Windows security is generally built-in to all devices running a version of the Microsoft operating system. It safeguards your files and devices from malware and hacker attacks through a variety of techniques. This includes basic antivirus protection, a firewall and other tools to prevent data loss. Windows Security or the small shield icon in the taskbar’s notification area allows you to access and control the settings.
Microsoft’s own antivirus software, Microsoft Defender Antivirus, is part of 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 products and is able of detecting threats that other solutions miss.
One of the most important features is reputation-based security, which utilizes an online database to evaluate websites and apps for their reputation scores. If a program or website has a poor reputation, it will be blocked from running on your device. It worked well to block malicious programs and phishing websites in our tests. However it didn’t block nearly as many as other third-party competitors.
Other features include firewall & network protection, which monitors your network as well as the applications you use to determine if they’re safe. Device security is another option that lets you access advanced hardware features, such as core isolation. This feature can be used to secure your device from certain kinds of attacks. However, you will require an operating system that supports it with the device to use.
