BullGuard has a quick and easy tool that can help you find out if there are any basic problems. It’s called the Internet of Things Scanner. The service checks to see if any of your devices are on Shodan, a search engine that lets anyone find IoT devices like cameras, printers and thermostats that are publicly accessible on the internet. Anything that’s publicly accessible may also be vulnerable to hackers if there are any security flaws in the software that can be exploited.

Using BullGuard’s web app is easy – just land on the website and click Check if I am on Shodan. A few seconds later you should have your answer. If all goes well, you’ll see a result like the one above.

Next, you can click Deep Scan to take a look at devices on your network and see if BullGuard’s scanner can find any security issues. The downside, BullGuard warns, is that a deep scan may cause vulnerable devices to be listed on Shodan. But if it does find any problems, BullGuard says it will offer details on how to secure your vulnerable devices.

The company also has an IoT consumer guide with three basic tips for securing your network that anyone should do regardless of whether they have smart devices at home or not: set a password on your smartphone, change the default password for your router’s administration features and change your Wi-Fi network password from the default.

That’s about all there is to BullGuard’s IoT scanner. It’s a simple way to check for any obvious vulnerabilities whenever you add any new devices to your growing collection of smart home devices.

    The scan is seriously flawed, it just appears to be a standard open port scanner. It doesn’t giver you any information other than the ports that are open and doesn’t even understand/explain that some ports have to be open in certain circumstances – eg. port 5060 is necessary for VOiP phones, if you close it off they won’t work…

    If it actually looked at the devices on your internal network and checked open ports/security/firmware issues it might be worthwhile but as it stands it is relatively pointless and most likely just pushing you towards BullGuards own security products which are poorly rated.
