Safest Companies — Best Security Record
Companies ranked by their Recent Breaches Safety Grade — a higher grade means a cleaner publicly known breach record. This ranking includes companies with no known breach at all. A high grade is not a guarantee of safety or an audit of current security controls.

The Recent Breaches Safety Grade is an automated, informational rating of a company’s publicly known breach history — how many breaches are on record, how recent and severe they were, how much data was exposed, whether ransomware/extortion was involved, and how well each claim is verified. A higher grade means a cleaner known record. It is not a guarantee of safety, an audit, or a certification: the absence of a known breach does not prove none has occurred, and the grade says nothing about a company’s current security controls. Unverified leak-site claims are weighted down but may still be incomplete or inaccurate.
