Featured Reviews

Israel Cavazos Landini - PeerSpot reviewer
Weekly insights and risk analysis facilitate informed security decisions
I appreciate the weekly insights Zafran provides, which include critical topics for networks and IT security, allowing us to evaluate which insights apply to our environment. The organization score feature is valuable to keep the leadership team updated on how our infrastructure fares security-wise. The applicable risk level versus base risk level feature is beneficial because prior to Zafran, we only used the base risk level, but now understand that risk depends on the asset itself. Zafran is an excellent tool.
NaySan @ Suraj Verma - PeerSpot reviewer
Provides actionable vulnerability insights and recommendations with notable efficiency
They may need to improve the portal refresh rate for Microsoft Defender Vulnerability Management because it takes time for recommendations to disappear after mitigation; sometimes, it takes one week, when it should ideally take only one to two hours. Overall, everything is good with Microsoft Defender Vulnerability Management, but the portal refresh rate can take up to seven days in some cases and three or four days in others to reflect changes.
Chethan Gowda - PeerSpot reviewer
Have maintained accurate vulnerability scans and gained actionable remediation insights across thousands of servers
Tenable Vulnerability Management agents are very lightweight, and the results we get are very accurate. The solutions they provide to us, assuming if one vulnerability exists, there will be a solution. The resolution they give us in wording will be the best solution. The exploit rates and the reports we get provide a lot of information, making it very easy for us to verify.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. That is one of the key aspects of why we have integrated Tenable to our patching tools. It has a vast capacity of pushing the data to our tools due to its capability and compatibility. That is also one of the reasons why we are using Tenable Vulnerability Management.

Pros

"We are able to see the real risk of a vulnerability on our environment with our security tools."
"We saw benefits from Zafran Security almost immediately after deploying it."
"Zafran is an excellent tool."
"Overall, we have seen about eighty-seven percent reduction of the number of vulnerabilities that require urgency to remediate, specifically the number of criticals."
"Zafran has become an indispensable tool in our cybersecurity arsenal."
"Microsoft Defender Vulnerability Management is a good product, and I believe it deserves a positive recommendation."
"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 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."
"Microsoft Defender Vulnerability Management is versatile and assesses vulnerabilities, providing detailed information on CVEs, their categories, and exploit statuses."
"The integration with Sentinel has been one of the most valuable features for my organization."
"The solution helps identify threats and vulnerabilities."
"Overall, I would rate Microsoft Defender Vulnerability Management a nine out of ten."
"Microsoft Defender Vulnerability Management provides regular advisories and recommendations that help improve our security posture."
"The integration of Tenable into our security ecosystem was very good."
"The price of Tenable.io Vulnerability Management is reasonable as it is ten times cheaper than other options."
"The solution is quite friendly."
"The tool has an easy-to-use interface."
"The best feature of the solution is the amount of visibility it provides of the vulnerabilities."
"There is no burden of updating or upgrading this solution."
"It's a recommended tool for penetration testers because it's effective for that purpose."
"One of the most valuable features of Tenable.io Vulnerability Management is its exportability, which allows us to conduct risk assessments efficiently."
 

Cons

"I think the ability to have some enhanced reporting capabilities is something they can improve on, as they have good reports but we have asked for some specific reporting enhancements."
"Initially, we were somewhat concerned about the scalability of Zafran due to our large asset count and the substantial amount of information we needed to process."
"The dashboarding and reporting functionality of Zafran Security is an area that definitely could use some improvements."
"It is expensive."
"There should be risk scoring added to Microsoft Defender Vulnerability Management; specifically, they call it quantification of the risk."
"Regarding Microsoft's technical support, I would rate it a three out of ten; they could be more responsive and knowledgeable."
"Sometimes the stability of the agents could be improved."
"The setup phase of the product is not that easy and needs a person to have a certain level of expertise."
"Probably my only criticism would be the cost. It is expensive."
"It is challenging to extract and customize reports from the system."
"Integration can be improved."
"I would evaluate Tenable Vulnerability Management's customer service and technical support as average."
"The only drawback of the solution is that it is expensive."
"They've been able to think about everything in terms of where the world is going and the type of assets that you've got. They've everything sorted out in that aspect, but you have to pay for most of the other components that they've got to give you complete visibility across your tech surface. If it already had those capabilities in-built, without having to add them on to take advantage of them, it would be a very compelling value proposition."
"The reporting was never great in Tenable Vulnerability Management, so, in my company, we imported all the data into Ivanti RiskSense to start using it for reporting."
"The interface could be improved; right now it's running on two interfaces simultaneously."
"Tenable.io Vulnerability Management could be improved with an increased number of dashboards and MSSP integration."
"AI integration for reporting in Tenable would be beneficial."
"The pricing of the solution could be more reasonable."
