TJX uses AI tools to help detect fraud and identify cybersecurity threats across its store and payment systems. The company confirmed in November 2025 that this is one of the active areas where AI is being deployed, working alongside its existing security team.

JX operates a Security Operations Center (SOC) led by a Chief Information Security Officer, and the company has invested heavily in security infrastructure since a major payment card breach in 2007 that affected tens of millions of customers. As of fiscal year 2025, TJX's annual report acknowledged that cyberattacks are growing more sophisticated through the use of AI — signaling the company is building defensive AI capabilities in response. CEO Ernie Herrman described fraud detection and security as one of five confirmed areas where AI is being tested and deployed, characterizing the approach as augmenting the work of security associates rather than replacing them.
