If your data was in a Kemper breach, do this
- Freeze your credit with all three bureaus and place a fraud alert. This kind of exposure sharply raises your identity-theft risk.
- Expect targeted phishing that references this breach — be skeptical of unexpected emails asking you to log in, verify, or pay.
- Watch for scam texts and SIM-swap attempts, and avoid using SMS as your only two-factor method where you can.
- Your physical address may be circulating — remove yourself from data-broker and people-search sites to lower your doxxing risk.
- Remove your personal information from data-broker sites so the leaked data can’t be combined against you — GalaxyWarden files those removals for you.

How we grade Kemper
The DoxxScan™ Rating is an automated, informational estimate of how exposed a company’s customers may be if the incidents on its public record are accurate, derived solely from that record — the number of incidents, how recent and severe they were, the sensitivity of the data involved, and who established the incident. Most incidents we track are unverified listings published by ransomware and extortion groups; those are accusations, not established facts, and they count for less. A lower rating indicates a higher likelihood that personal information tied to this company is circulating and could be used to dox or target individuals. It is not an audit, certification, or assessment of the company’s current security controls, and it does not represent present-day risk. It may rely on incomplete or unverified public reports and can change as new information emerges. Recent Breaches and GalaxyWarden are independent and are not affiliated with, and do not endorse, any company named here.
