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.

Helps with risk assessments for containers, assessing security, and ensuring container compliance

I rate the overall product a nine out of ten. Customers can conveniently view all companies in a single dashboard if they have different companies. This feature eliminates the need for different solutions and separate installations. Moreover, the solution extends beyond servers, encompassing various platforms such as VMware and Kubernetes. Additionally, end-users can install the solution from their client's perspective.

Windows Security Patching Operation III (Cyber Operations) at CBTS

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.

More Tenable Vulnerability Management pros

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."

"The product lacks network assessment capabilities. We cannot view our network assets or scan switches, routers, or IPs for vulnerabilities and issues."

"I would evaluate Tenable Vulnerability Management's customer service and technical support as average."

"They need to have more dependable and faster support."

"t needs additional reporting and intelligence features, as well as enhancements in AI-driven detection, which is still in its early stages."

"The stability has room for improvement."

"I'm not satisfied with the reporting structure."

"An area of improvement for this solution is being able to customize the dashboard. For example, the dashboard does not allow us to view a previous months vulnerability results alongside current results to make comparisons."

"The tool's reports are bad. They're not very customizable or flexible. During audits, we often have to exclude things that aren't relevant to our organization, but we can't do that easily with the reports. They come in HTML or PDF format, and we can't compare current results with previous ones in Excel because we never receive reports in Excel."

"It can have more integration."
