Member And Investor at OpenWeb
Seemplicity sort of multiplies maybe 4x what we would have to spend in terms of employee hiring or actual analysts to be able to triage and remediate these vulnerabilities.
Managing Director
I was also able to pay for the tool twice over by using it for tool rationalization.
Vice President Of Security Architecture And Engineering at a hospitality company with 10,001+ employees
With security, it is always hard to quantify, and we did not really save money, but we used time more effectively and changed our way of working.
Cyber Security Architect at a retailer with 10,001+ employees
We have seen an absolutely clear return on investment in Nucleus Security, and it primarily shows up in massive time savings and vastly improved resource utilization.

Room For Improvement

Seemplicity users request improved integrations, enhanced reporting, and advanced AI capabilities alongside better UI, governance, and end-to-end mapping.
Nucleus Security requires intuitive UI, enhanced reporting, streamlined integration, and better onboarding with customizable dashboards and exposure management.
Pentera requires UI enhancements, better cloud and virtualization capabilities, licensing flexibility, and affordability to attract more non-specialist users.
It would be nice if customers could perform the aggregation themselves on the spot to reduce that bottleneck.
Senior Security Engineer at Omnissa
There is room for improvement in a generic approach to queue management and more proactive collaboration with security analysts, developers, and infrastructure teams on tickets.
Member And Investor at OpenWeb
With the introduction of AI and agentic AI and more involvement in day-to-day tasks, it would be great if this platform starts remediating the vulnerabilities as well.
Senior Manager For Info Sec at X-Press Feeders
Nucleus Security needs a better view into exposure management, as exposure management and attack path management are missing.
Cyber Security Architect at a retailer with 10,001+ employees
Having more intuitive step-by-step visualized wizards or guided templates for building complex triage workflows would make the onboarding process much smoother for new team members.

Setup Cost

Seemplicity is praised by enterprises for its flexible, transparent pricing, cost-effectiveness, and straightforward setup, enhancing efficiency.
Enterprise users appreciate Nucleus Security's competitive pricing, straightforward licensing, and value-driven features despite initial costs.
Pentera's pricing divides users; some see it as valuable, others find the $120,000 fee substantial yet noteworthy.
Pricing and licensing were straightforward, and we had direct discussions with the CEO of the company, which allowed us to arrive at a price point that worked for both sides.
Member And Investor at OpenWeb
Licensing was clear and predictable; I appreciate there being no surprise costs creeping in after the fact, especially as someone who has to plan budgets.
Senior Manager For Info Sec at X-Press Feeders
They did not come to us with a take-it-or-leave-it price; they sat down with us.

Senior Manager For Info Sec at X-Press Feeders
It helps us accelerate the amount of time it takes to remediate and patch those systems and ensure that those systems are essentially secure and not vulnerable to exposure.
Managing Director
By centralizing everything, Nucleus Security has completely eliminated that friction and dramatically cut down on alert fatigue across our infrastructure and support teams because the platform prioritizes risk based on real-world threat intelligence.
Manager at a computer software company with 201-500 employees
The risk-based prioritization has helped my team focus on the most critical vulnerabilities by considering severity, asset context, and the remediation priorities.
Head of Security at a consultancy with 51-200 employees

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.

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.

Automated testing has reduced manual effort and improves remediation of critical vulnerabilities
The biggest friction point with Pentera is the need for more granular control or the ability to exclude specific sensitive systems, as well as the necessity for the cloud environment to mature. While Pentera excels in on-premises and hybrid setups, its AWS and Azure attack path simulation is not as deep compared to others.If I could change one thing in Pentera to improve my workflow the most, it would be the platform UI because some security team members are not penetration testing specialists, making it difficult for them to navigate. I would make it easier with more guided workflows.
