Are WordPress Websites Secure?

Are WordPress websites secure? It is one of the most frequently asked questions about the platform, and one of the most frequently misunderstood. The short answer is yes: a properly maintained WordPress website is secure. But the full answer requires understanding what makes WordPress vulnerable when things go wrong, what protects it when they do not, and what the specific responsibilities are for anyone running a WordPress site.

This article gives you that full picture, without either dismissing the question or overstating the risk. WordPress security is a manageable, well-understood area. The businesses that experience problems are almost always the ones that have not followed a basic maintenance routine, not the ones that chose the wrong platform.

Why WordPress Has a Reputation for Security Issues

WordPress powers approximately 43% of all websites on the internet. That enormous market share has two consequences for security.

The first is that WordPress is the most attractive target for automated attacks. When a vulnerability is discovered in WordPress core or in a widely used plugin, the potential pool of affected sites is enormous, which makes it worth the effort of automated exploitation. This is a function of popularity rather than of any fundamental weakness in the platform.

The second consequence is statistical. When 43% of websites run on a single platform, the majority of compromised websites on the internet will be WordPress sites simply because the majority of websites on the internet are WordPress sites. This creates the impression that WordPress is inherently insecure when the reality is that WordPress sites are compromised at broadly similar rates to websites on other major platforms, adjusted for their share of the total.

The perception of a security problem is real. The nature of that problem is different from what most people assume.

What Actually Makes WordPress Sites Vulnerable

The vast majority of WordPress security incidents are not the result of fundamental weaknesses in the platform. They result from predictable, avoidable maintenance failures.

Outdated WordPress core

WordPress releases regular updates that include security patches for discovered vulnerabilities. Sites that do not apply these updates remain exposed to vulnerabilities that have already been publicly identified and for which automated attack tools already exist. Running an outdated version of WordPress is the equivalent of leaving a known unlocked door in an otherwise secure building.

Outdated plugins

Plugins are the most common source of WordPress security vulnerabilities. Because plugins are developed by a wide range of third parties with varying levels of security expertise, vulnerabilities are discovered regularly. A site with ten or twenty plugins installed, some of which have not been updated in months, has a correspondingly larger attack surface. As covered in the WordPress plugins article on this blog, keeping plugins updated and removing those no longer in use is one of the most important security habits a WordPress site owner can develop.

Outdated themes

Themes can contain security vulnerabilities in the same way plugins can, particularly themes that include large amounts of bundled functionality. An outdated theme from an inactive developer is a genuine risk. As covered in the WordPress themes article on this blog, choosing well-maintained themes and keeping them updated is part of a sound security approach.

Weak passwords and poor access control

Brute force attacks against WordPress login pages are extremely common. An administrator account with a weak or commonly used password is vulnerable to these attacks regardless of how well the rest of the site is maintained. Using strong, unique passwords, enabling two-factor authentication and limiting login attempts are all straightforward protections against this category of attack.

Poor hosting environments

The hosting environment has a significant effect on security. A shared hosting account on a server that is not properly configured, not kept updated, and not monitored for unusual activity is a less secure environment than well-managed dedicated or VPS hosting. In poorly configured environments, a security incident on another site sharing the same server can affect neighbouring sites. Choosing a reputable hosting provider with a credible security track record matters considerably.

Unnecessary plugins and abandoned software

Every inactive plugin sitting on a WordPress installation is a potential vulnerability. Even deactivated plugins can contain exploitable code in some circumstances. A clean, well-maintained plugin list, containing only what is actively needed and in use, reduces the attack surface considerably.

What Protects a WordPress Site

Regular updates

Keeping WordPress core, themes and plugins updated to their current versions is the single most impactful security action available and the one most directly within the control of the site owner or their developer. Most WordPress security incidents could have been prevented by a current update that was simply not applied.

