Abstract: Disclosed herein are methods, systems, and processes to configure and facilitate selective and granular multi-customer support access in cloud-based cybersecurity computing environments. A request to authorize a multi-customer support account (MCSA) is received. Customer accounts that include an anchor tenant customer account and several secondary tenant customer accounts as well as a set of applications associated with the customer accounts are identified. The MCSA is configured to selectively access customer accounts and granularly access associated applications by being designated with a set of varying access limits for the anchor tenant customer account and another set of varying access limits for the secondary tenant customer accounts, each set of varying access limits being made applicable to various instances of applications associated with each of those customer accounts.
