Lumturio offers users and agencies powerful and reliable tools to monitor CMS security. 
As such, our platform empowers you to quickly and efficiently monitor all your 
clients’ websites, allowing you to proactively update them and keep them safe.
This plugin offers a way to collect data from WordPress websites 
to check on modules and versions used, instead of having every site 
check for updates separately.
This allows administrators to build their own monitoring interface to 
check on multiple installations at once.

This plugin removes the WordPress update nag that appears at the top of all admin pages when a new version of WordPress is released.
Tired of WordPress nagging you about a new release? Maybe you already know about it and want to hold off on an update and would rather not see the update nag on every admin page you visit. Activate this plugin and be bothered no more!
The status of your version of WordPress (be it current or out-of-date) is still reflected in the footer of your admin pages and in the update count link in the admin bar.
And certainly, of course, I don’t advocate completely ignoring the fact that updates often contain fixes for critical bugs or exploits. However, there are various other means of learning about updates; and once known, not everyone is able or willing to update immediately.
