WiFi Secure is designed to actively provide built-in protection for every device that is WiFi connected to the Internet via your Compatible Modem.

When any device connected to your home / business network attempts to access a website, WiFi secure performs a reputation check via McAfee's Global Threat Intelligence (GTI) platform.

GTI is constantly working to analyse and detect known and emerging cyberthreats. Information provided is near real-time, thus offering the most up to date information to ensure you and your device(s) are protected.

If the website is known to be malicious, access to the website will be blocked. For some sites, you'll also have the option to ignore the warning and continue.

WiFi Secure also blocks attempts to access devices connected to your home or business WiFi including security cameras, baby monitors and smart locks.

As long you have an eligible nbn plan with an eligible modem, you'll be able to use WiFi Secure. Eligible modems include the:

• Optus Ultra WiFi (Gen 2) modem
• Sagemcom F@st 5366TN modem
• Optus Ultra WiFi (Gen 1) modem

What is Optus WiFi Secure?

Optus WiFi Secure™ is a month to month subscription service that protects you and your family from malicious threats while they're online via a WiFi connection from a compatible Optus supplied modem, using an Optus nbn Internet service.

Optus WiFi Secure™ provides security against many online threats such as malicious websites, botnet attacks, and Denial of Service attacks. It helps to make sure all Internet traffic passing through the compatible Optus supplied modem to any device connected to your home or business network is safe from these threats.

Does WiFi Secure provide virus protection?

No, Optus WiFi Secure by itself doesn't provide anti-virus protection. WiFi Secure's primary purpose is to prevent navigation to websites that may contain malicious threats. You can pair Optus WiFi Secure with any recognised anti-virus security product.

Am I eligible for Optus WiFi Secure?

Optus nbn customers with a compatible Optus supplied modem are eligible for Optus WiFi Secure™. Currently, the two compatible modems are the Optus Ultra WiFi modem and Sagemcom 5366 TN modem.

The following current Optus nbn plans (from 7 July 2025) are ineligible for Optus WiFi Secure: 

• Optus Basic nbn
• Optus Everyday nbn
• Optus Fast nbn
• Optus Ultrafast nbn
• Optus nbn Promo plan

What will I see on my bill?

You'll see a charge of $5 per month for Optus WiFi Secure™. When you purchase an Internet Ultimate Plan will also see a discount for $5 per month, as WiFi Secure is included with these plans at no additional cost.

How do I activate my subscription?

Once you've added Optus WiFi Secure™ to your existing plan, your subscription should activate automatically. You can check whether it is active on My Optus app.

You'll need to upgrade your modem to a compatible Optus supplied modem, Optus WiFi Secure will be active when you're connected to the Optus nbn service via your new modem.

If you've signed up to an Internet Ultimate Plan after 29 March 2021 where WiFi Secure is an inclusion, it will automatically be activated for you once your nbn service is activated. There will be no additional action required to set up or turn on the product in this instance.

For customers on an Internet Ultimate Plan prior to 29 March 2021, Optus WiFi Secure will be provided as an inclusion, and customers will need to activate via the add-on section in My Optus app or by contacting Optus.

I've turned off WiFi Secure via the GUI (Modem Interface); why does My Optus App show that it's still active?

If you turn off WiFi Secure via the modem interface, you're still subscribed to the service meaning you can turn it back on at any time but will still be charged.

If you wish to cancel WiFi Secure permanently and no longer wish to be billed for this, please cancel via My Optus app or by contacting us. It will then no longer appear active on your app and you will no longer be charged for the product.

Why isn't WiFi Secure working even though I'm connected to nbn?

Provided you're using a compatible Optus supplied modem and have added or activated the service; Optus WiFi Secure is working. However, please note that whenever rebooting your modem, there may be a 2-5 minute delay for WiFi Secure Service to reconnect, which means the service won't be active during this time. If you're having issues with your service, please contact us.
