India has a complex and multi-layered network of intelligence agencies designed to protect its national security, strategic interests, and critical infrastructure. At the national level, agencies like the NTRO operate under the PMO and focus on technical, scientific, and strategic operations. NTRO specializes in electronic, aerial, and technical surveillance to monitor external threats and provide actionable insights. Similarly, the R&AW handles operations outside India, gathering information from human sources, communications, and open sources. Specialized wings like the ARC conduct aerial reconnaissance, while the ETS and RRC focus on technical and signals monitoring.^[1]

Within India, internal security is managed primarily by the IB, which works on counter-intelligence, counter-terrorism, and maintaining law and order using human, electronic, and open-source reporting. Agencies such as the NIA deal with terrorism and organized crime, while the CBI and NCB handle criminal investigations and drug-related activities. Cyber threats are addressed by the Indian Cyber Crime Coordination Centre, which monitors online crime and ensures the security of digital networks.^[2][3]

The Ministry of Defence and Ministry of Finance host several other important agencies. The DIA coordinates with the Directorate of Military Intelligence, Directorate of Naval Intelligence, and Directorate of Air Intelligence to support the armed forces and maintain national defense readiness. Financial oversight is provided by agencies such as the ED, FIU, and Central Economic Intelligence Bureau, which focus on money laundering, tax evasion, and terrorism financing. Technical and communication monitoring is reinforced by the TERM and the National Cyber Coordination Centre, ensuring India can track both conventional and digital threats effectively.^[4][5]

The National Technical Research Organisation (NTRO)^[6] is a technical intelligence agency under the National Security Advisor in the Prime Minister's Office, India.^[7] It was set up in 2004.^[8] It also includes the National Critical Information Infrastructure Protection Centre (NCIIPC) and the National Institute of Cryptology Research and Development (NICRD) for cryptologic education and research, which is first of its kind in Asia.^[9]

Research and Analysis Wing (R&AW) is the primary foreign intelligence agency of India. The agency's primary function is gathering foreign intelligence, counter-terrorism, counterproliferation, advising Indian policymakers, and advancing India's foreign strategic interests. It is also involved in the security of India's nuclear programme.

The Aviation Research Centre (ARC) is a part of the Research and Analysis Wing (R&AW) of the Cabinet Secretariat (Special Requirements) India. The first head of the ARC was R. N. Kao, the founding chief of R&AW. Over the years the ARC has grown into a large operation and flies a large and varied fleet. Aerial surveillance, SIGINT operations, photo reconnaissance flights (PHOTINT),^[10] monitoring of borders, imagery intelligence (IMINT)^[11] are the main functions of the Aviation Research Centre (ARC). The aircraft are fitted with state-of-the-art electronic surveillance equipment and long range cameras capable of taking pictures of targets from very high altitudes. ARC also takes the responsibility along with the IAF to transport Special Frontier Force (SFF) commandos from their trans-location at Sarsawa, 250 km north of New Delhi, though the SFF's own base is in Chakrata in Uttarakhand state.

The Radio Research Centre (RRC) is a part of the Research and Analysis Wing (R&AW) of the Cabinet Secretariat (Special Requirements) India. The RRC is a premier communication and signal intelligence agency of India. RRC's tasks include – communication with the embassies abroad, send cyphered code to agents stationed abroad, interception fixed line and wireless communication and the department closely works with the Joint Cypher Bureau. The RRC has offices all across the country and the perform the intercepts communication and sends code.^[12]

The Electronics and Technical Services (ETS) is the Electronic Intelligence (ELINT) arm of India's external intelligence agency Research and Analysis Wing (R&AW). Established in the mid-1980s under the leadership of then R&AW's chief N. F. Suntook, the organisation, it is housed in the CGO complex in New Delhi. ETS is believed to be involved in ELINT roles, not restricted but also includes jamming and spoofing - Electronic Warfare (EW). ETS also involved in Electronic Surveillance Measures (ESMs), Telemetry (TELINT), Tracking and monitoring data links, interception and monitoring of navigation signals and other ELINT and EW methods.^[13]

The Intelligence Bureau (IB) is India's internal intelligence agency.^[14] The Intelligence Bureau (IB) (Hindi: आसूचना ब्यूरो; IAST: āsūcanā byūro) is India's domestic internal security and counter-intelligence agency under Ministry of Home Affairs. It was founded in 1887 as Serval Intelligence Branch, and is reputed to be the oldest such organization in the world.

