Provides early detection of imminent attacks, and speeds up addressing of vulnerabilities internally because it makes them real
They're a newer company, so they're working on their UI a lot. Sometimes the UI is a little glitchy. They're working on different things and making efforts, so that's totally forgivable. But regarding their scraping abilities, things could be solidified. There are definitely improvements that could be made on the specificity for setting certain queries. Step-by-step videos would be useful, instead of a book of instructions, because they're a new tool. They're now getting to the point where video training would be useful, or even live training. More digestible video instructions or opportunities for training, so that you actually learn hands-on, would help.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"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."
"The advanced analysis has made our security operations more efficient. It has also potentially given us quicker access to data that we might not have otherwise located."
"The anti-spam features are excellent on the email firewalls."
"It's the top choice because no company can operate without security. Ensuring email protection is a major priority for any organization when building its infrastructure."
"Proofpoint provides an expandable project model, including DLP, email archiving, and encryption, which makes it a complete email security solution."
"The solution blocks malicious emails containing viruses and malware and reduces them out of spam."
"The solution's technical support is good. I rate the technical support a ten out of ten."
"I like all the features with Proofpoint, such as how it filters the spam and marketing mail, lost reality mail, blocks phishing attacks, blocks malicious attachments, and stops phishing links. Also it can defend against the business email compromise impersonation technique. It is a complete solution for all email attacks. It filters for the bad, malicious attachments. If there is any executable file, it can be deleted. It is a good, complete solution."
"They have customized security rules, mature rules, anti-virus protection, as well as email authentication similar to SPF, DKIM, and DMARC."
"It's very good at identifying threats."
 

Cons

"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."
"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."
"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."
"In terms of improvement, the price could be better. Additionally, more security could be implemented."
"The product's deployment is complex and requires technical knowledge."
"The Secure Mail aspect should have an Outlook add-in, instead of an external dashboard that outside users have to access."
"Unfortunately, the whole product is going downhill right now, ever since they were sold to Thoma Bravo. We're constantly having problems with stability and the product in general."
"The solution should add post-sales training."
"It became very expensive due to the nature of local circumstances, and I may advise Proofpoint to adjust marketing solutions based on each country."
"The solution could lower its price."
"Proofpoint Email Protection could improve by allowing more customization of the reports, such as exceptions and black-and-white lists."
 

Pricing and Cost Advice

"The pricing is cheap compared with Recorded Future. Sixgill's cost-effectiveness is very good."
"The pricing and licensing are good. It is expensive for us because the US dollar is quite strong compared to our dollar. Otherwise, it is quite reasonable for what it is. All the tools in the market are around the same price from my experience."
"Sometimes, Cybersixgill Investigative Portal is cheaper than its competitors."
"Proofpoint is fairly expensive."
"Proofpoint Email Protection has comparable pricing."
"The licensing model for Proofpoint Email Protection is simple. It's based on the number of users. Price-wise, Proofpoint Email Protection is a five out of ten because it's a pretty expensive solution."
"Pricing has recently been increased and the cost is a downside"
"I rate the product price a seven on a scale of one to ten, where one is low price and ten is high price."
"We sell annual licenses for this solution."
"The solution is expensive."
"The price is reasonable."
