CrowdSec

CrowdSec is a collaborative, free and open source security automation platform relying on both IP behavior analysis and IP reputation. CrowdSec identifies threats and shares IP addresses behind malevolent behaviors across its community, to allow everyone to block them preventively. Used in 90 countries across 6 continents, the solution builds a real-time IP reputation database that keeps growing every day and benefits all community members who have each other's backs while forming a global defense shield.How do you position yourself against your competitors?Designed for modern environments, like public clouds and containers as well as bare-metal or virtualized architectures in enterprises, CrowdSec’s software provides a strong first line of defense of unprecedented efficiency and versatility. The different types of remediation offered range from simple access prohibition to two-factor authentication, CAPTCHAs, rights limitation, and transmission of information to a SIEM or to SecOps desks, for example.CrowdSec can block port scans, web scans, password attacks, identity theft attempts, as well as application denial of service, bots, credit card stuffing, or fraud, among many other classes of attacks (over 200 malicious behaviors). By not exporting logs and collecting only the minimum amount of data (timestamp, attacking IP, and recorded behavior) CrowdSec complies with the European GDPR and, more generally, respects data privacy.
