With our vulnerability management platform, I used to get reports weekly, but with Vulcan Cyber, I get them daily.
Our security team probably spends 15 minutes instead of two hours daily notifying the teams.
We received support within one to three hours.
Whenever any issue arises, we contact the support, and they are always there for us.
The technical support is good yet could improve in terms of response time.
We do not necessarily have visibility of when those feature requests are going into the development pipeline.
It would enhance my experience if Vulcan informed customers of forthcoming maintenance or changes that might cause website downtime.
Their technical support team is very good, knowledgeable, and helpful.
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.
We have a lot of assets under management, and it effectively scales up to accommodate hundreds or even thousands of assets.
I'd rate the scalability ten out of ten.
I would rate it ten out of ten for scalability, as integration with multiple connectors is possible without exceeding licensing limits.
We have not encountered any issues with missing network items or errors in API and webhook interactions.
The stability of Tenable Nessus is extraordinary.
It would be better if Vulcan notified me, the customer, about upcoming maintenance or changes, indicating when the website might be down.
The product's stability is commendable, with no noticeable lags or slowness.
I would rate it a nine out of ten in terms of stability.
This is Tenable's property. They want to sell Tenable Security Center, and they closed all the API capability for Tenable Nessus Professional.
The documentation is not well-organized, which can be confusing when searching for solutions or specific information related to Tenable Nessus Professional.
The product's pricing has roughly tripled within the last couple of years, making us reconsider renewing the license for the scanner.
It would be beneficial if the platform allowed remote access to devices for immediate remedies.
Providing real-world examples of how to construct a ticket format for Jira, Azure DevOps, or ServiceNow with specific examples would help us understand how it might work in our environment.
Having it more customized or providing more customization options for me would be beneficial.
The pricing for Tenable Nessus has increased significantly, tripling over the last few years.
Tenable Nessus's pricing is adequate if it is fully utilized.
My experience with the pricing, setup cost, and licensing of Tenable Nessus is that the installation is somewhat easier, but preparing the product, such as the SKU and license options, is quite tricky.
For our use case, the solution is lacking some features, and the cost savings don't make it worth it.
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.
It offers a comprehensive view of the assets and their associated vulnerabilities, which aids in assessing and mitigating threats.
The automation capabilities using the Vulcan API platform or the API feature allow me to easily automate scripts and reports and schedule them.
Instead of having 100 vulnerabilities and not knowing how to prioritize and assign all your FTEs there, you now have only ten that you know you need to fix, and you're assigning the right number of FTEs.
