I have use case as follow:
Company A and Company B is merged. - Look for a easy allow company A to access a company B internal apps & resource via Zscaler.
Company A - Not Z-Scaler customer, Cloud IdP - Okta for their cloud applications.
Company B - Z-Scaler with ZPA for "internal resource | application access & ZIA for the Web-Proxy. ADFS as IdP- implemented.
Company A users need to access Company B internal applications (Private Access) when they are needed - without interrupting company A access. (still use company A web-proxy for internet traffic, company A own exist client VPN solution to access Company B’s internal resource…)
Please let me you if someone out there had this use case and successfully implemented a working solution.
