What CESNET does

CESNET, zájmové sdružení právnických osob, is a Czech non-profit association founded on March 13, 1996, that operates the national academic and research computer network. Its members are all Czech public universities and the Czech Academy of Sciences, and CESNET serves approximately 250 institutions and 450,000+ end users across the country. The organization is headquartered in Prague and runs additional technical operations including data centers in Ostrava.

CESNET delivers an integrated e-infrastructure platform built around six core service areas: (1) Network Services operating the CESNET3 backbone — a high-speed, low-latency optical network with international connectivity (400 Gb/s uplink to GÉANT as of July 2025), specialized non-IP capabilities including Quantum Key Distribution (QKD), precise time transmission, and frequency distribution; (2) Computing Services anchored by MetaCentrum, the Czech National Grid Infrastructure and official component of the European Grid Infrastructure (EGI), providing ~41,288 CPU cores across HPC clusters and cloud platforms; (3) Data Storage based on Ceph object storage distributed exclusively across Czech data centers with 120+ PB capacity; (4) Security services including network scanning and the Phishingator phishing-protection tool; (5) Multimedia collaboration (Meetings video conferencing up to UltraHD); and (6) Identity services via the eduID.cz federation and a Perun-based Authentication and Authorization Infrastructure (AAI) used by international and national research infrastructures. Adjacent services include FileSender, ownCloud, and Zoom SSO integration.

Commercially, CESNET is a non-profit whose primary revenue mechanics are member contributions from Czech universities and the Academy of Sciences, supplemented by government subsidies (referenced at billion-CZK scale in 2025) and supplementary commercial activities — voice services, circuit rental, data transmission, internet access, consulting/training, and resale — used to transfer research results into practice. The go-to-market is community-led and direct: services are accessible to individual students, scientists, researchers, and academics at member institutions through a Virtual Organization / Perun IdM access layer, with no intermediary resellers. Distribution is single-country (Czech Republic), with international reach channeled through partnerships with GÉANT, EGI, eduroam, and similar European research-e-infrastructure bodies.

Core offering

CESNET operates the Czech national academic e-infrastructure, providing six interconnected ICT service pillars to public universities and the Academy of Sciences: network services (optical backbone with QKD and precise time transmission), computing services (HPC and cloud via MetaCentrum), data storage (Ceph object storage), security services (network scanning, Phishingator), multimedia collaboration (Meetings, FileSender, ownCloud), and identity management (eduID.cz / AAI). Specialized non-IP services such as quantum key distribution and nanosecond-accurate time transmission differentiate the offering.

Product overview

CESNET operates a unified e-infrastructure platform providing six core interconnected services: Network Services (backbone network, optical networks, quantum key distribution), Computing Services (HPC clusters, cloud platforms via MetaCentrum as Czech NGI), Data Storage (Ceph-based distributed object storage), Security (cybersecurity services including network scanning), Multimedia (video conferencing, streaming), and Identity (authentication via eduID.cz federation and AAI). Additional specialized services include FileSender, ownCloud, Meetings, and Phishingator. The infrastructure connects nearly 250 institutions across the Czech Republic and serves over 450,000 users.