The National Investigation Agency (NIA) is the principal counter-terrorismlaw enforcement agency in India. Established under the National Investigation Agency Act, 2008, it is tasked with investigating and combating offenses related to national security, terrorism, and other threats affecting the integrity and sovereignty of the nation. It operates under the administrative control of the Ministry of Home Affairs, Government of India.^[15] The primary mandate of the agency is to investigate and prosecute offences that have national and cross-border implications, specifically focusing on insurgency, terrorism, and other related matters. It is empowered to investigate cases that involve threats to the integrity, security, and sovereignty of India.

It has the authority to conduct searches, make seizures and arrests without warrant, as well as to collect evidence and maintain a database of terrorist organisations and their members. The NIA does not need any type of authorization or permission from any state government in order to carry out its activities, unlike other national-level agencies.^[16][17]

The agency came into existence with the enactment of the National Investigation Agency Act 2008 by the Parliament of India on 31st December 2008, which was passed after the deadly 26/11 terror attack in Mumbai. Such an attack revealed the failure of intelligence and ability to track such activities by existing agencies in India, hence the Government of India realised the need for a specific body to deal with terror related activities in India, thereby establishing the NIA.^{[16][18][19][20]} Headquartered in New Delhi, the NIA has branches in Hyderabad, Guwahati, Kochi, Lucknow, Mumbai, Kolkata, Raipur, Jammu, Chandigarh, Ranchi, Chennai and Imphal.^[21] It maintains the NIA Most Wanted list. Its functioning and effectiveness have also been subject to scrutiny, with debates regarding its jurisdiction, accountability, and coordination with other agencies.

The National Cyber Coordination Centre (NCCC) is an operational cybersecurity and e-surveillance agency in India. It is intended to screen communication metadata and co-ordinate the intelligence gathering activities of other agencies.^[22]

The Directorate of Revenue Intelligence (DRI) is an Indian intelligence agency. It is India's apex anti-smuggling intelligence, investigations and operations agency. The DRI is run by officers from the Central Board of Indirect Taxes and Customs (CBIC) who are posted in its various Zonal Units as well as in Indian embassies abroad as part of the Customs Overseas Intelligence Network. It is headed by a Director General of the rank of Special Secretary to the Government of India.

The Defence Intelligence Agency (DIA) was established on 5 March 2002 with the appointment of Lt. General Kamal Davar as the first Director General (DG). The DG reports to the Chief of Defence Staff (CDS). It is supposed to be the nodal agency for all defence-related intelligence, thus distinguishing it from the R&AW. Much of the agency's budget and operations are classified.

DIA has control of MoD's prized technical intelligence assets – the Directorate of Signals Intelligence and the Defence Image Processing and Analysis Centre (DIPAC). While the Signals Directorate is responsible for acquiring and decrypting enemy communications, the DIPAC controls India's satellite-based image acquisition capabilities. The DIA also controls the Defence Information Warfare Agency (DIWA) which handles all elements of the information warfare repertoire, including psychological operations, cyber-war, electronic intercepts and the monitoring of sound waves. Before the creation of the Defence Intelligence Agency, the military intelligence capability of India's armed forces was limited to Field Intelligence Units (FIU) and separate intelligence arms of the services.^[28] These distinct services were not able to effectively coordinate intelligence operations and sharing of information.^[29] The armed forces also heavily relied on civilian intelligence agencies such as the Research and Analysis Wing and the Intelligence Bureau.^[28] With wide-ranging resources and functions, the DIA will be superior to and coordinate the Directorate of Military Intelligence, Directorate of Air Intelligence and the Directorate of Naval Intelligence.^[29]

The Signals Intelligence Directorate is a joint service organisation, composed of personnel from the Army, Navy and Air Force. It has a large number of Wireless Experimental Units (WEUs) that carry out the task of monitoring military links of other countries.

The Central Monitoring Organisation (CMO) is directly under the Ministry of Defence. It has several monitoring companies, located at different locations around the country. Task is to monitor the use of radio spectrum by all users, such as Defence, Police, AIR, Railways, PSUs, etc.

The Telecom Enforcement Resource and Monitoring (TERM), formerly known as Vigilance Telecom Monitoring (VTM), is the vigilance and monitoring wing of the Indian Department of Telecommunications (DoT).^[30] TERM is made up of 34 cells in India's 22 telecom circles and 10 large telecom districts. The main functions of TERM Cells are vigilance, monitoring and security of the network.^[31] Apart from this, TERM Cells also operate the Central Monitoring System (CMS), a clandestine mass electronic surveillance program, and carry out other functions.^[32]
