How the enterprzes are doing the https filtering? for the https filtering, you need to decrypt the packet to evaluate its contents for the filtering and if you do it then its like a man in the middle attack. There are devices available to do the https filtering doing deep packet inspection technology but how they cope with the legal legislation for financial sector. like people are using https bank sites to made transactions and if you are decrypting the packet then you will act like a man in the middle. Correct me if i am wrong. your explanation on this will be much appriciated.
