Office of the Ombudsman

The process behind BitSight's guiding principles on independence, objectivity, and integrity.

About Our Appeals Process and Ombudsman

A trusted ratings firm must offer a formal appeals process and an independent third party verifying that the appeals process is fair and unbiased. While we are confident in the accuracy of our data, we believe that any organization using BitSight Security Ratings should have a way to properly dispute their ratings.

Appeals Process

If you disagree with any of BitSight’s findings, you can request a review of the IP addresses assigned to it, verify that the ranges are correct, and request additions or omissions via email to or directly through the BitSight Platform. Removing IP addresses requires the submission of appropriate evidence, such as authorized changes to Internet registries. Alternatively, organizations can use BitSight annotations to add clarifying notes about their IP maps; the company’s third parties or business partners who are BitSight customers will then have access to that organization’s notes. If you are still dissatisfied with the Security Ratings data, you can request an additional review through our ombudsman.


The BitSight ombudsman reviews issues of accuracy, fairness, and balance regarding BitSight Security Ratings. The ombudsman recommends approaches to address any issue and update BitSight data or processes as necessary.

The ombudsman for BitSight Technologies is Michael Cusumano, an MIT professor and scholar. Named as one of the most influential people in technology and IT by, Professor Cusumano is on the Board of Directors of several companies and has consulted for more than 90 organizations worldwide including IBM, Ford, Nokia, and Fidelity.

As ombudsman, he does not report to any internal teams at BitSight; instead he reports directly to the BitSight Customer Advisory Board.
