Microsemi Corporation Buys Arxan Defense Systems

In what is the firm's second buy in as many days, Irvine-based Microsemi said Wednesday that it has acquired Arxan Defense Systems, a provider of anti-tampering, anti-piracy, and other software products. Financial terms of the buy were not announced. Microsemi said that Arxan serves defense clients, including customers building major weapons systems, who use its products to meet mandatory, U.S. Department of Defense directives. Microsemi said the buy will both help it with the defense and non-military markets. The buy comes one day after Microsemi said it would buy VT Silicon, a developer of radio frequency integrated circuits (CTI) for the mobile wireless broadband market.
