The solution’s approach of using limited open source intelligence and focusing, instead, on the Deep Web and Dark Web is what seals the deal. That is why I like them. I have other tools that I can aggregate all the open source intelligence from. I value Cybersixgill because it provides access to things that no one else does.

To be diligent for the customer, we usually go into Cybersixgill Investigative Portal to analyze and search things. The solution tells us the reputation of cyber threat actors. So, if someone has a reputation of one, it is a really bad idea to care about what that person is saying. However, if you find someone with a reputation of nine, then there is a high probability that we need to address the problem. You can get information about these type of actors in Cybersixgill Investigative Portal. They have a huge collection, which is like having the rules/goals of the dark web and deep web without having to go there. Our analysts avoid going dark web because they have Cybersixgill Investigative Portal and can get the news from their browser, searching wherever they want.

They also provide some of the greatest notification capabilities. I put in a customer's company name and domain names, or sometimes I put in their IP addresses as a keyword. Once Sixgill collects information that includes those keywords, they then provide us email notifications. That means we can catch information related to our customers as soon as possible.
 

Cybersixgill Cons review quotes

Aug 24, 2026
I think the way they can be improved is to be able to initially during the onboarding, make sure that the false positives are correctly addressed to really do the tweaks that need to be done to filter through exactly what the organization is trying to accomplish and give them the outcomes they are looking for without all the extra noise or chatter.

I want to highlight that sometimes Cybersixgill retrieves leak information from the past two years, which can be very irrelevant to the client.

The breadth of access to data is good, but there are gaps. More data would be my suggestion because the platform is good and I have no complaints about the system. I think it is just a case of always trying to get more data sources.

Regarding their scraping abilities, things could be solidified. There are definitely improvements that could be made on the specificity for setting certain queries.

We need real-time updated information. If we could have this, it would be amazing. For example, if someone was posting something, then ten second later, it was on the platform. Sometimes, it takes a minute or hours right now, depending on the forum.

Sixgill has strong capabilities based on search queries, but there is some difficulty in using Sixgill. Their querying is very powerful but it can be difficult. It's not hugely complex but you need some skill to use Sixgill querying.
