If your personal information has been compromised in a data breach, it is important to take certain steps to protect yourself:

1. Contact the credit reporting agencies (Equifax, Experian, TransUnion) to place a fraud alert.
2. Close any compromised accounts.
3. Monitor your credit score closely.
4. Report any suspicious activity to the company and file a police report.
5. Create strong passwords for all of your accounts.
6. Set up two-factor authentication.
