No. Sandfly is completely self-contained. It sends no data back to us, and does not ship potentially confidential data from your systems off-site for analysis. Sandfly is designed to work on networks that are on the Internet, or those that are air-gapped. Nothing leaves the system to a third-party during operation. Although we may offer off-site analysis features in the future, we also recognize that many organizations have spent tremendous amounts of money to secure their data and do not want it sent out to third-party services they do not control. Sandfly was designed to work in isolation without any need to communicate externally.
