Take the time to learn the ins and outs of the product and you'll most likely be satisfied with it if your company is an SMB. If you need compliance reports, OSSIM is too small for you, you'll need to go with USM or USM Anywhere.

Exabeam is very good at processing lots of logs without excessive licensing costs. It has a professional support team that's very quick to resolve any issues and provides custom parsers quickly and enables our analysts to search vast data sets without having to wait long for results to be returned. The product is getting more mature with new features every major release.
Everything is done through MSSP and installation pro services. Once those hours are burned up, then you're on your own without a lot of help. Typically the pro services hours aren't enough to get past 60 days and MSSP are hit and miss. We had a miss for installation helpers.
Exabeam Fusion has so many diffferent out reach meetings, webinars, community virtual coffees, and events that you can always stay abreast of what if happening and get new ideas for use cases. Their support actually answers their phones and can respond in chat instantly. With our cloud deployment Exabeam support teams can instantly see our systems and help us.
Originally my organization leveraged alien value due to the lower cost of entry and ability to manage it as a service provider. Unfortunately, after several years of working with this tool, it became unwieldy to use as it felt that almost every useful report had to be created by hand. As other tools have come out with the ability to do automated responses such as Stellar Data processor, we have begun to evaluate alternatives.
