2021 Leakage Coverage Study

Telcos were asked to assess the extent of their monitoring coverage per the categories in the leakage catalogue. Participants in the survey each received a bespoke report that compared their coverage to their peers. A public summary of the results can be seen below or downloaded from here.


The 2021 report includes a comparison to the results of the first leakage coverage study, performed in 2019. The report of the 2019 can be downloaded from here.
