Sixgill Prevents Attacks from the Deep Web Before They Happen

People often think that the Internet ends where search results end – so, if they fail to find something, then that something probably does not exist. However, the Internet is really much more than search engines like Google, Bing and Yahoo! can display.

In fact, the results indexed by these search engines comprise only a small part of the Internet’s real size, and that is called “Surface Web” or “Visible Web”. That naming has a strong connection to an iceberg, where the visible part is really its smaller part, just like the representation below shows (which most people probably seen already):

The rest, the part that is “submerged”, corresponds to the “Deep Web“: the portion of the Internet that require specific methods to be accessed, and that is capable of providing some degree of anonymity for the users. Some studies estimate that this portion is 500 times greater than the Surface Web (which is speculated to comprise only 4 percent of everything there is on the Internet).

The use of the Deep Web is quite varied, and therein lies the controversy. Because of privacy, many people and institutions use it to share and host sensitive files and that may not be available in the “conventional internet.” The army, police, journalists and even ordinary citizens with some internet knowledge are examples of people using the Deep Web for specific purposes.

However, anonymity also allows the proliferation of a number of crimes and bizarre stuff, such as hacking, trading illegal drugs (where Silk Road is the most well-known example), organs, weapons and even humans, as well as child pornography and ordering assassinations, are just some of the examples. All this is what makes the Deep Web so scary and dangerous.

One important aspect of the Dark Web is that it represents the source of many cyber attacks and hacks, and the inherent anonymity makes it easy to exchange illicit information, as well as collaboration on criminal and terrorist plans. Due to the aforementioned anonymity and its fragmented nature, it is hard to get information about upcoming hacks or other attacks.

And this is exactly where Sixgill comes into action: this cyber intelligence SaaS startup that analyzes the Dark Web and recently announced its official public launch, solves this problem with its proprietary algorithms and technology that try to connect the dots of the Dark Web as thoroughly as possible, providing information that organizations can use to prevent attacks against them and their employees.


Sixgill aims to detect and prevent cyber attacks and sensitive data leaks originating from the Dark Web before they occur, sending real-time alerts to its clients. This is possible thanks to the use of automated monitoring of closed, open, and hybrid Dark Web forums where, using the powers of “big data” analysis, it creates profiles and patterns of Dark Web users and their hidden “social networks”.

With this, Sixgill can identify potential hackers according to their their activities, and track them as they plan their activities. Its clients receive information about such threats, which can give them time to prepare and reinforce their security measures. Avi Kasztan, CEO and cofounder of this company, explain what makes Sixgill unique in the digital security industry:

“Sixgill is the most innovative Dark Web intelligence platform and we’re leading the way in the first steps of cyber security, when the damage can still be avoided. We have created a team of top notch professionals from Israel’s elite intelligence units and companies with disruptive technologies, and the results speak for themselves. The funding will allow us to keep mastering and crawling the Dark Web while increasing our market share globally.”

The solution offered by this company is surely interesting, and promises to be very useful in the near future, especially since we live in a time where new threats, such as ransomware, are constantly appearing, and the Dark Web is a strong candidate to be the place of their inception.
