In the press releases following the announcement of Broadcom announcement it was stated, "Broadcom Software Group (which is run by Symantec) will rebrand and operate as VMware, incorporating Broadcom's existing infrastructure and security software solutions as part of an expanded VMware portfolio"
So why does everyone say that Carbon Black is going to get the axe? It seems like Broadcom actually needs VMware's security solutions and might even grow that BU.
