Windows security is generally built into any device running Microsoft’s operating system. It protects your devices and files from malware and hacker attacks with a variety of techniques. This includes basic antivirus protection, a firewall, and other tools to prevent data loss. You can manage and access these settings using the Windows Security application or a small shield icon within the notification area on the taskbar.

Microsoft Defender Antivirus is bundled with Windows. In early versions of the software it was known as Windows Defender Security Center. The application is free and offers chip-to- cloud protection. It can also be used in conjunction with other security tools and is able to detect threats that other security solutions are unable to detect.

One of the main features is the reputation-based security which makes use of a massive online database to analyze websites and apps for their reputation scores. If a site or program has a low score the program or site will be blocked from running on your device. It was effective in blocking malware and phishing sites in our tests. However, it wasn’t able to block nearly as many as other third-party competitors.

Other features include firewall and network protection which is a way of monitoring the network you are using and the apps you use in order to determine their safety. Another feature is Device Security that allows for advanced hardware-level features such as core isolation. This feature can be used to protect your device from specific kinds of attacks. However, you will need to use an compatible computer to benefit from.
