Qualys BrowserCheck is a cloud service that scans your browsers and plugins to see if they’re all up-to-date. It’s an “online checkup” that relieves you from having to manually chase the constantly-shifting landscape of patches and updates to determine what you should be using. BrowserCheck identifies which browsers and plugins are used on your computer and whether newer versions have been released by vendors. On PCs running Microsoft Windows XP or later, BrowserCheck can also verify that important OS settings are enabled and Windows security updates are being received.
