CSC’s Domaincasting offers threat vector data (including phishing and brand attacks) from global partners as well as the unique data associated with their domain portfolios. This enables our clients to neutralize attacks simultaneously while enforcement actions are being taken.

Domaincasting’s data partners include global internet service providers (ISPs), security providers, browser carriers, security information and event management systems (SIEMs), telecom providers, registrars, web hosting providers, and law enforcement agencies. CSC shares Domaincasting data via multiple network protocols and applications including email, application programming interface (API), and other secure data exchange methods.
