Windows security is usually built-in to all devices running an version of the Microsoft operating system. It safeguards your devices as well as files from hacker attacks and malware by using a range of methods. This includes basic antivirus protection and a fire wall and other tools to prevent data loss. You can access and manage these settings using the Windows Security application or a small shield icon in the notification area on the taskbar.

Microsoft's own antivirus software, Microsoft Defender Antivirus, is included with Windows. In early versions of the program, it was referred to as Windows Defender Security Center. The application is free and offers chip-to- cloud protection. It also works alongside other security solutions and can detect threats that other solutions miss.

One of the key features is the reputation-based security that makes use of a huge online database to check websites and apps for their reputation scores. If a website or application has a low score, it's blocked from running on the device. It was effective in blocking malicious programs and phishing websites in our tests. However, it didn't block as many third-party competitors.

Other features include firewall and network protection which examines the network you are using as well as the applications you use to determine their safety. Another feature is Device Security that provides advanced hardware features such as core isolation. This feature can be used to protect your device against specific kinds of attacks. However, you will require a computer that is compatible to make use of.
