by crowdsecurity
CrowdSec is an open-source, community-driven security solution that detects and blocks malicious IPs using crowdsourced threat intelligence and real-time remediation.
CrowdSec - the open-source and participative security solution offering crowdsourced protection against malicious IPs and access to the most advanced real-world CTI.
Primary Use Case
CrowdSec is primarily used by system administrators and security teams to detect intrusion attempts and malicious behaviors by analyzing logs and HTTP requests across various platforms. It enables organizations to proactively block harmful IPs using a shared community blocklist and automate security responses to protect infrastructure at multiple levels.
- All-in-one IDS/IPS and WAF security engine analyzing logs and HTTP requests
- Crowdsourced Community Blocklist of malicious IP addresses updated in real-time
- Active remediation through pluggable Remediation Components (bouncers)
- Extensible detection rules available under MIT license via the CrowdSec Hub
- Multi-platform support including Linux, Windows, Docker, Kubernetes, and OpnSense
- Centralized monitoring and automation via CrowdSec Console
- Pre-built scenarios for common attacks like brute force, port scanning, and web scanning
- Participative threat sharing to enhance collective protection
