The decay $K^{+} \rightarrow \pi^{+} \nu \bar{\nu}$, with a very precisely predicted branching ratio of less than $10^{-10}$, is one of the best candidates to reveal indirect effects of new physics at the highest mass scales. The NA62 experiment at CERN SPS is designed to measure   $Br(K^{+} \rightarrow \pi^{+} \nu \bar{\nu})$ with a decay-in-flight technique, novel for this channel. NA62 took data in 2016, 2017 and 2018. Statistics collected in 2016 and 2017 allows NA62 to reach the Standard Model sensitivity for  $K^{+} \rightarrow \pi^{+} \nu \bar{\nu}$; the analysis of the 2018 data leads to the most precise measurement ever performed. The preliminary result of $Br(K^{+} \rightarrow \pi^{+} \nu \bar{\nu})$ measurement from the analysis of the full data set 2016-2017-2018 is presented, and prospects for future reviewed.
