Wordfence is the most popular WordPress security plugin with 5 million+ active installations — and it's great at what it does. But it only sees WordPress. Your SSH, your databases, your email server, your other apps? Invisible. Defensia protects everything on the server with one agent.
$ Log in to WordPress admin
$ Install Wordfence plugin
$ Enter Premium license key ($149/year)
# Configure firewall learning mode...
# Wait 1 week for firewall optimization...
# Repeat for every WordPress site...
# 10 sites = ~$1,182-1,490/year
Per-site setup. PHP overhead on every request.
$ curl -fsSL https://defensia.cloud/install.sh | sudo bash
✓ All WordPress sites protected
✓ SSH protection active
✓ Web firewall active (nginx + Apache)
✓ Malware scanner ready (64K+ signatures)
✓ CVE scanner running
✓ Dashboard connected
30 seconds. Every site on the server. One price.
Wordfence is excellent WordPress security. But once you manage multiple sites or care about the full server, you hit these walls:
Wordfence Premium is $149/year per site. Running 10 WordPress sites? That's $1,490/year just for the WAF and malware scanner. Defensia is EUR 9/month for the entire server — every site included, regardless of how many you host.
Wordfence's firewall runs via PHP auto_prepend_file on every single HTTP request. Benchmarks show it adds ~0.2 seconds per page load and can double PHP memory usage. Some hosting providers have banned it for excessive resource consumption. Defensia's Go agent runs outside of PHP entirely — zero impact on your WordPress performance.
Wordfence can't see SSH. If someone brute-forces your SSH login, Wordfence has no idea. Defensia detects 15 SSH attack patterns and blocks attackers at the firewall level within seconds.
Your server runs more than WordPress — databases, email, cron jobs, other applications. Wordfence only sees the WordPress directory. Defensia monitors the entire server: every log, every port, every service.
Managing 5 servers means logging into 5 separate WordPress admins to check Wordfence. Defensia gives you one real-time dashboard across all servers with live attack feeds, charts, and alerts.
Wordfence is a PHP plugin — it has no concept of containers. Defensia natively supports Docker detection, container monitoring, and Kubernetes DaemonSet deployment via Helm chart.

Wordfence sees WordPress. Defensia sees the entire server — and everything running on it.
SSH brute force detection (15 patterns), email server protection, database port monitoring, and firewall management. Everything Wordfence can't see because it lives inside WordPress.
64,000+ hash signatures, 684 dynamic patterns, web shell detection, cryptominer detection, rootkit checks, WordPress database scanning for malicious posts and rogue admins, quarantine, and security posture scoring (0-100).
See every attack, every ban, every CVE across all your servers in real time. Live charts, event feeds, geographic distribution, and alerts to Slack, email, Discord, or webhooks. No more checking 10 separate WP admins.
We believe in being honest. Wordfence is excellent software. Here are cases where it might suit you better:
Yes, and many users do. They solve different problems at different layers:
Wordfence Free + Defensia Pro gives you deep WordPress protection AND full server security for EUR 9/month — far less than Wordfence Premium alone ($149/year per site).
Yes, and it's a great combination. Wordfence Free handles WordPress-specific concerns (login 2FA, plugin vulnerability alerts, core file integrity) while Defensia handles everything else: SSH protection, server-level WAF for all sites, malware scanning with 64K+ signatures, CVE scanning, geoblocking, and multi-server monitoring. They operate at different layers and don't conflict.
Yes. Defensia's malware scanner checks all files on the server, including WordPress directories. It uses 64,000+ hash signatures and 684 dynamic detection patterns to find web shells, backdoors, and cryptominers. It also scans the WordPress database for malicious content in posts, suspicious options, and rogue admin accounts. What it doesn't do is WordPress core file integrity diffing against the official repository — that's where Wordfence excels. Note: Wordfence also offers a separate CLI tool (GPLv3, Python-based) that can scan arbitrary server paths, though it's a different product from the WP plugin.
Wordfence Premium: $149/year per site (volume discounts bring it to ~$112/site for 15+ sites). Care: $590/year. Response: $1,250/year. 10 sites at Premium = $1,182-1,490/year. Defensia Pro: €9/month per server (€7 billed annually). One server with 10 or 50 WordPress sites = €9/month total. The more sites you run per server, the bigger the savings.
Wordfence's WAF runs as a PHP auto_prepend_file on every HTTP request. Independent benchmarks (PluginTests.com, 2025) show it adds ~0.224 seconds average per page load. It requires approximately 10x more CPU than an average plugin and can double peak PHP memory usage. Wordfence recommends minimum 128MB PHP memory. Defensia's Go agent runs as a separate system service at the OS level with zero impact on PHP performance.
Wordfence Free is still a good option for WordPress-specific security. But even with one site, your server has SSH, possibly a database port, maybe email — none of which Wordfence protects. Defensia Free covers 1 server with SSH protection and the real-time dashboard at no cost. Running Wordfence Free + Defensia Free gives you strong protection across both layers.
Yes. The agent is MIT licensed and available on GitHub. Written in Go, it uses under 30MB of memory. The dashboard is a commercial SaaS with a free tier for one server.
