Does anyone know why this code is required for login and what it does?? It seems to be from a company called "iovation" which says:
What is iesnare?
iesnare is simply the name of the web services that iovation has developed to fight fraud and criminal activity. If consumers examine the code of a webpage protected by iovation, they may see references to API calls to iesnare. Unfortunately, because of the nuanced way in which device-intelligence fraud solutions work and the nature of the fraud and abuse they stop, misinformation sometimes takes hold. We hope this page helped clarify the facts.
Still not sure why Ring Central requires this code to login to their service. If I unblock IESnare, login works correctly.
