To install a part of the suite on a new device, you click "Add device" and then enter an email address. A setup link is then sent to the device that, when clicked, sends you to a Web page where you can download the software. In the case of Android, you can also scan a QR code that appears onscreen and download the software that way.
Apart from installing software, though, there's little else you can do on the Web dashboard. It shows you when a device is using a part of the suite -- for example, when a PC is actively using Norton 360, the dashboard will say that it's "online." But just showing that a device is using a product isn't a particularly useful feature. And it doesn't always work -- it never, for example, showed when my Android phone was using Norton Mobile Security.
Those not already familiar with Symantec's Windows-based suite Norton 360 will find an excellent security suite that includes extras for juicing up system performance and backing up files. You'll find all the usual security tools, including anti-virus, anti-malware, anti-spam and firewall; there is also identity protection, which includes anti-phishing, malicious Web-page blocking and password management. It's unlikely you'll need to change any default settings, but if you want to, the Settings area lets you tweak to your heart's content.
Particularly noteworthy is Norton's System Insight feature, which checks any currently running software for safety and reliability. It does this by leveraging the experience that Symantec product users have had with the application, and shows the application's relative trustworthiness, rating it either Poor, Good or Trusted. System Insight also shows whether that rating is based on input from a few people or many. And it shows a rating for each application's stability level, also based on other people's usage.

System Insight also warns you if any of these applications are slowing down your system. Stability and trust ratings are shown in a list side by side with resource usage, so it's easy to see at a glance how each app rates.
Norton 360 also includes a solid set of tools for improving PC performance, such as a disk optimizer and file cleanup. Especially useful is Startup Manager, which provides details about each application and helps you decide which to run (and which not to run) at startup, so that you can speed your bootup and possibly improve overall performance. You can also delay applications from starting until some time after startup. And it includes Parental Controls as well.
