← Lowest Risk
Highest Risk →
We consider CZ.CZNET to be a potentially low fraud risk ISP, by which we mean that web traffic from this ISP potentially poses a low risk of being fraudulent. Other types of traffic may pose a different risk or no risk. They operate 247,972 IP addresses, none of which are running high risk services. They manage IP addresses for organisations including Telefonica O2 Slovakia s.r.o., Internet for school, and Czech Telecom a.s.. Scamalytics see low levels of web traffic from this ISP across our global network, little of which is, in our view, fraudulent. We apply a risk score of 1/100 to CZ.CZNET, meaning that of the web traffic where we have visibility, approximately 1% is suspected to be potentially fraudulent.
