Really Simple SSL Pro – WordPress Plugin Full Review

Securing your WordPress website is no longer optional — it’s essential. With increasing cyber threats, Google’s SEO preference for HTTPS, and modern browser warnings about “insecure websites,” adding an SSL certificate is just the beginning. What comes next is ensuring your entire site runs smoothly under HTTPS, without breaking links, images, or functionality. That’s where the Really Simple SSL Pro WordPress Plugin shines.

While the free version already helps switch your site to HTTPS with minimal effort, Really Simple SSL Pro WordPress Plugin adds powerful features for advanced security, mixed content detection, hardening headers, and GDPR compliance.

In this comprehensive review, we’ll break down the core features, benefits, use cases, pricing, and whether Really Simple SSL Pro WordPress Plugin is worth it for your WordPress site.

What is Really Simple SSL Pro?

Really Simple SSL Pro WordPress Plugin is a premium WordPress plugin developed by Really Simple Plugins. It enhances the core functionality of the free Really Simple SSL plugin — which forces your site to use HTTPS — by adding advanced features like:

• Mixed content scanner and fixer

• Security headers (HSTS, Content Security Policy, X-Frame-Options, etc.)

• Server Health checks

• HTTP Strict Transport Security (HSTS) preload support

• GDPR privacy enhancements

• Multi-site SSL management

• Premium support and diagnostics

The goal? To make your website more secure, privacy-compliant, and professionally configured — without requiring deep technical expertise.

Key Features of Really Simple SSL Pro

Let’s walk through the standout features that make this plugin a complete SSL and security toolkit for WordPress users.

1. Mixed Content Fixer & Scanner

After switching to HTTPS, many sites suffer from “mixed content” issues — where some images, scripts, or stylesheets still load over HTTP. This triggers browser warnings and breaks secure padlocks.

Really Simple SSL Pro WordPress Plugin includes:

• Mixed Content Scanner: Detects all insecure links across your site

• Auto Fixer: Replaces HTTP URLs with HTTPS versions

• Manual Fix Suggestions: For harder-to-fix content (e.g., external scripts)

This ensures your padlock stays green and your site is fully secure.

2. Advanced Security Headers

Modern web security relies heavily on HTTP headers. Really Simple SSL Pro WordPress Plugin lets you configure:

• HSTS (HTTP Strict Transport Security): Enforces HTTPS permanently

• X-Content-Type-Options: Prevents MIME-type sniffing

• X-Frame-Options: Blocks clickjacking via iframes

• X-XSS-Protection: Mitigates XSS attacks

• Content Security Policy (CSP): Controls which content sources are allowed

• Referrer Policy: Controls how much referral information browsers pass

All headers are toggleable from the UI, with helpful explanations and recommendations.

3. HSTS Preload & Redirect Settings

HSTS preload lets your domain be included in browser preload lists, meaning it will only ever load over HTTPS — even if users manually type http://.

The plugin simplifies:

• Adding HSTS preload headers

• Redirecting all HTTP requests to HTTPS

• Testing HSTS header validity before submitting to preload lists

4. Security Monitoring & Site Health

Really Simple SSL Pro WordPress Plugin includes a Site Health Security Dashboard, offering insights into:

• SSL certificate validity and expiration

• Server configuration status

• PHP and WordPress version compatibility

• Recommended hardening steps

This helps maintain long-term site security and performance.

5. GDPR & Privacy Enhancements

The plugin supports privacy-focused features like:

• Enabling referrer stripping to avoid leaking user browsing data

• Limiting access to REST API and XML-RPC endpoints

• Blocking HTTP requests to known trackers or unsafe domains

These features support GDPR and other privacy regulation compliance efforts.

6. Full Multisite Network Support

For WordPress multisite users, Really Simple SSL Pro WordPress Plugin provides:

• Network-wide SSL activation

• Individual site overrides

• Centralized configuration and monitoring

This makes SSL management efficient and consistent across large site networks.

7. Email Notifications & Alerts

Get notified when:

• Your SSL certificate is about to expire

• Insecure content is detected

• Important security changes are needed

These proactive alerts help prevent site downtime or SEO penalties due to expired or broken SSL configurations.

8. Professional Support

As a Pro user, you gain access to:

• Priority email support

• Expert help with server-specific configurations (Apache, NGINX, etc.)

• Assistance with HSTS, CSP, and mixed content resolution

What’s the Difference Between the Free & Pro Versions?

