CybSim

CybSim is a cybersecurity simulator designed for Blue Team and Red Team training. Automatically build a realistic information system based on your chosen sector—hospital, bank, SCADA industry, telecom operator, university, city hall, data center, SME, hospitality, or pharmacy—then defend it against realistic attack scenarios.

KEY FEATURES

• Automatic construction of sector-specific information systems, with real nodes and sector-specific vulnerabilities (CVEs)
• Blue Team missions based on MITRE ATT&CK, NIST SP 800, and ANSSI recommendations
• Advanced scenarios: Red Team vs. Blue Team, Nation-State APT, AWS/Azure hybrid cloud
• Progression and credit system, with a daily login reward
• Google Play Games integration to access your progress across all your devices
• Works 100% locally—no browsing data collected

WHO IS IT FOR?

CybSim is designed for students, professionals retraining in cybersecurity, SOC/CERT teams in continuing education, and anyone wishing to gain practical experience in defending an information system without risking a real production environment.

Each mission replicates recognized methodologies and frameworks (MITRE ATT&CK, NIST, ANSSI), ensuring learning is grounded in real-world defensive cybersecurity practices.
