SSL Inspection at Scale with Proxy Architecture

Zscaler has invested heavily in building a 'Proxy' based architecture which makes it possible to deeply inspect network traffic at an enormous scale, including SSL encrypted traffic. Think about it like a postal service... Zscaler as a proxy, take every box, open it, inspect the contents as we put it in a new box, then send it on to the recipient.

A firewall on the other hand simply looks at the box from the outside; reads the address, the sender, the consignment details sticker, and if it is all in order, just lets it flow past.
