Which Microsoft security software is right for me?
Choosing the right Microsoft security software depends on how you're using your PC.
Most of our security software uses the same technology and offers the same level of protection.
However, enterprise software has features that are useful in a work environment, such as managing multiple computers and remote deployment.
You don’t usually need these features at home or in a small business.
See the Microsoft security software page for a list of our software.
