FireEye’s past clients have included Deloitte, Equifax, the New York Times, Cathay Pacific, Target, Uber and Yahoo. Most famously, it helped Sony Pictures investigate a ruinous 2014 cyber attack which it eventually attributed to North Korea.

Like many cybersecurity companies, FireEye routinely "red teams" its clients’ systems, executing controlled attacks with permission in order to expose their flaws.
