CrowdSec vs pfSense

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.

pfSense is a free, open-source FreeBSD distribution for firewall and router functions, managed through a web interface. Its source code is distributed under the Apache 2.0 license, and a package system lets users add functionality. Documented network features include firewalling, routing, VLANs, multiple WAN connections, high availability, traffic shaping, and captive portal. VPN options include IPsec, OpenVPN, and WireGuard; OpenVPN documentation lists authentication through local users, LDAP, or RADIUS servers. Deployment options include hardware, virtual machines, and public cloud. The software is available in the AWS and Azure marketplaces, including their US GovCloud regions. Netgate publishes security advisories, accepts vulnerability reports through its Security Team, and sells global support for self-installed software and virtual deployments. The Community Edition is a free download; listed Plus support plans offer either a limited number of tickets or unlimited tickets. One installation constraint: the USB memstick installer overwrites the entire hard drive and does not support dual booting with another OS.
