Chrome OS ships with Google’s powerful built-in security features that protect users from the majority of online threats. Our 2026 deep-dive explores what Chrome OS security covers and where additional protection is advisable. Every Chromebook automatically benefits from Verified Boot, which checks the integrity of the OS on every boot. The sandboxing architecture isolates every web page and application in its own protected environment. Google’s Safe Browsing API protects against malicious websites across Chrome and apps. Automatic updates ensure your Chromebook always runs the latest security patches. However, Chrome OS security has limitations: it does not scan Android apps before installation, does not include a built-in VPN, and offers no anti-theft data-wiping. Users who install Android apps from outside the Play Store should consider additional malware scanning.
