Top 10 Intelligence Agencies In The World 2021

We are constantly hearing about the three-letter agencies – MI6, CIA, FBI, NSA but do we understand what they do and how they impact the lives of citizens?  Do you know which one is the top intelligence agency in 2021?

In the following article, I explain to you the importance of intelligence agencies, their main tasks and a top 10 of the best intelligence agencies in the world in 2021.

The importance of intelligence agencies

Intelligence agencies are mandatory for the security and the prosperity of a country.

In most of the states, intelligence agencies are classified in two main categories: internal security intelligence and foreign intelligence.

The internal security intelligence agencies take care of the security on the homeland taking care of domestic threats like bioterrorism, terrorism or espionage.

The foreign intelligence agencies are busy with activities like information collection relating to the political, or economic activities of foreign states.

It’s important to know that all foreign intelligence agencies are active in other countries where they don’t have any protection of the law and have to work clandestinely.

If I take as an example the United States, FBI is the homeland intelligence agency while the CIA is taking care of US interests in all other states.

What are the tasks of an intelligence agency?

The Intelligence agencies of any country can provide the following services for their national governments:

  • gathering intelligence through various means (open sources like social media, online newspapers etc.)
  • conducting various forms of espionage
  • advising the government on matters related to national security
  • Protect sensitive information secrets, both of their sources and activities, and those of other state agencies;
  • Defence against the efforts of other national intelligence agencies (counter-intelligence).

While all the intelligence services of the world nations are best in their regard, some are superior to others in the execution of their missions.

Wait no more, here is our top 10 powerful intelligence agencies around the world.

Headquartered in Shahrah-e-Soharwardi in Islamabad the Pakistani agency was at the heart of a large number of scandals, especially caused by India, which accused them of encouraging terrorism by supporting militant and smuggling groups.

Its is believed to have the highest number of agents worldwide, close to 10,000. The most striking thing is that it’s one of the least funded Intelligence agency out of the top 10.

Note about the Mossad HQ: An apparent former Mossad agent claimed to have revealed its location in at a highway intersection called Glilot Junction in 1987. In journalist Patrick Tyler’s 2012 book Fortress Israel, he located Mossad’s headquarters as a “partially hidden campus of low-slung office buildings sandwiched between the Glilot highway junction, a Cineplex, and a shopping centre.” The buildings seen above appear to fit the location and description

The most famous division of Mossad is the “Special Operations Division” called Metsada, was involved in many assassinations and operations around the world.

Update: If this news about the health ministry that says Mossad bought wrong testing kits for coronavirus is proved to be real we will have to downgrade Mossad a couple of places.

The CIA specializes mainly in foreign affairs, with very few responsibilities in terms of internal policy and responds directly to the President of the United States. Its basic functions include searching for and analyzing information about foreigners and operations that concern the President.


It was difficult to create a top of intelligence/espionage agencies because of the fact most of the successes of these agencies remain secret and are declassified after 50 years, or the general public never founds some out.

That’s why we took a close look at the security and prosperity of the countries and intelligence-gathering operations from open sources like digital newspapers and books.
