DefendWP Firewall

46 Quality Score

Active Installs

16/30

3,000 active installs puts it well outside the mainstream, signalling a niche or very early product rather than an established choice.

Update Freshness

12/25

Updated within the last few months and tested against WordPress 6.8.5, the maintenance signal is reasonable for a small project.

User Rating

0/15

Zero ratings out of zero submitted means there is no validated user feedback to draw on, which is a meaningful trust gap.

Support Health

8/15

No public support threads have been opened or resolved, so the developer's responsiveness is unproven.

WP Compatibility

11/15

Requires PHP 8.1 and WordPress 6.2 or higher, which is current and aligns well with modern hosting environments.

What It Does

DefendWP Firewall applies rule-based protections against known vulnerabilities as they are disclosed by security researchers and companies. It sits in front of your WordPress install to block exploit attempts targeting newly published CVEs and known attack patterns. In practice it is a lightweight, signature-driven WAF layer that aims to shield your site before you have time to patch.

Who It's For

This plugin suits small business owners, agencies managing multiple client sites, and WooCommerce operators who want an extra layer of automated virtual patching between vulnerability disclosure and plugin update cycles. It is also a fit for hosts and multi-site administrators running lean stacks where every request to a heavier security suite feels excessive.

Who Should Skip It

If you already run Wordfence, Really Simple Security Pro, or a host-level WAF such as Cloudflare or Sucuri, you are paying the performance cost of running a second firewall for marginal added coverage. Enterprise sites with dedicated security teams and SOC integration should also skip this in favour of a properly managed WAF and SIEM stack.

The Bottom Line

DefendWP Firewall has a focused concept and current compatibility, but with only 3,000 installs, no ratings, and no resolved support threads, the trust signals are simply not there yet. The overall quality score of 49.6/100 places it firmly below every alternative listed, and most site owners will be better served by Wordfence or Really Simple Security. Treat it as a promising early-stage tool, not a production-ready firewall.

Pick this when you want a widely trusted, well-supported suite that covers SSL, login hardening, and a managed firewall in one package.

Wordfence Security – Firewall, Malware Scan, and Login Security 97/100

Pick this when you want the most battle-tested WordPress firewall with a large rule feed, malware scanner, and a real-time threat intelligence network.

LiteSpeed Cache 95/100

Pick this if your host runs LiteSpeed and you want server-level WAF and brute-force protection integrated directly with page caching.

Jetpack – WP Security, Backup, Speed, & Growth 94/100

Pick this when you want security, backups, and performance bundled into one Automattic-backed plugin with a long support history.

Redis Object Cache 92/100

Pick this when your priority is reducing server load at the application layer rather than blocking attacks, complementing a separate WAF.
