From the beginning of the DMARC project we have received input, support, and data from our Sponsors and Supporters. During 2015 and 2016, this included monetary donations that supported full-time staff. We are deeply grateful for their participation – past, present, and future.


Our sponsor Farsight Security became part of Domain Tools in 2021. We’re grateful that Domain Tools wishes to continue to support our efforts going forward.
