Featured Reviews

Israel Cavazos Landini - PeerSpot reviewer
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.
HarshBhardiya - PeerSpot reviewer
Provided increased visibility across the organization's servers
The user interface of Tenable Nessus feels outdated and could be more user-friendly. Additionally, the documentation is not well-organized, which can be confusing when searching for solutions or specific information related to Tenable Nessus Professional. The reporting feature could be improved by allowing users to create their own templates instead of relying on predefined ones.
OndrejKOVAC - PeerSpot reviewer
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

"Zafran is an excellent tool."
"Zafran has become an indispensable tool in our cybersecurity arsenal."
"We are able to see the real risk of a vulnerability on our environment with our security tools."
"Once you get past the initial implementation, the solution is very stable."
"The features of Tenable Nessus that I have found most valuable are its reliability and its ability to collate a dependable output, where we are able to get the same vulnerability when we test manually. The output is quite reliable."
"The solution is the most dynamic one I have seen thus far."
"It is a mature tool."
"The most valuable features of Tenable Nessus include its ease of access and quick usability."
"Its initial setup was simple and straightforward."
"I find the features that are most valuable are the policies that help us identify the vulnerabilities. These policies are then used for scanning instabilities and then identifying the particular vulnerabilities."
"The most valuable feature of Tenable Nessus is the support it provides for any new vulnerabilities quickly."
"The initial setup process is simple."
"The scanning part, the agent part – that's the valuable aspect."
"Compared to other products, the most valuable features of the solution are its ease of use and ability to provide visibility over scan results while providing many templates to users, making it a helpful tool."
"The most valuable features of Tenable SC are the reports and the dashboards."
"We really love the Security Center dashboard. It basically performs vulnerability scanning and then outputs a vulnerability data."
"The tool gives us fewer false positives. Compared to its competitors, the solution’s reports are more accurate."
"The most valuable feature of this solution is the vulnerability assessment."
"The valauble feature is compliance reporting system."
 

Cons

"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 reporting feature needs to be improved."
"The pricing point has increased significantly in recent years. The product's pricing has roughly tripled within the last couple of years, making us reconsider renewing the license for the scanner."
"They need more flexible pricing."
"EQA's and dashboards should be addressed in the next release."
"We have had some false positives in the past, which we hope can improve in the future."
"They should try to create an all-in-one solution."
"Remediation needs improvement."
"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."
"Tenable SC could improve by making the creation of the initial reports easier that correspond to our network."
"We would like to see the inclusion of external IPs and simplified reporting that's easier to deal with"
"The solution needs to improve its support. I would like to see a bird's eye view of my network architecture. I would also like to see the continuous view feature in the tool."
"The web application scanning area can be improved."
"I think the vendor training provided for Tenable.sc could be a lower price. It's quite expensive for the training."
"The biggest issue I have with the solution is when I'm using the scanning it picks up the original DNS of that device. That means, before we image it and actually change the DNS to something within our company structure, it'll just be random numbers and letters and Tenable will stick to that DNS for a long time."
"A good plugin editor would be a good additional option for the Security Center."
"Additional costs are associated with using the solution, as additional scanners are required for different endpoints connected to the Tenable Security Center. If Tenable Security Center could extract information from these scanners automatically rather than manually, it would enhance user-friendliness for customers."
 

Pricing and Cost Advice

Information not available
"We paid about six thousand dollars per license."
"While Tenable Nessus is a good enterprise solution, the high price would likely make it prohibitive to smaller organizations."
"This solution is affordable."
"We incurred a single cost for a perpetual license, although I cannot comment on the price as this is above my management level."
"The price of Tenable Nessus is too expensive for each service center."
"Our organization is huge so our license costs $30,000."
"The price of the solution is reasonable."
"I think the price is fairly affordable. It provides a license that is fair."
"It is a bit expensive. Everything is included in the license."
"It is slightly more expensive than other solutions in the same sphere."
"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."
"The tool costs around 15,000 Saudi riyals monthly."
"We're happy with the licensing cost and find it affordable."
"I use a local license to perform penetration testing and I'm pretty happy with everything when it comes to pricing and licensing."
"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"
"The licensing costs for this solution are approximately $100,000 US, and I think that covers everything."
