Your Computer's Built-In Security Features You Might Not Be Using

Built-In Security Features You Might Not Be Using

When most people think of computer security, they imagine paid antivirus software or complicated apps. The truth? Both Windows and macOS come with excellent built-in security features you might already have — you just need to turn them on and let them do their job.

Let’s look at the most important ones on each system.

🛡️ Windows: Microsoft Defender Antivirus

• Runs automatically in the background.

• Provides real-time protection against viruses, ransomware, and phishing.

• Updates through Windows Update to stay current.

👉 Tip: Make sure updates are enabled so Defender is always up to date.

🔒 Mac: XProtect & Gatekeeper

• XProtect is Apple’s built-in malware scanner that runs silently.

• Gatekeeper blocks unknown or suspicious apps from running.

• These work together automatically — no setup required.

👉 Tip: Only install apps from the App Store or trusted developers.

🔐 Drive Encryption

Windows: BitLocker (Pro editions) 

• Encrypts your entire drive so stolen data can’t be read.

• Found in Control Panel → System & Security.

Mac: FileVault 

• Encrypts your Mac’s hard drive automatically.

• Turn it on under System Settings → Security & Privacy.

👉 Tip: Encryption protects your data even if your computer is lost or stolen.

🌐 Safer Browsing

Windows: SmartScreen Filter 

• Warns you before visiting dangerous websites or downloading unsafe apps.

Mac: Safari Fraudulent Website Warning 

• Alerts you about known phishing websites.

👉 Tip: Always pay attention to these warnings — they’re easy to click past, but they’re there to keep you safe.
