Why IT Professionals Use Our Software
McKenzie Medical Center - 14 Years and Going Strong!
"We have been with MDaemon for 14 years. It has proven to be a stable and reliable platform. The content filters are very flexible. I have an email server that stops most junk and malicious emails from reaching my users. The Instant Messaging is an integral part of our internal communications. It has Calendaring, Tasks, Notes, all configurable. It's a very affordable alternative to more expensive systems."

I would say the most helpful thing has been the cost. We turned to MDaemon when noticing the cost of the Microsoft Exchange Server. We run a busy law firm and this product fits the bill perfectly.

Very easy to customize to fit our requirements. Most other email security software is a one size fits all type of product. Unfortunately, every company has different requirements, Security Gateway makes an extremely flexible package. That is easy to use and set up.
