Does Wordfence Slow Down A WordPress Website?
7-layers of Security for Your WordPress Site
Your website needs the most comprehensive security to protect it from the constant attacks it faces everyday.
A security plugin is like a suit of armor. Dealing with a security plugin that slows down your website is like putting on a suit of armor that you can barely move in. Sure, you might be safe from attacks, but you’re also struggling to do what you need to do. A good security plugin for WordPress, like a well-crafted set of armor, should be able to offer protection without limiting your movement.
In this article, we’ll take a closer look at Wordfence and explore how it might be dragging down your website’s performance. We’ll delve into issues like server resources and its impact on page load times. We will also offer alternatives that can help you keep your website secure and running smoothly. Let’s get started!
Optimizing performance by configuring Wordfence correctly is often advised, but it can be a daunting task. A regular user shouldn’t have to decide what the appropriate security level for their website is. Although Wordfence has made efforts to enhance performance, it did it at the expense of compromising site security. We recommend installing MalCare, a security plugin that secures your site without increasing page load speed.
Wordfence is a popular security plugin for WordPress that has faced criticism for causing significant performance issues for websites. In fact, some web hosts prohibit the use of Wordfence due to these issues, which can result in server resource warnings and slow page load speeds.
Despite attempts to mitigate these performance issues in subsequent updates, some users may find that the changes actually lower the level of security provided by Wordfence. This is because some of the features that improve performance may compromise the plugin’s ability to detect and prevent security threats.
While configuring Wordfence settings can help improve performance to some extent, it’s not always the best solution. More often than not, it’s at the expense of actual security.
How does Wordfence slow down a WordPress site?
There are two types of issues that make Wordfence affect a site’s speed and performance. Let’s break them down.
Wordfence features that affect performance
The Wordfence malware scanner utilizes your website’s resources to scan for malware. If your website has a lot of heavy assets, such as images and other media files, the scanning process may take longer and require more resources to find any potential malware.
To address this issue, Wordfence offers the option to perform a limited scan instead of the standard scan, which can be especially useful for high-traffic sites. However, it’s worth noting that this may not be a perfect solution, and there are some limitations to the effectiveness of the limited scan. In the next section, we’ll explore some of the drawbacks of using a limited scan.
One of the primary ways that Wordfence protects your website is through its firewall. The firewall is designed to analyze incoming traffic and block any suspicious traffic based on predefined rules. While these rules are created to prevent attacks, they can also have a negative impact on your website’s performance by increasing the server load. In some cases, they may cause delays in the processing of legitimate requests.
The impact of the firewall on website performance can vary depending on various factors:
- Size of your website
- Server resources available
- Complexity of the firewall rules
In earlier versions of Wordfence, all traffic to your website was scanned for malicious activity. However, in recent versions, the plugin now focuses on scanning traffic for certain parameters and is mainly configured to block brute force bots.
While protecting against brute force attacks is crucial, it’s worth noting that only a small percentage of successful attacks on WordPress sites are due to poor login security. In fact, most successful attacks are due to vulnerabilities, such as SQL injections and XSS attacks, which are different from brute force attacks.
Furthermore, limiting traffic to your website is also recommended to improve security and performance. We’ll talk about why this is not a great solution, in a later section.
Wordfence’s caching can also slow down your site. Ironic, we know.
WordFence is not stopping the security issues that slow down your site
It’s important to note that Wordfence may not catch all malware on your site.
While Wordfence has a comprehensive malware signature database, which they use to detect malware on your site, the problem is in the detection mechanism: signature-matching. Signature-matching relies on the database being updated and 100% comprehensive, which can never be the case.
Zero-day malware attacks and malware with subtle differences can escape under this mechanism. So malware could be one of the factors contributing to slower website performance.
Bots are insidious malware that hammer sites for various reasons. Maybe it is a brute force attack bot trying to break into your wp-admin. Or it could be a competitor adding a thousand items to your checkout page in order to scrape product details.
Repeated requests from bad bots can cripple a site because of the load they put on the server. Wordfence may not be blocking all the bad bots, because some of them cleverly masquerade as good bots, like uptime or search engine bots to pass filters undetected.
Therefore, bot attacks may not be filtered out by Wordfence, which can lead to spikes in server requests and further slow down your site.
