Really Simple SSL Pro

Really Simple SSL Pro is an essential WordPress security extension built to automate SSL certificate migration and site-wide security hardening. It automatically configures server environments to run securely over HTTPS, resolving mixed content warnings, updating insecure URLs in the database, and issuing HTTP strict transport security (HSTS) headers. Beyond basic SSL activation, the Pro version offers advanced security features including HTTP Security Headers configuration (Content Security Policy, Permissions Policy, X-Frame-Options), vulnerability scanning for core/plugins/themes, real-time security alerts, and automated mixed content fixer algorithms. It provides a simple, one-click solution to keep sites secure, compliant with search engine HTTPS standards, and safe from common web vulnerabilities.

Main Features

• Automatic SSL configuration & HTTPS redirect — Detects existing SSL certificates and automatically redirects all HTTP traffic to secure HTTPS via 301 redirects and server rules.
• Automatic mixed content fixer — Identifies and resolves insecure HTTP resource calls (images, scripts, stylesheets) dynamically on both the front end and back end.
• Advanced HTTP Security Headers — Easily configure essential security headers including Content Security Policy (CSP), HSTS (HTTP Strict Transport Security), X-Content-Type-Options, X-Frame-Options, and Referrer-Policy.
• Vulnerabilities scanner & patch alerts — Continuously monitors installed WordPress core, plugins, and active themes against known security databases and alerts administrators to open vulnerabilities.
• Database URL & link fixer — Scans and updates legacy http:// internal links, database entries, and external embeds to https:// permanently.
• WordPress site hardening controls — Toggle security measures such as disabling file editing, turning off directory browsing, restricting REST API endpoints, and hardening user permissions.
• Two-Factor Authentication (2FA) — Add multi-factor authentication requirements for user logins (compatible with Google Authenticator and email verification codes).
• SSL certificate health monitor — Monitors certificate expiration dates, SSL chain validity, and domain name matching to prevent unexpected HTTPS downtime.

Benefits

• Saves technical configuration time — Eliminates the need to manually edit .htaccess files, wp-config.php, or run complex database search-and-replace scripts.
• Boosts search engine rankings & trust — Enforces secure HTTPS connections, directly aligning with search engine security mandates and building visitor confidence.
• Eliminates browser security warnings — Fixes mixed content issues to prevent browsers from displaying "Not Secure" flags or blocking insecure assets.
• Comprehensive website hardening — Strengthens overall WordPress security posture through automated security headers, vulnerability monitoring, and 2FA logins.
• Lightweight & fast performance — Runs efficiently with minimal database footprint, ensuring server response times remain fast.

Who is it suitable for?

• WordPress site owners & bloggers needing a seamless, one-click transition from HTTP to secure HTTPS.
• E-commerce & WooCommerce stores requiring strict HTTPS encryption, security headers, and PCI-DSS compliance for customer transaction security.
• Agencies & web developers managing client portfolios who want an efficient automated security hardening tool across multiple sites.
• Non-technical site administrators looking to fix mixed content warnings and secure site logins without manual coding.
• Security-conscious organizations needing continuous vulnerability detection, security header management, and SSL renewal monitoring.
