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.

Enable secure development workflows while identifying opportunities for faster scans and improved AI guidance

Checkmarx One is a very strong platform, but there are several areas where it can improve to support modern DevSecOps workflows even better. For example, better real-time developer guidance is needed. The IDE plugin should offer richer AI-powered auto-fixes similar to SNYK Code or GitHub Copilot Security, as current guidance is good but not deeply contextual for large-scale enterprise codebases. This matters because it reduces developer friction and accelerates shift-left adoption. More transparency control over the correlation engines is another need. The correlation engine is powerful but not fully transparent. Users want to understand why vulnerabilities were correlated or de-prioritized, which helps AppSec teams trust the prioritization logic. Faster SAST scan and more language coverage is needed since SAST scan can still be slow for very large mono-repos and there is limited deep support for new language frameworks like Rust and Go, along with advanced coverage for serverless-specific frameworks. This matters because large organizations want sub-minute scans in CI/CD as cloud-native ecosystems evolve fast. A strong API security module is another area for enhancement. API security scanning could be improved with active testing, API discovery, full Swagger, OpenAPI, drift detection, and schema-based fuzzing. This is important as API attacks are one of the biggest AppSec risks in 2025. Checkmarx One is strong, but I see a few areas for improvement including faster SAST scanning for large mono-repos, deeper language framework support, more transparent correlation logic, and stronger API security that includes discovery and runtime context. The IDE plugin could offer more AI-assisted fixes, and the SBOM lifecycle tracking can evolve further. Enhancing integration with SIEM and SOAR would also make enterprise adoption smoother, and these improvements would help developers and AppSec teams move faster with more accuracy.

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.

Quotes from Members

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

Pros

"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."

"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."

"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."

"Zafran has become an indispensable tool in our cybersecurity arsenal."

"Once you implement Checkmarx One, you can be sure that you're getting value from the solution almost immediately because Checkmarx One also handles false positives very effectively, saving you time and saving your developers time."

"The most valuable feature is that it actually identifies the different criteria you can set to meet whatever standards you're trying to get your system accredited for."

"The main benefit to using this solution is that we find vulnerabilities in our software before the development cycle is complete."

"Most valuable features include: ease of use, dashboard. interface and the ability to report."

"The most valuable feature of Checkmarx is the user interface, it is very easy to use. We do not need to configure anything, we only have to scan to see the results."

"The most valuable features of Checkmarx are the automation and information that it provides in the reports."

"The most valuable features of Checkmarx are the SCA module and the code-checking module. Additionally, the solutions are explanatory and helpful."

"The most valuable features of Checkmarx are the Best Fix Location and the Payments option because you can save a lot of time trying to mitigate the configuration. Using these tools can save you a lot of time."

More Checkmarx One pros

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

"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 the rule compliance and the OS vulnerability checks."

"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."

"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."

"The solution's most valuable and unique assets are the vulnerability management and change management solutions because they identify mistakes in the network before implementation which reduces risks."

"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."

More Skybox Security Suite 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."

"Meta data is always needed."

"Checkmarx could improve the solution reports and false positives. The false positives could be reduced. For example, we have alerts that are tagged as vulnerabilities but when you drill down they are not."

"The plugins for the development environment have room for improvements such as for Android Studio and X code."

"Checkmarx needs to be more scalable for large enterprise companies."

"I would like to see the tool’s pricing improved."

"There are some downtimes when Checkmarx One is being upgraded to the latest version or some improvement is there."

"I expect application security vendors to cover all aspects of application security, including SAST, DAST, and even mobile application security testing. And it would be much better if they provided an on-premises and cloud option for all these main application security features."

"Its user interface could be improved and made more friendly."

More Checkmarx One cons

"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 features that I appreciated the most in Skybox Security Suite were not comparable with Tufin, as Tufin was far ahead in terms of the technology and the user interface."

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

"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."

"The company made bad business decisions impacting many clients and their own staff. Reporting could have been improved, and feature requests often were not implemented."

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

"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 vendor's support is terrible."

Pricing and Cost Advice

Information not available

"The pricing was not very good. This is just a framework which shouldn’t cost so much."

"It's relatively expensive."

"The solution is costly."

"I would rate the solution’s pricing an eight out of ten. The tool’s pricing is higher than others and it is for the license alone."

"It is an expensive solution."

"Most of my customers opted for a perpetual license. They prefer to pay the highest amount up front for the perpetual license and then pay for additional support annually."

"We're using a commercial version of Checkmarx, and we paid for the solution for one year. The price is high and could be reduced."

"This solution is expensive. The customized package allows you to buy additional users at any time."

More Checkmarx One pricing and cost advice

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

"I think the price is fair."

"The price of the Skybox Security Suite can be expensive."

"The solution is based on a subscription model for annual licenses."

"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."

"The price is not expensive."

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

"I rate the pricing two on a scale of one to ten, where one is very expensive, and ten is cost-effective."
