HP Closes $1.5 Billion Acquisition Of ArcSight

Hewlett-Packard this morning announced that it has now completed the acquisition of security and compliance management company ArcSight for $43.50 per share, or an enterprise value of $1.5 billion.

ArcSight helps protect enterprises and government agencies against cyber threats and other risks by providing complete visibility and insights into their IT infrastructure across all users, networks, datacenters and applications.

HP says further details on the ArcSight product integration into the HP Software and Solutions portfolio as HP expands into the security information event management market will be announced at a later date.

Just yesterday, HP announced that it has completed its tender offer for ArcSight, which was commenced on September 22, 2010. It said it expected to complete the acquisition within days – looks like it took them only one.

This acquisition follows HP’s $2.3 billion acquisition of data storage company 3PAR. Earlier this year, it spent $1.2 billion on the acquisition of Palm.
