Secure

You can surf in safety with Ubuntu – confident that your files and data will stay protected. A built-in firewall and virus protection are available. And if a potential threat appears, we provide automatic updates which you can install in a single click. You get added security with AppArmor, which protects your important applications so attackers can’t access your system. And thanks to Firefox and gnome-keyring, Ubuntu helps you keep your private information private. So whether it’s accessing your bank account or sharing sensitive data with friends or colleagues, you’ll have peace of mind when you need it the most.

Why is it free?

Ubuntu is brilliant. It’s no wonder our users ask how all this can be free. The answer is simple.
It’s open source.
Our global community is made up of thousands of people who want to help build the best open-source operating system in the world. They share their time and skills to make sure that Ubuntu keeps getting better and better. From IBM to Google, Firefox to Wikipedia – some of today’s best software is based on an open-source model. Shared efforts. Shared principles. No cost.
