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

"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, as well as some levels of machine learning anomaly detection that they have that can detect pivotal anomalies faster."
"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 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 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."
"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."
"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."
"It is a scalable solution. Scalability-wise, it is a good solution."
"The solution shows you the exploitable vulnerabilities and helps you prioritize."
"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."
"The strong security provided by the product in the container environment is its most valuable feature."
 

Cons

"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 vulnerability part is not systematically organized; it is all clumsy in the web UI, and it is not user-friendly."
"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."
"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."
"In general, I would not recommend Lacework right now. There are more mature solutions that would be a better fit."
"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 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."
"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."
"The initial setup is highly complex."
"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."
"I feel that in certain areas this product has false positives which the company should work on."
"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."
"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."
 

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 product’s pricing a six out of ten."
"I rate the tool's pricing a three out of ten."
"The product does not operate on a pay-per-license model."
"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."
