The National Technical Research Organisation (NTRO) is an Indian technical intelligence agency. Since its inception in 2004, the agency has often been the subject of national controversy.
The NTRO acts as the primary advisor on security issues to the Prime Minister and the Union Council of Ministers of India. It also provides technical intelligence to other Indian agencies.
NTRO's activities include satellite and terrestrial monitoring. It cannot, however, legally monitor Internet or other communications; there are nine other agencies authorized to do so. NTRO is also charged with developing technology relevant to Indian national security and intelligence. These technologies include cryptology, cybersecurity and data management.
