We can easily conduct searches on leaked credentials

We can easily conduct searches on leaked credentials. It gives us the ability to look at a timeline and build profiles against companies that we are trying to protect, then track changes to credentials or leaking bucket/cloud services associated with those companies. That is the benefit for us. A lot of it is stuff that we can do manually, but it is more about the time it takes as well as the number of analysts you need to do it compared to getting it provided as a quick service. It is scalable in that we don't need a dozen people to do the work. With this tool, one person can do it.

Has enabled me to reduce false positives and perform deep credential auditing with seamless integrations

I mostly use the configuration audit feature for the audit configuration as a scan policy, and I will use it for credential audit, which helps me scan credentials access such as local administrator or root access, performing a deeper and more accurate check of local configuration settings and file systems, making it a highly recommended feature. Regarding integration capabilities, we can integrate Tenable Nessus with SIM tools such as Splunk, IBM QRadar, and Azure Sentinel, as well as with ticketing systems such as ServiceNow, Jira, and Slack. There is no complexity as it is very easy to integrate everything. In terms of the reporting feature, while vulnerability scanning can throw some false positives, Tenable Nessus has very few, achieving a reduction of 75% to 80% false positives with manual analysis needed. We can generate standard Nessus reports that typically include host summaries and vulnerabilities by host and plugin, alongside solutions and remediation recommendations. The main benefits I get from Tenable Nessus are complete asset inventory and comprehensive attack surface management, allowing us to prioritize vulnerabilities based on risk, focusing on true risk and threat path analysis.

Quotes from Members

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

Pros

"If I conducted research manually it would take one week, but by using Sixgill it takes two hours or three hours."

"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."

"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."

"Rather than hiring more analysts, we have been able to do more with less and automate some of our investigation functions."

"The size and scope of the solution’s collection is amazing, and when we compare what other solutions can and cannot do, we see how Cybersixgill Investigative Portal is superior in many ways."

"I have been very vocal about how much this tool has helped."

"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."

"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."

"Nessus has more plugins/add-ons, tests, and templates than previous tools and it is faster and customizable using CLI/API features, offering enough resources for an interesting cost-benefit rating and fewer false-positive events per type of asset while helping us quickly produce a QuickWin report that guided vulnerability management actions and plans for the next three to five years using the same tool, investment, and team for all companies in the group."

"I would definitely recommend this solution; it's the best that I've used so far."

"The solution provides time saving and cost saving benefits."

"The most valuable feature of Tenable Nessus is the support it provides for any new vulnerabilities quickly."

"Vulnerability assessment is the most valuable feature in Tenable Nessus, as it provides brief details regarding the vulnerability issues we have in our network."

"I have experience with it on my attack stations, and it's pretty good to optimize. Personally, I think Nessus is quite a good product."

"The most valuable feature of Tenable Nessus is real-time monitoring."

"Among the most valuable features are scanning for vulnerabilities and the reporting. The reporting templates are okay. I like that I can see all the hosts with different vulnerabilities."

Cons

"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."

"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."

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

"The breadth of access to data is good, but there are gaps."

"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."

"Lacks some penetration testing-related services."

"They could make their reporting a little better."

"Tenable Nessus application device assessment is one of the top tools. However, in the application security assessment, there are other tools that provide better, and more accurate findings."

"Some things in the user interface could be better. The user interface could allow more adjustments to plugins. The price could also be better."

"This is still a maturing product. Tenable is only a scanner for one ability, while other solutions like Rapid7 have more tools for verification. We still have to manually verify to see if the vulnerability is a false positive or not."

"I think the reporting templates could be improved with Tenable Nessus."

"Tenable Nessus is very costly compared to OpenVAS and sits on the higher side."

"From my point of view the solution basically is not for the big enterprise."

Pricing and Cost Advice

"Sometimes, Cybersixgill Investigative Portal is cheaper than its competitors."

"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."

"It has a fair cost and very good cost-benefit ratio."

"We paid about six thousand dollars per license."

"The price of Tenable Nessus is too expensive for each service center."

"Nessus is affordable, but its licensing model could be improved with more flexibility for adding assets."

"This solution is affordable."

"The price of Tenable Nessus could improve, it is expensive."

"The price is okay. I would give it a seven out of ten, where one is cheap and ten is expensive."

"The newer tools are quite pricey. There is a case of some fine tuning that can be done in terms of licensing. The IP based licensing that is offered makes the tool very expensive. If they want the IT industry to adopt it, the price should be looked at."
