If you received a notification letter from Sullivan Environmental Services, Inc., it is crucial to review it carefully for any specific recommendations. Generally, experts advise monitoring financial accounts and credit reports for any suspicious activity. You may also consider placing a fraud alert or security freeze on your credit files to prevent unauthorized accounts from being opened in your name.
