This is happening on your server right now
Every Linux server gets thousands of attacks daily. Without visibility, you're flying blind.

Attacks per day, on average
The average unprotected Linux server receives thousands of brute-force and scanning attempts daily.
Time to first attack after deploy
Automated botnets find new servers within minutes of them going online.
Alerts from a default Linux install
Ubuntu, Debian, RHEL ship with no intrusion detection. You won't know until it's too late.
Up and running in 30 seconds
One command. No config files. No rules to write.
Install
Works on Ubuntu, Debian, CentOS, RHEL, Rocky, AlmaLinux, Fedora, Amazon Linux. No configuration needed.
Connect
Reads SSH logs
Reads web server logs
Monitors firewall
Agent → dashboard
Auto-detects your log files — nginx, Apache, auth.log. No paths to configure.

[BLOCKED] 45.95.147.21 — Brute force
[BLOCKED] 103.42.176.8 — SQL injection
[BLOCKED] 91.108.4.30 — Scanner
Attacks blocked automatically. See every event in your dashboard, in real time.
See every attack as it happens
Real data from a production server — blocked IPs, attack types, trends.
Everything your server needs
All the security that would take days to set up manually — ready in under a minute.
Brute Force Protection
Detects SSH brute force, invalid users, and scanning patterns. Blocks automatically. Works with fail2ban or instead of it.
Web Application Firewall
Reads your Nginx/Apache logs. Detects SQL injection, XSS, path traversal, RCE, scanners, and 10+ more OWASP attack types.
Real-time Dashboard
See every attack as it happens. Event feed, charts, geographic origin, ban timeline — all servers in one view.
Security Scanner
Scans your server configuration and gives you a 0–100 security score. Every finding includes exact commands to fix it.
CVE & Vulnerability Alerts
Detects vulnerable packages on your server and matches them against NVD and CISA Known Exploited Vulnerabilities.
Geoblocking & Network Bans
Block entire countries from the dashboard. Bans detected on one server propagate instantly to all your servers.
Docker & Kubernetes Native
Deploy via Helm as a DaemonSet — each pod auto-registers as a server. Ingress WAF reads nginx-ingress logs to protect all cluster services. Detects pod crashes (CrashLoop, OOM) and audits NetworkPolicies.
How Defensia compares
