Has become an indispensable tool in our cybersecurity arsenal

While Zafran Security is already a powerful tool, there are areas where it could be further improved to provide even greater value. One key area for enhancement is the searching capabilities within its vulnerabilities module. By incorporating the ability to create Boolean searches, users would gain the ability to apply more complex filters and customize their search criteria. This would greatly enhance the precision and efficiency with which security teams can identify and prioritize vulnerabilities. Having such tailored search capabilities would save time and resources by narrowing down vast lists of vulnerabilities to those that meet specific parameters relevant to our unique risk environment. Additionally, integrating more robust reporting and visualization tools would be advantageous. Enhanced dashboards that offer customizable visual representations of risk configurations and threat landscapes would facilitate better communication with stakeholders, making it easier to explain vulnerabilities and the rationale behind certain security measures. This would also aid in demonstrating the improvements and value derived from existing security investments to leadership and non-technical team members.

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 Armis pros

It looks at your traditional environment, which is pretty much anything that is on-premises, and it also goes a step ahead and covers your modern assets, which is anything that is currently sitting in the cloud. You get complete visibility of your entire environment and tech operation. The ability to give you visibility across the entire tech surface is one of the biggest advantages that Tenable.io has."

"I would rate Tenable's dashboards and reporting capabilities for illustrating security posture a nine out of ten, with ten being the best."

More Tenable Vulnerability Management pros

Cons

"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."

"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."

"The solution's vulnerability testing could be improved."

"We face difficulties in integrating the product with ticketing tools like ServiceNow."

"Like any IT tool, continuous learning and improvement are essential for the solution."

"We have faced issues with the tool's stability."

"There isn't anything specific that needs improvement."

"Armis could improve its geographic spread and marketing campaigns across regions."

"The user interface could be improved by being able to change the user interface to fit your position or your job. The graphs are set in stone and you can only print reports."

"The solution seems to focus too much on enterprises, and they really need a product that works for SMBs."

"Tenable could improve visibility into assets, including automated asset tagging. You should be able to automatically tag assets based on location, function, ownership, etc. That would help us because we spend a lot of time identifying and tagging assets by hand."

"I would like the solution to cover the whole cycle of mitigation since it's an area where the solution currently lacks."

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

"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 solution is a bit slow."

"They should include better customization of the dashboard, and integration tools."
