In this article, we’ll show you how to spot and secure any unknown devices hitching a ride on your network. 🕵️‍♂️✨ And don’t stress—we’re keeping it free of tech-speak and super simple to follow, even if you’re not a tech guru!

How to Identify and Secure Unknown Devices

Just finished a Trend Micro Home Network Security scan and found some mystery devices connected to your network? No worries! Let’s dive into how you can keep your network safe and secure.

Step 1: List Your Device MAC Addresses

Each gadget on your network has a unique tag known as a MAC address. Whether you’re using an Android, iPhone, iPad, Windows PC, or Mac, here’s how you can find it:

1. Android Phone/Tablet:

  • Open the Settings app.
  • Go to About Phone or About Device.
  • Tap on Status or Hardware Information.
  • Scroll to find your Wi-Fi MAC address.

2. iPhone/iPad:

  • Open Settings.
  • Head to General and then About.
  • Your Wi-Fi Address (MAC) is right there.

3. Windows PC:

  • Go into your network settings.
  • Whether you’re using Wi-Fi or Ethernet, select your connection.
  • Scroll to find the Physical Address (MAC).

4. Mac:

  • Click on System Preferences.
  • Go to Network, select your network, then click Advanced.
  • The Wi-Fi Address (MAC) will be listed.

By keeping track of these MAC addresses, you’ll be better equipped to spot any intruders on your network. 🕵️‍♂️

Step 2: Check for Matches

Now it’s time to match the MAC addresses you’ve noted with the devices listed in your Trend Micro Home Network Security app. Here’s how to do it:

  • Open the Trend Micro Home Network Security app.
  • Tap on the Menu icon.
  • Select Devices and choose the device you want to check.
  • Look for the MAC ID in the app.
  • Compare this MAC ID to the ones you’ve recorded to see if there’s a match.

This step will help you confirm whether all devices on your network are known and authorized. 👍

Trend Micro Recommends Removing Unknown Devices

To safeguard your home network, follow these essential steps:

  • Scan Your Network: Regularly check for any unfamiliar devices.
  • Update Your Wi-Fi SSID: Change the default name of your Wi-Fi to something unique.
  • Strengthen Your Wi-Fi Password: Make sure your password is strong and hard to guess. 🛡️
  • Enable New Device Approval: Require approval for any new device trying to connect.
  • Disable WPS: Turn off Wi-Fi Protected Setup in your router’s admin console to enhance security.

Your home network security is crucial, and we’re here to help you keep it safe and sound. Remember, taking these steps can significantly reduce the risk of unauthorized access.


Securing your home network doesn’t have to be a daunting task. By following these simple steps—from identifying all devices connected to your network to implementing stronger security measures—you can create a safer digital environment for you and your family. 🏠✨

  • List all device MAC addresses to recognize each device connected to your network.
  • Verify device matches using the Trend Micro Home Network Security app to ensure all devices are known and authorized.
  • Implement recommended security enhancements such as updating your SSID, strengthening your password, enabling new device approval, and disabling WPS to fortify your network against unwanted intrusions.

Remember, a secure network is a strong foundation for your digital peace of mind. Stay vigilant and keep your network health in check to defend against potential threats. With these tips, you’re well on your way to maintaining a secure and robust home network. 🛡️


What is a MAC address and why is it important?

A MAC address is a unique identifier assigned to each device on a network. Knowing the MAC addresses of your devices helps you identify and manage which devices are allowed to connect to your network, ensuring that only authorized devices have access.

How do I find the MAC address of my devices?

You can find the MAC address on various devices by navigating through their settings. For example, on Android devices, it’s typically found under Settings > About Phone > Status. On iPhones, it’s under Settings > General > About.

What should I do if I find an unknown device on my network?

If you identify a device that doesn’t match any known MAC addresses of your devices, you should consider removing it from your network to prevent potential security risks. This can be done through your network security app or router settings.

Why should I change my default Wi-Fi SSID?

Changing your default Wi-Fi SSID (the name of your Wi-Fi network) helps protect against unauthorized access, as it makes it less obvious which network is yours, especially if the default name includes the brand which could be targeted by hackers.

What are the benefits of enabling New Device Approval?

Enabling New Device Approval adds an extra layer of security by requiring your permission before a new device can connect to your network. This prevents unauthorized devices from accessing your network without your knowledge.

Why is it recommended to disable WPS on my router?

Disabling WPS (Wi-Fi Protected Setup) is recommended because it can be a security vulnerability. WPS is designed to make it easier to connect devices to your network, but it can also allow intruders to connect easily if they exploit this feature.
