Great Product, wish they had Email Archiving when I was still using it.
SPAM decreased by a huge percentage as compared to the previous product we were utilizing.
Extremely good at catching SPAM, easy to setup, easy to manage, and all around great performer. Customer focused, excellent customer service response and support.
Not really a true con, but at the time we were looking towards email archiving and they didn't have an offering to support that. After trying an interim solution combining Modusgate with GFI Mail Archiver, we ultimately left the product for Mimecast.
