Sullivan Environmental Services appears to be a specialized environmental consulting and professional services firm that handles site assessments, regulatory compliance, and remediation projects. In the course of business operations, such professional services typically collect and store sensitive personal data from employees, clients, and contractors, including names, contact information, Social Security numbers, and banking or financial details. In 2026, the company officially reported a cybersecurity incident to the New Hampshire Attorney General's Office following an unauthorized security event affecting its network environment. If you received a data breach notification letter in the mail, it means your personal information was potentially compromised during this incident, and the letter provides further guidance on steps you can take to protect your identity.
