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.

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.

Has improved our vulnerability tracking and supports cloud-based monitoring with scheduled scans

We don't have any issues with Tenable One Exposure Management Platform. It works well for us, but the only problem is the licensing aspect. In the license, it becomes problematic because when we go to cloud security for vulnerability management, it will take five licenses instead of the one-on-one license that vulnerability exposure management requires. The license needs to be reviewed.

Quotes from Members

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

Pros

"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."

"Seemplicity has positively impacted my organization by helping reduce the overhead for our SecOps team to manually create vulnerability tickets."

"I think of Seemplicity as a fantastic company and a fantastic partner to work with."

"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."

"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."

"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."

"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."

"I was also able to pay for the tool twice over by using it for tool rationalization."

More Seemplicity pros

"The best features that Nucleus Security offers in my experience are the unified integrations with all of the different vulnerability management platforms."

"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 fundamentally changed how we manage our vulnerability lifecycle and made our entire incident response process much more proactive, organized, and reliable."

"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."

"I think it's a good product for risk-based or exposure-based vulnerability management."

"We find Tenable One Exposure Management Platform vulnerability prioritization effective overall because, with the scheduled scan running on our set schedule, we can remediate any findings and check on the next schedule if issues are closed, making it much easier for us to monitor vulnerabilities."

"The product gives us a lot of insight."

"The feature of vulnerability management and discovery is what I use."

"Tenable EP is a great overall product for our customers; it's great at helping customers to identify current risks, it helps customers manage their risk, users can effectively analyze risk and can assign team members to take a look at items as well, the solution is very easy to set up, technical support is very helpful and responsive, and the pricing is pretty good."

"The solution is very easy to set up."

"For me, the setup has been an easy process."

Cons

"As the account is growing, some of the dashboards are slowing down, so optimizing that could be one area for improvement."

"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 can be improved by adding additional graphs and charts that make it easier to do trending over time."

"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."

"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."

"Seemplicity could use more improvement around the user interface."

"While the platform is incredibly powerful, the initial configuration curve of Nucleus Security can be a bit steep."

"On a scale of one to ten, I would rate Nucleus Security overall a six."

"Nucleus Security needs a better view into exposure management, as exposure management and attack path management are missing."

"One of the main issues with Nucleus Security is its lack of reporting capability."

"The license needs to be reviewed."

"It would be nice if the product provided an agent for enforcing policies."

"The sensor update is a challenge that Tenable needs to address. Sometimes they behave abruptly, requiring me to rework reinstalling the sensors on the endpoints."

"The product has limited reporting capabilities and it isn't great at allowing for customization in reports."

"Tenable needs to provide a better way to manage private clouds."
