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.

Immediate results in patching promptly address vulnerabilities
When working with Tanium, there are some older devices that haven't been patched for a long time, and certain patches are not included in Tanium. I have to search outside to download patches, create bundles, and then perform the task. It would be easier if Tanium provided the patches directly. Some other brands provide the patch with a direct download link, which facilitates the process. Also, I feel that if there were more detailed documents and remediations readily available online for troubleshooting, especially more up-to-date information, it would be beneficial. Currently, some resources online are very out-of-date.

Has enabled me to reduce false positives and perform deep credential auditing with seamless integrations
I mostly use the configuration audit feature for the audit configuration as a scan policy, and I will use it for credential audit, which helps me scan credentials access such as local administrator or root access, performing a deeper and more accurate check of local configuration settings and file systems, making it a highly recommended feature. Regarding integration capabilities, we can integrate Tenable Nessus with SIM tools such as Splunk, IBM QRadar, and Azure Sentinel, as well as with ticketing systems such as ServiceNow, Jira, and Slack. There is no complexity as it is very easy to integrate everything. In terms of the reporting feature, while vulnerability scanning can throw some false positives, Tenable Nessus has very few, achieving a reduction of 75% to 80% false positives with manual analysis needed. We can generate standard Nessus reports that typically include host summaries and vulnerabilities by host and plugin, alongside solutions and remediation recommendations. The main benefits I get from Tenable Nessus are complete asset inventory and comprehensive attack surface management, allowing us to prioritize vulnerabilities based on risk, focusing on true risk and threat path analysis.

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."
"We saw benefits from Zafran Security almost immediately after deploying it."
"With Zafran Security, it integrates with your security controls, allowing you to take that risk score and reduce it based on the controls in place or increase the risk based on different factors, such as if the issue is internet reachable or if there's an exploit in the wild."
"Zafran is an excellent tool."
"We are able to see the real risk of a vulnerability on our environment with our security tools."
"Overall, we have seen about eighty-seven percent reduction of the number of vulnerabilities that require urgency to remediate, specifically the number of criticals."
"I'm not so familiar with the tool but I like the interaction of the console to the picture. Patching is the primary model I have been focusing on for the last couple of weeks. So I have created a proof of concept environment and have been checking the available features."
"Tanium is a very good product and I would rate it eight or nine out of ten."
"Tanium's most valuable features are patch management, inventory, and distribution software."
"The product is granular and can build complex roles compared to other EDR vendors."
"When I push a quick update, it's done right away, and I can rescan immediately to confirm completion within minutes."
"When I push a quick update, it's done right away, and I can rescan immediately to confirm completion within minutes."
"Tanium’s best features include support for any Windows, Linux, or Mac endpoint, regardless of where it is, and the ability to do IT operations and security operations."
"I like the tool's incident response and security patching."
"Tenable Nessus is one of the best vulnerability assessment tools, that I know."
"Ease of reviewing scores, identifying vulnerabilities, and getting information on them."
"The support has been really cooperative."
"The plug-in text information is quite useful."
"The stability is very good."
"The most valuable feature of Tenable Nessus is vulnerability detection."
"The most valuable feature of Tenable Nessus is the self-updating engine."
"The results are not that bad, but the key selling point is that it is an affordable tool set."
 

