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.

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.

Exposure monitoring has provided clear risk insights but still needs stronger cloud and data posture
I believe there are two to three areas where Rapid7 Exposure Command can be improved. First, cloud integrations and the ability to assess cloud posture are essential components of an organization's external attack surface nowadays. Rapid7 Exposure Command has the cloud posture assessment feature, but in my opinion, it should be linked with cloud compliance requirements being introduced locally and internationally. Secondly, regarding data criticality, Rapid7 Exposure Command integrates the DSPM feature, which stands for Data Security Posture Management. I believe this feature is present, but it requires enhancement with global data protection regulations such as GDPR. I am learning about more features in products such as Rapid7 Exposure Command. I mentioned cloud posture assessment across Oracle Cloud, Azure Cloud, and AWS Cloud. Features specific to these cloud offerings would be beneficial. With AWS having separate cloud offerings, Rapid7 Exposure Command must cover all available AWS offerings and relevant services. To be honest, this is an area where I am still learning, so I cannot provide a precisely detailed answer.

Quotes from Members

Pros

"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."
"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."
"I think of Seemplicity as a fantastic company and a fantastic partner to work with."
"I was also able to pay for the tool twice over by using it for tool rationalization."
"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."
"The biggest impact Seemplicity has had on my organization is turning what used to be a fragmented, manual process into something structured and accountable."
"We have seen improvements in remediation rates, as initially a lot of our metrics were in the red, but now all are in the green or yellow."
"Seemplicity has positively impacted my organization by helping reduce the overhead for our SecOps team to manually create vulnerability tickets."
"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."
"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."
"Compared to Tenable or Qualys, Rapid7 Exposure Command is definitely affordable for small-sized or mid-sized engagements, although there are some challenges with detection."
"Rapid7 Exposure Command provides me with satisfaction knowing that my external attack surface and digital risk are being monitored."
 

Cons

"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."
"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 could use more improvement around the user interface."
"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."
"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."
"As the account is growing, some of the dashboards are slowing down, so optimizing that could be one area for improvement."
"On a scale of one to ten, I would rate Nucleus Security overall a six."
"One of the main issues with Nucleus Security is its lack of reporting capability."
"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."
"Rapid7 Exposure Command is not as easy to deploy compared to Qualys, and the detection rates are lower than Qualys."
"In the Pakistani market, Rapid7 Exposure Command's pricing is on the expensive side, and that represents one of the challenges we are facing."
