AT&T Cybersecurity, a division of AT&T, one of the United States largest telecommunications companies, has discontinued its AT&T Secure Email Gateway service, no longer supporting new customers or contract renewals.
AT&T Cybersecurity was launched in 2019 after AT&T acquired threat intelligence vendor AlienVault. The AT&T Secure Email Gateway service was a relabelled version of Proofpoint Essentials – a market leading email gateway service aimed at the SMB market.
In a letter to affected customers, AT&T Cybersecurity wrote:
“Effective 12/31/2021 AT&T will no longer provide AT&T Secure Email Gateway (SEG) service. In addition, beginning 12/31/2020 we will no longer be able to support moves, adds, changes or contract renewals on this service.”
Existing customers will likely receive support until the end of their contract period. It’s unknown whether the AT&T SEG will continue under a new partnership, or if AT&T will continue their current focus on enterprise threat intelligence and endpoint security.
