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. Recent Breaches and GalaxyWarden are independent and are not affiliated with, and do not endorse, any company named here.
