Centralized security testing has improved vulnerability remediation and compliance reporting
I recommend more enhancements focusing on penetration testing for both SSL over HTTP and non-SSL over HTTP, specifically targeting the RCP Rich Client Platform and Equinox frameworks that allow on-premises desktop applications to be tested simultaneously. I believe those would significantly improve the tool in the future. I choose eight as my rating primarily because of the installer app; it becomes challenging to identify the actual vulnerabilities. Once we build this installer—rather than just working on the codebase—sometimes, we face gaps considering the build parameters and conversions to the installer. Identifying those gaps is an area that could use improvement after the installer or desktop application testing, which would be beneficial. That is the only reason; otherwise, I could easily rate it a ten out of ten given its smooth operational process.

Streamlines prioritization but reporting needs enhancement
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. The inability to download specific asset details directly from the Power BI portal is a drawback, particularly for non-technical users, though it provides high-level executive summaries. The reporting model should be enhanced so that we have the flexibility to download. We have requested a few features, and they are open to accepting those requests. It needs ITSM improvements. It has out-of-the-box integration with ServiceNow, but the customer is using BMC Helix ITSM. We would like an integration with BMC Helix ITSM. When uploading CSV files without an out-of-the-box connector, duplicate entries for assets occur. We have already reported this to them, but we are not sure when they will fix it. It will significantly benefit if we can directly upload business context information from CMDB without manual merging efforts. It can also have automatic remediation capabilities through SCCM or something else.

Quotes from Members

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

Pros

"We have seen clear compliance and risk control outcomes more than other operational metrics, including fewer process gaps during documentation and safety checks, strong consistency in following protocols for handling, traceability, and staff awareness, better audit readiness, a lower chance of procedure errors, and faster escalation when something appears out of standard, which is very important for us in the healthcare sector."
"I think the best features that Nucleus Security offers are purely the faster remediation to dev tools, which is crucial for managing, prioritizing, and fixing vulnerabilities while helping operational pipelines run these vulnerability management tools."
"The most notable aspects include having prioritization capabilities and custom scripts."
"Vulcan Cyber offers a single pane of glass for centralizing our security data."
"Vulcan Cyber is a very good tool."
"The automation capabilities using the Vulcan API platform or the API feature allow me to easily automate scripts and reports and schedule them."
"They recently upgraded their UI, which is great. It is user-friendly."
"One of the features that I find valuable is the ability to bifurcate the report according to the many options available."
"Out of the three solutions I've used, Vulcan Cyber is the superior option."
"The interface of Vulcan Cyber is intuitive with a lot of information about vulnerabilities, which helps in classifying and analyzing threats."
 

Cons

"Protocols can be too complex in practice sometimes, and some processes can feel heavy and disconnected from our daily workflow."
"I choose eight as my rating primarily because of the installer app; it becomes challenging to identify the actual vulnerabilities."
"It was a rough year in terms of setup. I had to set it up and onboard it. It was a significant effort from my side at least."
"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."
"Mainly, what I would like from them is more maintenance of the different connectors they have in the platform."
"We've faced situations where we required support on a Friday, and support wasn't available."
"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."
"We wish we had more insights into how they weigh the risks associated with the threat intel."
"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."
"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
"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."
"Our leadership knows better about the pricing. As per my knowledge, which might not be accurate, its price can come down."
