What is Defensia?

Defensia is a lightweight security agent for Linux servers that detects and blocks real attacks in real time — without complex configuration. Install with a single command and within minutes you'll see exactly what's hitting your server: SSH brute force attempts, web application attacks (SQLi, XSS, RCE, path traversal and 12 more OWASP types), port scans, and more.

Key features:

  • Real-time dashboard showing live attack feed and blocked IPs
  • Web Application Firewall (WAF) with 15 OWASP attack type detection
  • Automatic IP blocking via iptables
  • GeoIP blocking by country
  • Network-level ban propagation across all your servers
  • Security scanner for misconfigurations and vulnerable software
  • Auto-update with rollback
  • Configurable per server from the dashboard

Unlike fail2ban, Defensia gives you full visibility — not just blocking, but a real-time view of what's happening on your server right now. Unlike CrowdSec, it's a single agent with a hosted dashboard, no community hub required. Works on Ubuntu, Debian, CentOS, RHEL, Amazon Linux.
