CrowdSec is powerful but complex. Defensia gives you the same protection with zero configuration.
$ curl -s https://packagecloud.io/install/.../script.deb.sh | bash
$ apt install crowdsec
$ nano /etc/crowdsec/acquis.yaml
# Configure YAML parsers for each log source...
# Install bouncers (firewall-bouncer, nginx-bouncer)...
# Register on console.crowdsec.net for dashboard...
# Browse community hub for scenarios...
$ systemctl restart crowdsec
~10-20 minutes. YAML configs + bouncer setup.
$ curl -fsSL https://defensia.cloud/install.sh | sudo bash
✓ SSH protection active
✓ Web firewall active (nginx + apache)
✓ Dashboard connected
✓ CVE scanner running
✓ Real-time alerts ready
28 seconds. Zero config files.
CrowdSec is a solid project. But after running it for a while, many sysadmins hit the same friction points:
CrowdSec requires YAML parsers for each log source, scenarios for each attack type, and bouncers for each enforcement point. That's three layers of config to manage per service.
The free CrowdSec tier is CLI-only. To get a web dashboard, you need the paid CrowdSec Console. Defensia includes a full real-time dashboard on every plan, including free.
CrowdSec detects threats but doesn't block them by default. You need to install and configure separate bouncers (firewall, nginx, etc.). Defensia blocks automatically out of the box.
Need to protect a new service? You have to find (or write) a parser and scenario from the community hub. Defensia auto-detects services and protects them without extra downloads.
Side by side, feature by feature.

| WAF | Built-in (15+ OWASP types) | Requires bouncer setup |
| Bot management | 70+ fingerprints, allow/log/block | Basic |
| Multi-server dashboard | Included | Paid (console) |
| CVE scanning | Yes (NVD + EPSS + CISA KEV) | ✗ |
| Mail server protection | Built-in (Postfix/Dovecot/Roundcube) | Community scenario |
| Database protection | Built-in (MySQL/PostgreSQL/MongoDB) | Community scenario |
| Community hub required | ✗ | ✓ |
| Docker / K8s native | Helm chart + Docker labels | Partial |
| Price | Free (1 server) + €9/server/mo | Free + $900–3900/mo blocklists |
| Open source agent | Yes (Go, MIT) | Yes (Go) |
These features work out of the box — no YAML, no bouncers, no hub downloads.
Detects SQL injection, XSS, RCE, path traversal, and 15+ OWASP attack types from your nginx/Apache logs. No bouncer install, no YAML scenarios. It just works.
Scans your installed packages against the NVD database with EPSS scoring and CISA KEV alerts. Know about critical vulnerabilities before attackers exploit them.
70+ bot fingerprints with per-bot allow, log, or block policies. Distinguish good bots (Googlebot, monitoring) from bad bots (scrapers, scanners) automatically.
We believe in being honest. CrowdSec is a strong project. Here are cases where it might suit you better:
Yes. Defensia and CrowdSec can run on the same server simultaneously. They both write iptables rules independently. Many users run both during a transition period, then remove CrowdSec once they see Defensia covers everything they need with less complexity.
No. The agent auto-detects your SSH logs, nginx/Apache logs, mail server logs, and database logs. Everything is configured from the web dashboard. There are zero config files on the server.
Not currently. Defensia focuses on real-time, per-server detection and blocking. We detect attacks as they happen using log analysis and WAF rules rather than relying on shared blocklists. We plan to add optional threat intelligence feeds in the future.
Defensia: free plan (1 server, full dashboard, SSH protection) + Pro at €9/server/month for WAF, CVE scanning, bot management, geoblocking, and alerts. CrowdSec: free tier is CLI-only, the Console starts at paid plans, and premium blocklists range from $900–3,900/month.
Yes. The agent that runs on your server is MIT licensed and available on GitHub. It's written in Go, just like CrowdSec. The dashboard is a commercial SaaS with a free tier for one server.
