Wordfence Alternatives: 7 WordPress Security Plugins Compared (2026)

Wordfence is the most installed WordPress security plugin, with over 5 million active sites, and its free version is genuinely useful: an endpoint firewall, a malware scanner, login security with two-factor authentication and passkeys, and live traffic. So why do so many people look for Wordfence alternatives? The usual reasons are server load from scans on cheap hosting, the free version’s firewall rules and malware signatures arriving 30 days after Premium customers get them, the yearly cost of Premium across several sites, or simply wanting a different approach, such as a cloud firewall or vulnerability patching. This guide compares the best Wordfence alternatives in 2026, what each does differently and who it suits. One of them is ours (the 007AJ Security Scanner & Firewall Suite), and we say plainly where it is and isn’t the right choice.

First, decide what you are replacing

“Security plugin” covers several different jobs, and no tool does all of them equally well:

• Firewall (WAF): blocks malicious requests. An endpoint firewall runs on your server inside WordPress or PHP. A cloud firewall (Sucuri, Cloudflare) filters traffic before it reaches your server.
• Malware or integrity scanner: finds infected or modified files after the fact.
• Login security: lockouts, rate limits, two-factor authentication, passkeys.
• Vulnerability monitoring and virtual patching: warns you (or blocks the exploit) when a plugin you run has a known hole.
• Hardening and activity log: disabling the file editor, logging who changed what.

If you are unsure how the first two differ, read our explainer on WordPress firewall vs malware scanner first.

Quick comparison

1. Sucuri: move the firewall off your server

Sucuri’s free WordPress plugin offers security activity auditing, file integrity monitoring, remote malware scanning, blocklist monitoring and hardening. Its main strength, though, is the paid Sucuri platform: a cloud firewall and CDN that filters attacks (including DDoS) before they reach your host, plus malware cleanup services.

Choose it if your server struggles under bot traffic or you want professional cleanup included. Watch out for DNS changes to route traffic through Sucuri, and the subscription cost.

2. MalCare: scanning without the server load

MalCare runs its malware scanning on its own servers, so scans do not slow your site, which is the most common complaint about running Wordfence scans on shared hosting. Paid plans add one-click malware removal, a firewall, country blocking and a management dashboard for multiple sites.

Choose it if performance during scans matters and you want one-click cleanup. Watch out for the free version, which mainly detects; cleanup and firewall features are paid.

3. Patchstack: fix vulnerabilities before they are exploited

Most WordPress hacks come through a known vulnerability in a plugin or theme. Patchstack focuses on exactly that. The free version gives up to 48-hour early warning of new vulnerabilities in your plugins, themes and core, and can auto-update vulnerable software. The paid version adds targeted virtual patches (vPatches) that block a specific exploit on your site until the vendor ships a fix, plus 2FA, hardening and an IP blocklist.

Choose it if you manage several sites with many plugins. Watch out for its narrow focus: it does not replace a malware scanner or full firewall.

4. Kadence Security (formerly iThemes Security, then Solid Security)

This plugin has changed names more than once, so you may know it as iThemes Security or Solid Security. It focuses on login protection and hardening: brute force protection backed by a large network of sites, two-factor authentication (passwordless login in Pro), and security templates by site type that apply sensible settings in minutes. The Pro version includes Patchstack-powered vulnerability protection.

Choose it if you want guided, beginner-friendly setup. Watch out for malware scanning, which is lighter than Wordfence’s.

5. All-In-One Security (AIOS)

From the team behind UpdraftPlus, AIOS is a strong free alternative with over 1 million installs. It includes login lockouts and 2FA, file change detection, a firewall using PHP, .htaccess and 6G rules, fake Googlebot blocking, comment spam prevention and an audit log. Features are graded basic, intermediate and advanced, and a security score rises as you turn them on.

Choose it if you want a free, well-explained all-in-one plugin. Watch out for .htaccess rules on Nginx hosting, where they do not apply.

