Mobile Device Protection by Netcraft defends against cybercrime with real-time protection for Android, iOS, and Amazon devices. It protects from malicious sites, SMS, phishing, fake shops, and malicious scripts like JavaScript skimmers and cryptocurrency miners. It allows for easy reporting of suspicious sites and provides rapid protection against phishing threats, blocking new attacks as soon as they are detected. It supports built-in browsers and many popular third-party apps powered by Chrome or Safari. The Android app relies on the Accessibility service to interact with browsers on the phone. The iOS app size is typically 80 – 95 MB once installed and configured, while the Android app is smaller, typically between 2 – 6 MB. The app struggles to block calls and SMS from fraudulent numbers due to the ease of faking caller IDs.
