Threat Protection vs. UTM Protection vs. Enterprise Protection

Will link shows you what each  offering has. In reality almost nobody needs are exactly the same or 3rd party devices are used to  achieve the  protection need for a business ( the one box  show is hardly used in big org/VLE/ISP/etc...)

e.g 

 AdvMalware Appliance ( inquest,feye,etc..)

 NonFTNT IPS  device ( again you have quite a few   IPS vendors with proven devices for IPS )

 A web-security-gateway ( websense, bluecoat,ciscoironport,etc...)
