Easily improve site security with WordPress Hardening, Two-Factor Authentication (2FA), Login Protection, Vulnerability Detection and SSL certificate.
Really Simple Security is the most lightweight and easy-to-use security plugin for WordPress. It secures your WordPress website with SSL certificate generation, including proper 301 https redirection and SSL enforcement, scanning for possible vulnerabilities, Login Protection and implementing essential WordPress hardening features.
We believe that security should have the absolute minimum effect on website performance, user experience and maintainability. Therefore, Really Simple Security is:
Migrates your website to HTTPS and enforces SSL in just one click.
Tweak your configuration and keep WordPress fortified and safe by tackling potential weaknesses.
Get notified when plugins, themes or WP core contain vulnerabilities and need appropriate action.
Allow or enforce Two-Factor Authentication (2FA) for specific user roles. Users receive a two-factor code via Email.
Protect your site with all essential security features by upgrading to Really Simple Security Pro.
Really Simple Security Pro includes a performant and efficient WordPress firewall, to stop bots, crawlers and bad actors with IP and username blocks.
Security headers protect your site visitors against the risk of clickjacking, cross-site-forgery attacks, stealing login credentials and malware.
When a vulnerability is detected in a plugin, theme or WordPress core you will get notified accordingly. With Vulnerability Measures, you can configure simple but effective measures to make sure that a critical vulnerability won’t remain unattended.
Secure your website’s login process and user accounts with powerful security measures.
With Limit Login Attempts you can configure a threshold to temporarily or permanently block IP addresses or (non-existing) usernames. You can also throw a CAPTCHA after a failed login (hCaptcha or Google reCaptcha)
If you want to support the continuing development of this plugin, please consider buying Really Simple Security Pro, which includes some excellent security features and premium support.
Our mission is to make complex WordPress requirements really easy. Really Simple Security is developed by Really Simple Plugins.
For generating SSL certificates, Really Simple Security uses the le acme2 PHP Let’s Encrypt client library, thanks to ‘fbett’ for providing it. Vulnerability Detection uses WP Vulnerability, an open-source initiative by Javier Casares. Want to join as a collaborator? We’re on GitHub as well!

All features that made Really Simple SSL the most powerful and easy-to-use SSL generation and redirect plugin are still part of Really Simple Security. The plugin is developed with a modular approach: if you don’t want to use the full set of security features, the unused code will not be loaded and won’t have any effect on your site’s performance.
In our experience, security solutions for WordPress are often hard to configure, trigger many false positives and have a significant impact on site performance. We have been receiving requests from our users to simplify WordPress security for years, so that has become our mission!
You couldn’t make us happier! Really Simple Security is GPL licensed and co-created by the WordPress community.

We added the possibility to generate a Free SSL Certificate with Let’s Encrypt in our Really Simple Security Wizard. We have an updated list available for all possible integrations here. Please leave feedback about another integration, incorrect information, or you need help.
If you are experiencing redirect loops on your site, try these instructions. This can sometimes happen during the migration to HTTPS or due to conflicting redirect rules.
Yes. There is a dedicated network settings page where you can control settings for your entire network, at once.
Under Login Protection, you can configure minimum strength settings and require users to change their passwords after a defined interval. Disabling weak password usage is a best practice.
You can set a custom login URL under Advanced Site Hardening, which helps prevent brute force login attacks and bots targeting wp-login.php.
Yes. The plugin enforces HTTPS and handles all necessary redirects, optionally using .htaccess or PHP.
Really Simple Security and WordFence greatly overlap in term of functionality. If you like to use specific features from both plugins, we strongly recommend not to enable similar features twice. The benefit of Really Simple Security is that disabled features don’t load any code, so won’t have an impact on site performance.
