With all of my clients I have found that there is nothing they dislike about this product. It works as well or better than any other solution out there and has been very easy for them to implement with their current infrastructure. Their only concern was price however if you are looking at it from an enterprise perspective then it does make sense. If your not in an Enterprise environment then maybe look elsewhere but otherwise its one of the best solutions available. We use Elfiq primarily for our VPC connections which allows us to connect through AWS/Azure without having to worry about security issues such as IP addresses etc. Since we have so many customers using different technologies (DevOps, AI, Big Data) we need to be able to connect securely across these environments.Elfiq provides us with that ability.
