Featured Reviews

Israel Cavazos Landini - PeerSpot reviewer
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 - PeerSpot reviewer
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.
HarshBhardiya - PeerSpot reviewer
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The user interface of Tenable Nessus feels outdated and could be more user-friendly.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

"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."
"We saw benefits from Zafran Security almost immediately after deploying it."
"Zafran has become an indispensable tool in our cybersecurity arsenal."
"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 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."
"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."
"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."
"Polygraph compliance is a valuable feature. In our perspective, it delivers significant benefits. The clarity it offers, along with the ability to identify and address misconfigurations, is invaluable. When such issues arise, we promptly acknowledge and take action, effectively collaborating with our teams and the responsible parties for those assets. This enables us to promptly manage problems as soon as they arise."
"The best feature, in my opinion, is the ease of use."
"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 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."
"Makes ransomware checking and OS auditing and implementation relatively easy."
"Easy to set up vulnerability scanner with good stability and a responsive technical support team."
"The results are not that bad, but the key selling point is that it is an affordable tool set."
"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 scanning and reporting features are the most valuable aspects of Tenable Nessus."
"Nessus is good at finding out what nodes you have in place. It will then provide you a report, by node, of what the vulnerabilities are. It does it quickly and stealthfully."
"The most valuable feature of Tenable Nessus is the support it provides for any new vulnerabilities quickly."
"The most valuable features are that it's fast, it's easy to use and it provides good reports."
 

Cons

"The dashboarding and reporting functionality of Zafran Security is an area that definitely could use some improvements."
"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."
"Visibility is lacking, and both compliance-related metrics and IAM security control could be improved."
"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."
"Its integrations with third-party SIEMs can be better. That is one of the things that we discussed with them."
"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."
"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."
"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 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 have a management option after the network scanning."
"The user interface of Tenable Nessus feels outdated and could be more user-friendly."
"Nessus' reporting could be more user-friendly."
"The accuracy of the vulnerability assessment is not up to par yet, as false alarms and false positives occur often."
"The reporting is a bit cumbersome."
"Model OS costs (and its segregation schema for individual modules)."
"Tenable Nessus application device assessment is one of the top tools. However, in the application security assessment, there are other tools that provide better, and more accurate findings."
"The problems I faced with Tenable Nessus were related to its dashboard's customization capabilities and its ability to provide data to third-party sources."
 

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."
"There is an annual license required to use this solution."
"The price is okay. I would give it a seven out of ten, where one is cheap and ten is expensive."
"I rate the product's price seven or eight on a scale of one to ten, where one is low price and ten is high price."
"The solution has a single price for unlimited assets."
"Nessus Manager is not an expensive product. It has its limitations, but the pricing reflects that. We have a yearly subscription."
"We incurred a single cost for a perpetual license, although I cannot comment on the price as this is above my management level."
"The price of Tenable Nessus could improve, it is 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."
