SK
Software Engineer at a university with 5,001-10,000 employees
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.
AS
Cyber Security Architect at a security firm with 201-500 employees
Detailed container image reports have improved vulnerability insight and support secure operations
Most valuable are the reports that are quite good, particularly the detailed ones for container image scanning. Tenable.io Container Security is giving me the vulnerability information of Docker images and the information about software bill of materials. However, my challenge at this time is that I am using all these solutions with GitLab Ultimate, and it does not support integration, so I am doing some alternate arrangements which are giving me operational complexity because I need to introduce something else instead of GitLab Ultimate. That is the primary concern regarding the benefits of real-time visibility into my containerized application security status.

Quotes from Members

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

Pros

"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."
"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 best feature, in my opinion, is the ease of use."
"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 machine learning capability in Lacework FortiCNAPP is used for threat detection, and automated policy recommendation helps to improve my security measures in general."
"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."
"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."
"It helps us secure our applications from the build phase and identify the weaknesses from scratch."
"Currently, I haven't implemented the solution due to its deprecation by the site. However, I can highlight some benefits of Tenable Cloud Security, a cybersecurity solution with various features for scanning vulnerabilities in both cloud environments and on-premises container security."
"Most valuable are the reports that are quite good, particularly the detailed ones for container image scanning."
"It is a scalable solution. Scalability-wise, it is a good solution."
"The tool's most valuable feature is scanning, reporting, and troubleshooting."
"The solution shows you the exploitable vulnerabilities and helps you prioritize."
"Tenable.io detects misconfiguration when you deploy a Docker or Kubernetes container. It's much better to remedy these issues during deployment instead of waiting until the container is already in the production environment."
"The strong security provided by the product in the container environment is its most valuable feature."
 

Cons

"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."
"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."
"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."
"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."
"I would like to see a remote access assistance feature. And the threat-hunting platform could be better."
"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."
"I feel that in certain areas this product has false positives which the company should work on. They should also try to include business logic vulnerabilities in the scanner testing. Finally, the vulnerability assessment feature should be increased to other hardware devices, apart from firewalls."
"The initial setup is highly complex."
"The stability and setup phase of the product are areas with shortcomings where improvements are needed."
"They need to work on auto-remediation so it's easier for the security team to act quickly when certain assets or resources are deployed. The latest version has a CIS benchmark that you need to meet for containers in the cloud, but more automation is needed."
"The solution’s pricing could be improved."
"However, my challenge at this time is that I am using all these solutions with GitLab Ultimate, and it does not support integration, so I am doing some alternate arrangements which are giving me operational complexity because I need to introduce something else instead of GitLab Ultimate."
"Tenable.io Container Security should improve integration modules. It should also improve stability."
"The support is tricky to reach, so we would like better-oriented technical support enabled."
 

Pricing and Cost Advice

"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."
"I rate the tool's pricing a three out of ten."
"The solution's pricing is neither cheap nor very expensive."
"It's best to be an institutional buyer and directly contact the sales team as they can provide over-the-top discounts for bulk orders."
"The product does not operate on a pay-per-license model."
"I rate the product’s pricing a six out of ten."
