The most important thing I like about this product is that it has saved my organization from several attacks which were carried out through our APIs by other companies or third parties who had access to them for development purposes. It's been useful in protecting us as well as all of our customers' applications against such threats. There isn't much i dislike about salt security apart from its price tag but considering that they have an annual subscription plan then there shouldn't be any issues with their pricing policies either. We've used salt-api extensively since last few years where we offer many different web services via api using various languages (python/ruby).
