I like that it's easy to use and has all necessary features you need as an admin/security person at your organization.
It also provides great support when needed so there are no complaints from me about anything specific related to this product. The only thing I dislike is how slow their response time can be sometimes - but they do provide excellent customer service! We've been using ThreatStack since we started our Cloud Security Program (CSP) over 5 years ago now and have never had any issues or problems while working together. They're always willing to help out whenever something comes up and solving those small things makes us feel more confident knowing everything will work just fine once again after resolving them.
