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.

Carlos Vitrano

Cloud security director at Medallia

Provides quick visibility and significantly reduces alerts

Its integrations with third-party SIEMs can be better. That is one of the things that we discussed with them. We have integrations, for instance, with Splunk. The data that we are receiving in Splunk is huge, and it is valid because Lacework has a bunch of data that they can provide to you. However, to be able to import the data and create alerts, we needed to do some work, so integration is one of the things that they can improve. For container security, how they scan images and how they provide results is something that they need to continue improving in terms of visibility. We already have visibility to several artifacts, but they can take that to the next level and see what else they can do. There can be better integrations with CI/CD pipelines. There can be improvements in terms of how we can take action or how we can report from the number of inventories they are providing to us.

Provided increased visibility across the organization's servers

The user interface of Tenable Nessus feels outdated and could be more user-friendly. Additionally, the documentation is not well-organized, which can be confusing when searching for solutions or specific information related to Tenable Nessus Professional. The reporting feature could be improved by allowing users to create their own templates instead of relying on predefined ones.

Quotes from Members

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

Pros

"We are able to see the real risk of a vulnerability on our environment with our security tools."

"Zafran is an excellent tool."

"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."

"We saw benefits from Zafran Security almost immediately after deploying it."

"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 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 aspects are identifying vulnerabilities—things that are out there that we aren't aware of—as well as finding what path of access attackers could use, and being able to see open SSL or S3 buckets and the like."

"For the most part, out-of-the-box, it tells you right away about the things you need to work on. I like the fact that it prioritizes alerts based on severity, so that you can focus your efforts on anything that would be critical/high first, moderate second, and work your way down, trying to continue to improve your security posture."

"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."

"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."

More Lacework FortiCNAPP pros

"The initial setup is very straightforward."

"It allows me to prioritize efforts and utilize effective technical resources."

"The solution is very stable."

"It does exactly what you expect it to do, and its pricing is great. We couldn't really ask for a better deal."

"I like its ease of use. It has the script that is pre-built in it, and you just got to know which ones you're looking for."

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

"Nessus is effortless to integrate."

"The scanning and reporting features are the most valuable aspects of Tenable Nessus."

More Tenable Nessus 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 configuration and setup of alerts should be easier. They should make it easier to integrate with systems like Slack and Datadog. I didn't spend too much time on it, but to me, it wasn't as simple as the alerting that I've seen on other systems."

"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."

"A feature that I have requested from them is the ability to sort alerts and policies based on a security framework. Right now, when you go into alerts, you have hundreds and hundreds of them that you have to manually pick. It would be useful to have categories for CIS Benchmark or SOC 2 and be able to display all the alerts and policies for one security framework."

"There are a couple of the difficulties we encounter in the realm of cybersecurity, or security as a whole, that relate to potentially limited clarity. Having the capacity to perceive the configuration aspect and having the ability to contribute to it holds substantial advantages, in my view. It ranks high, primarily due to its role in guaranteeing compliance and the potential to uncover vulnerabilities, which could infiltrate the system and introduce potential risks. I had been exploring a specific feature that captured my interest. However, just yesterday, I participated in a product update session that announced the imminent arrival of this feature. The feature involves real-time alerting. This was something I had been anticipating, and it seems that this capability is now being integrated, possibly as part of threat intelligence. While anomaly events consistently and promptly appear in the console, certain alerts tend to experience delays before being displayed. Yet, with the recent product update, this issue is expected to be resolved. Currently, a comprehensive view of all policies is available within the console. However, I want a more tailored display of my compliance posture, focusing specifically on policies relevant to me. For instance, if I'm not subject to HIPAA regulations, I'd prefer not to see the HIPAA compliance details. It's worth noting that even with this request, there exists a filtering mechanism to control the type of compliance information visible. This flexibility provides a workaround to my preference, which is why it's challenging for me to definitively state my exact request."

"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."

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

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

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

More Lacework FortiCNAPP cons

"I would like to have a management option after the network scanning."

"The reporting could be improved. The reporting in Rapid7 is much better."

"In Nessus Professional, the main drawback was that we could have a single-user login password. So it could be better in terms of security."

"We'd like to see the solution embrace more user-friendliness."

"The integration part is not good because five years ago, Tenable Nessus had more integration capability. After that, Tenable changed their policies and strategy."

"Tenable Nessus is not feasible for a large company."

"One significant drawback we encounter is the tool's tendency to flag patched packages incorrectly. For instance, if a package is patched by Debian maintainers but not updated to a major or minor version, Nessus may still flag it as vulnerable based on its database. This discrepancy leads to false alarms and requires our developers, system admins, and DevOps teams to address them."

"It wasn't very clear how the scripts are running the scans. There's information about the script but it's not straightforward. The script information for each of the plugins should be available, but it doesn't give us straightforward direct information about how it was executed. That needs to be more clear."

Pricing and Cost Advice

Information not available

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

"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."

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

"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."

"The cost is around $4,300 per year. Use is unlimited. You don't pay more if you want to use it for another IP."

"Tenable Nessus needs to be licensed. We own a license for the security center and that license is charged by the number of IP addresses that you can scan. You're allowed to have as many scanners as you want and there's no license for the number of scanners. We have a bunch of Nessus scanners out there, and as long as we're comfortable with staying under that IP address limit, that's really all we have to be concerned about."

"In general, it is extremely expensive."

"Its pricing is great and can't be improved. It is very cheap. It is less than 2,000 pounds a license, and you can't really ask for more. It has unlimited IPs and unlimited scans. There are no particular pricing constraints. The only additional cost is the inherent cost of the people to actually review the actual scans."

"The price of the solution is reasonable."

"The product pricing is dynamic and varies based on the specific needs of each project and customer."

"The price of Tenable Nessus is too expensive for each service center."

"I think the price is fairly affordable. It provides a license that is fair."
