1. A system configured to analyse transfer of data over at least one network, the system comprising:
- a secure analysis device, comprising a hardware processor, configured to capture samples of traffic data being transferred over the at least one network in respect of a subset of users selected from a user base of the at least one network and to analyse the samples of traffic data to identify data relating to potential unlicensed data transfer by the subset of users, wherein selection of the subset of users is based upon comparing levels of potentially unlicensed data transfer of users in the user base against a threshold; and
a processing device, comprising a hardware processor, configured to;
(a) receive results of the analysis by the secure analysis device of data transfers by the subset of users;
(b) determine from the results a measured number of unlicensed data transfers, an estimated number of unlicensed data transfers and an estimated number of users having performed unlicensed data transfers;
(c) derive at least one metric indicative of unlicensed data transfer by the user base based on the measured and estimated determinations; and
(d) use data relating to the at least one metric to control network hardware to prevent at least one of;
(i) further data transfer, and (ii) further network access.
