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

"I would rate SentinelOne Singularity Cloud Security a ten out of ten."
"We like SentinelOne Singularity Cloud Security's vulnerability assessment and management features, and its vulnerability databases."
"They're responsive to feature requests. If I suggest a feature for Prisma, I will need to wait until the next release on their roadmap. Cloud Native Security will add it right away."
"The key strength of Singularity Cloud Security lies in its ability to pinpoint vulnerabilities in our cloud accounts and identify suspicious activity that warrants further investigation."
"SentinelOne Singularity Cloud Security offers several valuable features, most notably the rapid vulnerability notifications that provide timely alerts regarding our infrastructure."
"It is very straightforward. It is not complicated. For the information that it provides, it does a pretty good job."
"The visibility SentinelOne Singularity Cloud Security provides into the Cloud environment is a valuable feature."
"The compliance monitoring feature of SentinelOne Singularity Cloud Security gives us a report with a compliance score to ensure we meet certain regulatory standards."
"The most beneficial security feature of the product revolves around the areas of vulnerability and configuration."
"It is easy to install and manage."
"I like virtualization and all those tools that come with OpenShift. I also like Advanced Cluster Management and the built-in security."
"I am impressed with the tool's visibility."
"The technical support is good."
"The most valuable feature of the solution is its monitoring feature."
"Scalability-wise, I rate the solution a nine out of ten."
"One of the most valuable features I found was the ability of this solution to map the network and show you the communication between your containers and your different nodes."
"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."
"The strong security provided by the product in the container environment is its most valuable feature."
"The solution shows you the exploitable vulnerabilities and helps you prioritize."
"The tool's most valuable feature is scanning, reporting, and troubleshooting."
"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."
 

Cons

"While SentinelOne offers robust security features, its higher cost may present a challenge for budget-conscious organizations."
"We use SentinelOne Singularity Cloud Security and also SentinelOne. If SentinelOne Singularity Cloud Security integrated some of the endpoint security features of SentinelOne, it would be the perfect one-stop solution for everything. We wouldn't need to switch between the products. At my organization, I am responsible for endpoint security and vulnerability management. Integrating both functions into one application would be ideal because I could see all the alerts, heat maps, and reports in one console."
"To enhance the notification system's efficiency, resolved issues should be promptly removed from the portal."
"SentinelOne Singularity Cloud Security has limited legacy system support and may not fully support older operating systems or legacy environments."
"The Automation tab is an add-on that doesn’t work properly. They provide a list of scripts that don’t work and I have asked support to assist but they won’t help. When running on various endpoints the script doesn’t work and if it does, it’s only a couple. There are a lot of useful scripts that would be beneficial to run forensics, event logs, and process lists running on the endpoint."
"There is a bit of a learning curve for new users."
"I request that SentinelOne investigate this false positive, as SentinelOne has a higher false positive rate than other XDR solutions."
"While the future roadmap presented by SentinelOne appears promising, I hope the envisioned advancements are realistically achievable and that the gap between current offerings and long-term goals is not too significant."
"The deprecation of APIs is a concern since the deprecation of APIs will cause issues for us every time we upgrade."
"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 solution's price could be better."
"They're trying to convert it to the platform as a source. They are moving in the direction of Cloud Foundry so it can be easier for a developer to deploy it."
"The support and specifications need to be up to date for the cluster technologies"
"The solution's visibility and vulnerability prevention should be improved."
"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 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."
"The support is tricky to reach, so we would like better-oriented technical support enabled."
"The initial setup is highly complex."
"The stability and setup phase of the product are areas with shortcomings where improvements are needed."
"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."
"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."
 

Pricing and Cost Advice

"The features included in PingSafe justify its price point."
"Its pricing was a little less than other providers."
