Network threat prevention
Webcam & microphone protection

Pricing

Introductory pricing is aggressive at $29.99/yr for 5 devices, though renewal rates jump — watch for that when the first term ends.

UI / UX

Autopilot mode makes sensible decisions without prompting, and the dashboard is clean, though occasional upsells for VPN/password-manager upgrades interrupt the flow.

Frequently asked questions
The free tier covers core real-time antivirus on Windows and scores well in lab tests, but it lacks the firewall, ransomware remediation, and full VPN of the paid suite.
