Free open-source CMS platforms like WordPress, Joomla, and Drupal power millions of websites — but their open code and slow update cycles make them prime targets for hackers. Learn how to protect your free CMS with enterprise-grade security monitoring and malware removal.
Of all websites worldwide are built on WordPress alone
Of WordPress installations are vulnerable to known security exploits
Websites hacked each year due to CMS vulnerabilities and outdated plugins
Average update frequency for many free CMS core systems
Today, free CMS (Content Management System) platforms are the most popular on the web. Among them, it is worth mentioning WordPress, Joomla, and Drupal — these are absolute leaders by the number of websites built on these website management systems. These CMS platforms work perfectly on websites of any complexity, from personal blogs to large enterprise e-commerce stores, and because of their massive adoption, they have become the primary target of hacking attacks, malware injections, and unauthorized access attempts.
The main difference between such free CMS platforms and commercial ones is that they have an open-source code — which means it is significantly easier for attackers to find vulnerabilities and soft spots in the codebase. Hackers actively study the publicly available source code to identify security flaws and successfully exploit these opportunities to compromise millions of websites simultaneously.
Free CMS platforms are updated much less frequently than commercial ones. This is because the web developers who maintain these systems often work on a voluntary basis and frequently do not hurry to issue new versions of modules and plugins. Consider how often you receive messages notifying you about new versions of the operating system you use — most of these updates are aimed at eliminating vulnerabilities in the code. However, many free CMS platforms are updated only twice a year or even less frequently, leaving known security holes open for months.
It is also necessary to note that apart from the CMS core itself, you use modules and plugins developed by third-party producers, which undoubtedly makes your website even more vulnerable. You never know how many mistakes a developer has made in the code — and one single mistake is enough for an attacker to gain administrator access to your website. You can find out about the devastating consequences of a compromised admin panel in our article Protection of Your Website.
Visit the official WordPress website or that of any other free CMS and find out how many critical security updates have been issued during the last year. Then multiply this figure by 10,000 and you will get an approximation of the number of websites hacked during that same period. These are not thousands but millions of compromised websites. Your website is essentially like a personal computer, and the installed CMS is like its operating system. Now remember how often viruses and malware appear seemingly from nowhere — and even the latest updates and antivirus software fail to fully protect you, because it is only a highly qualified specialist with unique security software who can truly ensure your website's safety.
Such professional security software will not only prevent attacks on your websites but will also notify you about suspicious activity on your server in real time. Our specialists react promptly to every threat and take immediate action to render all attacks futile — providing true enterprise website security for businesses of any size.
The difference between a vulnerable open-source CMS installation and one secured by SiteGuarding's advanced web protection is the difference between an open door and a fortified vault.
Understanding the specific threats that target open-source CMS platforms helps you appreciate the critical importance of professional security monitoring and advanced web protection.
Attackers exploit known CMS vulnerabilities to inject malicious code — redirects, backdoors, crypto miners, and spam — into your website files and database, compromising your visitors and business reputation.
Automated bots target default login pages (wp-admin, administrator) with thousands of password combinations per minute. Without protection, even moderately strong passwords can eventually be cracked.
Poorly coded plugins and outdated CMS core files allow attackers to inject malicious SQL queries into your database, stealing customer data, admin credentials, and sensitive business information.
Once hackers find a vulnerability, they install hidden backdoors and webshells that provide persistent access to your server — even after you update your CMS or change passwords.
Attackers inject hidden links, pharma spam, and Japanese keyword hacks into compromised CMS sites, triggering Google blacklisting and destroying your search rankings and organic traffic overnight.
Third-party plugins and themes — the backbone of any free CMS — contain the vast majority of security vulnerabilities. One outdated or poorly coded plugin can expose your entire website to attack.
Your CMS-powered website deserves the same level of security monitoring and malware protection as enterprise-grade systems. SiteGuarding makes professional website security affordable and accessible.

Common questions about free CMS security, open-source vulnerabilities, and how SiteGuarding protects WordPress, Joomla, and Drupal websites.
Free CMS platforms have open-source code that anyone — including hackers — can study to find vulnerabilities. Additionally, they rely heavily on volunteer developers, which often means slower security patches and less frequent core updates compared to commercial systems with dedicated paid security teams.
WordPress can be safe when properly secured. However, a default WordPress installation without professional security measures is highly vulnerable. With SiteGuarding's protection — including 24/7 monitoring, WAF, malware scanning, and expert support — WordPress becomes a secure platform suitable for business and enterprise use.
You should check for and apply updates at least once every 1–2 weeks. Security patches should be applied immediately upon release — ideally within 24 hours. SiteGuarding's monitoring tools alert you when critical updates are available and can assist with safe update procedures.
