Deploy, configure, and operate CrowdSec Security Engine, cscli, remediation components, acquisition pipelines, and AppSec WAF. Use for Linux or Docker installation, detection-to-blocking design, incident review, and safe changes. Do not use for generic firewall, Kubernetes, or reverse-proxy design; route those to the named platform skill and use this skill for CrowdSec integration.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# CrowdSec CrowdSec detects hostile behavior from logs and HTTP requests, then exposes alerts and decisions through LAPI. The engine alone does not block traffic: install and verify at least one remediation component (bouncer) before claiming protection. ## Safety Gate Before any mutation, confirm the target host/container, scope, backup or rollback, and maintenance window. Prefer read-only inspection and simulation first. Never manually delete decisions, collections, or data without recording the reason and an undo path. Save bouncer keys when created; they are shown once. Use `simulation: true` while tuning scenarios so detections are observed without enforcement, then verify allowlists before live blocking. ## Choose a Deployment For Debian/Ubuntu, add the CrowdSec repository, install `crowdsec`, then install a remediation package such as `crowdsec-firewall-bouncer-iptables` or `-nftables`. For Docker Compose, expose LAPI (`127.0.0.1:8080`), metrics (`127.0.0.1:6060`), and AppSec (`127.0.0.1:7422`) only to required networks, mount `/etc/crowdsec`, `/var/lib/crowdsec/data`, and logs read-only, and pin a …

How to install
mdr add magnus919/agent-skills/crowdsec@sha256:4722c930da55bfd8The line at the top of this page pins the label v0.0.3, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
