Every web platform has security vulnerabilities. WordPress, however, is by far the most popular content management system (CMS) around the world, making it an especially attractive target for hackers. These cybercriminals spend a ton of time and energy identifying WordPress vulnerabilities.
So how can you protect your site? See which best WordPress security plugin we’ve uncovered in our best WordPress security plugin reviews. We’ve included several options for your specific needs, and while many of these solutions offer “plugins” for WordPress, many of them are fully featured cloud-based services that run independently of WordPress.
You have multiple types of WordPress site security options based on the type of service and coverage you need. It’s a confusing decision, even for tech-savvy folks.
What we need to clarify upfront is that the “best WordPress security plugin” is not always going to be a plugin.
Many of these security services are fully-featured security solutions that reside on external servers and are available for any website platform, not just WordPress. They may offer a plugin to interface with their service, however.
Some are offered as fully featured plugins that you can just install and run with. We’ll make that distinction clear and what’s involved as we review each service.
What’s more, some of our top recommendations fall into several categories because they offer multiple means of security, i.e., Wordfence gives you an all-in-one solution for a WAF (Web Application Firewall), malware scanning, and site integrity features.
Sucuri Security is a global leader in WP website security and our pick for the best WAF — as well as a solid choice for malware scanning (see our best malware scanner winners below).
The Sucuri Security Platform includes a top-notch, cloud-based WAF, malware and blacklist monitoring and cleanup, and security monitoring at WordPress core and server levels.
What is a DNS or cloud-based WAF?
A DNS (Domain Name Resolution) firewall protects against attacks in a vulnerable area of the internet that can compromise your website or application before traffic even finds its way to your hosting server. Think of it as posting additional sentries at the gate to your driveway, vs inside your front door.
Sucuri is an excellent option if you’re looking for combined WAF and malware protection. After testing several security solutions, this is the one we opted for on We Rock Your Web. We’ve so far had one major malware attack that Sucuri successfully analyzed and defeated.
Sucuri also saves your activity monitoring log in the Sucuri Cloud (if you take advantage of the additional WP plugin interface) so that hackers can’t delete your files. While expensive, Sucuri requires little legwork because most of the scanning and back-end work is either automated or via a single-click process.

Pricing
The following pricing is for one website for its security platform, which includes malware protection. The price goes down a bit if you only want the firewall, but we recommend against that. You can also save by paying annually.
Cloudflare is a robust content delivery network (CDN) that offers a free WordPress plugin, which gives you a one-click installation of settings specifically developed for the WordPress platform. With the free version, you get a strong WAF with protection against DDoS attacks and automatic cache purging.
Cloudflare offers higher level DDoS protection with its paid plans. If you’re looking for application-level security scans in addition to a WAF, you’re out of luck here. Cloudflare doesn’t offer malware protection, blacklist removal, security, or monitoring for file changes.

Imperva (formally Incapsula) is another CDN like Cloudflare that gives you a powerful DNS-level WAF and other security features for e-commerce and sites that deal with sensitive data (Incapsula is also one of our top picks for site integrity features).
Imperva can also help your website load faster since their servers will absorb much of the bandwidth (and clean it) before it hits your server.
Their control panel gives you detailed information on each hacking attempt, and it allows you to act on that information. Imperva’s standout security features include DDoS protection, SQL injection protection, XSS attack protection, and backdoor protection.
It also does a great job of protecting your site from spam, malicious bots, and the Open Web Application Security Project’s Top 10 Vulnerabilities. Imperva, however, doesn’t offer application-level security scans, like malware and blacklisting.

What is spamvertising?
Spamvertising is essentially spam that’s used to advertise a product or service. For example, you’ve probably moderated comments on your website where they at first appear to be a legitimate engagement in your article’s topic, but upon closer inspection they are simply posting so they can plant a backlink to their website or service.

6Scan is an old-timer in the security world and was the first automated security suite. This WordPress security solution has a decent set of features but isn’t quite up to par with the top players.
