Really Simple Security – Simple and Performant Security (formerly Really Simple SSL)

Description

Easily improve site security with WordPress Hardening, Two-Factor Authentication (2FA), Login Protection, Vulnerability Detection and SSL certificate.

Really simple, Effective and Performant WordPress Security

Really Simple Security is the most lightweight and easy-to-use security plugin for WordPress. It secures your WordPress website with SSL certificate generation, properly enforcing en redirecting to https, 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:

• Lightweight: Every security feature is developed with a modular approach and with performance in mind. Disabled features won’t load any redundant code.
• Easy-to-use: 1-minute configuration with short onboarding setup.

Security Features

Easy SSL Migration

Migrates your website to HTTPS and enforces SSL in just one click.

• 301 redirect via PHP or .htaccess
• Secure cookies
• Let’s Encrypt: Install an SSL Certificate if your hosting provider supports manual installation.
• Server Health Check: Your server configuration is every bit as important for your website security.

WordPress Hardening

Tweak your configuration and keep WordPress fortified and safe by tackling potential weaknesses.

• Prevent code execution in the uploads folder
• Prevent login feedback and disable user enumeration
• Disable XML-RPC
• Disable directory browsing
• Username restrictions (block ‘admin’ and public names)
• and much more..

Vulnerability Detection

Get notified when plugins, themes or WP core contain vulnerabilities and need appropriate action.

Login Protection

Allow or enforce Two-Factor Authentication (2FA) for specific user roles. Users receive a two-factor code via Email.

Improve Security with Really Simple Security Pro

Protect your site with all essential security features by upgrading to Really Simple Security Pro.

Advanced SSL enforcement

• Mixed Content Scan & Fixer. Detect files that are requested over HTTP and fix it, both Front- and Back-end.
• Enable HTTP Strict Transport Security and configure your site for the HSTS Preload list.

Firewall

Really Simple Security Pro includes a performant and efficient WordPress firewall, to stop bots, crawlers and bad actors with IP and username blocks.

• 404 blocking – Blocks crawlers as they trigger unusual numbers of 404 errors.
• Region blocking – Only allow/block access to your site from specific regions.
• Automated and customisable Firewall rules.
• IP blocklist and allowlist.

Security Headers

Security headers protect your site visitors against the risk of clickjacking, cross-site-forgery attacks, stealing login credentials and malware.

• Independent of your Server Configuration, works on Apache, LiteSpeed, NGINX, etc.
• Protect your website visitors with X-XSS Protection, X-Content-Type-Options, X-Frame-Options, a Referrer Policy and CORS headers.
• Automatically generate your WordPress-tailored Content Security Policy.

Vulnerability Measures

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.

• Force update: An update process will be tried multiple times until it can be assumed development of a theme or plugin is abandoned. You will be notified during these steps.
• Quarantine: When a plugin or theme can’t be updated to solve a vulnerability, Really Simple Security can quarantine the plugin.

Advanced Site Hardening

• Choose a custom login URL
• Automated File Permissions check and fixer
• Rename and randomize your database prefix
• Change the debug.log file location to a non-public folder
• Disable application passwords
• Control admin creation
• Disable HTTP methods, reducing HTTP requests

Login Protection

Secure your website’s login process and user accounts with powerful security measures.

• Two-Step verification (Email login)
• Enforce strong passwords and frequent password change
• Limit Login Attempts

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)

Access Control

• Restrict access to your site for specific regions.
• Add specific IP addresses or IP ranges to the Blocklist or Allowlist.

FAQ

Knowledge Base

For more detailed explanations and documentation on all Really Simple Security features, please search the Knowledge Base

What happened with Really Simple SSL?

All features that made Really Simple SSL the most powerful and easy-to-use SSL 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.

Why Really Simple Security?

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!

I want to share my feedback or contribute to Really Simple Security

You couldn’t make us happier! Really Simple Security is GPL licensed and co-created by the WordPress community. All feedback is highly appreciated and has always helped us to better understand users’ needs. For code contributions or suggestions, we’re on GitHub. For suggestions, please open a support ticket You can also express your appreciation by leaving a review.

Mixed Content issues

Most mixed content issues are caused by URLs in CSS or JS files. For detailed instructions on how to find mixed content read this article.

Generating a Let’s Encrypt SSL Certificate

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.

Redirect loop issues

If you are experiencing redirect loops on your site, try these instructions.

Is the plugin multisite compatible?

Yes. There is a dedicated network settings page where you can control settings for your entire network, at once.

Uninstalling Really Simple Security

The plugin checks your certificate before enabling, but if, for example, you migrated the site to a non-SSL environment, you might get locked out of the back-end.

If you can’t deactivate, do not just remove the plugin folder to uninstall! Follow these instructions instead.

Reviews

Excelente plugin.

Ya no es necesario preocuparme más por la seguridad de mi sitio web.

Forces you to enable internal options (Firewall,Limited Login Attempts)

manni65929 October 20, 2024 1 reply

By now developers have become aware that you can use the healthscreen to nagg users with “critical” issue that turn out to be covered by a different plugin or aren’t neccessarry at all. This plugin naggs you to enable their Firewall and their “Limited Login Attempts”. In my case, both are handled with Wordfence wich works pretty well. If the authors of this plugin want me to end my subcription, then please continue. Otherwise remove the nagg from the health screen or you plugin will be reported.

Funciona bien y es fácil de usar

Easy to Use

Really Simple and easy to use and Secure website. Its great!

Immensely valuable security plug-in

magdamunro October 11, 2024 1 reply

This is one of the self-evident plug-ins to pay for in my arsenal of tools. Not only does it help with setting up a secure connection, it also gives very useful security suggestions, scans for vulnerabilities in the installations and other plug-ins. During 3+ years of use I’ve had one single serious problem after an update, that made me have to reinstall, some minor things helped with great support. It’s easy to say, that for me using this product on at least two sites has been very positive. Usually I complain a lot, not with this.Check out also the other offerings from the same company, like Burst and Complianz. Totally professional products.

Très bon plugin
