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The user interface of Tenable Nessus feels outdated and could be more user-friendly.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.
Shreevinayak Deshpande - PeerSpot reviewer
Makes vulnerability management efficient with a single pane of glass and daily report generation
There are areas for improvement. Initially, when onboarding Vulcan Cyber, the setup and configuration was more complex than expected with a user-friendly approach. This aspect can be enhanced. An important area is performance and speed, as Vulcan Cyber often lacks speed when exporting reports. The team might have to work on scaling up servers. When we click on a vulnerability, it takes ten seconds to pop up a window and show the entire content. Instead of that, they can put a down arrow, and all the details should be shown on clicking the arrow. This will prevent that ten-second delay. Another area for improvement is providing support and documentation for their tool. Users should have access to easy-to-understand trial documentation for reference.

Quotes from Members

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

Pros

"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 is an excellent tool."
"Zafran has become an indispensable tool in our cybersecurity arsenal."
"We saw benefits from Zafran Security almost immediately after deploying it."
"The automatic scanner and scheduler are pretty cool."
"The vulnerability scanner is the most valuable feature."
"The most valuable feature is how it scanned and detected through its database to let us know exactly what fixes we needed to put in place for the vulnerabilities. It detects and it also gives you the way to fix it."
"The reports are pretty nice and easy to understand."
"Nessus is effortless to integrate."
"The initial setup of Tenable Nessus is very easy."
"The trial version is very good for testing whether it will suit your needs."
"The most valuable features of Tenable Nessus are the scanning option. Advanced scanning is highly useful. The offline config audits and application assessments are useful."
"Now that the solution is onboarded, we are saving a lot of time. We're saving roughly four to ten hours a week."
"The interface of Vulcan Cyber is intuitive with a lot of information about vulnerabilities, which helps in classifying and analyzing threats. We have a good view of assets and vulnerabilities. It helps to do good threat analysis because we can see exactly what the threat is and assess it accordingly."
"It is very good when it comes to ingesting information from different sources and then displaying this information in an easy-to-use platform."
"One of the features that I find valuable is the ability to bifurcate the report according to the many options available."
"The most notable aspects include having prioritization capabilities and custom scripts."
"They recently upgraded their UI, which is great. It is user-friendly."
"There is a lot of flexibility in exporting, making it a really good feature. The exporting flexibility based on application type is commendable and provides significant value."
"Vulcan Cyber is a very good tool."
 

Cons

"The dashboarding and reporting functionality of Zafran Security is an area that definitely could use some improvements."
"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 user interface of Tenable Nessus feels outdated and could be more user-friendly."
"The report for counters is too simple and would be improved by a dashboard."
"Tenable Nessus could improve reporting and information sharing. It would be helpful if we could share the reports and have a little bit better flexibility in the reporting of the data."
"It wasn't very clear how the scripts are running the scans. There's information about the script but it's not straightforward. The script information for each of the plugins should be available, but it doesn't give us straightforward direct information about how it was executed. That needs to be more clear."
"I have found it is sometimes difficult to control the Zoom meeting sessions. For example, it is difficult to know who is talking and when trying to mute everyone but the speaker you end up muting everyone. When using multiple screens it is laborious to find the control buttons, such as to start a session. Additionally, when a recording is done I have found it difficult to find them, there should be an easier way to retrieve them."
"Tenable Nessus could improve the reporting."
"The user interface of Tenable Nessus feels outdated and could be more user-friendly."
"Remediation needs improvement."
"We've faced situations where we required support on a Friday, and support wasn't available."
"We have the highest privilege in the application, and at least for members with the highest privilege, having the capability to reach out to the vendor directly from the application would be beneficial."
"It would be extremely helpful to have a community group around the product."
"The product helps, but the reporting relies heavily on Power BI. It is limited to graphical views and requires additional filtering, posing operational challenges."
"There are several areas needing improvement. The product helps, but the reporting relies heavily on Power BI. It is limited to graphical views and requires additional filtering, posing operational challenges."
"Their support is good, but there are some flaws as well. We often encounter some issues that are not applicable to Vulcan Cyber as a whole; they apply only to us because we have customized requirements. In such cases, when we reach out with specific data and issues to their support team, they sometimes come back and say that the issues have been resolved. However, when we test to see if they have been remediated, they are still there."
"Mainly, what I would like from them is more maintenance of the different connectors they have in the platform."
"I would rate the tool between six and seven because there have been instances when the tool was down, and I couldn't access Cyber reports. Additionally, the Vulcan Cyber team made changes to the tool and did not notify us."
 

Pricing and Cost Advice

Information not available
"The price of Tenable Nessus could improve, it is expensive."
"The product pricing is dynamic and varies based on the specific needs of each project and customer."
"Nowadays, your vulnerability applications are going to be kind of pricey because lots of them, including Rapid7, are based upon a base price, but then they add in the nodes. That's where they get you. If you're a big network, obviously, you need to scan everything. Therefore, it's going to be costly. The risk and insurance money associated with having ransomware on my networks is going to cost me more money, time, and marketing than the price of the tool. That's why I'm speaking only as an information security officer to security operations. This is the tool that is there in my toolbox to say whether we vulnerable or not. At this point, I don't care about how much it costs my company to have it because if I wasn't able to report it and we got ransomware, then who cares? I'm probably going to be out of business because it happened. That's why I don't care about the price. I have it, and I could use it effectively and do my report. At the end of the day, even if we get ransomware, as long as I reported it, followed my protocol, and put in the change, irrespective of whether it was ignored or denied, I did my job."
"I rate the product's price seven or eight on a scale of one to ten, where one is low price and ten is high price."
"The price of the solution is reasonable."
"The solution has a single price for unlimited assets."
"Its price is high for Libya. The companies here in Libya don't have the awareness of and a good budget for cybersecurity services. If you want them to go for a product, you need to provide something different. This differentiation is related to the price. They should give about 40% to 45% discount per person on the current cost."
"Nessus is affordable, but its licensing model could be improved with more flexibility for adding assets."
"Our leadership knows better about the pricing. As per my knowledge, which might not be accurate, its price can come down."
"Its pricing is quite fair compared to what is out there in the market, especially compared to the tool from Microsoft. It is a SaaS platform that has an annual cost, so it is something that is already used by many companies. It is quite affordable."
