If you’ve got a WordPress site, you’ll already know it’s a fantastic tool for getting your business, blog, or shop up and running online. It’s easy to use, flexible, and packed with features — but let’s not kid ourselves, it’s not all sunshine and roses. Just like a house with the doors wide open, a poorly secured WordPress site can attract the wrong kind of visitors. Hackers, bots, and all sorts of online riffraff are always sniffing about, looking for gaps they can squeeze through — whether that’s an outdated plugin, a dodgy theme, or a weak login password.
That’s why keeping your WordPress or WooCommerce site secure isn’t just a one-time job — it’s something you’ve got to stay on top of.
And one of the best ways to do that? Regular vulnerability scans. Yep, giving your WordPress or WooCommerce site a proper once-over to check for security holes, malware, or suspicious activity that might be lurking under the bonnet.
So, let’s roll up our sleeves and get stuck in. We’ll walk you through how to scan your WordPress site for vulnerabilities. Whether you're running a side hustle or a growing online business, a bit of security know-how goes a long way in keeping the digital riffraff out and your site running smoothly.

Why Bother?
Now, you might be thinking, "Why should I worry about with this techy stuff?"
Well, let me tell you, it’s better than waking up to find your WordPress or WooCommerce site’s been hacked and your visitors are getting bombarded with dodgy links. A quick scan now and again can save you a heap of trouble later. It’s like checking your roof before winter – a bit of effort now saves a fortune down the line.
Tools for the Job
You don’t need to be a tech wizard to get started. There are plenty of tools out there to give your WordPress site a once-over:
Wordfence
Wordfence is one of the most popular WordPress security plugins out there, and for good reason. It comes with a powerful malware scanner that checks your core files, plugins, and themes for anything dodgy. Found an old plugin that’s not been updated in ages? Wordfence will let you know. Someone trying to guess your login? It’ll block ’em faster than you can say “WP”
It also checks for weak passwords, suspicious code, and other vulnerabilities that hackers love to exploit. You even get real-time alerts, so if anything untoward kicks off, you’ll be the first to know. Think of Wordfence as a proper guard dog for your website — always on, always watching, and not afraid to sink its teeth into troublemakers.
Sucuri Security
Sucuri is proper handy, especially if you want something a bit more advanced. It’s not just a scanner – it’s a full-blown security suite. It'll check your site for malware, keep an eye out for outdated software, and let you know if your site’s been blacklisted anywhere online (which can affect your SEO without you even knowing).
And if you’re feeling a bit fancy, there’s a firewall option too. That means your site gets an extra layer of protection, filtering out threats before they even reach your server. It’s like having a bouncer on the door who checks IDs before letting anyone into your site. Ideal if you’re running an online shop or handling customer data — or if you just want to sleep better at night knowing you’ve got your digital defences sorted.
WPScan
Now this one’s a bit of a hidden gem. WPScan doesn’t mess about — it’s made specifically for WordPress, and it knows the ins and outs like a Yorkshire farmer knows every stone wall in his field. It uses a massive, regularly updated database of known vulnerabilities in WordPress core, plugins, and themes. So if there’s a known hole in your site, WPScan will sniff it out sharpish. It’s especially useful for developers or site managers who want to do proper audits and stay ahead of the game. There’s even a free API for light scanning, and paid options if you want the full works.
How to Scan Your WordPress Site
Right then, you’ve picked your security plugin — whether it’s Wordfence, Sucuri, or WPScan — now it’s time to roll up your sleeves and put it to good use. Installing a plugin’s one thing, but if you just leave it sitting there doing nothing, you’re no better off than before. Here’s how to get your site website scanned for vulnerabilities.
Step 1: Install a Security Plugin
First things first — get your plugin installed and activated. Head to your WordPress dashboard, go to Plugins > Add New, search for your chosen tool (Wordfence, Sucuri, or WPScan), and click Install Now, then Activate.
And don’t just sit there admiring the pretty graphs and dashboards. Get stuck in, because this is where the real work begins.
Step 2: Run the Scanner
Most security plugins have a big, shiny button that says something like “Start Scan” or “Scan Now.” Click it. Go on — give it a bash. The plugin will now go through your site with a fine-tooth comb, checking for anything vulnerabilities such as:
- Outdated themes or plugins
- Malware or suspicious code
- Weak passwords or login attempts
- Files that look like they’ve been tampered with
Step 3: Check the Results
Once the vulnerabilities scan’s done, you’ll get a report. Don’t panic if it flags a few things — that’s its job. Most of the time, it’s something simple like:
- A plugin that needs updating
- A theme that’s no longer supported
- A file that shouldn’t be there
- A user account you don’t remember creating
The Known vulnerabilities scanning plugin will usually give you plain-English advice on what to do next. It might suggest deleting or replacing a file, updating your WordPress core, or tightening up your login security. Just follow the steps and your site will be in much better nick.
Step 4: Keep an Eye Out
Now here’s the bit most folk forget — don’t just do it once and forget about it. Hackers never sleep. They’re always poking about, looking for easy targets. So set up regular scans, either weekly or even daily, depending on how active your site is. And keep your plugins, themes, and WordPress version up to date. Updates often include important security fixes — and ignoring them is like leaving your front door unlocked with a big sign that says “Come on in!”
Extra Tips for Peace of Mind
Once you’ve scanned your site and patched up any holes, don’t stop there. Website security isn’t just a “set it and forget it” job — it’s something you’ve got to stay on top of. Think of it like locking up your house at night. You wouldn’t do it once and call it a day, would you? Here are three more simple but powerful habits every WordPress site owner should get into.
? Update Regularly
Your plugins, your themes, and WordPress itself — keep the whole lot up to date. Every time a developer releases an update, there’s usually a reason. Sometimes it’s a shiny new feature, but more often than not, it’s a security fix for something a hacker has already found and started exploiting.
An outdated plugin or theme is like leaving your front door wide open with a sign saying “Come on in and help yourself.” Hackers don’t need to be clever — they just look for sites that haven’t been updated and walk right in.
So make it a habit: log in once a week, check for updates, and hit that update button. Or set up automatic updates for trusted plugins if you want one less thing to worry about.
? Back Up Your Site (Just in Case)
Let’s be honest — sometimes, despite your best efforts, things still go a bit pear-shaped. A plugin clash, a dodgy file, or even a slip of the mouse can bring your site crashing down. That’s why having a recent backup is an absolute lifesaver.
A good backup means you can restore your entire site — content, images, settings, the lot — in minutes, not days. No stress, no drama.
There are loads of great plugins for this, like UpdraftPlus, BackupBuddy, or your hosting provider might already do daily backups for you. Just make sure you know how to restore it if needed. A backup’s no good if it’s just sat there collecting dust and you’ve no clue how to use it.
? Use Strong Passwords (No More “password123” Rubbish)
If you’re still using “admin” as your username and “password123” as your login, we need to have words. Hackers love those easy targets — they use bots that try thousands of combinations in seconds. It’s called a brute force attack, and if your login details are weak, it won’t take long for them to get in.
Instead, use long, unique passwords that mix letters, numbers, and symbols. Can’t remember them all? Don’t even try. Just use a password manager like LastPass, Bitwarden, or 1Password — they’ll store everything securely so you don’t have to.
And while you’re at it, turn on two-factor authentication (2FA). That way, even if someone does guess your password, they’ll still need access to your phone to log in.
