Tells us about vulnerabilities as well as their impact and helps to focus on real issues
Looking at all the different pieces, it has got everything we need. Some of the pieces we do not even use. For example, we do not have Kubernetes Security. We are not running any K8 clusters, so it is good for us. Overall, we find the solution to be fantastic. There can be additional education components. This may not be truly fair to them because of what the product is going for, but it would be great to see additional education for compliance. It is not a criticism of the tool per se, but anything to help non-development resources understand some of the complexities of the cloud is always appreciated. Any additional educational resources are always helpful for security teams, especially those without a development background.
Daniel Stevens - PeerSpot reviewer
Offers easy management and container connection with HTTPS, but the support needs to improve
I have experience with the solution's setup in Rio de Janeiro, Brazil and our company has assisted in the development of a cluster in a research department, but we didn't start from scratch because we have IT professionals who have installed Kubernetes across 12 nodes of a cluster and a new environment can be created for a new platform. I also had another setup experience of Red Hat Advanced Cluster Security for Kubernetes in Portugal where I had to implement the solution in a cluster of 22 computer servers, which was completed with assistance from the IT department of the company. The initial setup process of the solution can be considered as difficult. The setup process involves using the permissions, subnets and range of IPs, which makes it complex. Deploying Red Hat Advanced Cluster Security for Kubernetes takes around eight to ten hours for new clusters. The solution's deployment can be divided into three parts. The first part involves OpenStack, where the cluster's resources need to be identified. The second part involves virtualizing assets and identifying other physical assets, for which OpenStack, Kubernetes, or OpenShift are used. The third part of the deployment involves dividing the networks into subnetworks and implementing automation to deploy the microservices using Helm. The number of professionals required for the solution's deployment depends upon the presence of automated scripts. Ideally, two or three professionals are required to set up Red Hat Advanced Cluster Security for Kubernetes.

It helps you catch misconfigurations before they go into a production environment where they're harder to deal with
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. Asset visibility is also critical. While Tenable provides visibility into containers, it could be done much better. Compliance is one of the most crucial aspects of container security. It should be more customizable. For example, I would like a rating system where Tenable reports a risk score for each container based on user-defined metrics, such as severity, activity, or compliance.

Quotes from Members

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

Pros

"When creating cloud infrastructure, Cloud Native Security evaluates the cloud security parameters and how they will impact the organization's risk. It lets us know whether our security parameter conforms to international industry standards. It alerts us about anything that increases our risk, so we can address those vulnerabilities and prevent attacks."
"I did a lot of research before signing up and doing the demo. They have a good reputation as far as catching threats early on."
"Cloud Native Security offers attack path analysis."
"PingSafe can integrate all your cloud accounts and resources you create in the AWS account, We have set it up to scan the AWS transfer services, EC2, security groups, and GitHub."
"You not only get to know about vulnerabilities and misconfigurations but also some of the actual"
"PingSafe offers an intuitive user interface that lets us navigate quickly and easily."
"Our organization is growing steadily, so our infrastructure is expanding, and we're managing more technical resources. Singularity Cloud Security helps us track our resources so that we don't get lost in the overwhelming volume of things and ensures we follow best practices. The solution gives us better visibility into our resources and enables faster resolution."
"SentinelOne Singularity Cloud Security is excellent, and I highly recommend it."
"The most valuable feature is the ability to share resources."
"Offers easy management with authentication and authorization features"
"The benefit of working with the solution is the fact that it's very straightforward...It is a perfectly stable product since the details are very accurate."
"The technical support is good."
"Scalability-wise, I rate the solution a nine out of ten."
"The most valuable feature of the solution is its monitoring feature."
"I like virtualization and all those tools that come with OpenShift. I also like Advanced Cluster Management and the built-in security."
"Segmentation is the most powerful feature."
"The tool's most valuable feature is scanning, reporting, and troubleshooting."
"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."
"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 helps us secure our applications from the build phase and identify the weaknesses from scratch."
"It is a scalable solution. Scalability-wise, it is a good solution."
"The strong security provided by the product in the container environment is its most valuable feature."
 

Cons

"There is room for improvement in the current active licensing model for PingSafe."
"For SentinelOne, improvements could be made in managing Internet dependency as cloud-based operations can pose challenges in environments with limited connectivity."
"The cloud-based operations might pose challenges in areas with limited or unavailable internet connectivity. Desktop features might be useful for smaller organizations with less complex security needs."
"Implementing single sign-on requires a pre-class account feature, which is currently not available."
"Once all components, including the cloud piece and container runtime piece, integrate further and incorporate an AI layer for better comprehension, it will greatly enhance the utility of Singularity Cloud Security."
"One of our use cases was setting up a firewall for our endpoints, specifically for our remote users... We were hoping to utilize SentinelOne's firewall capabilities, but there were limitations on how many URLs we could implement. Because of those limitations on the number of URLs, we weren't able to utilize that feature in the way we had hoped to."
"Crafting customized policies can be tricky."
"SentinelOne Singularity Cloud Security is an excellent CSPM tool, but its CWPP features need improvement, and there is scope for more application security posture management features."
"The initial setup is pretty complex. There's a learning curve, and its cost varies across different environments. It's difficult."
"The solution's price could be better."
"Red Hat is somewhat expensive."
"The support and specifications need to be up to date for the cluster technologies"
"The deprecation of APIs is a concern since the deprecation of APIs will cause issues for us every time we upgrade."
"I do see that some features associated with the IAST part are not included in the tool, making it an area where improvements are required."
"The documentation about Red Hat Advanced Cluster Security available online is very limited... So it's very limited to the documentation."
"The solution lacks features when compared to some of the competitors such as Prisma Cloud by Palo Alto Networks and has room for improvement."
"The support is tricky to reach, so we would like better-oriented technical support enabled."
"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."
"The solution’s pricing could be improved."
"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."
"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."
"Tenable.io Container Security should improve integration modules. It should also improve stability."
"The stability and setup phase of the product are areas with shortcomings where improvements are needed."
