CrowdSec Managed Rules - block Crowd-sourced malicious IP on AWS WAF

Product Overview

Most traditional threat intelligence relies on honeypots, which only catch cybercriminals who are blindly scanning the internet. The CrowdSec Intelligence Blocklist (CIB) takes a fundamentally different and more effective approach: it is fueled by a global network effect of over 400,000 real, highly diversified servers protecting actual businesses. Because we protect real workloads, we catch targeted, complex, and costly attacks that honeypots simply miss. Our worldwide network processes around 40-50 million aggressions daily, distilling them into a highly curated, real-time blocklist of the most aggressive cybercriminal IP addresses. By leveraging this "digital herd immunity," your AWS infrastructure benefits from crowdsourced protection that is consistently 1 to 10 weeks ahead of traditional intelligence providers. In fact, 36% of the IP addresses on our high-threat list were exclusive to CrowdSec when first published. Leverage our unique network effect to your benefit

• Real Workloads vs. Honeypots: Cybercriminals adapt to honeypots, but they cannot evade the defenses of real, production environments. CrowdSec captures data from real customers actively targeted by attackers, yielding actionable and high-fidelity intelligence.
• Zero False Positives: We employ a rigorous Consensus Algorithm that analyzes sightings across multiple autonomous systems. IPs are only blocked if reported by enough trusted network members over time, ensuring zero false positives and immunity to adversarial poisoning.
• Real-Time Actionability: IP addresses are dynamically added and removed by the minute based on their ongoing aggressivity, ensuring your defenses are never stale.
• Massive Cost & Resource Optimization: Blocking threats at Layer 3 with CIB prevents attacks from taxing your application resources. Customers typically see a 14% reduction in cloud computing bills and up to a 60% reduction in SIEM log ingestion costs. Furthermore, eliminating this background noise reduces alert fatigue (dropping alerts by 82%) and saves Security Operations Centers (SOCs) the equivalent of 2 to 3 full-time employees' workloads.

Key Capabilities & Protection

The CrowdSec Intelligence Blocklist seamlessly integrates into your AWS edge filtering (such as AWS WAF or Network Firewall) to provide immediate, plug-and-play protection. It actively shields your infrastructure from:

• Vulnerability Exploitation: Proactively blocks CVE hunters attempting to exploit known and emerging vulnerabilities.
• Credential Attacks: Stops brute-force attempts, credential stuffing, and injection attacks.
• Web & API Abuse: Mitigates Layer 7 (application) DDoS attacks, cross-site scripting (XSS), and SQL injection attacks.
• Automated Fraud: Thwarts scalping bots, credit card stuffing, and massive network scanning.

By implementing the CrowdSec Intelligence Blocklist, 92% of attacks can be preemptively blocked at the edge without requiring any further application-level treatment, drastically improving your security posture with nearly zero installation time.
