The strongest All-In-One Security alternative for most sites is Wordfence Security, whose endpoint firewall and malware scanner draw on one of the largest threat databases in WordPress. For free server-level monitoring and hardening, Sucuri Security is an excellent pick, and Kadence Security offers the friendliest all-round hardening. We ranked these from our index of 55,000+ WordPress plugins.

Why people switch from All-In-One Security (AIOS)

• People wanting a stronger, actively updated firewall and malware scanner move to Wordfence Security or NinjaFirewall.
• Sites needing file-integrity monitoring and security auditing switch to Sucuri Security.
• Users who find AIOS cluttered prefer the cleaner hardening flow of Kadence Security.
• Advanced users wanting a firewall that runs before WordPress loads choose NinjaFirewall or WP Cerber Security.

Wordfence Security – Firewall and malware scanning

Wordfence Security is the most widely used WordPress security plugin, combining an application firewall, a deep malware scanner, and login security backed by a large threat-intelligence feed. Against All-In-One Security (AIOS), its scanning and firewall rules are more comprehensive and more actively maintained. The drawback is resource use: its scans and firewall can be demanding on shared hosting, and the newest firewall rules are delayed on the free tier for thirty days.

Choose Wordfence Security if you want the most comprehensive malware scanning and firewall available.

Sucuri Security – Auditing and integrity monitoring

Sucuri Security from the Sucuri team offers file-integrity monitoring, security activity auditing, and remote malware scanning, with an optional cloud firewall. Against All-In-One Security (AIOS), its logging and integrity checks are more thorough for spotting when something has changed. The honest limitation is that the truly protective firewall is Sucuri’s paid cloud WAF, so the free plugin is strongest at monitoring and hardening rather than actively blocking attacks.

Choose Sucuri Security if you want strong auditing and file-integrity monitoring, with a cloud firewall option.

Kadence Security – Approachable hardening

Kadence Security, now published as Kadence Security, is a broad hardening suite with brute-force protection, two-factor, and sensible defaults presented in a guided way. Against All-In-One Security (AIOS), its interface is cleaner and easier to work through for non-experts. The drawback is that its real-time malware scanning and site-monitoring depend on paid plans and connected services, so the free version leans more on hardening than on active threat detection.

Choose Kadence Security if you want approachable, well-guided hardening without a steep learning curve.

NinjaFirewall – Server-level firewall

NinjaFirewall is a true web application firewall that can run before WordPress and even before PHP fully loads, filtering requests very early. Against All-In-One Security (AIOS), its filtering happens at a lower level, which stops many attacks before they reach WordPress. The trade-off is complexity: proper setup, especially full WAF mode, is more technical and less point-and-click than AIOS, so it suits administrators comfortable with server configuration.

Choose NinjaFirewall if you want a powerful firewall that filters requests before WordPress loads.

wp-cerber – Login and traffic control

WP Cerber Security is a security plugin known for granular login protection, traffic inspection, and anti-spam controls with detailed activity logging. Against All-In-One Security (AIOS), it gives finer control over who can reach login and admin areas. The honest drawback is availability and cost: WP Cerber left the WordPress.org repository and is now distributed through its own site with much of its strength in the paid edition, so it is less convenient to install and trial.

Choose wp-cerber if you want granular login and traffic controls and do not mind installing from its own site.

When to stay on All-In-One Security (AIOS)

Stay on All-In-One Security (AIOS) if its free bundle of firewall rules, login protection, and hardening already covers your needs and you like managing it from one grading dashboard. It packs a lot into a free plugin, and for many small sites that is enough. Switching mainly pays off when you want stronger malware scanning, deeper auditing, or a firewall that runs closer to the server.

How we ranked these

Every plugin here is scored by the WPS Score, a single 0 to 10 rating built from 21 signals covering maintenance, support responsiveness, compatibility, performance, and ratings quality across our index of 55,000+ plugins.

Frequently asked questions

Is Wordfence better than All-In-One Security?

Wordfence generally offers stronger malware scanning and a more actively maintained firewall, backed by a large threat-intelligence feed. All-In-One Security bundles solid free hardening and login protection but has a lighter scanner. Wordfence can be heavier on shared hosting, so the right choice depends on how much active threat detection you need.

Can I run two security plugins at the same time?

It is not recommended. Running All-In-One Security alongside Wordfence or another firewall can cause conflicting rules, duplicated login protection, and performance problems. Choose one primary security plugin, and if you need a specialised tool such as a login limiter, make sure its features do not overlap.

What is the best free security plugin for WordPress?

Wordfence is the most popular free choice for its scanner and firewall, while Sucuri Security is excellent for free auditing and file-integrity monitoring. Kadence Security offers the most approachable hardening. The best pick depends on whether you prioritise active scanning, monitoring, or ease of use.

The verdict

The best all-round All-In-One Security alternative is Wordfence Security for its scanning and firewall depth. For monitoring and auditing choose Sucuri Security, and for approachable hardening choose Kadence Security. If AIOS already covers your site well from its single dashboard, staying on All-In-One Security (AIOS) remains a reasonable choice.
