For the sum of $865 Million cash, IBM is outright purchasing Micromuse
in order to add the company to it's Tivoli branch. Tivoli is a branch of IBM geared to support business software infrastructures, among other things. Primarily, Micromuse does diagnostics and schematics, and IBM hopes to use their technology in order to create self-managing and self-diagnosing software for both security and stability, such as the ability to be able to intelligently detect network intrusions. IBM absorbs the more than 1800 customers Micromuse currently has.