We know it is dismal that the Wordfence malware scanner (which is slowing down your site) might not be catching malware (which is also slowing down your site). Similarly, the firewall that is slowing down your site while analyzing traffic may not be keeping out bots that are paralyzing your site with repeated requests. Talk about a potential double whammy of security and performance issues in one fell swoop.
Can you optimize Wordfence configurations for speed?
The short answer is: Sure. But, it’s like putting a bandaid on a leaky pipe. It’s not solving the main issue. Ideally you need to replace the pipe.
We’ll explore some of the solutions other websites will suggest. Then we’ll tell you what they’re not telling you.
Turn off live traffic
For high-traffic sites, it’s advised to switch from the live traffic option in the firewall settings from All Traffic to Security Only. However, this may not be the most effective solution. When you have live traffic on your site, the firewall analyzes all the incoming traffic—as it is supposed to do.
But if you turn it off to speed things up, you’ll lose that security protection. Ideally, Wordfence should not be using your site server resources to analyze traffic, but here we are.
Turn on low resource scanning
Wordfence has introduced a setting which allows you to lengthen the scanning duration 2-4x in order to reduce resource usage at any one point. We actually think this may be a good idea, although it is still not ideal to use server resources for scanning at all.
Install a speed plugin
Another popular recommendation is to install a speed plugin. We’d agree. In fact, a speed plugin such as Airlift can be considered an essential for WordPress sites. However, you should not have to install it to compensate for a slow security plugin.
A speed plugin optimizes certain aspects of your site to make it faster without manual effort on your part. It has features like a CDN, caching, and minification of code and images. It cannot fix performance issues caused by security plugins using up server CPU to protect the site.
Upgrade hosting specs
If you have a basic hosting tier or your server performance is not optimal, upgrading the hosting tier is the recommended solution. Depending on your resources, this might be difficult. And honestly, if a lower tier otherwise works for your site without issues, Wordfence shouldn’t be the only factor that makes you upgrade.
What’s a foolproof way to improve your website’s performance?
If you’ve tried all the tricks to fix Wordfence problems, the best option is to switch to another security plugin. MalCare is the way to go.
For starters, you can conduct a scan that doesn’t affect your server resources because MalCare scans use their own servers. There is a one-click automated removal of malware that helps you remove the malware that Wordfence didn’t catch. There is also a top-notch firewall that safeguards your site from future attacks. It really takes care of all critical security features.
What are some other ways to optimize your website’s performance?
If uninstalling Wordfence hasn’t improved your performance, Wordfence may not have been the issue. Try out these methods to optimize your site:
- Update plugins and themes: Ensure that your website’s plugins and themes are up to date as outdated ones can impact website speed and performance.
- Limit plugins: Installing too many plugins can significantly slow down your website’s speed. Only use the necessary plugins for your website.
- Minimize external scripts: External scripts such as ads, social media widgets, and tracking scripts can significantly slow down your website’s speed. Only use the necessary external scripts to avoid impacting your website’s performance.
There are plenty of reasons why a site may be slow to load, and ways to fix those issues just as well.
How to choose the best security plugin for your website?
Ensuring the security of your website is crucial in today’s digital landscape. Here are some questions you probably have about choosing a different security plugin from Wordfence.
What are the critical features of a security plugin?
The critical features of a security plugin include malware scanning, malware removal and a robust firewall. If a security plugin doesn’t have good scanner, firewall and removal features, they’re not worth your salt. Additionally, there are other features that would be good to have like alerts, brute force login protection, two-factor authentication.
Why shouldn’t you compromise on those security features?
Compromising on the features of a security plugin can lead to disastrous consequences, including data breaches and site downtime. They’re crucial for site protection.
Can other security plugins have the same performance issues as Wordfence?
It’s possible that other security plugins may also have similar issues to Wordfence, which can lead to performance issues and leave your site vulnerable to attacks. Sucuri immediately comes to mind. It’s essential to choose a reliable and robust security plugin like MalCare to ensure optimal website security.
Why is MalCare the best?
MalCare uses its own servers to protect your site, so it doesn’t affect your server resources. It also offers an advanced firewall that protects your site from malware and bots that can slow it down.
