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.

Improves organizational security with features like scanning, reporting, and troubleshooting
Tenable.io Container Security has improved our security.  The tool's most valuable feature is scanning, reporting, and troubleshooting.  Tenable.io Container Security should improve integration modules. It should also improve stability.  I have been working with the product for two years.  I…

Quotes from Members

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

Pros

"The most beneficial security feature of the product revolves around the areas of vulnerability and configuration."
"Segmentation is the most powerful feature."
"I am impressed with the tool's visibility."
"The most valuable feature of the solution is its monitoring feature."
"Offers easy management with authentication and authorization features"
"I like virtualization and all those tools that come with OpenShift. I also like Advanced Cluster Management and the built-in security."
"The most valuable feature is the ability to share resources."
"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."
"Nessus scanner is very effective for internal penetration testing."
"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."
"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."
"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."
"It helps us secure our applications from the build phase and identify the weaknesses from scratch."
"The strong security provided by the product in the container environment is its most valuable feature."
 

Cons

"The documentation about Red Hat Advanced Cluster Security available online is very limited... So it's very limited to the documentation."
"Red Hat is somewhat expensive."
"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 solution's visibility and vulnerability prevention should be improved."
"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 testing process could be improved."
"The support and specifications need to be up to date for the cluster technologies"
"The tool's command line and configuration are hard for us to understand and make deployment complex. It should also include zero trust, access control features and database connectivity."
"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 support is tricky to reach, so we would like better-oriented technical support enabled."
"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."
"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 stability and setup phase of the product are areas with shortcomings where improvements are needed."
"The initial setup is highly complex."
"Tenable.io Container Security should improve integration modules. It should also improve stability."
 

Pricing and Cost Advice

"It's a costly solution"
"We purchase a yearly basis license for the solution."
"Red Hat offers two pricing options for their solution: a separate price, and a bundled price under the OpenShift Platform Plus."
"The price of Red Hat Advanced Cluster Security for Kubernetes is better than Palo Alto Prisma."
"The pricing model is moderate, meaning it is not very expensive."
"The product does not operate on a pay-per-license model."
"I rate the product’s pricing a six 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."
"I rate the tool's pricing a three out of ten."
