Featured Reviews

Andrew W - PeerSpot reviewer
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.

An operational system, similar to Linux where you can run your applications inside containers
With CoreOS, you can run your applications inside containers. For example, if you have an application that needs to run on Linux, you can create and install a container. However, it's important to note that you don't install CoreOS inside a container; CoreOS is the host operating system that manages containers. When you mentioned using Nacula as part of your CI/CD pipeline, it means your application is deployed and managed automatically through the CI/CD process. Containers are used to deploy your application within this pipeline, but CoreOS does not run inside these containers. Instead, CoreOS is the base operating system that supports and manages these containers.

Enables seamless local Kubernetes development and quick deployment to the cloud
Rancher Desktop provides support for Kubernetes setup on local machines. It allows us to run Kubernetes as per our requirement, and the desktop application offers a good UI. We use Rancher Desktop for local development, testing APIs locally, and it helps to seamlessly publish to the cloud. This makes it a valuable tool for developers.

Quotes from Members

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

Pros

"The dashboard gives me an overview of all the things happening in the product, making it one of the tool's best features."
"SentinelOne Singularity Cloud Security has improved our security posture."
"The most valuable feature of SentinelOne Singularity Cloud Security is its advanced AI and machine learning capabilities, which allow it to identify and respond to threats in real time."
"SentinelOne Singularity Cloud Security 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."
"The cloud misconfiguration is the most valuable feature."
"The solution helped free other staff to work on other projects or other tasks. We basically just had to do a bunch of upfront configuring. With it, we do not have to spend as much time in the console."
"SentinelOne Singularity Cloud Security offers security solutions for both Kubernetes and CI/CD pipelines."
"It's helped free up staff time so that they can work on other projects."
"With CoreOS, you can run your applications inside containers. For example, if you have an application that needs to run on Linux, you can create and install a container. However, it's important to note that you don't install CoreOS inside a container; CoreOS is the host operating system that manages containers."
"CoreOS Clair's best feature is detection accuracy."
"Rancher Desktop provides support for Kubernetes setup on local machines."
"The most valuable features of SUSE Rancher include the user interface and the display features."

Cons

"Their search feature could be better."
"SentinelOne Singularity Cloud Security is an excellent CSPM tool, but the CWPP features need to improve, and there is a scope for more application security posture management features. There aren't many ASPM solutions on the market, and existing ones are costly. I would like to see SentinelOne Singularity Cloud Security develop into a single pane of glass for ASPM, CSPM, and CWPP. Another feature I'd like to see is runtime protection."
"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."
"SentinelOne Singularity Cloud Security can improve by eliminating 100 percent of the false positives."
"SentinelOne Singularity Cloud Security is an excellent CSSPM tool, but the CSC CWPP features need improvement."
"I request that SentinelOne investigate this false positive, as SentinelOne has a higher false positive rate than other XDR solutions."
"The areas with room for improvement include the cost, which is higher compared to other security platforms. The dashboard can also be laggy."
"There's room for improvement in the graphic explorer."
"An area for improvement is that CoreOS Clair doesn't provide information about the location of vulnerabilities it detects."
"It can be improved in its support response. They usually take up to seven days to resolve the issue."
"Additional features for a paid solution should be included, such as more detailed insights, better graphics, and an improved user interface."
"Some initial setup and configuration were required by the admin side for enabling security policies, which were not supported initially."
"Some initial setup and configuration were required by the admin side for enabling security policies, which were not supported initially."
 

Pricing and Cost Advice

"For pricing, it currently seems to be in line with market rates."
"PingSafe falls somewhere in the middle price range, neither particularly cheap nor expensive."
"The tool is cost-effective."
"It was reasonable pricing for me."
"As a partner, we receive a discount on the licenses."
"SentinelOne is relatively cheap. If ten is the most expensive, I would rate it a seven."
"Singularity Cloud Security by SentinelOne is cost-efficient."
"I wasn't sure what to expect from the pricing, but I was pleasantly surprised to find that it was a little less than I thought."
"CoreOS Clair is open-source and free of charge."
