JPCERT/CC is an organization that coordinates the activities of CSIRTs and other related organizations to report computer security incidents and vulnerability related information. Acting as the national CSIRT of Japan, JPCERT/CC coordinates between domestic and international CSIRTs and related organizations to manage incidents that require international coordination.
To improve the level of computer security domestically, JPCERT/CC collects incident reports from various sources such as product developers, vendors, and users; assesses and analyzes how incidents occurred; and provides support for incident response including attacker profiling. The results from the assessment and analysis are published as countermeasures. The goal of these activities is for the user to implement these countermeasures and prevent cyber attacks by making it increasingly difficult for attackers.

With respect to security, a global perspective is required as the entire world is highly interconnected via the Internet. JPCERT/CC has been involved in the administration of FIRST, the international forum of CSIRTs, as a core member, exchanging information with about 200 CSIRTs in 41 countries.
In addition, thanks to partnerships with the United States' CERT/CC and the United Kingdom's CPNI for vulnerability related information coordination, as well as collaboration with China's CNCERT/CC, Korea's KrCERT/CC and CSIRTs of other countries, JPCERT/CC has strengthened its relationships with those organizations.
