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.
Whether managing 50 servers today or 500 tomorrow, performance or capacity are not hindered.
Tenable Nessus is definitely scalable, especially for license formats designed for scalability.
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.
We have not encountered any issues with missing network items or errors in API and webhook interactions.
The stability of Tenable Nessus is extraordinary.
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.
This is Tenable's property. They want to sell Tenable Security Center, and they closed all the API capability for Tenable Nessus Professional.
An AI feature that helps them discover options without requiring them to deep dive into all features or guides them through advisory functions would be beneficial.
The documentation is not well-organized, which can be confusing when searching for solutions or specific information related to Tenable Nessus Professional.

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.
I mostly use the configuration audit feature for the audit configuration as a scan policy, and I will use it for credential audit, which helps me scan credentials access such as local administrator or root access, performing a deeper and more accurate check of local configuration settings and file systems, making it a highly recommended feature.
The scanning and reporting features are the most valuable aspects of Tenable Nessus.
The most valuable features of Tenable Nessus include its ease of access and quick usability.
