Tenable Nessus and Microsoft Defender Vulnerability Management compete in vulnerability assessment and management. Microsoft Defender Vulnerability Management has an edge due to its feature richness and cost-effectiveness.
Features: Tenable Nessus offers extensive scanning, detailed reporting, and supports a wide range of devices. Microsoft Defender Vulnerability Management integrates well with the Microsoft ecosystem, enhances endpoint protection, and supports seamless workflows for Microsoft users.
Room for Improvement: Tenable Nessus could improve its integration capabilities with non-Tenable ecosystems, enrich its user interface experience, and expand its automation tools. Microsoft Defender Vulnerability Management might benefit from decreasing integration setup time for non-Microsoft users, enhancing support for diverse operating systems, and refining its pricing model for cost-effectiveness.
Ease of Deployment and Customer Service: Tenable Nessus is straightforward to set up with available customer support, offering quick, independent deployment. Microsoft Defender Vulnerability Management integrates smoothly within existing Microsoft environments, easing deployment for current Microsoft customers, but may require more setup for others.
Pricing and ROI: Tenable Nessus provides competitive pricing and immediate affordability with effective vulnerability detection and reporting. Microsoft Defender Vulnerability Management has higher initial costs but offers long-term ROI through added security features and integration benefits for businesses invested in Microsoft technologies.
Organizations typically do not rely solely on Microsoft products to avoid putting all eggs in one basket, which presents a challenge for maximizing ROI.
As a Microsoft partner, we receive significant discounts, making the solution affordable for us.
They are sometimes responsive, however, often issues cannot be reproduced on their end, making it challenging.
The support we receive from Microsoft is declining, and for example, after taking advanced support, we have not received satisfactory answers.
They are familiar with Microsoft products but are not direct Microsoft staff, which is an area needing improvement.
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.
The integration is straightforward for those who understand it, though documentation needs improvement.
It is scalable; I evaluated the product and decided to use Defender on over 700 of our company servers.
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.
There are compatibility issues occasionally arising with false positives when other security tools are not whitelisted in Microsoft Defender.
It is very resource-intensive, consuming a lot of memory and CPU.
If Microsoft experiences downtime, this solution goes down as it is a SaaS-based solution where we have no control.
We have not encountered any issues with missing network items or errors in API and webhook interactions.
The stability of Tenable Nessus is extraordinary.
This scoring should be for specific industries as well. If I belong to the healthcare industry using Microsoft Defender Vulnerability Management, it should provide me with a risk score and show how I fare against the risk score of my industry.
A vulnerability I patch within 15 minutes takes 24 additional hours for an update.
The product is not stable; it often uses excessive memory and CPU, which makes it slow.
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.
Overall, every organization wishes for cheaper options, but we look at the security side as well, so we are good for now.
For non-partners, however, the cost could be seen as higher, between seven to ten.
The pricing is reasonable, and it's included in the whole Microsoft E5 bundle, so it's all-inclusive.
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.
The main advantage of Microsoft Defender Vulnerability Management is that it can locate and prevent most threats even when the endpoints are not connected to the corporate network, as long as the internet is available.
The feature for customizing to region-specific and domain-specific requirements in healthcare is particularly beneficial.
The most valuable aspect is the kind of assessment results I get, and the recommendations provided in Microsoft products really help in taking care of the resources.
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.
