ARMONK, N.Y. ( TheStreet) -- IBM ( IBM) continued its M&A tear on Thursday, snapping up privately-held BigFix. The BigFix acquisition is IBM's eleventh security deal since 2006, reflecting the tech giant's desire to bolster its software story. IBM has not revealed the value of its latest deal, but will use BigFix's technology to lock down PCs and mobile devices.
BigFix's software ascertains whether specific devices within companies' IT infrastructures are in compliance with corporate security standards. The software can make security fixes across as many as 500,000 machines in a matter minutes, according to IBM. The likes of Symantec ( SYMC) and McAfee ( MFE) have much greater visibility in the security market than IBM, although the tech powerhouse is extending its "smarter data center" into desktops and networks. Companies using BigFix's software include SunTrust Bank ( STI), Allianz Global Investors, and BlueCross/BlueShield of Alabama. The deal is expected to close in the third quarter of 2010. IBM, which competes with Oracle ( ORCL), Hewlett-Packard ( HPQ) and Microsoft, ( MSFT) is in the throes of a major software push. The Armonk, N.Y.-based firm has vowed to derive 49% of its profit from software by 2015, up from 42% last year. IBM's software business brought in $5 billion during the company's recent first-quarter results, an 11% increase on the same period last year and almost a quarter of the firm's total revenue. Recent strong results from Oracle have also raised expectations for IBM's software business. The tech bellwether reports its second-quarter results later this month. Analysts surveyed by Thomson Reuters expect IBM to post second-quarter earnings of $2.58 a share and revenue of $24.25 billion. -- Reported by James Rogers in New York Follow James Rogers on Twitter.
