Defensia is an open-source agent for Linux servers paired with a real-time SaaS dashboard. Install in one command and get SSH brute force protection, a Web Application Firewall (SQL injection, XSS, path traversal, RCE detection), CVE vulnerability scanning, geoblocking across 200+ countries, and centralized multi-server management, all with zero configuration. Unlike Fail2ban, Defensia requires no config files. It auto-detects nginx, Apache, and SSH logs and starts protecting your server immediately. The dashboard shows live attack feeds, ban history, security scores, hardening checks, and compliance reports. Alerts via Slack, email, and webhooks. The agent is MIT licensed and available on GitHub. Free plan covers 1 server with SSH protection and the full dashboard. Pro plan adds unlimited servers, WAF, CVE scanning, geoblocking, and team management at โฌ9/month per server (โฌ7/month billed annually).

Defensia.cloud's answer:
Defensia is the only Linux security tool that combines an open-source agent with a real-time SaaS dashboard, no config files, no regex filters, no manual setup. You get SSH protection, a full WAF, CVE scanning, and multi-server management from a single install command. Everything Fail2ban does, plus a dashboard that shows you what's actually happening on your servers.
Defensia.cloud's answer:
Because it works in 30 seconds and requires zero configuration. Fail2ban needs manual regex filters for every service. CrowdSec requires YAML config and a community hub. Defensia auto-detects your stack and starts protecting immediately. The real-time dashboard, CVE scanner, compliance reports are included and multi server dashboard, not sold as separate products.
