Czech Republic — Cyber Threat Profile
The Czech Republic's 2026 landscape is governed by a new National Cyber Security Strategy (NCSS) managed by NÚKIB. The strategy emphasizes proactive defense against state-sponsored actors, specifically citing Russia and China as primary threats. Hosting the NATO Cyber Champions Summit in 2026, the nation has reinforced its role in international cyber-diplomacy. Key priorities include securing the ICT supply chain through the "Toolbox" initiative and ensuring NIS2 compliance across critical sectors. Domestic efforts are heavily focused on 5G security, autonomous vehicle protection, and increasing the cybersecurity workforce to maintain its reputation as a highly resilient EU member.- National CERT/CSIRT: CSIRT.CZ
