Emeryville, Calif., September 5, 2013--Sendmail today introduced Sentrion Rogue Email Application Control (REAC) 2.0, the first inside-threat protection application with new Big Data search capabilities to further protect organizations against the growing internal threats posed by machine-generated email, which accounts for more than 50% of all corporate email traffic.
