JL
Vice President Of Security Architecture And Engineering at a hospitality company with 10,001+ employees
Unified vulnerability data has reduced risk and currently cuts duplicate tools and license costs
Seemplicity can be improved by adding additional graphs and charts that make it easier to do trending over time. I had to do some of that manually via manual reports, but Seemplicity already has a feature request for this. Seemplicity has done a pretty good job of keeping up with integrations. One gap that I identified and that Seemplicity is trying to fill now is having a complete end-to-end mapping. Seemplicity currently looks at the external attack surface using tools like Censys, and then looks at the internal side, examining what is in AWS and other clouds using CSPM. However, there is not anything that currently ties a property on the outside to a system on the inside, especially when you have additional security layers like web application firewalls that actually mitigate the risk.

Experience seamless integration and effective dashboard while considering improved EDR configuration support
The way Cymulate works for EDR could be improved, as it drops payload and requires action from the EDR console for remediation, which can block the whole process of Cymulate execution. They should create some KB articles for the granular exclusion from different platforms and improve their technical assistance support.

Vulnerability And Compliance Manager at a insurance company with 5,001-10,000 employees
Unified vulnerability view has improved risk-based decisions but reporting still needs work
One of the main issues with Nucleus Security is its lack of reporting capability. The user interface resembles an early 2000s application style, and although its speed is decent, it could be improved as more data is ingested. The overall appearance and feel need work, especially compared to modern applications from Rapid7, Qualys, and Tenable, which have more engaging user interfaces. The reporting capability is severely lacking; not being able to filter to granularity or have custom built queries is an annoyance that needs an overhaul. Additionally, there are bugs that have not been resolved, such as when you create a report and remove an asset, the asset still appears in the report despite not being present in the system anymore, leading to issues that need to be addressed quickly. Nucleus Security can become a difficult investment because I already have a vulnerability management solution, and I question where Nucleus Security fits with its licensing model. While I acknowledge automation has been described, it would be amazing to control the entire vulnerability management workflow from Nucleus Security without needing to log onto other systems. Having controls or actions that can be sent from the console down to the scanner for rescans would be beneficial. If Nucleus Security is going down this path, it should ensure that it becomes a one-stop shop for vulnerability management across multiple applications.

Quotes from Members

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

Pros

"When we started with Seemplicity, we saw an 85% reduction in the number of tickets through deduplication, and that is significant for our teams who are swamped with issues."
"The biggest impact Seemplicity has had on my organization is turning what used to be a fragmented, manual process into something structured and accountable."
"Seemplicity has helped us see a return on investment by reducing the need for an L1 analyst for AppSec findings through its categorization, deduplication, and automatic remediation assignments, which has significantly decreased the headcount required for initial analysis."
"Before we really struggled with meeting SLAs that were in place because we did not have the information we needed and there was too much back and forth, now we nearly have a perfect SLA meeting time."
"I was also able to pay for the tool twice over by using it for tool rationalization."
"Seemplicity is helping us generate immense ROI in terms of helping secure our infrastructure, applications, endpoints, and understanding vulnerabilities that we really did not have a good process of understanding before."
"Seemplicity is doing amazing work, and organizations were able to better meet their SLAs, better communicate to their leadership and executive level about the overall risk and exposure levels, and overall have a better understanding of what they are dealing with."
"Seemplicity has positively impacted my organization by helping reduce the overhead for our SecOps team to manually create vulnerability tickets."
"Cymulate is easy to set up, install, and configure."
"The reporting capabilities are very good."
"The most valuable feature for us is the zero-day."
"Cymulate has positively impacted our organization by helping us to take care of the efficacy and reviewing the policies and configuration."
"With Cymulate, the best features are the capacity to test the EDR or malware, anti-malware solution."
"The security validation feature helps my organization in assessing our security posture."
"Nucleus Security has impacted my organization positively by providing a single pane view of vulnerabilities from different connectors and enabling the automation of reporting and alerting on findings that are out of due date or out of SLA."
"The best features that Nucleus Security offers in my experience are the unified integrations with all of the different vulnerability management platforms."
"Nucleus Security has fundamentally changed how we manage our vulnerability lifecycle and made our entire incident response process much more proactive, organized, and reliable."
"The best features Nucleus Security offers, in my opinion, are that it is really great in showcasing things and providing centralized vulnerability management."
 

Cons

"The capability out of the box today is decent, but over time, if we can allow users and organizations to build their own view and how they want to report on things, that would be a great value add."
"For Seemplicity, I would say two things for improvement. First, reporting customization could go further because this industry is evolving; the CEO tries to get much information that they are looking for."
"Seemplicity could use more improvement around the user interface."
"Seemplicity could be improved with some of the aggregation accessibility. Currently, it is a bit of a black box and can be a bit of a bottleneck."
"Seemplicity can be improved by adding additional graphs and charts that make it easier to do trending over time."
"Every tool, including Seemplicity, can improve, and I think it needs to further enhance its deduplication capabilities and understand how to integrate with more security tools, especially as new AI security tools emerge."
"As the account is growing, some of the dashboards are slowing down, so optimizing that could be one area for improvement."
"We have had some trouble with the agents."
"The way Cymulate works for EDR could be improved, as it drops payload and requires action from the EDR console for remediation, which can block the whole process of Cymulate execution."
"I will be honest, we have it, but in the last year, I didn't maintain the system until a month ago."
"The product must provide consultancy for initial setup."
"The reporting process requires significant improvement as it often takes longer than expected and the quality is lacking."
"The cost can be quite high, and it impacts scalability as more simulations require additional expenses."
"Nucleus Security needs a better view into exposure management, as exposure management and attack path management are missing."
"While the platform is incredibly powerful, the initial configuration curve of Nucleus Security can be a bit steep."
"One of the main issues with Nucleus Security is its lack of reporting capability."
"On a scale of one to ten, I would rate Nucleus Security overall a six."
