San Francisco cybersecurity firm Cloudflare’s services protected three child-sex-abuse websites for years, according to a new report.

The company, which sells website performance, reliability and security services, shielded the three sites from identification despite being notified by the National Center for Missing and Exploited Children about abuse imagery on the sites, according to the report Monday in the New York Times. The sites have since shut down.
