Drupal vs Other CMSs: Security Features Compared

Is Your CMS Secure? A Deep Dive Into Drupal vs Other CMS Platforms

Website security is more critical than ever, with cyberattacks increasing by 300% in recent years. While WordPress, Joomla, and AEM dominate the CMS market, which platform is the safest?

Drupal has long been recognized for its robust security architecture, but how does it compare to its competitors? In this guide, we break down the security strengths and weaknesses of the top CMS platforms, helping you choose the best solution for your business in 2025.

Why Security Matters in CMS Selection

The wrong CMS choice can expose your website to:

• Data breaches and leaked customer information.
• Malware infections leading to search engine blacklisting.
• SQL injections allowing hackers to manipulate databases.
• Brute force attacks compromising administrator credentials.

Understanding the built-in security of different CMS platforms is essential for long-term digital protection.

Drupal: The Enterprise-Grade Security Leader

Drupal is an open-source CMS known for its flexibility, scalability, and high-security standards. It is widely used by governments, NGOs, and large enterprises due to its proactive security measures and a dedicated security team that ensures continuous updates and patches.

Key Drupal Security Features

• Strict Role-Based Access Control (RBAC) – Fine-tuned user permissions ensure only authorized users access critical areas.
• Regular Core & Module Updates – Drupal quickly patches vulnerabilities, reducing exposure time.
• Built-in Database Encryption – Protects sensitive data from being exposed in case of a breach.
• Security-First Development Practices – Codebase undergoes rigorous security audits by experts.
• Protection Against XSS, CSRF & SQL Injection – Prevents common attack vectors that plague many CMS platforms.
• Dedicated Security Team – Actively monitors, audits, and releases security advisories for known vulnerabilities.

Best For: Enterprise websites, government portals, financial institutions, and high-security applications.

Drupal powers over 150+ government websites, including NASA, the European Commission, and the White House, due to its high-security capabilities.

WordPress: The Most Targeted CMS

WordPress powers over 43% of the web, making it the most targeted CMS for cyberattacks. Due to its plugin-heavy ecosystem, security weaknesses are often introduced through outdated or poorly coded third-party extensions.

Key WordPress Security Concerns

• High Plugin Vulnerability Risk – Over 90% of WordPress security breaches are due to insecure plugins.
• Frequent Brute Force Attacks – Weak password protection makes WordPress sites a common target.
• Limited Built-in Security – Most security features require third-party plugins, adding complexity.
• Delayed Patch Rollouts – Updates depend on plugin developers, slowing down fixes for critical issues.

Best For: Small businesses, blogs, and startups with strong security monitoring in place.

Joomla: Flexible but Vulnerable

Joomla offers a balance between WordPress’s ease of use and Drupal’s complexity, but it has struggled with historical security vulnerabilities, including SQL injection risks and unpatched third-party extensions.

Key Joomla Security Features & Issues

• Granular User Permissions – Strong access controls but complex to configure correctly.
• Frequent SQL Injection Exploits – Historically vulnerable to database manipulation attacks.
• Limited Security Ecosystem – Fewer security-focused plugins/modules than Drupal.
• Manual Updates Required – Joomla’s security patches require manual implementation, increasing risk.

Best For: Mid-sized businesses that need flexibility but can handle manual security monitoring.

Adobe Experience Manager (AEM): Secure but Expensive

AEM is a corporate-grade CMS with built-in security features such as data encryption, role-based access, and threat monitoring. However, its high licensing costs and complex setup make it unrealistic for most businesses.

Key AEM Security Features

• Enterprise-Grade Encryption – Protects sensitive data but requires expert configuration.
• Advanced Access Control – Fine-grained permissions for high-security environments.
• Threat Detection & Monitoring – Built-in tools to identify potential cyber threats.
• High Maintenance & Cost – Requires dedicated resources for management and updates.

Best For: Large enterprises with big budgets and dedicated IT teams.

Security Comparison: Drupal vs. Other CMSs

Final Verdict: Which CMS is the Most Secure?

• For enterprise security: Drupal is the strongest choice with its built-in protection against cyber threats and proactive security updates.

• For ease of use but lower security: WordPress is ideal for small businesses, but requires security plugins and constant monitoring.

• For mid-range security needs: Joomla offers flexibility, but has a history of security vulnerabilities.

• For high-budget enterprises: AEM is secure but costly, making it unrealistic for most businesses.

Bottom Line: If security is your top priority, Drupal is the superior CMS.