Strong authentication

Strong, unique passwords for all user accounts, combined with two-factor authentication for administrator accounts, significantly reduces the risk of unauthorised access through the login page. Password managers make strong unique passwords practical for most people. Two-factor authentication is available through free plugins such as WP 2FA or Google Authenticator for WordPress.

A security plugin

Security plugins such as Wordfence, iThemes Security (now Solid Security), and Sucuri provide a range of protective measures, including web application firewall functionality, malware scanning, login attempt limiting, file integrity monitoring, and alerts for suspicious activity. A reputable, actively maintained security plugin adds a meaningful layer of protection and visibility to an otherwise well-maintained site.

HTTPS and SSL

Running the site over HTTPS with a valid SSL certificate encrypts data in transit between the server and the visitor’s browser. It does not protect against server-side vulnerabilities, but it does prevent traffic interception and is a baseline requirement for any serious business website. Most reputable hosting providers include free SSL certificates through Let’s Encrypt or equivalent services.

Regular backups

Backups are not a security measure in the sense of preventing an attack, but they are the most important recovery tool when one occurs. A site with current, tested, off-site backups can recover from a security incident in hours. A site without backups faces a much more difficult and potentially complete loss of its content and configuration. Plugins such as UpdraftPlus make automated, scheduled backups to cloud storage straightforward and free.

Limiting user access

WordPress has a role system that allows different levels of access to be assigned to different users. Assigning the lowest level of access that allows a user to do their job, rather than making everyone an administrator, limits the potential damage from a compromised account. Most content editors do not need administrator access and should not have it.

Good hosting

As noted above, the hosting environment matters. Managed WordPress hosting providers such as Kinsta, WP Engine and Flywheel include additional server-level security measures, automatic updates and malware scanning as part of their offering. For business-critical sites, the additional cost of managed hosting relative to shared hosting is almost always worthwhile.

Frequently Asked Questions

Is WordPress more vulnerable than other website platforms?

Not inherently. WordPress’s prevalence makes it a more attractive target for automated attacks, but a well-maintained WordPress site is not meaningfully more vulnerable than a well-maintained site on any other major platform. The security incidents that occur on WordPress sites are almost always the result of maintenance failures rather than fundamental platform weaknesses. A poorly maintained site on any platform is a security risk.

Do I need to update WordPress manually, or does it update itself?

WordPress can be configured to apply minor updates automatically, which it does by default for security-focused minor releases. Major version updates typically require manual action or explicit configuration to apply automatically. Plugin and theme updates do not apply automatically by default, though this can be enabled for individual plugins and themes from the WordPress admin dashboard. For business websites, a managed approach where updates are reviewed and tested before being applied, rather than fully automated, is generally preferable.

What should I do if my WordPress site is hacked?

The immediate priorities are to take the site offline if possible to prevent further harm, restore from a clean backup if one is available, change all passwords for all accounts associated with the site and hosting, and identify how the attack occurred so the vulnerability can be addressed before the site is restored. If a clean backup is not available, a professional malware removal service such as Sucuri or Wordfence can clean an infected site, though this is more time-consuming and expensive than a backup restoration. This is a strong argument for ensuring current backups exist before an incident occurs rather than after.

Is managed WordPress hosting worth the extra cost for security?

For most business websites, yes. Managed WordPress hosting providers include server-level security hardening, automatic core updates, malware scanning, and, in many cases, guaranteed malware removal as part of their offering. The additional monthly cost, typically twenty to fifty pounds more than equivalent shared hosting, is modest relative to the cost of recovering from a security incident or the reputational damage of a compromised site.

How do I know if my WordPress site has been hacked?

Common signs include the site loading noticeably more slowly than usual, unexpected content appearing on pages, visitors being redirected to other websites, Google Search Console showing security warnings, your hosting provider sending security alerts, or antivirus software flagging the site as unsafe. A security plugin with regular malware scanning provides earlier and more reliable detection than waiting for visible symptoms. Running a scan through Sucuri’s free site check at sitecheck.sucuri.net is a quick way to check a site that is not currently running a security plugin.