The free version of Really Simple SSL:

• Forces HTTPS by enabling WordPress’s internal rewrite rules

• Automatically redirects HTTP to HTTPS

• Handles basic mixed content via output buffering

• Offers basic SSL status insights

The Pro version adds:

• Mixed content scanning & advanced fixer

• Security headers configuration

• HSTS preload support

• Server health diagnostics

• Multisite management

• GDPR-friendly privacy tools

• Premium support

For basic blogs, the free version may suffice. But for any business, eCommerce, or high-traffic site, the Pro version adds essential protection layers.

Use Cases for Really Simple SSL Pro

Here are real-world examples of where this plugin delivers huge value:

1. Business Websites Moving to HTTPS

Easily transition from HTTP to HTTPS without breaking existing content or functionality. Fix mixed content and maintain SEO rankings.

2. WooCommerce Stores

Ensure your store’s checkout, product pages, and forms remain fully secure and compliant with PCI standards.

3. Membership & LMS Sites

Protect login areas, user accounts, and payment gateways. Block insecure elements and enforce user data privacy.

4. Bloggers & Content Creators

Fix broken padlocks due to embedded media or external scripts. Configure basic security headers without editing .htaccess or NGINX configs.

5. Digital Agencies

Manage SSL across multiple client sites, apply security headers, and ensure best practices with minimal effort.

6. Multisite Networks

Enforce HTTPS across dozens or hundreds of subsites from a centralized dashboard with network-wide policies.

Benefits of Using Really Simple SSL Pro

Let’s summarize the biggest benefits of using this plugin:

1. Fast SSL Setup & Maintenance

No coding required. The plugin does the heavy lifting—detecting issues, rewriting URLs, and configuring settings for you.

2. Stronger Site Security

Security headers and HSTS reduce exposure to man-in-the-middle (MITM) attacks, content hijacking, and injection vulnerabilities.

3. Improved SEO & Trust

HTTPS is a Google ranking signal. A green padlock also builds user trust and lowers bounce rates.

4. Simplified GDPR Compliance

Block referrer leaks, limit data exposure, and reduce reliance on tracking scripts for greater user privacy.

5. Prevention of Browser Warnings

Avoid Chrome’s “Not Secure” warnings by ensuring full site HTTPS and resolving any content conflicts.

6. Ongoing Monitoring & Alerts

Proactive issue detection and expiration notifications help prevent disruptions before they impact users or rankings.

Limitations & Considerations

While Really Simple SSL Pro WordPress Plugin is powerful, it’s important to understand what it doesn’t do:

• It doesn’t issue SSL certificates. You’ll still need to obtain and install an SSL certificate (via Let’s Encrypt, Cloudflare, or your host).

• Limited firewall protection. It’s not a full security suite like Wordfence or Sucuri — it focuses specifically on SSL and headers.

• External CDN content needs manual review. If you embed resources from insecure external URLs, you may need to update or replace them yourself.

Still, for managing SSL transitions and enforcing best practices, the plugin is unmatched in simplicity and reliability.

Pricing of Really Simple SSL Pro

The plugin is available in the following annual pricing tiers:

• 1 Site License: $39/year

• 5 Sites License: $69/year

• Unlimited Sites License: $159/year

Each license includes:

• 1 year of premium updates and support

• Full access to all Pro features

• Priority technical assistance

A 14-day money-back guarantee ensures you can try it risk-free.

Alternatives to Really Simple SSL Pro

Here are a few comparable options:

1. WP Force SSL Pro

Offers SSL redirection, mixed content fixer, and HTTPS monitoring — but lacks header configuration or privacy controls.

2. SSL Zen

Assists with SSL certificate installation and HTTPS redirection but is more limited on mixed content and security hardening.

3. Manual Configuration (for Developers)

For advanced users, manually editing .htaccess, wp-config.php, or server config files is possible — but error-prone and time-consuming.

4. Full Security Suites (Wordfence, iThemes Security)

Broader plugins that offer firewalls, login protection, etc., but don’t specialize in SSL migration or mixed content scanning like Really Simple SSL Pro.

For dedicated SSL and HTTPS configuration, Really Simple SSL Pro is in a league of its own.

Is Really Simple SSL Pro Worth It?

If you run:

• A business, eCommerce, or professional WordPress site

• A multisite network with various domains

• A privacy-focused or security-conscious brand

…then Yes — Really Simple SSL Pro is absolutely worth it.

You’ll benefit from:

• Cleaner, secure content without mixed elements

• Stronger protection with security headers

• Easy-to-manage HSTS and preload settings

• Improved compliance and trustworthiness

• Peace of mind with monitoring and premium support

For just a few dollars per month, the plugin secures your reputation, protects your visitors, and eliminates SSL headaches.
