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.
OndrejKOVAC - PeerSpot reviewer
Empower clients with risk-based vulnerability management through continuous workflow and valuable insights
Tenable Security Center could improve by implementing more dynamic data displays and translating reports into European languages. This is especially relevant in Central Eastern Europe, where clients often require reports in local languages. Additionally, the licensing model could be more flexible for managed security providers, similar to a pay-as-you-go model.

Quotes from Members

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

Pros

"We saw benefits from Zafran Security almost immediately after deploying it."
"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."
"Zafran is an excellent tool."
"We are able to see the real risk of a vulnerability on our environment with our security tools."
"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."
"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."
"Microsoft Defender Vulnerability Management is a good product, and I believe it deserves a positive recommendation."
"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."
"The solution is highly scalable."
"The product's stability is very high...The scalability of the product is amazing."
"The integration with Sentinel has been one of the most valuable features for my organization."
"My advice for those considering Tenable Security Center is to note the benefit of upgrading vulnerable devices."
"The tool gives us fewer false positives. Compared to its competitors, the solution’s reports are more accurate."
"One of the most valuable features is their distributed scan model for allotting engines to work together as a pool and handle multiple scans at once, across multiple environments. Automatic scanning distribution is a distinguishing feature of their toolset."
"Their overall cost of service is pretty good."
"Tenable SC is good for reporting and alerting. The filtering feature is also very valuable. Its integration with multiple vendors is quite good. It can be integrated with SIEM solutions and PAM solutions such as Thycotic, which is very helpful."
"The scanning part, the agent part – that's the valuable aspect."
"The initial setup process is simple."
"This solution has a much lower rate of false positives compared to competing products."
 

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."
"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."
"The constant changes in the product configuration or the console setup can sometimes be challenging."
"The automated remediations can be more specific."
"The setup phase of the product is not that easy and needs a person to have a certain level of expertise."
"Sometimes the stability of the agents could be improved."
"It is expensive."
"The worst aspect is the refresh rate of the dashboard."
"Regarding Microsoft's technical support, I would rate it a three out of ten; they could be more responsive and knowledgeable."
"The web application scanning area can be improved."
"Tenable's technical support has declined in quality over time. While they used to be excellent, achieving ratings of eight or nine, they now rate around six or seven due to longer response times and less thorough assistance."
"The solution needs to improve the vulnerability assessment because we have experienced some challenges with accuracy."
"Tenable.sc's user interface could be improved."
"The reports and plugins for reports and scans could benefit from enhancements."
"It's good at creating information, it's good creating dashboards, it's good at creating reports, but if you want to take that reporting metadata and put it into another tool, that is a little bit lacking."
"The integration is very good, although it still needs to improve."
"We are facing some challenges related to our channel."
