WordPress powers more than 43% of all websites on the internet. That reach is exactly why it is also one of the most targeted platforms by cybercriminals. If your business runs on WordPress, security is not something to think about once and forget. It is an ongoing part of keeping your website, your data, and your customers safe.
The good news is that WordPress is genuinely well-maintained and secure. The risks tend to come from elsewhere: outdated plugins, weak passwords, and poor hosting choices. Most security breaches are preventable. This guide walks you through the most common WordPress security risks, the best practices every UK business should follow, and when it makes sense to get professional support rather than go it alone.
Is WordPress Actually Secure?
WordPress itself is robust and actively maintained by a dedicated security team. In 2024, only seven vulnerabilities were found in WordPress core, and none of them posed widespread risk. The security concerns most businesses hear about do not stem from WordPress itself. They come from plugins, themes, and user behaviour.
WordPress has a security team that monitors threats around the clock, patches vulnerabilities quickly, and pushes minor security updates automatically to all installations. Major organisations including the BBC and thousands of UK businesses trust it to run their online presence. But WordPress’s popularity is a double-edged sword. Because it powers such a large proportion of the web, attackers build automated tools specifically designed to probe WordPress installations for weaknesses. The platform is not the weak point. The decisions made around it often are.
The Biggest WordPress Security Risks Facing UK Businesses in 2026
Most successful attacks on WordPress sites do not exploit flaws in WordPress core. They exploit vulnerable plugins, outdated software, weak credentials, and poor hosting environments. Understanding where the real risks lie is the first step to protecting your site effectively.
Plugin and Theme Vulnerabilities
Plugins and themes account for 96% of all WordPress vulnerabilities, according to Patchstack’s State of WordPress Security 2025 report. In 2024 alone, 7,966 new vulnerabilities were discovered across the WordPress ecosystem. That works out at 22 new security flaws every single day.

The most common types include cross-site scripting (XSS), broken access control, and SQL injection. In some cases, these vulnerabilities allow attackers to access a site’s database without even needing login credentials. A single widely-used plugin with an unpatched flaw can expose hundreds of thousands of sites simultaneously.
What makes this especially risky is that many businesses install plugins, forget about them, and never apply updates. Some plugins are abandoned by their developers entirely, meaning vulnerabilities are never patched. In 2024, over 1,600 plugins were removed from the official WordPress repository for unresolved security issues or developer inactivity.
Brute Force Attacks
Brute force attacks use automated bots to repeatedly guess login credentials until they find the right combination. Wordfence blocked more than 55 billion password attack attempts against WordPress sites in 2024 alone, averaging 65 million attempts every day. If your login page is accessible and your password is weak, it is only a matter of time. [Source: Wordfence, 2025]
Attackers specifically target the default WordPress login URL (/wp-admin), making this one of the most common entry points. Changing your login URL, limiting login attempts, and enabling two-factor authentication all make a significant difference here.
Outdated WordPress Core, Plugins, and Themes
Every piece of software on your WordPress installation needs to be kept up to date. When a vulnerability is discovered and a patch is released, any site still running the old version becomes a known, publicly documented target. Attackers scan for sites running outdated versions and exploit them at scale. Approximately 35% of known WordPress vulnerabilities remain unpatched across active installations, meaning a large number of sites are knowingly exposed. [Source: Wordfence, 2025]
Weak Credentials and Poor Access Control
Default usernames, weak passwords, and too many users with administrator-level access are all common entry points. A compromised admin account gives an attacker complete control of your website. Every user account should have only the level of access they actually need: editor, author, or subscriber rather than admin, unless admin access is genuinely required. This is one of the simplest security measures, and one of the most frequently overlooked.
WordPress Security Best Practices Every UK Business Should Follow
Securing a WordPress site does not require a deep technical background. Most of the most effective measures are straightforward to implement, especially with the right hosting and maintenance support in place. Here is what every business running WordPress should have covered.
Keep WordPress, Plugins, and Themes Updated
This is the single most effective thing you can do. Apply updates to WordPress core, plugins, and themes promptly, ideally within 48 hours of a security release. WordPress 6.6 and above supports automatic plugin updates with rollback capability, which reduces the risk of a broken update taking your site down. Enable this where you can.
Also remove any plugins and themes you no longer use. Inactive software still presents a security risk even if it is not actively running. If a plugin has not been updated by its developer in the last six months, consider finding a well-maintained alternative.
Use Strong Passwords and Two-Factor Authentication
Every account with access to your WordPress dashboard, including editors and contributors, should use a unique, strong password of at least 16 characters. Two-factor authentication (2FA) adds a second layer of verification, meaning a stolen password alone is not enough to get in.
This matters beyond the obvious security benefit. The ICO (Information Commissioner’s Office) has made clear that failing to implement multi-factor authentication can result in significant penalties under UK GDPR. A business was fined £3.07 million in 2025 partly on these grounds. For UK businesses handling any personal data through their website, this is not optional.
Audit and Limit Your Plugins
Before installing any plugin, check when it was last updated, how many active installations it has, and what its reviews say. Keep your plugin count lean. Every plugin you add is another potential vulnerability. Aim to review what is installed on your site every few months and remove anything redundant or abandoned.
Install a Web Application Firewall
A web application firewall (WAF) filters incoming traffic and blocks malicious requests before they reach your site. Tools like Wordfence and Cloudflare offer well-regarded WAF options for WordPress. A good firewall is particularly effective at stopping brute force attacks and known exploit attempts, and it takes very little ongoing management once it is set up correctly.
