Symantec Messaging Gateway is een product voor het beveiligen van in- en uitgaande mailstromen. Het borduurt voort op Brightmail, dat in 2004 werd overgenomen door Symantec, dat op haar beurt weer in 2019 door Broadcom werd overgenomen. Hoewel beide overnames alweer even geleden zijn gebeurd, komen ze nog terug in de naam en beschrijving van het product. Het programma biedt antispam- en antimalwareopties, geavanceerde contentfiltering en data loss prevention, en biedt ook encryptieopties aan door te integreren met Symantec-encryptieproducten. SMG kan op een bijbehorende hardwareappliance worden gedraaid of virtueel in VMware, Hyper-V, KVM of binnen Azure. Versie 10.8.0 is verschenen met de volgende veranderingen:
