In their own words
CrowdSec
CrowdSec is an open-source security stack designed to detect and block malicious IP addresses to protect infrastructure and applications. Its Security Engine analyzes logs and requests for harmful behavior, while the Remediation Component blocks IPs identified by that engine across supported platforms. CrowdSec says analysis takes place locally and logs do not leave the user's infrastructure. Its AppSec Component can provide web application firewall protection. The free Community offering includes real-time decision management, audit support, AWS CloudTrail scenarios, CAPI allow lists, and Kubernetes audit acquisition. IP Reputation data includes contextual criteria, activity timelines, autonomous system and IP range reputation, MITRE technique classification, and hourly updates. Listed integrations include Microsoft Sentinel, AWS log sources, WordPress, Cloudflare, Docker, and Kubernetes. The Community Security Engine is free. The IP Reputation API is listed at $49 a month for 5,000 queries; other listed services include blocklists and threat-intelligence options. CrowdSec lists Linux, macOS, and Windows among its platforms, with API, extension, self-hosted, and web options.
