About HIRT

HIRT (Hitachi Incident Response Team) was established in 1998 as an in-house project, and was organized to act as CSIRT (Computer Security Incident Response Team) for the Hitachi group in October 2004.
To promote better vulnerability handling (support activity to eliminate security vulnerabilities) and better incident responsiveness (support activity to avoid and recover from the latest security violations and related incidents), HIRT is the CSIRT point of contact (PoC) that coordinates the Hitachi group and liaisons with external entities, in line with "Information Security Early Warning Partnership Guidelines".

Also, in January 2005, HIRT joined FIRST, the international CSIRT forum.
