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.
NenadMijatovic - PeerSpot reviewer
Efficient in vulnerability management, stable and easy to use
Vulnerability management is the most valuable feature because it lets you focus on the most critical vulnerabilities. That's the important thing. Here in Serbia, there are not so many companies that have too many firewalls inside one company. So, they usually don't buy this model for Firewall Assurance unless there is some compliance. So you can prove that your firewalls are compliant. So, that model is not so important here in Serbia. It's for bigger companies. So, they usually buy network assurance to build the model of the network and vulnerability management to focus on the most important vulnerabilities. Moreover, Skybox can collect data for many vendors. From the endpoint protection vendors to the network equipment vendors to other security vendors. So, it supports more than one hundred vendors to collect data from them.
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The user interface of Tenable Nessus feels outdated and could be more user-friendly.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.

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."
"We are able to see the real risk of a vulnerability on our environment with our security tools."
"Zafran has become an indispensable tool in our cybersecurity arsenal."
"The solution offers very nice dashboards and they've recently added a very good Java-based web interface."
"Overall, the tool has helped us reduce risks. If any step is missing, it's easier for my team or engineers to identify it. The tool provides accurate recommendations based on the data. Its integration is easy, and I have integrated it with Fortinet firewalls."
"It can be integrated with a vulnerability management solution. When a client comes, apart from pitching network and firewall change management, we are recommending having vulnerability management. So, rather than just having the audit of the firewall, they can integrate it with their vulnerability management solution, which could be Rapid7, Qualys, or any other solution. This provides them the most value out of the platform. That is the way we are approaching our customer base."
"Skybox allows organizations to reprioritize the vulnerability they attempt to patch and mitigate, based on the contextual awareness of the network."
"The most valuable features are Firewall Assurance and Vulnerability Control."
"Key features for us include the firewall change audit every week. Also, being able to track firewall ACL usage, so that we can produce semiannual reports on ACL usage and shadowed and redundant rules on the firewall."
"The performance could be good because we chose it at the time, but it is too complex for us to appreciate its performance because we lack the necessary skills."
"The ability to appropriately prioritize vulnerabilities inside the environment, and then to have visibility into the traffic and rule sets of an organization, are two of the top capabilities that I recommend. Skybox is the only one that does both of those in a single platform."
"The solution is very stable."
"Tenable integrates well with other solutions such as SIEM and batch management."
"The vulnerability scanner is the most valuable feature."
"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."
"The support has been really cooperative."
"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 solution is the most dynamic one I have seen thus far."
"You can then direct your team to create a report on the discovered vulnerabilities."
 

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 tool does not offer options for customization."
"The support could be improved."
"There is room for improvement in the technical support."
"The solution needs improvement in firewall configuration checks. I would also like to see more configuration checks for Forcepoint and for other non-supported firewalls."
"The dashboard's UI is not interesting; it is quite normal. It would be better if something more attractive or similar useful information found in AlgoSec was available."
"The solution was quite technical. It would be easier to manage if the solution was more specific about aspects of the solution and provided more advisory around how to use it effectively. It would help users a lot if they were more clear about everything."
"Skybox Security Suite can improve the change management module. It is the one part of the tool that is used with the firewall devices and you have a change management module that is used to record changes of all firewalls in the company. It's not compatible with all brands, this is where they can improve the solution."
"The solution needs to move improve its interface to a full web browser version that is more accessible and doesn't require installation for use."
"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."
"EQA's and dashboards should be addressed in the next release."
"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."
"The product could have unique features similar to one of its competitors."
"Tenable Nessus could improve the price."
"Scans aren't done properly and some devices aren't pinged."
"To be honest, I haven't used it much to tell you that these are the things that should be improved. But I believe the UI should be enhanced somewhat. For example, there are two ways to find a report, and people are frequently confused as to which is the correct method for locating a full report. Sometimes they go in the opposite direction, so this is an area that may be improved."
"The price and scalability of the solution could improve."
 

Pricing and Cost Advice

Information not available
"Pricing is on the higher side. In terms of licensing, you should buy the complete suite rather than buying only the Change Manager. I think Change Manager with Vulnerability Control is something that would be interesting to look at."
"The price of the Skybox Security Suite can be expensive."
"I rate the pricing two on a scale of one to ten, where one is very expensive, and ten is cost-effective."
"Skybox comes with extra licenses and has a change management license. The licenses are expensive, but they come with extra value."
"Licensing is normally on a yearly basis. There may also be a perpetual license. Normally, the customers ask for a lower price. If you want to sell more, you have to think about it."
"When compared with other companies, the license is more costly."
"I would rate the tool's pricing an eight out of ten."
"Currently, the licensing costs me about $300 USD for the year. This is a huge amount for my environment."
"I would like to see better discounts."
"We paid about six thousand dollars per license."
"The price is reasonable."
"The price is okay. I would give it a seven out of ten, where one is cheap and ten is expensive."
"Nessus Manager is not an expensive product. It has its limitations, but the pricing reflects that. We have a yearly subscription."
"Tenable Nessus is affordable."
"Its pricing is great and can't be improved. It is very cheap. It is less than 2,000 pounds a license, and you can't really ask for more. It has unlimited IPs and unlimited scans. There are no particular pricing constraints. The only additional cost is the inherent cost of the people to actually review the actual scans."
"There is an annual license required to use this solution."
