of our new Route Server service, which will facilitate creating peering connections for new member companies. We are also expanding the NIX.SK offer to include 100 Gb connections. No such high-capacity connection had previously been available in Slovakia,” said Martin Semrád, the Director of NIX.CZ Association, which runs the NIX.SK peering node.

The Slovakian interconnection market acquires a strong new partner with abundant experience in data transfer between Internet operators. NIX.CZ is also hoping to bring new international content providers to Slovakia, which are currently active in the Czech Republic and elsewhere, in order to improve their interconnections with Slovak networks.

More information about the NIX.SK Project is available on or in the press release announcing the expansion of NIX.CZ to the Slovak market published in January of this year, which can be found in the News section of the Association’s website.
