About App Security Group:
This group provides security & visibility for SaaS applications being used by organizations (i.e. used by Cato’s customers).
We are doing it by integrating with these 3rd party vendors ( like Salesforce, Slack, ServiceNow, Dropbox etc.) using their public APIs, fetching data on various activities (sign-ins, sharing, exporting etc.) and bringing it into Cato platform, enforcing relevant security policy in supported apps.
We’re expanding our capabilities by designing & building an infrastructure that will allow us to accommodate a large scale of applications and support additional use cases brought up by Cato’s product team.
