  • InfluxDB

    Power Real-Time Data Analytics at Scale. Get real-time insights from all types of time series data with InfluxDB. Ingest, query, and analyze billions of data points in real-time with unbounded cardinality.

  • crowdsec

    CrowdSec - the open-source and participative security solution offering crowdsourced protection against malicious IPs and access to the most advanced real-world CTI.

    I would, however, suggest CrowdSec over Fail2Ban. It's free, open source crowdsourced threat intelligence. Think of it as a modern version of f2b. Most notably is the fact that it's distributed, can run from one central installation and shares data of attacks among users (hence the crowdsourced part). Furthermore it's capable of taking much more advanced decisions and detect much more advanced attacks ranging from slow bf, L7 DDoS, Credit card stuffing, scalping, data exfiltration and much more.
