CrowdSec

CrowdSec 1.7.4 on Ubuntu 24.04 LTS with Free Maintenance Support by bCloud

CrowdSec on Ubuntu 24.04 LTS, with maintenance support from bCloud, is a repackaged open-source offering available through the AWS Cloud Marketplace. CrowdSec is a community-powered cybersecurity solution that works as a modern Intrusion Prevention System (IPS). It analyses system logs and HTTP activity in real time to detect malicious behaviour and apply protections.

CrowdSec focuses on behaviour-based detection rather than static signatures. It detects attack patterns such as brute-force attempts, credential stuffing, port scanning, and web scraping. It can block malicious IPs using firewall rules, proxies, or WAF integrations.

In addition to the IPS deployment, AWS Marketplace may provide access to the CrowdSec CTI API, which delivers threat intelligence feeds (IP reputation lists and enrichment data) via programmatic endpoints.

Core Technical Capabilities of CrowdSec

Behavior-Based Detection

CrowdSec detects malicious activity based on behaviour scenarios, including:

• brute-force login attempts
• scraping and bot activity
• scanning patterns and probing behaviour

Real-Time Monitoring of Logs and HTTP Requests

CrowdSec analyses:

• service/application logs
• system logs
• web server access logs (HTTP behaviours)

Automated Remediation

CrowdSec can trigger defensive actions such as:

• blocking abusive IPs using firewall rules
• integration with reverse proxies/WAF tools
• reduced manual intervention during attacks

Crowdsourced Threat Intelligence (CTI)

• anonymised signals contribute to the shared dataset
• threat feeds stay continuously updated
• protection improves based on community intelligence

Scalability and Performance Control

• large traffic volumes
• continuous log ingestion
• automated threat response workflows

AWS Marketplace Advantages
