Don't assume that SIEM replacement is always the answer - that's simply not the case. In fact, after this analysis you may feel much better about your original SIEM purchase, with a much better idea (even a plan!) to increase usage and success.

It's time to slay the sacred cow of your substantial SIEM investment, and figure out objectively what offers you the best fit moving forward.
