Pros
It was a great company to work for while it was independent and might be bought from Idera by a competent company someday.
Cons
PreEmptive has been bought by Idera, a disgusting bloated shambling corpse of a software company whose business model appears to involve buying good software companies, gutting them, and using their reputations to cover up their own terrible reputation. I would consider any reviews of PreEmptive on Glassdoor that don't directly address Idera's acquisition of PreEmptive to now be deceptive. I have reached out to Glassdoor to see if there's anything we can do about them because I don't want anyone to be deceived by PreEmptive's good reputation into working for Idera. See Idera's reviews for a more accurate assessment.
