Tenable Vulnerability Management and Nucleus Security are both in the vulnerability management and security category. Tenable appears to have a slight advantage due to its feature set although Nucleus offers significant advantages in flexibility and centralized management.
Features: Tenable Vulnerability Management offers advanced threat detection, broad asset coverage, and adaptive user support. It is notable for its continuous network scanning and automated risk assessment. Nucleus Security is focused on flexible integrations, providing compatibility with many security tools and a centralized platform that enhances vulnerability insights. While both products add value, Tenable’s tools address more diverse needs.
Ease of Deployment and Customer Service: Nucleus Security offers a straightforward deployment model with strong customer service and agile integration options that streamline onboarding. Tenable Vulnerability Management, though a bit more complex in deployment, provides comprehensive customer support that handles its broader toolset.
Pricing and ROI: Tenable Vulnerability Management has a competitive pricing structure supporting its capabilities and offers good ROI for complex IT environments. Nucleus Security, while more affordable, provides value with its integration options and high ROI for organizations focusing on centralized management. Both have compelling setups, though Tenable's pricing is tightly aligned with its features.
It has saved about 90% of our time.
TotalCloud has generated overall savings of 30 to 40 percent across various departments.
CallStream helps us integrate and automate tasks.
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.
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.
Automation handles reporting on a scheduled basis and alerts system owners about their posture each week.
They are helpful, respond to my queries, and can answer any question.
Qualys's tech support is highly responsive, providing multiple ways to interact with them.
Qualys' customer service provides quality answers, but the response time is long, even though it is within the SLA.
I would describe Nucleus Security's customer support as absolutely fantastic.
Customer support is great; I have always had communication with executive leaders, been able to have roadmap calls, and talk with support.
It needs improvement in response time and addressing feature requests promptly.
The technical support of Tenable Vulnerability Management is available 24/7, and whenever we require support, we can get it within five minutes.
We had used Tenable's expert support services in order to make sure that we run Tenable Vulnerability Management on a continuous basis and are able to utilize their services.
We started our organization about nine months back. We started with about 30 users, and we now have more than 100 users.
Our organization currently uses it to manage over 1200 web applications.
It is absolutely scalable, and I would rate its scalability as nine out of ten.
The platform has done a great job of handling both stability and scalability excellently.
The scalability of Nucleus Security is fairly impressive; even when ingesting multiple assets, there is no noticeable impact.
They can seamlessly scale the number of endpoints from 100 to 1,000,000 in a day.
Tenable Vulnerability Management is highly scalable.
With the growing needs of our company, Tenable Vulnerability Management is able to safely adapt.
Overall, the support provided has been excellent.
It is a stable solution, which is why we chose it.
Continuous monitoring is crucial to ensure system stability and avoid vulnerabilities or threats.
We rarely, if ever, encounter downtime or performance degradation, even when the platform is running massive automation rules and background synchronization tasks during peak operational hours.
I have faced no stability issues with Tenable.
The stability is commendable, and I would rate Tenable ten out of ten.
The stability of Tenable Vulnerability Management is highly reliable.
Ideally, the scanner should automatically detect and scan all subdomains, even if not explicitly defined, ensuring comprehensive vulnerability assessment.
Ideally, updates should be more immediate, enabling quicker implementation of solutions.
Our goal is to integrate all these functions into Qualys, creating a single dashboard for comprehensive security monitoring and management.
Nucleus Security needs a better view into exposure management, as exposure management and attack path management are missing.
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.
It could be integrated with SentinelOne, but it was not showing any SentinelOne alerts.
They should also accelerate the process of implementing new features upon request.
I would suggest HP WebInspect as a better option than Tenable.io.
Tenable Vulnerability Management is not very effective for real-time risk prioritization for our organization's security strategy.
Qualys TotalCloud's pricing is currently acceptable, it is becoming increasingly expensive.
Pricing is managed by our finance team; however, Qualys TotalCloud offers cost-effective licensing flexibility.
Qualys TotalCloud is expensive, but it offers a premier solution with no headaches.
The licensing model is straightforward, with one license across multiple assets for multiple connectors.
Tenable charges around $40 per device, while Rapid7 costs $10 to $15 per device.
I would not say very expensive for Tenable Vulnerability Management; it is not prohibitive, but at the same time, there are some other tools in the marketplace which are offering the same kind of services that Tenable offers, the same kind of features that Tenable has offered at a lesser cost.
This view of risk helps reduce the work we would have to do to combine multiple sources to prioritize risk.
It will help cybersecurity professionals monitor the cloud and find vulnerabilities.
We are enjoying the new feature, FlexScan, which is valuable for Internet-facing VMs.
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.
The risk-based prioritization has helped my team focus on the most critical vulnerabilities by considering severity, asset context, and the remediation priorities.
The best features that Nucleus Security offers in my experience are the unified integrations with all of the different vulnerability management platforms.
Tenable enables vulnerability management through potential AI integration that consolidates efforts and resolves multiple vulnerabilities simultaneously.
The main benefit of integration with Tenable Vulnerability Management is that there will be no lack of missing vulnerabilities when it comes to the patching environment.
The main benefits that Tenable Vulnerability Management provides for me as an end user include saving time and money and streamlining processes.
