D&B's New Security Protocol May Keep You from Accessing Your Company's Data

Updated: Mar 3, 2020

D&B's free Company Update and iUpdate portals are no longer available.

This post has been updated to include information about DUNS-Manager® platform.

If you have previously viewed or monitored your D&B file via the free Company Update or the official iUpdate owner's portal, those services are no longer available.  D&B has completed their recent online data security upgrade, effectively putting an end to their iUpdate and Company Update platforms, and the new security procedures could prohibit you from being able to access the raw data in your D&B credit profile. Unless you are subscribed to a Creditbuilder or other paid service, there is now only one way to view the data in your D&B file: DUNS-Manager®

D&B's new security process requires that specific owner's information be entered into the system to verify a principal's identity in order to gain access to the site. Whether that is the business owner themselves or someone assigned that responsibility — they'll need to undergo an intense security process that requires answers to four new (and varied) security questions.