Run Regular, Tested Backups
A backup does not prevent an attack, but it can be the difference between a minor incident and a major disaster. If your site is compromised, a clean and recent backup means you can restore quickly with minimal data loss. Store backups in a separate location from your hosting environment, and periodically test them to confirm they can actually be restored. A backup you have never tested is not a backup you can rely on.
Choose Secure, Well-Managed Hosting
Your hosting environment is your first line of defence. Look for a provider that includes server-side firewalls, malware scanning, daily backups, and support from people who actually understand WordPress. Our business website hosting is built around these standards, because the hosting layer matters as much as anything else on this list.
Cheap shared hosting often cuts corners on security configuration. Managed WordPress hosting takes a significant chunk of the ongoing security burden off your plate, which is worth a great deal if your team does not have the time or technical knowledge to stay on top of it.
What to Do If Your WordPress Site Gets Hacked
If your site has been compromised, act quickly. The steps you take in the first few hours will make a significant difference to how serious the damage ends up being.
- Contact your hosting provider immediately. Most managed hosts have a process for security incidents and can help contain the problem quickly.
- Take the site offline temporarily if possible, to prevent malware spreading to visitors or further data being exposed.
- Restore from a clean backup if you have one that pre-dates the breach.
- Change all passwords: WordPress admin, hosting control panel, FTP, and database credentials.
- Run a malware scan using a tool like Sucuri or Wordfence to identify and remove any injected code.
- Review all user accounts and remove anything unfamiliar or unexpected.
- Establish how the breach happened so you can close the vulnerability and prevent it happening again.
If you do not have a recent clean backup and your site is heavily compromised, professional malware removal is usually the most efficient route. Trying to manually clean an infected WordPress installation without the right tools is time-consuming and easy to get wrong.
WordPress Security and UK GDPR: What Your Business Needs to Know
For UK businesses that collect, process, or store personal data through their website, security is a legal matter as well as a practical one. A WordPress security breach that exposes personal data must be reported to the ICO within 72 hours under UK GDPR.
UK GDPR requires businesses to take appropriate technical and organisational measures to protect personal data. A breach resulting from avoidable security failings, such as an unpatched plugin or the absence of multi-factor authentication, can attract regulatory scrutiny and substantial financial penalties. The ICO’s record £14 million enforcement action in 2025 is a reminder that this is not a theoretical risk for UK businesses.
This applies to any site that includes contact forms, ecommerce functionality, membership areas, or any mechanism that collects information from visitors. If that describes your website, your security posture needs to reflect it.
Should You Handle WordPress Security Yourself or Get Professional Support?
Many business owners manage their own WordPress security reasonably well. But as the threat landscape grows more sophisticated, and as the consequences of a breach become more serious, there is a strong case for having professional support in place.
If you are comfortable with the basics, keeping on top of updates, using strong credentials, running backups, and working with a reliable host, that covers a lot of ground. But the details matter. Knowing which plugins to trust, spotting unusual activity before it becomes a breach, and responding quickly when something goes wrong are all easier with someone who understands WordPress at a technical level.
Yellow Circle’s website maintenance service handles the ongoing security management that most businesses do not have the time or technical knowledge to stay on top of. That includes regular updates, malware scanning, daily backups, and responsive support when things go wrong. It is not just about peace of mind. It is about protecting your website as a commercial asset.
If you are planning a new website, security is also part of how we approach WordPress development from the start. Clean code, sensible plugin choices, and a properly configured hosting environment all make a significant difference before a single visitor ever lands on your site.
WordPress Security FAQs
Is WordPress safe for business websites?
Yes. WordPress core is actively maintained by a dedicated security team and is trusted by some of the world’s largest organisations. The risks most commonly associated with WordPress come from plugins, themes, and poor configuration choices, not from the core platform itself. A well-managed WordPress site is a genuinely secure one.
How often should I update my WordPress plugins?
Ideally, as soon as updates become available. As a minimum, check for updates at least once a week, and apply any security-related updates within 48 hours of release. Enabling automatic updates with rollback, available from WordPress 6.6, makes this much easier to manage in practice.
Do I need a security plugin for WordPress?
A security plugin adds useful layers of protection including a firewall, login protection, malware scanning, and activity logging. Wordfence and Sucuri are both well-regarded options. That said, a security plugin alone is not a substitute for keeping software updated, using strong credentials, and running on a secure hosting environment. It is one layer of a wider approach, not a complete solution by itself.
Can WordPress sites be hacked easily?
A well-maintained WordPress site with strong credentials, up-to-date software, a firewall, and secure hosting is genuinely difficult to compromise. The sites that get hacked tend to have one or more obvious weak points: an outdated plugin with a known vulnerability, weak or reused passwords, or a poorly configured hosting environment. Most successful attacks exploit avoidable problems.
What should I do if my WordPress site has been hacked?
Contact your hosting provider straight away, take the site offline if you can, restore from a clean backup, change all passwords, and run a malware scan. If you do not have a recent backup, professional malware removal is usually the most efficient route. Once your site is clean, carry out a thorough review to find out how the breach happened and close the vulnerability.
Keeping Your WordPress Site Secure: The Bottom Line
WordPress security is not a one-time job. It is an ongoing commitment to keeping your site, your customers’ data, and your business protected. The most common breaches are preventable, and most of the measures that prevent them are not complicated. What they require is consistency: regular updates, good credential practices, reliable backups, and a hosting environment you can trust.
If you would rather hand the technical side of this over to a team who know WordPress inside out, our website maintenance service is built exactly for that. Get in touch and we will start with an honest conversation about where your site currently stands.
