FRAUD ALERT: Phony emails to solicit goods or gain access to supplier information have been attempted by impersonators posing as Sandia employees. These emails can be very convincing! Legitimate email addresses from Sandia will always end in “@sandia.gov”. If you are ever suspicious of an email for any reason, reach out to your subcontracting professional (or to isupplier@sandia.gov) separately to inquire as to the authenticity of the request.
