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.

Improving security insights has been helpful but inconsistent vulnerability tracking needs attention

The vulnerability part is not systematically organized; it is all clumsy in the web UI, and it is not user-friendly. Regarding improvements, the vulnerability part, recent changes with user management, and Fortinet IM coming into place, which is not helpful at all because it cuts out the automation part, are the most important things. Lacework FortiCNAPP should have a new clean UI and ease of access for the users as that should be the main concern. There are limitations regarding the scalability of Lacework FortiCNAPP. There are also more limitations with integrations like GitHub or any other pipeline, CI/CD, or ISD. It is glitchy and works well only sometimes, and most of the time, the reports or other things are not properly calculated or circulated with the teams.

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."

"Zafran is an excellent tool."

"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."

"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."

"The most valuable feature, from a compliance perspective, is the ability to use Lacework as a platform for multiple compliance standards. We have to meet multiple standards like PCI, SOC 2, CIS, and whatever else is out there. The ability to have reports generated, per security standard, is one of the best features for me."

"The most valuable feature is Lacework's ability to distill all the security and audit logs. I recommend it to my customers. Normally, when I consult for other customers that are getting into the cloud, we use native security tools. It's more of a rule-based engine."

"There are many valuable features that I use in my daily work. The first are alerts and the event dossier that it generates, based on the severity. That is very insightful and helps me to have a security cap in our infrastructure. The second thing I like is the agent-based vulnerability management, which is the most accurate information."

"The best feature, in my opinion, is the ease of use."

"The machine learning capability in Lacework FortiCNAPP is used for threat detection, and automated policy recommendation helps to improve my security measures in general."

"Lacework is helping a lot in reducing the noise of the alerts. Usually, whenever you have a tool in place, you have a lot of noise in terms of alerts, but the time for an engineer to look into those alerts is limited. Lacework is helping us to consolidate the information that we are getting from the agents and other sources. We are able to focus only on the things that matter, which is the most valuable thing for us. It saves time, and for investigations, we have the right context to take action."

"The compliance reports are definitely most valuable because they save time and are accurate. So, instead of relying on a human going through and checking or providing me with a report, I could just log into Lacework and see for myself."

"I find the cloud configuration compliance scanning mature. It generates a lot of data and supports major frameworks like ISO 27001 or SOC 2, providing reports and datasets. Another feature I appreciate is setting custom alerts for specific events. Additionally, I value the agent-based monitoring and scanning for compute nodes. It gives us deeper insights into our workloads and helps identify vulnerabilities across our deployed assets."

More FortiCNAPP pros

"The initial setup of Tenable Nessus is very easy."

"Tenable Nessus has provided increased visibility across the organization's servers."

"The vulnerability scanner is the most valuable feature."

"Tenable Nessus has a good performance, is very user-friendly, and is easy to use."

"The most valuable feature of Tenable Nessus is the GUI and user-friendliness. Additionally, the environment is easy to work with."

"The solution is great for scanning servers."

"My favorite part about Nessus is that you can customize the tool to scan exactly what you want. Microsoft releases new patches monthly on Patch Tuesday, and a lot of companies track that date. I set up Nessus for the day after Patch Tuesday to see which devices have already pushed those updates from Microsoft, so we can stay updated."

"You can then direct your team to create a report on the discovered vulnerabilities."

More Tenable Nessus pros

Cons

"The dashboarding and reporting functionality of Zafran Security is an area that definitely could use some improvements."

"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 biggest thing I would like to see improved is for them to pursue and obtain a FedRAMP moderate authorization... I don't believe they have any immediate plans to get FedRAMP moderate authorized, which is a bit of a challenge for us because we can only use Lacework in our commercial environment."

"Lacework has not reduced the number of alerts we get. We've actually had to add resources as a result of using it because the application requires a lot of people to understand it to get the value out of it properly."

"Visibility is lacking, and both compliance-related metrics and IAM security control could be improved."

"I would like to see a remote access assistance feature. And the threat-hunting platform could be better."

"Lacework lacks remediation features, but I believe they're working on that. They're focused on the reporting aspect, but other features need to improve. They're also adding some compliance features, so it's not worth saying they need to get better at it."

"Its integrations with third-party SIEMs can be better. That is one of the things that we discussed with them."

"The vulnerability part is not systematically organized; it is all clumsy in the web UI, and it is not user-friendly."

"The solution lacks a cohesive data model, making extracting the necessary data from the platform challenging. It uses its own LQL query language, and each database across different layers and modules is structured differently, complicating correlation efforts. Consequently, I had to create extensive custom reports outside Lacework because their default dashboards didn't communicate risk metrics. They're addressing these issues by redesigning their tools, including introducing the dashboard, which is a step closer to actionable insights but still needs refinement."

More FortiCNAPP cons

"It would be better if they had application-level support for mobile devices. They don't have anything to scan mobile devices. Tenable Nessus doesn't have a mobile application vulnerability assessment. I also have issues with the false positive rates. The product has limited features."

"The solution could improve by having better integration with different vendors' IPS solutions. The ACLs and IPS policies signatures should be enabled based on the results of Tenable Nessus automatically, we currently have to do it manually which is very time-consuming. It has done a good job integrating with Fortinet but we would like it to be better integrated with other solutions that we have."

"The reporting feature needs to be improved."

"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."

"I would like to see more on the automation side."

"One area that has room for improvement is the reporting. I'm preparing reports for Windows and Linux machines, etc. Currently, I'm collecting three or four reports and turning them into one report. I don't know if it is possible to combine all of them in one report, but that would be helpful."

"The most that Tenable Nessus could improve is its speed because they might have put a lot of effort into compatibility issues that downgrade the speed."

"They should improve the I/O reporting and the customized spreadsheet export feature."

Pricing and Cost Advice

Information not available

"The pricing has gotten better. That scenario was somewhat unstable. They have a rather interesting licensing structure. I believe you get 200 resources per "Lacework unit." It was difficult, in the beginning, to figure out exactly what a "resource" was... That was a problem until about a year or so ago. They have improved it and it has stabilized quite a bit."

"It is slightly expensive. It depends on how big your environment is, but it is expensive. Right now, we are spending a lot of money. We have covered all of the cloud providers and most of our colocation facilities as well, so we cannot complain, but it is slightly expensive. It is not super expensive."

"My smaller deployments cost around 200,000 a year, which is probably not as expensive as Wiz."

"The licensing fee was approximately $80,000 USD, per year."

"The price of Tenable Nessus could improve, it is expensive."

"The price is okay. I would give it a seven out of ten, where one is cheap and ten is expensive."

"I would like to see better discounts."

"The price of the solution is reasonable."

"Cost-wise, it's an affordable tool."

"Nessus Manager is not an expensive product. It has its limitations, but the pricing reflects that. We have a yearly subscription."

"In general, it is extremely expensive."

"This solution is affordable."
