WordPress security: How to check if a WordPress plugin is safe

WordPress plugins are invaluable tools for enhancing the functionality and features of your website. With thousands of plugins available in the WordPress repository and third-party marketplaces, it’s essential to exercise caution when selecting and installing plugins to avoid security vulnerabilities, performance issues, and compatibility conflicts. In this comprehensive guide, we’ll explore the best practices and techniques for checking if a WordPress plugin is safe, empowering you to make informed decisions and safeguard your website against potential risks.

Research and due diligence

Before installing any WordPress plugin, it’s crucial to conduct thorough research and due diligence to assess its safety, reliability, and reputation. Start by reading user reviews, ratings, and feedback on the WordPress plugin repository, as well as reputable third-party review sites and forums. Look for patterns of positive or negative experiences, paying attention to comments related to security, performance, and compatibility issues.

Check plugin details and updates

Review the plugin details and information provided on its WordPress repository page, including the developer’s name, description, version history, and last updated date. A reputable plugin developer will regularly update their plugin to address security vulnerabilities, bug fixes, and compatibility issues with the latest WordPress versions. Be wary of plugins that haven’t been updated in a long time, as they may pose a higher risk of security exploits or compatibility issues.

Verify developer reputation and credentials

Evaluate the reputation and credentials of the plugin developer or company behind the plugin. Look for established developers with a track record of creating high-quality, secure plugins that adhere to WordPress coding standards and best practices. Check the developer’s website, portfolio, and social media profiles to learn more about their expertise, experience, and commitment to plugin maintenance and support.

Review plugin code and documentation

For more advanced users or developers, reviewing the plugin’s code and documentation can provide insights into its quality, security practices, and adherence to coding standards. Look for well-documented code with clear comments, proper error handling, and adherence to WordPress coding standards and security best practices. Avoid plugins with obfuscated or encrypted code, as they may conceal malicious intent or vulnerabilities.

Check for security vulnerabilities

Utilize reputable security tools and services to scan plugins for known security vulnerabilities and malware. WordPress security plugins like Wordfence, Sucuri, and iThemes Security offer scanning and monitoring features to detect and mitigate security threats in real-time. Additionally, subscribe to security mailing lists, forums, and blogs to stay informed about emerging security vulnerabilities and patches for popular WordPress plugins.

Assess plugin permissions and access

Review the permissions and access levels required by the plugin to function properly. Be cautious of plugins that request excessive permissions or access to sensitive areas of your WordPress site, such as user data, files, or database tables. Limit plugin permissions to the minimum necessary for its intended functionality, and avoid plugins that request permissions beyond their scope or purpose.

Test plugin compatibility and performance

Before installing a plugin on your live website, test it in a staging environment to assess its compatibility and performance impact. Activate the plugin and test its functionality alongside your existing plugins and themes to identify any conflicts or issues. Monitor website performance metrics such as page load times, server resource usage, and error logs to ensure that the plugin doesn’t degrade site performance or stability.

Backup your website

Before installing any new plugin, it’s essential to perform a full backup of your website to safeguard against potential data loss or site downtime. Use a reliable WordPress backup solution to create backups of your files, database, and media library, ensuring that you can restore your site to a previous state if any issues arise during the plugin installation or activation process.

Stay informed and updated

Stay informed about the latest WordPress security news, trends, and best practices to proactively protect your website against security threats and vulnerabilities. Subscribe to reputable WordPress blogs, security newsletters, and forums to receive timely updates and recommendations for securing your WordPress site. Additionally, enable automatic updates for WordPress core, themes, and plugins to ensure that you receive security patches and bug fixes promptly.

Monitor plugin activity and support

After installing a plugin, monitor its activity and performance regularly to ensure that it continues to meet your expectations and doesn’t introduce any new security risks or issues. Keep an eye on the plugin’s support forum or ticketing system for updates, bug reports, and security advisories from the developer. If you encounter any issues or concerns, reach out to the plugin developer for assistance or consider seeking alternatives if necessary.
