Something along the lines of his first point about platforms has been the bane of my existence for the better part of three years. These security tools we spend so much money on, make interacting with, and analyzing the data they generate almost impossible. They all have their built-in reporting mechanism, but what if I want to see if the vulnerability found in the Tenable Nessus scan relates to the data from our McAfee Endpoint solution? I have to copy and paste the host names, and their associated CVEs, then run a report to dump all of our endpoint data for the entire enterprise, then hit ctrl-F. It's hard to perform actionable security in any way other than in the rearview mirror.
Anyone have any thoughts on how successful I might be if I tried to build a platform that would take data from multiple vendors to perform analysis? Would the vendors be amenable, or would they fight against me?
My guess is that for the most part the vendors wouldn't care - which would mean that every update cycle you would have to spend a day patching the platform to cope with whimsical proprietary format changes. Actively hostile vendors could easily make it very difficult to scale out the platform, even if they didn't target you for legal action.
Ultimately what we need here are open standards at all levels, that is the only way you can have a stable interaction of systems and keep the market open and competitive.

The vendors would definitely fight with you. From their perspective, they have a profitable business model and they don't want anyone encroaching on it. If there is a market need, then they will be the one to fill it. In any case, don't expect any help from them.
Needless to say, my interactions with antivirus companies have rarely been positive.
Add-on security never really works except inept opponents, but it's a very profitable business.
