I work at a small firm that used this service for our DDoS mitigation needs and it was very helpful.
The team is knowledgeable and easy to communicate with, however it can sometimes be hard to find someone within the organization that you are able to speak with directly. We were looking for an efficient way to deal with large scale DDoS attacks and found ESENTIRE to have what we needed. They had experience with large scale DDoS attacks and helped us mitigate issues that would otherwise have caused problems for our clients.