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."
"Tanium's limitations should be improved because although it is a great tool, it is limited to only a few classes during a session."
"We had some issues with the solution's OS upgrade."
"I would like to have more integrations and custom plugins to input. Integration is always a big deal in a lot of different environments."
"The solution lacks mobility."
"The performance could improve in future releases. We have had performance issues in specialized web environments, but overall I think the problems are less than 2% of the computer systems being used."
"Tanium required local admin or root rights on Mac devices, which did not comply with our security policies. This made the solution less suitable for our restrictive environment."
"The solution needs to improve the reporting and tracking capabilities."
"They could improve the UI."
"The features are limited when it comes to scanning network devices for vulnerabilities."
"Sometimes, the categorization for clients was tricky at first, however, they eventually got used to it."
"It would be nice for the professional module to include some of the reports available in the expert module."
"We would like to have the option of using the solution for the cloud as well as on-premises with the same license at the same time. That would be very helpful."
"Vulnerability recommendations are outdated and not in line with industry standards."
"We have had some false positives in the past, which we hope can improve in the future."
"Tenable Nessus could improve the reporting by adding some dashboards. The reports are a hassle at this time. Tenable.io has more detailed reports. Having a better dashboard that can show where the vulnerabilities are and be categorized would be helpful. We then could present them to upper management for a deep overview of our network posture which they do not see."
"The price could be more reasonable. I used the free Nessus version in my lab with which you can only scan 16 IP addresses. If I wanted to put it in the lab in my network at work, and I'm doing a test project that has over 30 nodes in it, I can't use the free version of Nessus to scan it because there are only 16 IP addresses. I can't get an accurate scan. The biggest thing with all the cybersecurity tools out there nowadays, especially in 2020, is that there's a rush to get a lot of skilled cybersecurity analysts out there. Some of these companies need to realize that a lot of us are working from home and doing proof of concepts, and some of them don't even offer trials, or you get a trial and it is only 16 IP addresses. I can't really do anything with it past 16. I'm either guessing or I'm doing double work to do my scans. Let's say there was a license for 50 users or 50 IP addresses. I would spend about 200 bucks for that license to accomplish my job. This is the biggest complaint I have as of right now with all cybersecurity tools, including Rapid7, out there, especially if I'm in a company that is trying to build its cybersecurity program. How am I going to tell my boss, who has no real budget of what he needs to build his cybersecurity program, to go spend over $100,000 for a tool he has never seen, whereas, it would pack the punch if I could say, "Let me spend 200 bucks for a 50 user IP address license of this product, do a proof of concept to scan 50 nodes, and provide the reason for why we need it." I've been a director, and now I'm an ISO. When I was a director, I had a budget for an IT department, so I know how budgets work. As an ISO, the only thing that's missing from my C-level is I don't have to deal with employees and budgets, but I have everything else. It's hard for me to build the program and say, "Hey, I need these tools." If I can't get a trial, I would scratch that off the list and find something else. I'm trying to set up Tenable.io to do external PCI scans. The documentation says to put in your IP addresses or your external IP addresses. However, if the IP address is not routable, then it says that you have to use an internal agent to scan. This means that you set up a Nessus agent internally and scan, which makes sense. However, it doesn't work because when you use the plugin and tell it that it is a PCI external, it says, "You cannot use an internal agent to scan external." The documentation needs to be a little bit more clear about that. It needs to say if you're using the PCI external plugin, all IP addresses must be external and routable. It should tell the person who's setting it up, "Wait a minute. If you have an MPLS network and you're in a multi-tenant environment and the people who hold the network schema only provide you with the IP addresses just for your tenant, then you are not going to know what the actual true IP address that Tenable needs to do a PCI scan." I've been working on Tenable.io to set up PCI scans for the last ten days. I have been going back and forth to the network thinking I need this or that only to find out that I'm teaching their team, "Hey, you know what, guys? I need you to look past your MPLS network. I need you to go to the edge's edge. Here's who you need to ask to give me the whitelist to allow here." I had the blurb that says the plugin for external PCI must be reachable, and you cannot use an internal agent. I could have cut a few days because I thought I had it, but then when I ran it, it said that you can't run it this way. I wasted a few hours in a day. In terms of new features, it doesn't require new features. It is a tool that has been out there for years. It is used in the cybersecurity community. It has got the CV database in it, and there are other plugins that you could pass through. It has got APIs you can attach to it. They can just improve the database and continue adding to the database and the plugins to make sure those don't have false positives. If you're a restaurant and you focus on fried chicken, you have no business doing hamburgers."
