Tenable Nessus and NodeZero Platform both compete in the vulnerability management category. Tenable Nessus appears to have the advantage due to its comprehensive coverage and competitive pricing.
Features: Tenable Nessus offers predictive prioritization, customizable policies, and seamless integration with other market tools. Users value its scanning and reporting features alongside affordability. Horizon3.ai's NodeZero Platform features real-time vulnerability validation, autonomous operation, and automated penetration testing, excelling in ease of use for scanning internal and external networks.
Room for Improvement: Tenable Nessus users suggest enhanced reporting, improved UI, and better integration for cloud deployments. NodeZero users recommend quicker scan speeds, improved integration with systems, and enhanced external vulnerability detection, especially for web apps.
Ease of Deployment and Customer Service: Tenable Nessus is typically deployed in on-premises and hybrid cloud environments with satisfactory technical support, although some users note variable response times. NodeZero offers deployment flexibility, available on both public and private clouds, with praised responsiveness, though simpler report technicalities are needed.
Pricing and ROI: Tenable Nessus is praised for its competitive pricing and cost-effective licensing that provides substantial ROI, effectively preventing vulnerabilities. NodeZero's pricing is flexible but usually higher than traditional managers, with ROI enhanced by reducing manual testing costs via autonomous operation.
A reduction in remediation time has been seen because it is finding things before they happen.
Being able to find them because there have been no eyes on that particular section so far ever, and fixing those potentially prevented those companies from getting breached.
So far, I have seen a return on investment with The NodeZero Platform by Horizon3.ai, as we managed to save a lot of time and effort with this because this is an autonomous tool, and our manual effort is significantly reduced because of a product of this type.
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.
Overall, when it comes to The NodeZero Platform's tech support, you can reach them via a chat message on their website, and they respond almost immediately.
Previously, with time-sensitive engagements, I would worry about resolving issues before deadlines. That concern has diminished as they've become more responsive and require less escalation to engineering.
The vast majority of times they are able to resolve the exact questions my team has on the first attempt, which is really good for customer or technical support.
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 conducted pen tests in environments with hundreds of thousands of IP addresses without any scalability issues.
We currently scan approximately 1,500-2,000 assets and haven't encountered any scaling or throughput issues.
Anywhere you can put a VM, you can run another concurrent scan.
We have not encountered any issues with missing network items or errors in API and webhook interactions.
The stability of Tenable Nessus is extraordinary.
We have not encountered any issues on the platform regarding accessibility, performance, or stability.
Regarding stability, it has never crashed, and there has not been any lagging from deployment or running.
I would rate the stability of The NodeZero Platform by Horizon3.ai as a ten.
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 service reveals which credentials and email addresses are available on the deep web, as well as which domains have been set up using typo-squatting techniques.
The one thing that is very much asked from us as a service provider is DAST testing, so when a company is building a software, they could see their current security status while they are building the application.
One of the areas where improvement is needed is in the visibility and reporting for large enterprises.
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.
When we compare it to other solutions, it is more difficult for us to negotiate the price for Tenable Nessus than to negotiate the price with Rapid7.
The pricing is much more affordable than traditional penetration tests.
It's a bit cheaper than manual penetration testing because manual testing typically allows you to scan only a few subnets.
While cheaper than XM Cyber and human pen testers, it's more expensive than vulnerability managers.
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.
When a new vulnerability, such as a zero-day exploit, is identified, they review your previous scans to determine if you might be vulnerable to it, and they proactively notify you.
The detailed reports not only list the vulnerabilities that matter, but they also include direct links to patches.
The NodeZero Platform's real attack capabilities help in identifying vulnerabilities on our on-prem systems because it provides actual vulnerabilities by attacking our systems.
