FAQ - what is a private intelligence service?

  • How does a private intel service operate?

    An intelligence services has 3 main objectives: -obtaining information -analyzing information -keeping other parties from accessing protected information. There are specific methods for each of these areas - some are overt, some covert, some technical, some undercover, some even long-term deep cover missions. It is a well-known fact that espionage is happening on all kinds of levels all the time - governments, competitors, criminal organisations, terror groups, even the VATICAN is conducting espionage (in fact, the latter has the oldest still operating intelligence service in the world...). If you are doing business, chances are that someone are conducting espionage against your company RIGHT NOW. Corporate espionage has become a "NORMAL THING". Even your own social media app are spying on you! Depending on your kind of business, the threat is immense. We have the wherewithall, the experience and the network to support, assist and protect you on any level.

  • Who really needs a private intelligence service?

    Well, in fact ANYONE conducting any kind of serious business or any kind of security operation needs intelligence (or information). You cannot be successful long-term without up-to-date, correct info about your market, your company, your own security service, your competitors. And the world and the markets change constantly, a business owner usually doesn't have the expertise or the time to handle the information business. Experts are the right solution. Security teams need intel just as much, if you do not KNOW the threat in all details, you will always be one step behind the opponent. Market research, for instance, is a form of intelligence gathering. Knowing exactly WHO is your competitor is just as important as REALLY knowing your key staff. The world being as it is, the threats are coming from so many sides today; the business of the unprepared will suffer eventually.

  • Is a private intelligence service even legal?

    Yes, absolutely. Intelligence experts operate within the law, just like lawyers or investigators. Of course there are limits, just like for investigators, but there are also specific methods of obtaining information that regular investigators may not or cannot use, that require a special finesse, experience and training. This concerns both the acquisition of intel, as well as the protection of the client's assets. Another field of expertise is the analysis and corroboration of intel. All these actions are fully within the law. Our team will never expose our clients to another legal problems.

  • What is intelligence brokering or information brokering?

    Certain companies specialize in brokering information. These entities research a number of "sources" in order to find needed info for their clientel. Some of such information is openly available, and other information must be actively obtained by use of various means. Information YOUR business needs may very well already be available in the databanks of such brokers. Information brokering might be a faster way instead of trying to find information by means of investigation etc. On account of our network - the Brillstein Security Group has been operating in the field of private intelligence for about 35 years on an international level - we have not only the experience but a large network and connections to the right kind of experts worldwide at our disposal. The information you may need most probably already exists somewhere. Due to our longstanding connections, we can approach such experts and obtain qualified intel for our clients. This is being called information brokering. This process can considerably shorten the time needed to get the information required.

  • How much does an intelligence service cost?

    It is near impossible to answer that question generally. It all depends on the exact service needed, what kind of actions are necessary etc. Informations are the most valuable asset of any business, or any enterprise of any kind, and any government for that matter. Certain information are very hard to get. It may take a lot of time and effort. However, NOT obtaining the info your business needs, or NOT protecting your business against the various forms of espionage and threats is CERTAINLY much more costly...
