Barracuda IM Firewall - Barracuda Networks, Inc.

Demo Says
Barracuda Networks has carved a niche in the e-mail marketplace by offering an affordable solution to spam and virus problems. This new product follows suit, providing a managed environment for real-time messaging that protects businesses from the vulnerabilities of instant messaging, the next frontier for malicious activities.

We say:

Highly competitive space and its still unclear whether these apps generate enough money. IM Logic, FaceTime, Akonix, OmniPod, IBM/Lotus, Jabber all compete. Barracuda's appliances are hot selling however.
