The Thesis
Zscaler kills the VPN.
In the old world (Castle & Moat), you connected to the corporate network. In the new world (Zero Trust), you connect to nothing; you connect through Zscaler to a specific app. The thesis is that Zscaler is the Switchboard of the Internet for enterprise traffic, sitting between the user and the application, inspecting every packet.

- The Product: Secure Web Gateway. Protecting employees browsing the internet (blocking gambling sites, malware downloads).
- The Moat: Proxy Architecture. Zscaler runs inline (Man-in-the-Middle). This is hard to build at scale (150 data centers).
