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.
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."
"Overall, we have seen about eighty-seven percent reduction of the number of vulnerabilities that require urgency to remediate, specifically the number of criticals."
"We saw benefits from Zafran Security almost immediately after deploying it."
"We are able to see the real risk of a vulnerability on our environment with our security tools."
"The features that I have found most valuable with Skybox Security Suite, and this is because I work on the security side, are the firewall assurance, the change manager and the vulnerability control. These three features are the most impressive from Skybox Security."
"When you import all the assets that you have, like desktops, servers, networks, devices, routers, and then firewalls, and other products, then Skybox makes like, a model of the network, but with context. So, it is not just a model in VIZIO. Or something like it like that. You get the model with context, and, like, it looks like a real network in a real-time. So you can check your network and the security of your network on that model."
"instead of asking for firewall rules which may or may not be relevant, or could already be there, or could be over-permissioned, Skybox can be used to map out the resources that that application is going to use and provide the exact rules that an application would require to function correctly. If the traffic isn't able to flow for the application, if it's erring out, Skybox can be used to troubleshoot that and say, "All right, where is the traffic being stopped and why, and how do I fix that.""
"Skybox Security Suite is cost-effective."
"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."
"Security review is the most important feature, because it offers a single pane of glass to analyze multiple firewalls."
"The most valuable features of Skybox Security Suite are all the modules that are provided, such as vulnerability assessments and network, and firewall assessments."
"The solution offers very nice dashboards and they've recently added a very good Java-based web interface."
"The most valuable feature of this solution is the vulnerability assessment."
"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."
"The scans are the most valuable aspect of this solution."
"Tenable SC is good for reporting and alerting. The filtering feature is also very valuable. Its integration with multiple vendors is quite good. It can be integrated with SIEM solutions and PAM solutions such as Thycotic, which is very helpful."
"Has a great advanced scanning feature."
"The initial setup process is simple."
"Tenable is the leading product for vulnerability scanning."
"The predictive prioritization features are pretty good. They do a lot of research and we trust the research that they do internally. They have knowledge of what's going on with many companies, where we only get a view into what's going on here. So the ability to get best practices out of them as part of this solution, is valuable to us."
 

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 initial setup with Skybox Security is hard. You need one or two strong security engineers on your team."
"It's expensive."
"Change Manager can be improved. If they can improve Change Manager so that whatever we want to do on a firewall, we are able to do it through Change Manager, it will be helpful for us. Whenever we are doing a change, it only does them at an L3 and L4 level, but all the firewalls are at the application layer. So, whatever needs to be done on the firewall, we aren't able to get it done through Change Manager. Currently, this functionality is not there because of which we are sometimes losing customers. I can create a role on Layer 3, Layer 4, but when it comes to the application layer, such as configuring and defining URLs or other things at the application level, it can't be done through Change Manager. Customers demand that they should be able to do everything through Change Manager. They don't want to do it through some other mechanism to accomplish their complete change management policy. They don't want to use a firewall manager because sometimes, they don't have any manager. They ask if they can use our solution so that a manager is not required. If Change Manager can do all the management automatically without involving any other manager, it will be great. They can also provide better integration with other managers so that everything can be done through a central point."
"The cloud site could be better. They should provide some use cases to help users."
"The vendor's support is terrible."
"Skybox should improve their UX features by making them easier to use."
"Reporting. A lot of the reports, out of the box, are limited to a certain number of either configuration violations or access rule violations. So when you first set up a new firewall to be monitored by Skybox, you don't get a real full report. You have to really tweak it to get everything."
"The primary room for improvement would be to enable a web interface, which is not something which is there in the product. This is supposed to have come a year, a year and a half ago, but still has failed to come out. It still needs a client application to be installed on a workstation to be able to access that server and then run these reports. So I cannot extend that access to anybody. It has to be one administrator all the time. So unlike a web interface, where you can give multiple users simultaneous access and generate the various reports, that isn't a possibility at the moment."
"In terms of configuration, there is some level of flexibility that we are not able to achieve."
"It's important for Tenable to catch up on testing capabilities that are present in solutions like Qualys."
"Though the solution's technical support is responsive, they do take a lot of time, making it one of the solution's shortcomings that needs improvement."
"The reporting side can be improved. The dashboards are nice, but exporting things out for reports for management was a little tough."
"It could be more user-friendly for creating custom reports."
"For downloading reports, we have to go to the scan and then we have to go to the reports and download the Excel or CSV or PDF. I think these menus and clicks can be minimized."
"Support could be faster."
"Tenable's reporting engine needs improvement. It needs to be more efficient and add more features."
 

Pricing and Cost Advice

Information not available
"I rate the pricing two on a scale of one to ten, where one is very expensive, and ten is cost-effective."
"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."
"Fully understand the total cost of ownership. They have gone to a new model where you have to replace the hardware every X amount of years at a very substantial cost and fully understand your intended number of nodes. To operate a firewall, you have to pay two licenses, a firewall node and a network node. If you are a reasonable-sized organization, this gets expensive very quickly."
"Skybox comes with extra licenses and has a change management license. The licenses are expensive, but they come with extra value."
"Currently, the licensing costs me about $300 USD for the year. This is a huge amount for my environment."
"The solution is based on a subscription model for annual licenses."
"The price of the Skybox Security Suite can be expensive."
"The product's pricing is excellent value. In terms of licensing, make sure you understand your network components, all your hops through your network, thoroughly, before you decide on the total cost. If you want to do point-to-point flow analysis and such, you need to have the configuration of all the devices in between point A and point B. A lot of people don't realize all their network components until they start using this product."
"I would rate the pricing a nine out of ten, where ten is expensive. It is the most expensive tool my company is using."
"We're able to save because we don't have to employ more staff members to help wit ht he scheduling of the scans, running the reports or sending them out to the systems owners. That alone is a big ROI for us."
"We pay around 60,000 on a yearly basis."
"I use a local license to perform penetration testing and I'm pretty happy with everything when it comes to pricing and licensing."
"The licensing costs for this solution are approximately $100,000 US, and I think that covers everything."
"The pricing depends upon the number of IPs."
"Tenable is open-source."
"We're a Fortune 500 company... our licensing costs [are] in the seven figures."
