Hello Namit and Rahul,

How is Application visibility and control featur in ASA-X , differ from  normal inspection .

Thanks in advance for ur kind help.



Hi Vishaw,

Thanks for your question. The AVC offered by the CX is way more enhanced and complex in its capabilities. The AVC offers more than layer 7 inspection, it adds intelligence using the data in the layer 3/4/7 information. It recognizes a large number of applications and microapplications. Hence, it enables the administrators to control access to applications forspecific set of users or groups. Also, we can control features within a microapplication.

e.g. block one game in  facebook and allow another one

Hope that helps.





I have a question related to the ASA and cloud security (scansafe), are you able to give me details on the connection limit for a 5545X when it is configured to use scanafe for websecurity? Is it the usual connection limit, ie. 750,000?

I look forward to hearig from you.

very best wishes

Mike Jackson
