+* [Nemea modules](https://github.com/CESNET/Nemea-Modules): Base modules of the system for export&storage of flow data, replay of stored flow data, filtering, merging, and others. It also contains a basic flow exporter capable of L7 information. 
+* [Nemea detectors](https://github.com/CESNET/Nemea-Detectors): Detection modules that can detect and report various types of malicious traffic such as DoS, DDoS, scanning, bruteforce attacks.
+* [Nemea Supervisor](https://github.com/CESNET/Nemea-Supervisor): Central management and monitoring module of the Nemea system. It takes care of running modules according to configuration.
