You built your WordPress site. You picked a theme, added some pages, maybe even set up a blog. But here’s a question most beginners never think to ask: is your site actually safe?
WordPress powers over 40% of all websites on the internet. That makes it the most popular platform in the world – and the most targeted. Hackers do not go after your site because of who you are. They run automated scripts that scan millions of sites looking for easy targets. If your site has a weakness, it will be found.
The good news? You do not need to be a developer to check if your site is secure. In this guide, you will learn what WordPress security actually means, what can go wrong if you ignore it, and how to run a free security scan using WP Vanguard at wpvanguard.com – including how to read the results and fix common issues.
What Does WordPress Security Actually Mean?
Security is not just about having a strong password (though that helps). WordPress security covers everything that keeps bad actors from accessing, damaging, or taking over your site.
Think of it like your home. A strong lock on the front door is important. But so is locking the back door, closing the windows, and not leaving a spare key under the welcome mat. Website security works the same way – there are multiple entry points, and any one of them can be a problem.
The Three Main Areas of WordPress Security
- Access control – Who can log in to your site and with what permissions
- Software vulnerabilities – Outdated plugins, themes, or WordPress core that have known security holes
- Malware and injections – Malicious code that has already been placed on your site without your knowledge
Most beginners only think about the first one. The second and third are where real breaches happen.
What Can Go Wrong If You Ignore Security?
Before you learn how to check your site, it helps to understand what you are actually protecting against. Here are the most common things that happen to unprotected WordPress sites.
1. Your Site Gets Hacked
This is the obvious one. A hacker gains access to your WordPress admin and can do whatever they want – change your content, steal data, or completely delete your site. In many cases, site owners do not even know it happened for weeks.
2. Malware Gets Installed
Malware is software that runs on your site without your permission. It might redirect your visitors to other sites, display ads you never approved, or quietly collect information from anyone who visits. Your site can look completely normal to you while something harmful runs in the background.
3. You Get Blacklisted by Google
When Google detects malware on a site, it shows a warning to anyone trying to visit it. You have seen these before – the big red “This site may harm your computer” screen. Once that happens, your traffic drops to near zero until you get the malware removed and submit a reconsideration request. This process can take weeks.
4. Spam Gets Sent From Your Domain
Attackers often use compromised sites to send spam emails. Because the spam comes from your domain, your email reputation gets destroyed. Even legitimate emails you send later – like newsletters or order confirmations – may end up in spam folders.
5. Your Hosting Account Gets Suspended
Most hosting providers monitor for malware and abuse. If your site is found to be a source of malicious activity, your hosting account can be suspended without warning. This takes your entire site offline until you clean it up.
A compromised WordPress site does not just hurt you – it can affect every visitor who lands on it. Security is not optional.
How to Check Your WordPress Site With WP Vanguard
WP Vanguard is a free tool that scans your WordPress site and tells you exactly where you stand on security. You do not need to install anything. You do not need to log in to your WordPress admin. You just enter your site’s URL and get a report.
Here is how to use it, step by step.
Step 1: Go to wpvanguard.com
Open your browser and go to wpvanguard.com. You will see a simple search bar on the homepage. This is where you enter your site’s domain.
Step 2: Enter Your Domain Name
Type your website’s address into the search bar. You can use just the domain name without “https://” – for example, myblog.com or mystore.com. Then hit the scan button.
WP Vanguard runs a surface-level scan for free. This checks your site from the outside – the same way a hacker would first look at it – and flags the most common vulnerabilities.
Step 3: Wait for the Scan to Complete
The scan usually takes under a minute. It checks things like your SSL certificate, WordPress version, login page exposure, known vulnerability databases, and more. You will see a loading indicator while it runs.
Step 4: Read Your Security Grade
Once the scan is done, you get a security grade – a score out of 100, shown prominently at the top of the report. Think of it like a report card for your site’s security.
| Score Range | What It Means |
|---|---|
| 80 – 100 | Good. Your site follows basic security practices. Still worth reviewing the details. |
| 60 – 79 | Fair. Some issues to address, but nothing urgent. Fix them soon. |
| 40 – 59 | Poor. Multiple problems that should be fixed within the week. |
| Below 40 | Critical. Your site is at real risk. Address these issues today. |
Do not panic if your score is low. A lot of sites have issues they are not even aware of. The point of the scan is to find them before someone else does.
Understanding What Each Check Means
The scan report breaks down your results into individual checks. Here is what each one means in plain English.
SSL Certificate
SSL is the technology that makes your site load with “https://” instead of “http://”. It encrypts data between your visitors and your server, so no one can intercept it in transit. If your site does not have SSL – or if your certificate is expired – browsers will show a “Not Secure” warning to your visitors.
What to do if this fails: Contact your hosting provider. Most hosts today offer free SSL certificates through Let’s Encrypt and can enable it in one click from your hosting dashboard.
WordPress Version
Older versions of WordPress have known security vulnerabilities that are publicly documented. Attackers use automated tools to find sites running outdated versions and exploit those vulnerabilities. Running the latest version of WordPress is one of the simplest and most effective things you can do for security.
What to do if this fails: Log in to your WordPress admin, go to Dashboard, and run the update. Back up your site first if you have not done so recently.
Login Page Exposure
By default, every WordPress site has its login page at yourdomain.com/wp-admin. This is public knowledge. Automated bots constantly try to guess usernames and passwords on these pages in what is called a brute force attack. If your login page is easy to find and has no protections, your site is a more attractive target.
What to do if this flags: Install a security plugin like Wordfence or Solid Security (formerly iThemes Security). These can add login attempt limits, two-factor authentication, and optionally move your login URL to a custom address.
