Is there an automated "security as a service" service that if I subscribed to it, it would have told me that this is a problem on my websites? It really annoys me randomly hearing about critical security issues through tech news websites - there should be a more systematic way for "non-security professionals" to ensure their sites are protected to best practice levels.
