Top 40 promotional products supplier Next Level Apparel (asi/73867) has experienced a data security breach.

On Monday, Oct. 4, the Gardena, CA-based company put out a communication about “an incident that may have involved some information maintained in some of our employees’ email accounts, including names accompanied by Social Security numbers, financial/checking account numbers, payment card numbers, driver’s license numbers, and limited medical/health information.”

According to Next Level, an internal investigation determined that an unauthorized person had access to the contents of a limited number of employee email accounts at various times between Feb. 17, 2021 and April 28, 2021. Next Level said it could not confirm if any particular individual’s sensitive information was viewed by an unauthorized person.

Still, out of caution, the supplier was notifying individuals who may potentially have been affected.

“We encourage you to remain vigilant for incidents of fraud or identity theft by reviewing your account statements and credit reports for any unauthorized activity,” Next Level’s statement read. “If you notice any unauthorized activity, report it immediately to the relevant financial institution or credit bureau reporting the activity.”

Next Level said it’s taking steps to enhance its email security protocols and re-educating staff for awareness of best practices for keeping data secure.

“Your confidence and trust are important to us, and we regret any inconvenience or concern this incident may cause,” the company said. “If you have any questions, please call 855-551-1758, Monday through Friday from 9:00 A.M. through 6:00 P.M. PST.”

Incidents of cyber security breaches and cyberattacks are on the rise, both within promo specifically and in the broader marketplace.

With estimated 2020 North American promotional product revenue of $199.8 million, Next Level Apparel ranked eighth on Counselor’s most recent list of the largest suppliers in the industry.
