Weekly insights and risk analysis facilitate informed security decisions
I appreciate the weekly insights Zafran provides, which include critical topics for networks and IT security, allowing us to evaluate which insights apply to our environment. The organization score feature is valuable to keep the leadership team updated on how our infrastructure fares security-wise. The applicable risk level versus base risk level feature is beneficial because prior to Zafran, we only used the base risk level, but now understand that risk depends on the asset itself. Zafran is an excellent tool.

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.

Empower clients with risk-based vulnerability management through continuous workflow and valuable insights
Tenable Security Center could improve by implementing more dynamic data displays and translating reports into European languages. This is especially relevant in Central Eastern Europe, where clients often require reports in local languages. Additionally, the licensing model could be more flexible for managed security providers, similar to a pay-as-you-go model.

Quotes from Members

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

Pros

"We saw benefits from Zafran Security almost immediately after deploying it."
"Zafran is an excellent tool."
"We are able to see the real risk of a vulnerability on our environment with our security tools."
"Overall, we have seen about eighty-seven percent reduction of the number of vulnerabilities that require urgency to remediate, specifically the number of criticals."
"Zafran has become an indispensable tool in our cybersecurity arsenal."
"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."
"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 most valuable feature of the product is the Assurance Report Card, which gives us an overview of the security poster in just a simple glance."
"Overall, I rate the solution 9.8 out of 10."
"The most valuable features of Tenable SC are the reports and the dashboards."
"This product has the best results in terms of the lowest number of false-positives and false-negatives."
"The most valuable features of Tenable SC are scanning, reporting, dashboards, and automation."
"Tenable.sc is user-friendly."
"The tool's dashboard and reporting capabilities match our company's needs since we are able to modify the basic view to create a new dashboard, and it works out very well for our needs."
"The most valuable feature is the automatic and periodic management of security scans, along with the ability to consolidate all information into a single dashboard."
 

Cons

"I think the ability to have some enhanced reporting capabilities is something they can improve on, as they have good reports but we have asked for some specific reporting enhancements."
"Initially, we were somewhat concerned about the scalability of Zafran due to our large asset count and the substantial amount of information we needed to process."
"The dashboarding and reporting functionality of Zafran Security is an area that definitely could use some improvements."
"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."
"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."
"The vulnerability scan does not work correctly until the access privileges are set by the system administrator."
"Security can always be improved."
"The solution is expensive."
"The pricing is reasonable, but this could be brought down more aggressively, such as we see with Rapid7, Tenable SC's main competitor."
"The reports and plugins for reports and scans could benefit from enhancements."
"Tenable SC can improve by making it easier to create complicated reports and have more effectiveness in the remediation area for comparison between the scans."
"The solution needs to improve the vulnerability assessment because we have experienced some challenges with accuracy."
"A good plugin editor would be a good additional option for the Security Center."
 

Pricing and Cost Advice

Information not available
"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."
"The pricing is cheap compared with Recorded Future. Sixgill's cost-effectiveness is very good."
"The tool provides competitive pricing."
"Tenable SC is priced per asset, with the basic solution starting around US$12,000 for 500 assets."
"My company needs to make yearly payments towards the licensing costs. The pricing of the solution falls in the mid-range level, so it is not too expensive"
"Tenable is open-source."
"Tenable.sc is more expensive than its competitors."
"The price of Tenable SC is expensive, we pay approximately €70,000 for the license annually. We have to pay for each IP test. The cost of other solutions is far less, such as Nessus Professional, which is €3,000 annually."
"For 500 users the licensing fee is roughly $100,000."
"We're a Fortune 500 company... our licensing costs [are] in the seven figures."
