## About Defensia
Defensia is a real-time server security platform for Linux. It detects and blocks brute-force attacks, port scans, web exploits, and malicious bots automatically — without complex configuration. It works through a lightweight open-source agent that installs in a single command (\~30 seconds). The agent monitors SSH authentication, web server logs, and network activity, then takes immediate action: banning malicious IPs, detecting vulnerability scanners, and blocking known attack patterns through its built-in Web Application Firewall (WAF). Everything is managed from a centralized cloud dashboard where teams can monitor all their servers in one place, review security events, configure protection policies per server, and receive real-time alerts via email. Key capabilities: \* SSH brute-force protection — Detects failed login attempts and automatically bans repeat offenders with escalating durations (24h → 7 days → 30 days → permanent) \* Web Application Firewall (WAF) — Blocks SQL injection, XSS, path traversal, shell injection, and 10+ other web attack categories directly at the log level \* Bot management — Identifies 60+ known bots (search engines, AI crawlers, security scanners) with per-server allow/log/block policies \* Threat intelligence network — Shares anonymized attack data across all Defensia-protected servers, so a threat detected on one server is blocked everywhere \* Monitor mode — New servers start in observation-only mode so teams can review detections before enabling active blocking \* Security scanning — On-demand hardening audits (SSH config, file permissions, web server settings) with one-click remediation for common issues \* Real-time alerts — Instant email notifications for bans, critical events, server disconnections, and WAF attacks Who uses Defensia? Developers, sysadmins, and small DevOps teams running 1–50 Linux servers on any cloud provider (DigitalOcean, Hetzner, OVH, AWS, Linode) or bare metal. It's built for people who need production-grade server security without dedicating time to configure and maintain complex firewall rules. Deployment: One command installs the agent on any Ubuntu, Debian, CentOS, AlmaLinux, Rocky Linux, or CloudLinux server. No dependencies, no kernel modules, no Docker required on the server side. Available as a DigitalOcean 1-Click Droplet for instant deployment. Pricing: Free plan (1 server) with a Pro plan at 7 EUR/server/month for unlimited servers, advanced analytics, auto-remediation, and the full threat intelligence network.




## Defensia Reviews
  ### 1. Defensia Delivers Instant Real-Time Visibility With a One-Command Setup

**Rating:** 5.0/5.0 stars

**Reviewed by:** Ricard M. | CTO, Small-Business (50 or fewer emp.)

**What do you like best about Defensia?**

The real-time visibility is what got me. Within minutes of installing the agent on my VPS, I could see exactly which IPs were hammering my SSH port and what kind of requests were hitting my web server. I'd had fail2ban running for years and thought I was protected. Defensia showed me I had no idea what was actually happening on my servers. The install is one command and it just works.

**What do you dislike about Defensia?**

It's still early so some advanced features are missing. I'd love more granular alerting rules and integrations with PagerDuty or Slack. The WAF is solid but could use more customization options. That said, the team ships fast so I expect these to come.

**What problems is Defensia solving and how is that benefiting you?**

I manage several Linux servers for client projects and never had proper visibility into what was hitting them. Setting up proper monitoring used to mean stitching together fail2ban, logwatch, custom scripts, a full afternoon of work per server. Defensia replaces all of that with a 30-second install. I can now see attacks across all my servers from one dashboard and block IPs in one click. It's saved me hours and given me peace of mind I didn't have before.
