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 us to prioritize and effectively address critical security issues
Evidence-based reporting helps us to prioritize and solve critical security issues. The new visualization feature demonstrates how an attacker can enter the system, highlighting the potential path that can be exploited and outlining all the steps the attacker could take. With that visibility, we can ensure the perimeter is strong and attackers cannot enter, thus reducing the risk. It has helped us prioritize issues. The visibility into how an attack could happen is valuable. For example, it highlights the system vulnerability and outlines where an attack could propagate. The visualization helps me to prioritize remediation, and if I don't know where to start, I can check to see the score that enables me to prioritize issues. I am using infrastructure-as-code scanning, and it's one of the useful features. In pre-production, it identifies embedded secrets and misconfigurations, including issues with Kubernetes or some privileged containers. This feature allows us to pass the audit and secure IaC code so that it isn't easily exploitable by attackers. We can more proactively work to identify and resolve vulnerabilities by using the dashboard and the alerting system that SentinelOne provides. It helps us with audits and compliance. We can show the compliance in percentage. We can confidently say that our company or infrastructure is very secure. It has improved our security posture by 30% to 35%. It has reduced our false positives by 30%. It has helped teams collaborate better. The security team manages SentinelOne Singularity Cloud Security, and when it flags vulnerabilities, they are forwarded to DevOps for remediation. Previously, we needed to identify and report the issues, but there would be lapses in communication. Now, there is a centralized dashboard that anyone can look at and see the open issues and work on them.

Pros

"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."
"The mean time to detect has been reduced."
"I rate SentinelOne Singularity Cloud Security ten out of ten."
"The most valuable features of SentinelOne Singularity Cloud Security are cloud misconfiguration, Kubernetes, and IaC scanning."
"With SentinelOne Singularity Cloud Security, it's easy to onboard new accounts."
"The real-time detection and response capabilities overall are great."
"The visibility is the best part of the solution."
"The GUI is one of the best features. Audit reports and documentation for alerts are also valuable."
"Visibility is the most important aspect."
 

Cons

"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."
"The area of improvement is the cost, which is high compared to other traditional endpoint protections."
"Implementing single sign-on requires a pre-class account feature, which is currently not available."
"I export CSV. I cannot export graphs. Restricting it to the CSV format has its own disadvantages. These are all machine IP addresses and information. I cannot change it to the JSON format. The export functionality can be improved."
"here is a bit of a learning curve. However, you only need two to three days to identify options and get accustomed."
"The cloud-based operations might pose challenges in areas with limited or unavailable internet connectivity."
"We repeatedly get alerts on the tool dashboard that we've already solved on our end, but they still appear. That is somewhat irritating."
"It took us a while to configure the software to work well in this type of environment, as the support documents were not always clear."
"To enhance the notification system's efficiency, resolved issues should be promptly removed from the portal."
 

Pricing and Cost Advice

"CoreOS Clair is open-source and free of charge."
"I understand that SentinelOne is a market leader, but the bill we received was astronomical."
"The cost for PingSafe is average when compared to other CSPM tools."
"The price depends on the extension of the solution that you want to buy. If you want to buy just EDR, the price is less. XDR is a little bit more expensive. There are going to be different add-ons for Singularity."
"Singularity Cloud Workload Security's pricing is good."
"Singularity Cloud Security by SentinelOne is cost-efficient."
"The licensing is easy to understand and implement, with some flexibility to accommodate dynamic environments."
"Their pricing appears to be based simply on the number of accounts we have, which is common for cloud-based products."
"SentinelOne is relatively cheap. If ten is the most expensive, I would rate it a seven."
