Network segmentation has strengthened access control and now streamlines automated threat response
The most valuable features in FortiCNAPP include robust network segmentation and restricting access to network assets. It also supports security measures by leveraging security fabrics for better enforcement and policy enforcement. FortiCNAPP integrates with SIEM solutions, and we offer different SIEM options that work with Fortinet and AlienVault, among others, providing multiple scenarios.FortiCNAPP's automated policy recommendations significantly help improve security measures as part of an overall service wrap. When deploying a Fortinet SD-WAN or network, these tools provide greater visibility to vulnerabilities and enhanced security on the network. It functions as a proactive tool, enabling me to identify threats quickly and automate responses.

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 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."
"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 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."
"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 best feature, in my opinion, is the ease of use."
"FortiCNAPP definitely brings time-saving benefits, and security is the main concern for the company."
"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 machine learning capability in Lacework FortiCNAPP is used for threat detection, and automated policy recommendation helps to improve my security measures in general."
"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."
"The solution shows you the exploitable vulnerabilities and helps you prioritize."
"The tool's most valuable feature is scanning, reporting, and troubleshooting."
"Most valuable are the reports that are quite good, particularly the detailed ones for container image scanning."
"It helps us secure our applications from the build phase and identify the weaknesses from scratch."
"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."
"Nessus scanner is very effective for internal penetration testing."
"The strong security provided by the product in the container environment is its most valuable feature."
 

Cons

"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."
"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."
"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."
"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."
"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."
"Policy implementation is quite complex, and the stability will take more time for the solutions."
"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 support is tricky to reach, so we would like better-oriented technical support enabled."
"The initial setup is highly complex."
"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."
"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."
"Tenable.io Container Security should improve integration modules. It should also improve stability."
"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."
"I believe integration plays a crucial role for Tenable, particularly in terms of connecting with other products and various container solutions like Docker or Kubernetes. It seems that in future updates, enhanced integration is something I would appreciate. Currently, there is integration with Docker, but when it comes to Kubernetes or other container solutions, it appears to be a challenge, especially with on-prem scanners."
 

Pricing and Cost Advice

"My smaller deployments cost around 200,000 a year, which is probably not as expensive as Wiz."
"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 licensing fee was approximately $80,000 USD, per year."
"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 product does not operate on a pay-per-license model."
"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."
"I rate the product’s pricing a six out of ten."
"The solution's pricing is neither cheap nor very expensive."
"I rate the tool's pricing a three out of ten."
