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.
Nicki Møller - PeerSpot reviewer
Enables automation and quick access to necessary information
One of the significant challenges Qualys is discovery, which I know Microsoft excels at. I can't recall how well Qualys performs this function; it seems I might be missing some details. However, if there's one key aspect to focus on, it's discovery—the ability to identify assets that you are not aware of, even when you can see they are present. Understanding what those assets are is crucial. With Qualys CyberSecurity Asset Management, it was very difficult to extract detections from the system. The features within Qualys are limited to what they have developed. Sometimes a complete overview is needed to push to a Power BI dashboard, Splunk, ServiceNow, or other platforms. The export process is incredibly challenging. We needed a developer to write a hundred-line Python script that would loop over certain assets due to export limitations. Qualys CyberSecurity Asset Management could improve its integration capabilities. While it generates substantial data, correlating it with other data sources can be challenging. The export process is difficult, and pre-built integrations with other tools could be enhanced for better process implementation.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"Zafran has become an indispensable tool in our cybersecurity arsenal."
"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."
"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."
"The product's stability is very high...The scalability of the product is amazing."
"A valuable feature is the ease of management and integration with Microsoft products."
"The product’s most valuable features are compliance, recommendations, and inventories."
"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 solution is up-to-date and helps prevent zero-day attacks."
"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."
"Microsoft Defender Vulnerability Management provides regular advisories and recommendations that help improve our security posture."
"We have a diverse organization with a robust infrastructure of more than 300,000 assets. By creating unauthorized lists and rules in the Qualys CSAM module, I can block certain software from being used in the organization."
"The support is extremely helpful, deserving a 10 out of 10 rating."
"I would rate Qualys CSAM a ten out of ten."
"I would rate the Qualys CSAM a ten out of ten for its overall performance."
"My favourite feature of Qualys CyberSecurity Asset Management is its ability to target missing software."
"Authorized and unauthorized software visibility is the best feature for me. It helps me understand security controls on our network and where we lack visibility. With a single security tool, we are able to get an extensive list."
"Authorized and unauthorized software visibility is the best feature for me."
"When you implement a dynamic tag using a query, you do not need to manually tag all the servers. It categorizes all the servers that come under that query. The tagging part is automatically done within a few minutes. It reduces the effort."
 

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."
"The dashboarding and reporting functionality of Zafran Security is an area that definitely could use some improvements."
"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 product is not stable; it is very resource-intensive, consuming a lot of memory and CPU, which makes it slow."
"We have experienced some logging issues, including a few hours of downtime initially. Despite this, I would rate the overall stability as an eight."
"The technical support takes too much time to resolve tickets."
"Regarding Microsoft's technical support, I would rate it a three out of ten; they could be more responsive and knowledgeable."
"It is expensive."
"The general support 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."
"Some areas that would be helpful are more comprehensive tagging and the ability to set up better dynamic rules."
"The scanning function could be improved."
"In my opinion, the area that needs improvement is the role-based access control (RBAC). The access privilege management needs to be more robust and streamlined to enhance user access management."
"Currently, in the EASM module, the scan frequency is limited to once daily, but allowing end users control over scan scheduling would be advantageous."
"Integration of Qualys CyberSecurity Asset Management, particularly with ServiceNow, takes a very long time, and it needs prioritization of patch rules based on vulnerability risk."
"Further research and development are needed to enhance integration with other cloud agents and products, particularly improving communication with external products and vendors."
"The UI needs improvement as it can become overwhelming after prolonged use."
"The deployment is somewhat complicated and could be made more user-friendly for most users. It is currently not user-friendly for all users. It is good but can be improved. It is a new product, and they are working on it."
