12 Best Spy Agencies in the World [As of 2019]

An intelligence agency essentially works like a nervous system in any nation’s defense setup, which is responsible for feeding vital information to law enforcement agencies and armed forces about possible threats to the national security. They collect, analyze and exploit secretive information that is not available to common people to their own advantage.

These agencies gather information by various means, including espionage, signal gathering or intercepting, cryptanalysis and various other methods. For those who don’t know, almost every nation has more than one operational secret service or spy agency, but mostly one stands out of the rest.

So what makes one spy agency better than another? Is it because of a colossal budget or relentless and hard training or it’s just because of the technology they use? Well, actually it’s a mixture of all these things. Anyway, here are 12 best spy agencies in the world.

  • There is only one Intelligence Agency in this world which is ‘ISI’ while other are school security guard level….The fear everyone can see people are even frighthened to Call or write ‘ISI’ because they are in a fear if they call or write this word they will pissoff in trouser.

  • Lol shit

    America is Asking to Pakistan for help them in Afghanistan
    Lol Everyone knows ISI on top….
    And IN SHA ALLAH till end it’ll remain on top..

  • There is only one Intelligence Agency in this world which is ‘ISI’ while other are school security guard level….The fear everyone can see people are even frighthened to Call or write ‘ISI’ because they are in a fear if they call or write this word they will pissoff in trouser.

  • While compiling data for the ranking, I think you people have forgotten to enlist ISI, Pakistan. The most powerful and active offensive intelligence agency of Pakistan engaged in Afghanistan and across the country to counter threats and challenges to national security. ISI has most of the time been at the top of the list.

  • shame on you… ISI remains always top so that is why isi is now the boss ,
    here ranking is just between other agencies

  • don’t know why everyone’s looking for isi, they got beat by the KGB, and missed undercover operators for the bin laden raid. They didn’t even properly check a company they were working with, and lost to the Indian military.

  • Mr. John, if you have not proper information, dont talk.
    Isi is the only agency which maintain its legacy and never beaten by any one other.
    Isi co-operate with cia then they found bin laden.If isi not do this, cia will never be able to find bin laden.
    Recently, it was isi which has a great role against indian threats.Due to information given by isi, pak air force was able to successful air strike on india and india gets huge loss.

  • I am not surprised by the ranking, in fact I was not expecting ISI Pakistan when I realize the author is an indian. Moreover, put raw at no 1 position and celebrate. We don’t want your approval to stay at the top. We are the best and world knows that. #PakistanZindabad
