Zscaler

Zscaler is built for companies that want security checks to happen in the cloud instead of through a traditional office firewall. By our assessment, its strongest point is the zero-trust and secure web-gateway approach, which fits modern traffic better than the old habit of trusting everything inside the network edge. The trade-off is that this kind of security stack asks for careful setup and a company willing to route access through a central platform. In practice, it is less visible than endpoint antivirus but sits deeper in how employees reach apps and the open web. Zscaler belongs among cloud security vendors, and it is a United States company.
