Feature breadth that matters

Beyond the headline, Bitdefender ships Scam Copilot AI assistant for SMS, email and chat scam detection, Bitdefender VPN powered by Hotspot Shield's Hydra protocol with WireGuard alternative and Cross-platform parental controls with location tracking on iOS and Android.
