Need recommendations for Premium Tools

I was asked to find some tools that can be used for malware analysis and intel. Atm, the budget hasn’t been established but I’ll cross that road later.

Currently, the tools used are all open source (Mostly from GREM / SANS) and there have been no problems with that, just was posed with collecting information about paid tooling.

We have IDA Pro and possibly Maltego on the drawing board, what other tools are worth purchasing?
