Polsko-francuski zespół na podium #LockedShields25! 🇵🇱🇫🇷 Zakończyła się 15. edycja #LockedShields – największych na świecie ćwiczeń NATO z zakresu obrony cyberprzestrzeni. W wydarzeniu wzięło udział 17 zespołów szybkiego reagowania, które przez kilka dni broniły infrastruktury fikcyjnego państwa Berylia przed skoordynowanym cyberatakiem sił z Crimsonii. W tym roku Polacy – pod dowództwem oficera @CyberWojska – połączyli siły z francuskimi specjalistami z @ComcyberFR i wspólnie wywalczyli wysokie 2. miejsce! Gratulacje dla całego zespołu‼️👏🏼
