Sassafras is the best company that I have experienced for customer & technical support. Over the past year, I am instantly connected with a knowledgeable technician who is genuinely willing to work out any licensing problem.
Usually when companies make a great product and grow in size as a result, customer support suffers. Not so with Sassafras. They focus on one product and support it perfectly. KeyServer is an amazing product but its support is even better.
