Cyber threats are the weapons that hackers and cybercriminals use. Cyber security solutions like Device Protect help defend you against the following types of common cyber threats.


Malicious software that corrupts and steals data, usually once you click an attachment to an email. 


Malicious software that infects your device and restricts access until a ransom is paid. 


Email or SMS-based scams that pretend to be from trusted sources and trick you into providing data like your login and banking details. 


Designed to spread, virus-like, from device to device and alter or stop them working altogether.

We’re Australia’s largest carbon neutral organisation

How we’re minimising our environmental impact

We’re reaching for our climate goals with Telstra being recognised as Australia’s largest certified carbon neutral organisation since July 2020 under the Climate Active scheme. We also have a growing ambition to reduce our environmental impact with:  

100% renewable energy generation

By 2025, we aim to enable 100% renewable energy generation equivalent to our consumption. We’ve invested in three solar and wind farms which will create enough energy to power 125,000 households.


50% reduction of emissions

By 2030, we aim to achieve a minimum 50% reduction of absolute emissions. We’ve also set a target to reduce emissions from our customers with more energy-efficient products such as modems.  

Recycling program

Our program recycles nearly 5,000 tonnes of e-waste per year. And we’re committed to all recycled material packaging by 2022.
