The commercial package has less engines than the free one. How confident should I be in the results?

The detection ratio is influenced by the number of engines in the program. We regularly publish the package efficacy report where we show the detection rate of various packages compared to the "free" cloud version (the ones with the most engines). The detection ratio with the existing engines in the cloud commercial package is very close to 100% because we have chosen engines with good detection rates to be part of our program, but also engines that have good scan times (because the total scan time will be the time of the slowest engine). OPSWAT pays royalties to all the commercial engines.
