Last Updated Apr 19, 2022

Not using secure networks puts your device and your personal information at risk, so it’s always a good idea to know the security that your WIFI puts in place. With the Google Nest becoming more and more popular, you might be wondering if this device is as secure as other WIFI devices. 

Google Nest WIFI uses a firewall and either WPA2 or WPA3 protocol. This makes your WIFI very resistant to cyber-attacks and scammers trying to steal your information. There is also the option to use WPA3 transition mode to make your WIFI more secure. 

You might still be confused about the security of your Google Nest if it’s your first time hearing the words firewall and WPA2 protocol. Don’t worry. We will go over all these things in more detail and show they all work together to give you a secure WIFI network. 

Is Google Nest Firewall Secure?

Everyone who has used a computer before knows about firewalls. They’re supposed to protect us from being hacked and having our personal information stored in said computers stolen. But what you may not know about is WiFi having a firewall. So, is Google Nest firewall secure?

Google Nest has a built-in firewall on the device, so you don’t need to worry about installing it yourself like you need to do on PCs or other devices. A firewall protects your WIFI from making unsolicited connections or connections that you do not authorize. 

It also keeps track of all your connections through two different protocols including the Transmission Control Protocol and the User Datagram Protocol. By keeping track of all communication going through the WIFI network, these protocols can detect unauthorized connections and stop them before they become harmful.

Is Google Nest Firewall Always On?

Keep in mind that there are some settings on the Google Nest that can bypass the firewall. When using these settings, you are allowing your device and network to be more vulnerable. 

Some of these settings that can temporarily shut your Google Nest firewall off include:

  • Port Forwarding is when computers and or certain devices might connect over the internet to other computers and services. It allows you to remotely access items such as when you are accessing files in a backup or when you are using a virtual desktop. 
  • Universal Plug and Play are when your computer, printer, or other device are allowed to discover each other and use the network services to complete a certain task. 

If you don’t think you need to use the above settings, then you don’t have to worry about if the firewall is disabled. However, sometimes these settings are necessary when you are performing a certain task. 

These settings are safe to use even though they disable the firewall because Google Nest also has the WPA2 in place. Just make sure you disable these settings whenever you are not using them so that the firewall can be re-established. 

What Forms of Security Does Google Nest WiFi Have?

If you’re thinking of using Google Nest WiFi and know about how you can be hacked through your WiFi, you may be wondering what kinds of security protocols they have to ensure they will be fully protected.

Let’s take a look at them below.


Google Nest WIFI secures your WIFI network one step further by using either the WPA2 protocol or the WPA3 protocol which is newer than WPA2. When using the WPA3, you will have a network that is more resistant to risks and connections that are trying to through to your network. 

Google Nest WIFI uses the WPA2 by default. More devices are compatible with the WPA2, so not all devices can use the new WPA3. You can turn on the WPA3 transition mode whenever you want by using the Google Home App. 

How to Turn On WPA3 Transition Mode for Google Nest

You might also be curious to know how to turn on WPA3 transition mode so you can use it whenever you want. 

Follow these steps according to Google Support:

  1. Open the Google Home app on your device. 
  2. Tap Wi-Fi. 
  3. Tap the settings wheel at the top right corner. 
  4. Turn on WPA3. 

Keep in mind that any time you toggle WPA3 on or off the network will restart for a few seconds so devices will lose connectivity. 

Automatic Updates Keep Google Nest WiFi Safe

Automatic updates might seem annoying when you have to wait for updates or for the device to restart, but these updates serve an important purpose. Updates allow the security and firewall to be updated often. 

All updates also go through reviews as well and cannot be downloaded until they have been signed and verified by Google. 

Transport Layer Authority Keeps Google Nest Secure

This is another layer of protection that Google has added to the Google Nest to make sure your network doesn’t get attacked. When you search the web, all the communications and signals are secured and recorded by the Transport Layer Authority. 

This is put in place to make sure no one can see your messages and no one can change your messages and passwords. 

Overall, all these things combined make the Google Nest one of the most secure WIFI devices on the market. 

Final Thoughts 

Making sure to have a secure WIFI device is important because you don’t want your information stolen and used by other people. The Google Nest implements several different security measures including a firewall, WPA2/WPA3, automatic updates, and the Transport Layer Authority.
