CrowdSec
Summary
CrowdSec is an open-source security stack designed to detect and block malicious IP addresses to help safeguard infrastructure and applications. Its Security Engine analyzes logs and requests for harmful behavior, while the Remediation Component blocks IPs identified by the engine across supported platforms. CrowdSec says analysis happens locally and logs remain within 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. The IP Reputation service provides contextual criteria, activity timelines, autonomous system and IP range reputation, MITRE technique classification, and hourly updated data. 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 49.00 USD per month for 5,000 queries; other listed services include blocklists and threat-intelligence options. CrowdSec lists industries including hosting, education, ecommerce, finance, government, media, and healthcare.
Who it is for
CrowdSec may suit infrastructure and application security teams, including organizations in hosting, education, finance, healthcare, and other listed industries. Its locally performed log analysis may be relevant to teams that want logs to stay within their infrastructure.