6. NinjaFirewall: a WAF in front of WordPress

NinjaFirewall installs like a plugin but runs as a stand-alone PHP firewall that inspects requests before WordPress or any plugin loads. That lets it filter requests to every PHP script in your installation and absorb large brute-force attacks very cheaply. It normalises encoded requests to catch evasion tricks.

Choose it if you are comfortable with server settings and want a powerful, lightweight firewall. Watch out for its requirements: Unix-like hosting only (not Windows), and a more technical setup.

7. 007AJ Security Scanner & Firewall Suite

We built the 007AJ Security Scanner & Firewall Suite for owners who want solid on-server protection with no cloud dependency and no yearly renewal. Everything runs on your server, it sends nothing to us, and every protection stays off until you switch it on, so you add protections one at a time and know exactly what changed.

• Login lockout and rate limit covering the login form, XML-RPC and application passwords, with optional email alerts.
• Request firewall with switchable categories: SQL injection, XSS, path traversal and file inclusion, code injection, sensitive file probes (.env, .git, backup archives, web shell names) and attack-tool user agents.
• IP allow and block lists (IPv4, IPv6 and CIDR), per-IP rate limits and temporary blocks for 404 floods.
• Integrity scan against official WordPress.org checksums for core and WordPress.org plugins, with repair and a quarantine undo, plus scheduled scans with an email digest and file change monitoring.
• Live traffic, an activity log and hardening switches (file editor, username discovery, version tag, application passwords).

Choose it if you want a privacy-friendly, on-server firewall and integrity scanner for a one-time price. Be aware that it has no cloud malware-signature database (it compares files with WordPress.org checksums instead, so themes and premium plugins are listed as not checked), no country blocking and no two-factor login. Pair it with a 2FA plugin and good backups.

Can you combine security plugins?

Avoid running two plugins that both act as firewalls or both do login lockouts, because they can conflict or lock you out. Sensible combinations are:

• A cloud firewall (Sucuri or Cloudflare) plus one on-server security plugin.
• Patchstack for vulnerability alerts plus one firewall and scanner plugin.
• Any security plugin plus off-site backups. Security reduces the chance of a hack, and backups decide how bad one is. See our comparison of the best WordPress backup plugins for 2026.

If you use a CDN or proxy such as Cloudflare, make sure your security plugin sees the real visitor IP, not the proxy’s. Otherwise lockouts can block the proxy and take your whole site offline for everyone.

Is it worth leaving Wordfence?

If Wordfence runs smoothly on your host and you are happy with it, the free version is still a reasonable choice. Switch if scans slow your site down, you want real-time protection without a yearly licence per site, you need a cloud firewall in front of a struggling server, or you want vulnerability patching as your first line of defence. Whatever you choose, keep WordPress, plugins and themes updated, remove plugins you do not use and turn on two-factor authentication for every administrator. Those three habits prevent more hacks than any plugin.

Frequently asked questions

Is Wordfence free good enough?

For many small sites, yes. The main limitation is that firewall rules and malware signatures reach free users 30 days after Premium users, which leaves a window for brand-new attacks.

What is the best free Wordfence alternative?

All-In-One Security (AIOS) is the most complete free all-rounder. Patchstack’s free plan is a useful extra for vulnerability alerts alongside it.

Which security plugin is lightest on server resources?

Cloud-based options (MalCare scanning, Sucuri’s firewall) move the heavy work off your server. Among on-server options, opt-in plugins that only run what you switch on keep overhead low.

How do I switch from Wordfence safely?

Take a full backup, install and configure the new plugin, then deactivate Wordfence. Its firewall may load early through a .user.ini or auto_prepend_file setting, so use its own option to remove the optimized firewall before you delete it.

Do I still need a security plugin if my host has a firewall?

Host firewalls block a lot, but they do not usually give you login lockouts, file integrity checks or an activity log for your WordPress site. Most sites benefit from one WordPress-level plugin as well.
