Overview
“Symantec” today is an enterprise cybersecurity brand owned by Broadcom — but the name most people picture, the yellow-boxed Norton antivirus on a retail shelf, belongs to a different company entirely. The original Symantec Corporation was founded in 1982 under a National Science Foundation grant to pursue artificial-intelligence technology, merged with the startup C&E Software in 1984, and only turned profitable in its 1989 IPO year (Channel Insider). Its defining move came in 1990, when it bought Peter Norton Computing for $70 million — then its largest acquisition — entering the antivirus market; within two years the Norton unit generated 75% of Symantec’s revenue (Channel Insider). The brand’s later history is a long M&A arc — including the bitter 1997–99 legal feud with McAfee over allegedly stolen Norton code — that ended with the company itself being split in two.
The 2019 split: Broadcom takes the enterprise, Norton goes its own way
In November 2019 Broadcom completed its $10.7 billion acquisition of Symantec’s $2.5 billion Enterprise Security business, which continued under SVP Art Gilliland; the same day, the remaining consumer company — Norton and LifeLock — immediately renamed itself NortonLifeLock (CRN). Broadcom said it would concentrate investment on Symantec’s endpoint, web and data-loss-protection products, target $1 billion in cost synergies, and focus sales on Global 2000 organizations (CRN). The irony of the deal: the consumer segment Broadcom discarded generated just 51% of revenue but a massive 90% of operating income in the quarter before the split (CRN). NortonLifeLock later merged with Avast and rebranded as Gen Digital — so today’s Norton 360 is a Gen Digital product, not a Broadcom one.
Symantec under Broadcom: the Carbon Black merger
Fresh off its $69 billion acquisition of VMware — which owned Carbon Black — Broadcom announced in March 2024 that it was merging the Symantec and Carbon Black businesses into a new Enterprise Security Group unit, tasked with fusing Symantec’s network and data telemetry with Carbon Black’s endpoint-detection-and-response technology (SecurityWeek). Both product portfolios continued operating in their current states, backed, Broadcom said, by its financial stability (SecurityWeek). In 2026 the combined unit launched Symantec CBX, a cloud-native SaaS platform fusing Carbon Black XDR endpoint detection with Symantec attack-prevention capabilities, aimed at mid-market organizations and sold through the channel — positioning Broadcom against Palo Alto Networks, CrowdStrike and Fortinet in the enterprise security market (Channel Dive).
What this profile does not claim
This profile does not cover Gen Digital’s consumer business (Norton, Avast, LifeLock, CCleaner) beyond the split itself — that is a separate company. It does not state current revenue or customer counts for Symantec’s enterprise business, which Broadcom does not break out in the citable sources. It does not adjudicate the 1990s Symantec–McAfee litigation, reporting only that the suits were filed and settled in 1999.
