The Research and Analysis Wing, commonly known as RAW, is India's primary external intelligence agency. Established in 1968, RAW's primary objective is to gather strategic intelligence from foreign countries and counter potential threats to India's national security. Operating under the purview of the Prime Minister's Office, RAW remains shrouded in mystery, functioning discreetly on a global scale.

With a strong network of assets and informants, RAW plays a vital role in analyzing geopolitical developments, monitoring neighboring countries, and providing essential insights to the Indian government for informed decision-making.

Intelligence Bureau (IB)

The Intelligence Bureau, abbreviated as IB, is India's oldest and leading domestic intelligence agency. IB department started its operation from1887 under the Ministry of Home Affairs. Unlike RAW, IB's primary focus lies in countering internal threats, such as terrorism, insurgency, and other subversive activities.

IB conducts extensive surveillance, monitors extremist groups, and collects intelligence on activities that pose a threat to India's internal security. Its decentralized structure allows it to maintain a strong presence in various states and Union Territories, enhancing its effectiveness in safeguarding the nation from within.

Central Bureau of Investigation (CBI)

The Central Bureau of Investigation, better known as CBI, is the premier investigative agency in India. Founded in 1941 as the Special Police Establishment, it was later rechristened as the CBI in 1963. Functioning under the jurisdiction of the Ministry of Personnel, Public Grievances, and Pensions, the CBI is responsible for probing and solving complex criminal cases, including corruption, economic offenses, and high-profile cases that have national ramifications.

As an independent investigative body, the CBI often works in collaboration with other agencies, including state police forces, to ensure comprehensive and unbiased investigations.

National Technical Research Organisation (NTRO)

In the digital age, intelligence gathering has transcended traditional methods. The National Technical Research Organisation, or NTRO, was established in 2004 to address the emerging challenges of cyber warfare and technical intelligence. Operating under the oversight of the National Security Advisor, NTRO employs cutting-edge technology to intercept and monitor communication signals, including satellite communications and cyber activities that may pose threats to India's security.

Defense Intelligence Agency (DIA)

The Defense Intelligence Agency, commonly known as DIA, was formed to meet the specific intelligence needs of the Indian Armed Forces. Established in 2002, DIA serves as the principal agency for military intelligence, enabling effective planning and execution of defense operations.

DIA collaborates with other intelligence agencies and keeps the military leadership informed about potential threats, enemy activities, and emerging security challenges. This coordination ensures that the Indian Armed Forces are well-prepared and equipped to safeguard the nation's interests.

Aviation Research Centre (ARC)

The Aviation Research Centre, also known as ARC, operates as the aerial intelligence-gathering arm of RAW. Established in 2002, ARC is responsible for conducting aerial reconnaissance missions in neighboring countries and other areas of interest.

Equipped with state-of-the-art aircraft and surveillance technology, ARC plays a crucial role in obtaining critical information from remote and sensitive regions, supporting India's strategic interests.

Special Frontier Force (SFF)

The Special Frontier Force, or SFF, is a unique paramilitary force established in 1962. Comprising personnel from the Tibetan community, the force operates under the intelligence agencies and isprimarily deployed in remote and challenging terrains, especially along the Sino-Indian border.

SFF's operations and missions are highly classified, and their members are trained in specialized warfare techniques to counter threats in the border regions.

National Investigation Agency (NIA)

The National Investigation Agency, abbreviated as NIA, is the central counter-terrorism law enforcement agency in India. Established in 2009, NIA deals with terror-related cases and conducts investigations across the country to counter the growing menace of terrorism.

NIA has played a crucial role in dismantling terror networks, preventing attacks, and bringing terrorists to justice through its diligent and meticulous investigative efforts.


The secret agencies in India form the backbone of the nation's security apparatus, operating silently and relentlessly to protect its interests. While their operations often remain veiled from the public eye, their significance cannot be overstated in safeguarding the nation from various threats.

From the Research and Analysis Wing's strategic intelligence gathering to the Intelligence Bureau's internal security measures, and from the Central Bureau of Investigation's fight against corruption to the National Technical Research Organisation's cyber expertise, each agency plays a crucial role in maintaining India's sovereignty.

In an ever-evolving world, these agencies continue to adapt to new challenges, ensuring that India remains prepared to defend itself from both conventional and emerging threats. Their dedication, professionalism, and commitment to national security are a testament to their indispensable role in the country's journey towards progress and prosperity.
