Hoping to ramp up its on-demand offerings, Dell Inc. has announced plans to acquire information-security company SecureWorks, Inc.

SecureWorks processes more than 13 billion security events and sifts through more than 30,000 malware specimens each day. Clients include more than 1,500 banks and credit unions and the company protects trillions of dollars in financial assets. Founded in 1999, SecureWorks is headquartered in Atlanta, Ga., and its 700 employees serve thousands of clients in 70 countries. The company project 2010 revenue of more than $120 million.

Said Peter Altabef, president of Dell Services, in a statement: “SecureWorks is a recognized industry leader in information security services and its offerings and expertise will immediately enhance our solutions portfolio. We look forward to welcoming SecureWorks team members – who bring their passion and dedication to serving clients with best-in-class security services – to Dell and our clients.”

Most recently, Dell purchased data storage company Compellent Technologies. Dell will pay $27.75 per share in cash for each share of Compellent for a total equity value of approximately $960 million, and aggregate purchase price of approximately $820 million, net of Compellent’s cash. The acquisition strengthens Dell’s cloud computing and storage prowess against formidable rivals including Hewlett-Packard and IBM.

“Compellent is a natural complement to Dell’s expanding enterprise storage portfolio. The Compellent storage platform will enable Dell to provide customers additional mid- and high-end network storage solutions that simplify and reduce the cost of data management,” said Brad Anderson, Dell’s senior vice president of the Enterprise Product Group. 

In early September, Dell finally threw in the towel on a drawn-out bidding war for another storage provider, 3PAR. The company called it quits after HP upped its offer to roughly $2.1 billion, representing $33 per share, an increase from the prior offer of $30 per share. 3PAR issued a statement calling the new offer from H-P a “superior proposal.”
