CERT-In is a low-profile (Indian) government organization.
The Government of India established the Computer Emergency Response Team (“CERT-IN”) to ensure Internet security. Many institutions, including the Ministry of Home Affairs, courts, the intelligence services, the police, and the National Human Rights Commission, may call on it for specialist expertise. CERT-IN’s stated mission is “to enhance the security of India’s Communications and Information Infrastructure through proactive action and effective collaboration” [Source]
I had a chance to visit CERT-In last week. The experience was overall good, unlike the typical dirty government office with laid-back employees, I saw employees enthusiastic about their work (and a colorful office).
