 # Crowdsec
 > [Crowdsec](https://www.crowdsec.net/) is a crowdsourced intrusion detection and prevention system (IDS/IPS) that will detect suspicious login activity and ban IP addresses. These bans result from both a) local detection of e.g. brute-force login attempts based on the Paperless-ngx log files and b) the real-time community feed of aggressive IPs (IPs that show malicious activity within the Crowdsec user community, will be added to this list).
