Zscaler

Zscaler is a cloud security company that created the 'Zero Trust Exchange.' Before Zscaler, companies used to buy expensive hardware firewalls to protect their offices (the 'castle and moat' approach). But now that employees work from home and apps are in the cloud (like Salesforce, Office 365), that old model doesn't work. Zscaler moved the entire security stack to the cloud. Instead of connecting to your office network via a slow VPN, you connect to the Zscaler cloud, which inspects your traffic instantly and securely connects you to the specific app you need—without ever placing you on the corporate network.
