Executive SummaryUpdated on Dec 14, 2025

Tenable Security Center and Skybox Security Suite compete in the vulnerability management and security solutions category. Tenable appears to have the upper hand due to its intuitive asset discovery and dynamic dashboards, while Skybox excels in network modeling and change management.

Features: Tenable Security Center provides comprehensive vulnerability assessments, dynamic dashboards, and effective asset discovery, making it a versatile choice for organizations with diverse compliance needs. Skybox Security Suite offers robust firewall and vulnerability management, extensive network path analysis, and strong compliance reporting, making it suitable for complex enterprise environments.

Room for Improvement: Tenable could improve dashboard flexibility, simplify initial configurations, and enhance export functions for vulnerability metrics. Skybox's interface needs to be more user-friendly, with suggestions for better reporting flexibility and automation features. Expanding firewall rules provisioning compatibility and improving customer support are additional areas identified for Skybox.

Ease of Deployment and Customer Service: Tenable Security Center is mainly deployed on-premises, with some hybrid cloud support, and receives praise for its prompt and knowledgeable customer service, though response times can vary. Skybox supports both on-premises and hybrid cloud environments, offering deployment flexibility. Its customer support is generally quick but can vary in detail and efficiency between local and international teams.

Pricing and ROI: Tenable is mid-range priced and perceived as costly compared to alternatives like Qualys and Rapid7, but offers significant ROI in breach prevention, with asset-based licensing potentially high for large enterprises. Skybox’s pricing, while seen as expensive, is competitive in offering detailed network and vulnerability solutions, providing a good cost-to-value ratio for complex scenarios. Its modular pricing adapts well to diverse enterprise needs.

Has become an indispensable tool in our cybersecurity arsenal

While Zafran Security is already a powerful tool, there are areas where it could be further improved to provide even greater value. One key area for enhancement is the searching capabilities within its vulnerabilities module. By incorporating the ability to create Boolean searches, users would gain the ability to apply more complex filters and customize their search criteria. This would greatly enhance the precision and efficiency with which security teams can identify and prioritize vulnerabilities. Having such tailored search capabilities would save time and resources by narrowing down vast lists of vulnerabilities to those that meet specific parameters relevant to our unique risk environment. Additionally, integrating more robust reporting and visualization tools would be advantageous. Enhanced dashboards that offer customizable visual representations of risk configurations and threat landscapes would facilitate better communication with stakeholders, making it easier to explain vulnerabilities and the rationale behind certain security measures. This would also aid in demonstrating the improvements and value derived from existing security investments to leadership and non-technical team members.

Tool identifies vulnerabilities and monitors connectivity effectively

Skybox Security Suite was a very good tool for my organization. I used it for monitoring connectivity between internal and external sites, monitoring our AWS instances, and ensuring workstations and Layer 3 devices met security specifications. The tool successfully helped in preventing vulnerabilities and breaches, but unfortunately, operations ceased before completing a migration to SaaS.

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."

"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 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."

"With Zafran Security, it integrates with your security controls, allowing you to take that risk score and reduce it based on the controls in place or increase the risk based on different factors, such as if the issue is internet reachable or if there's an exploit in the wild."

"Zafran is an excellent tool."

"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 most impressive feature is optimization and clean-up."

"The most valuable feature is the compliance, whether it's access compliance or the configuration compliance, to make sure that all of our devices are configured as they're supposed to be, to limit access as much possible, to follow least-access guidelines."

"We are currently working on rule review and compliance. The logging features are good."

"This type of tool does a great job of reaching into those other devices producing risk recommendations, compliance recommendations, and a single plane of glass to do your queries, so you can find where these rules might exist."

"Robust modules can be used for different parts of network security."

"Skybox allows organizations to reprioritize the vulnerability they attempt to patch and mitigate, based on the contextual awareness of the network."

"It shows me a client's or an organization's entire network. I can see everything."

More Skybox Security Suite pros

"The most important features are the dashboard and reporting. The dashboard provides statistics with graphs and bar charts for our management."

"I found the dashboard features very useful. It made it easy to track remediation progress. I could publish dashboards to remediation teams and track the progress on the dashboards."

"We really love the Security Center dashboard. It basically performs vulnerability scanning and then outputs a vulnerability data."

"Tenable.sc's best features are the availability model, accident management, and scoring."

"Has a great advanced scanning feature."

"Overall, I rate the solution 9.8 out of 10."

"The most valuable features of Tenable SC are scanning, reporting, dashboards, and automation."

"The valauble feature is compliance reporting system."

More Tenable Security Center pros

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 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."

"The most recent update was not tested with all of the vendors before it was released, so some of the features are misbehaving."

"The stability is something that is questionable. I don't know whether it is because of the kind of infrastructure we have or because of the product in itself. We're running it on a virtual machine right now. Maybe once a month, or once in every 45 days, it requires a restart because the application fails to connect. So I have to restart the whole Skybox Manager itself, the Skybox server itself, and then connect to it from our Skybox Manager."

"The tool does not offer options for customization."

"There is room for improvement in the technical support."

"They are not satisfied with the complexity of the solution and the price."

"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."

"There is room for improvement in pricing. It would be better, especially if a customer bought all four modules."

"Skybox Security Suite's attack surface management feature needs improvement."

More Skybox Security Suite cons

"Its reporting can be improved. It is not easy to generate a scan report the way we want. The data is okay, but we can't easily change the template to make it look the way we want."

"The user interface can be improved."

"Tenable has some problems with agents going offline during scanning and lag between agents and the security center."

"Tenable.sc's user interface could be improved."

"In terms of configuration, there is some level of flexibility that we are not able to achieve."

"Tenable's technical support has declined in quality over time. While they used to be excellent, achieving ratings of eight or nine, they now rate around six or seven due to longer response times and less thorough assistance."

"The GUI could be improved to have all concerns and priorities use the same GUI, allowing them to see all tickets, assign vulnerabilities, and assign variation failures to each member of their team."

"Tenable SC can improve by adding more integrations with HCI-type tools and more accurate vulnerability detection."

More Tenable Security Center cons

Pricing and Cost Advice

Information not available

"Skybox comes with extra licenses and has a change management license. The licenses are expensive, but they come with extra value."

"I think for the cost, what we got definitely is worth it. The only caution I would give is that whenever you license for Firewall Assurance at the same time, for some weird reason, you have to get one Network Assurance license, just to manage one firewall. That's a little bit of overkill. But otherwise, in general, the pricing is fairly okay."

"Skybox Security Suite has indeed helped us reduce costs. The prices of AlgoSec and Skybox Security Suite are approximately 50 percent different. The tool may require special vendor support from abroad, resulting in slightly higher costs. Its pricing is in the middle."

"When compared with other companies, the license is more costly."

"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."

"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 software is expensive. I rate its pricing an eight out of ten."

"It's expensive."

More Skybox Security Suite pricing and cost advice

"The tool provides competitive pricing."

"The pricing is more than Nexpose."

"We're happy with the licensing cost and find it affordable."

"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."

"It is a bit expensive. Everything is included in the license."

"It is slightly more expensive than other solutions in the same sphere."

"Tenable is open-source."

"We pay around 60,000 on a yearly basis."
