Key findings from Palo Alto Networks Application Usage and Risk Report, December 2011 (USA Only). The slides provides insight into application activity that is based on network application assessments that show what is really happening on corporate networks.z .

1. Five Facts About Application
Usage on Enterprise Networks
in the USA
Application Usage and Risk Report
December 2011

3. Average number of social networking
applications per organization?
A total of 69 different social networking applications were
found in 96% of the 395 participating organizations with an
average of 15 found on each network.

5. Which application is used more heavily?
Based on the percentage of social networking bandwidth
consumed, Zynga was used more heavily (7%) than
Linkedin (4%). Facebook and Twitter consumed 40% and
21% respectively.

6. Active social networking applications (games, plugins,
posting) are used more heavily in the USA than they are
globally. Facebook is a clear dominant player with 40% of BW
consumed.

8. Average number of browser-based
filesharing applications per organization?
A total of 55 different browser-based filesharing
applications were found in 95% of the 395 participating
organizations with an average of 11 in each.

9. Browser-based filesharing use cases: work or
entertainment. Both uses have a common set of business
and security risks that organizations must address.

11. The number of applications
using Port 80 (tcp/80) only?
The number of applications that ONLY use Port 80 is 270 or
24% of the 1,121 applications found in the participating
organizations.

13. Percentage of total bandwidth consumed
by applications not using tcp/80?
54% of the total bandwidth is being consumed by 534 (48%
of 1,121) applications that DO NOT USE port 80 at all. Ever.

14. Port 80 only security is shortsighted. The common
perception is that Port 80 (tcp/80) is where all the traffic and all
the problems are. A port 80 emphasis is an absolute
requirement; but too much focus is shortsighted.
