Brightmail

Brightmail was an email anti-spam software company founded in 1998 by Sunil Paul, best known for its network of "spam probe" honeypot email addresses that fed real-time anti-spam filtering rules to enterprise mail servers. Symantec acquired Brightmail in 2004 for roughly $370 million, and the technology shipped for years as Symantec Brightmail AntiSpam and later Symantec Mail Security; Symantec's enterprise security business was subsequently acquired by Broadcom in 2019. Brightmail today is a defunct brand with no independent developer program or public API surface — www.brightmail.com redirects to broadcom.com and the brightmail.com apex domain no longer resolves. This profile is retained for historical/network completeness rather than active API enrichment.

Brightmail is profiled on the APIs.io network. Tagged areas include Company, Email, Anti-Spam, Email Security, and Security.