Plugin and Theme Vulnerabilities
This is one of the most important checks. Most WordPress hacks happen through outdated or vulnerable plugins and themes, not through WordPress itself. WP Vanguard checks your site against a database of known vulnerabilities and flags anything that matches.
What to do if this fails: Update all your plugins and themes immediately. If a plugin has a known vulnerability and no update is available, consider switching to a different plugin. An outdated plugin you no longer use should be deleted entirely, not just deactivated.
User Enumeration
WordPress has a default behavior that lets anyone find out your usernames through a publicly accessible URL. Attackers use this to get the first half of the login equation – your username – and then only have to guess the password. If user enumeration is enabled, it is easier to run automated attacks against your login page.
What to do if this flags: A security plugin like Wordfence or Solid Security can block user enumeration with a single toggle. It is usually in the settings under “login security” or “user enumeration protection.”
File Editing in Admin
WordPress has a built-in code editor in the admin panel that lets you edit theme and plugin files directly. While this might sound useful, it is also a major security risk. If anyone gains access to your admin area, they can use this editor to add malicious code to your site instantly.
What to do if this flags: You can disable the editor by adding one line to your wp-config.php file: define('DISALLOW_FILE_EDIT', true);. Many security plugins can also do this for you automatically.
Admin Username
If your WordPress admin account username is “admin”, you have already handed attackers half of what they need to get in. This is the default username for older WordPress installations and one of the first things automated tools try when brute-forcing your login.
What to do if this flags: Create a new admin account with a unique username, then delete the old “admin” account (assigning all content to the new account). This takes about five minutes but makes a real difference.
Simple Fixes You Can Do Right Now
After your scan, you may be looking at a list of issues and feeling overwhelmed. Do not be. Most common security problems have straightforward fixes, and you do not need to be a developer to apply them. Here is a priority list.
Priority 1: Update Everything
Updates are your first line of defence. Log in to your WordPress dashboard and go to Dashboard then Updates. Run updates for WordPress core, then plugins, then themes. Do them in that order. If you have not updated in a while, this one step alone can close several vulnerabilities.
Priority 2: Install a Security Plugin
A good free security plugin handles a lot of the technical work for you. Wordfence is the most popular option. Install it, activate it, and run a scan from within the plugin. It will flag any malware, weak passwords, or configuration issues specific to your site.
Priority 3: Enable Two-Factor Authentication
Two-factor authentication (2FA) means that even if someone guesses your password, they still cannot log in without a second verification – usually a code from an app on your phone. Both Wordfence and Solid Security offer free 2FA for WordPress logins. This is one of the highest-impact security improvements you can make.
Priority 4: Set Up Regular Backups
Security is not just about preventing attacks. It is also about recovering from them. A recent backup means that even in the worst-case scenario – complete site compromise – you can restore your site to a clean state. Plugins like UpdraftPlus make automated backups simple and free.
Priority 5: Use Strong Passwords
Your WordPress admin password should be long and unique – not a word from the dictionary and not something you use on other sites. WordPress has a built-in password generator that creates strong passwords automatically. Use it. And consider a password manager so you do not have to remember it.
How Often Should You Check Your Site’s Security?
Running a scan once is not enough. Security is ongoing. Here is a simple schedule to follow:
- Weekly: Check for plugin, theme, and WordPress core updates. Apply them.
- Monthly: Run a scan with WP Vanguard or your security plugin. Review any new flags.
- After any major change: If you install a new plugin, add a team member, or switch themes, run a scan to make sure nothing introduced a new vulnerability.
- Immediately: If your site starts behaving strangely – slow loading, unknown admin users, unexpected content appearing – scan it right away. These can be signs of a compromise.
What the Free Scan Does Not Cover
WP Vanguard’s free scan is a surface-level check. It looks at your site from the outside – the same perspective a hacker would have before attempting to get in. It is great for identifying the most obvious and common issues.
There are things it cannot see without deeper access:
- Malware that is hidden inside your theme or plugin files
- Suspicious code injected into your database
- Backdoors that an attacker may have already planted
- Server-level configuration issues
For those, WP Vanguard offers a deep scan option. If your free scan comes back with serious issues, or if you suspect your site has already been compromised, a deep scan is worth considering. It goes inside your WordPress installation and checks file integrity, database content, and more.
Security for Beginners: The Key Mindset Shift
Most beginners treat security as something you set up once and forget about. The reality is that security is maintenance – like changing the oil in your car. Your site is a moving target because the threats against it change constantly.
Plugin developers find new vulnerabilities and release patches. Attackers find new techniques. WordPress itself releases security updates. Staying current is the most reliable way to stay protected.
The good news is that the basics – updates, strong passwords, a security plugin, and regular backups – protect against the vast majority of attacks. Most sites are not targeted specifically. They are caught in wide automated sweeps looking for easy victims. A few simple precautions are usually enough to make your site an unattractive target.
Quick Recap
Here is everything covered in this guide, condensed into a checklist you can act on today:
- Go to wpvanguard.com and run a free scan on your site
- Review your security grade and the individual checks
- Update WordPress core, all plugins, and all themes
- Install Wordfence or another security plugin
- Enable two-factor authentication for your admin login
- Set up automated backups with UpdraftPlus or your host’s backup tool
- Change your admin username if it is still “admin”
- Schedule a monthly scan to stay on top of new issues
Security does not have to be complicated. Start with a scan, fix what it finds, and build the habit of staying updated. That alone puts you ahead of most WordPress site owners.
