Really Simple SSL pro

Really Simple SSL pro contains an extensive scan for mixed content issues, access to premium support, HTTP Strict Transport Security and more!

• Extensive scan which enables you to detect the source of mixed content that couldn’t be fixed automatically, with fix button
• Premium email support (details)
• HttpOnly and secure flags to make the cookies more secure
• Improve security by enabling HTTP Strict Transport Security for your site
• Submit your site to the HSTS preload list
• Warning by email and in your SSL dashboard when your certificate is about to expire
• Mixed content fixer for the back-end
• Easy implementable security headers: X-Content-Type-Options, X-XSS-Protection, X-Frame-Options, Expect-CT, Certificate Transparency, No Referrer When Downgrade header, Content Security Policy. Read the security headers article for more info

The scan works also when your site is still on http, so you can check for issues before you activate SSL!

The scan checks your theme files, plugin files and database for references to stylesheets and javascript libraries with http:// links, or resources (like images on http domains) that would be blocked over SSL. This scan is built to detect these kind of mixed content even when you’re not on SSL yet. Each result has fix button, or if automatic fix is not possible, instructions how to fix it. To read more about the kinds of mixed content the scan searches for, you can read this article.
