IBM is widely expanding the intelligence gathering functions available to its security-event management (SEM) product, QRadar Security Intelligence Platform, as well as designing a virtual-appliance version of it that works on the VMware platform.

IBM intends to make the security information and event management (SIEM) technology gained through the acquisition of Q1 Labs, which was officially closed yesterday, the centerpiece of IBM's broad security product portfolio.

IBM has acquired database security vendor Guardium, it said Monday, confirming earlier reports. Terms of the deal were not disclosed.
