WordPress powers over 43% of all websites on the internet, which makes it an attractive target for hackers, bots, and cybercriminals. We have been building and managing WordPress sites for the past 10 years, and I can tell you from experience that security isn’t something you sort out after a breach happens. It’s something you build into your site from day one.
Last year, a client rang me in absolute panic. Their e-commerce site had been compromised, customer data was at risk, and they were staring down the barrel of GDPR fines that could have bankrupted their business. The worst part? The breach could have been prevented with some basic security measures that would have taken less than an hour to implement.
That conversation stuck with me, and it’s why I’m writing this guide today. Whether you’re running a personal blog, a business website, or a full-blown online shop, these 25 WordPress security tips to keep your website safe will help you lock down your site and sleep better at night.
Understanding Why WordPress Sites Get Hacked
Before we jump into the practical tips, it’s worth understanding why WordPress sites are such popular targets. It’s not because WordPress itself is inherently insecure. The platform is actively maintained by thousands of developers and receives regular security updates.
The real vulnerabilities come from three main sources: outdated plugins and themes, weak passwords, and misconfigured hosting environments. Hackers use automated tools that scan thousands of websites per hour looking for these common weaknesses. Once they find a vulnerability, they can inject malicious code, steal data, or use your server to launch attacks on other sites.
The good news? Most attacks can be prevented with straightforward security practices that don’t require a computer science degree to implement.
1. Keep WordPress Core Updated
This might sound obvious, but you’d be surprised how many sites run outdated versions of WordPress. Every update includes security patches that fix known vulnerabilities. When you delay updates, you’re essentially leaving the front door unlocked.
WordPress makes this easy with automatic updates for minor releases. You can enable automatic updates for major releases too, though I’d recommend testing these on a staging site first if you’re running a business-critical website. The WordPress Updates documentation provides detailed guidance on managing updates safely.
Set a reminder to check for updates weekly. It takes two minutes and could save you from a catastrophic breach.
2. Update Plugins and Themes Religiously
Here’s where most security breaches actually happen. Outdated plugins are the number one entry point for hackers. I’ve seen sites running plugins that haven’t been updated in three years, with dozens of known security flaws just waiting to be exploited.
Before updating, check the plugin’s compatibility with your WordPress version and read through recent reviews. Occasionally, updates introduce bugs, so having a recent backup before you update is sensible practice.
Delete any plugins you’re not actively using. Every inactive plugin is potential security risk sitting on your server. The same goes for themes. Keep one or two backup themes if you must, but delete the rest.
