How can you trust links sent via email and SMS?

Malicious attacks are a growing issue for mobile devices. They don’t just target your browser or email as you can receive fraudulent text messages as well. The Netcraft mobile apps ensure that you are protected from these attacks wherever you go.

By analysing log files recovered from phishing sites, we found that over two thirds of visits to phishing sites are from mobile devices. The Netcraft app provides rapid protection against phishing threats, with new attacks blocked as soon as they’re detected by us.
