HOPKINTON, Mass. (AP) ¿ Data storage company EMC Corp. said Monday it agreed to acquire Archer Technologies, a privately held governance, risk and compliance software maker, for an undisclosed amount. EMC said it expects the deal to close in the current first quarter, and that it will not have a material impact on revenue or earnings for the year. Archer will continue to operate from its current headquarters in Overland Park, Kan., after the acquisition. It will become part of EMC's RSA security division. Archer's software helps companies set data and security policies that meet industry and government regulations, and audit and spot new problems on an ongoing basis. EMC said in a statement that Archer's software complements its own security and data loss prevention technology. Shares of EMC added 45 cents, or 2.6 percent, to $17.92 in afternoon trading.
