Discovery is a process of detecting certificates based on the conditions specified in the scan profile. You will get all known and unknown certificates associated with your network (including subdomains) and internal IP addresses in one cloud inventory that’s easy to access.
To run a Discovery, choose the type of scan between internal (available for Standard and Business pricing plans) and external networks and create a scan profile (a set of conditions for the particular scan). You can create an unlimited number of scan profiles (available for all pricing plans except the free one) and schedule them to be performed on a daily or weekly basis.
