The concept
StealthCup is a CTF-like blue team and red team training platform. Professional red teams attack a near-real enterprise and industrial (IT and OT) network, fully monitored by real detection and monitoring tools. Stealth is what counts: every alert you trigger costs points.
-
Get in
Your team attacks a live IT/OT enterprise environment, just like a real engagement.
-
Stay invisible
The network is watched by real detection tools. Every alert you trigger costs you points.
-
Score
Reach your objectives without being seen. The best team goes the furthest, the quietest.
