Featured Reviews

Felipe Giffu - PeerSpot reviewer
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.
Utsav Sharma - PeerSpot reviewer
Maintain operational efficiency by detecting misconfigurations and vulnerabilities
The vulnerability scanning feature is excellent as it supports various container capabilities like Docker and Sharma. It also offers repository scanning in the source code domain, allowing pre-push code scans. The misconfiguration detection works well for CloudFormation, Docker files, and Terraform. Its compliance support, like NIST, ensures that configurations align with standards. Trivy helps me significantly detect misconfigurations missed by the ops engineers or in Terraform by the naked eye. It ensures that my deployments are free of misconfigurations and vulnerabilities.

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 most valuable feature of Trivy is its easy integration with the CI/CD pipeline."
"Trivy is very reliable and always has an up-to-date database to scan images and identify vulnerabilities."
"Trivy is easy to integrate with CI/CD and can be installed on desktops to scan images."
"It is open-source."
"Trivy's ability to scan files, images, GitHub repositories, Infrastructure as Code like Terraform, and Kubernetes is valuable."
"Trivy's open source nature and wide functionality are incredibly valuable."
"It's customizable, allowing me to add any rules and format HTML templates as I wish."
"The most valuable feature of Trivy is its easy integration with the CI/CD pipeline."
 

Cons

"It can be improved in its support response. They usually take up to seven days to resolve the issue."
"An area for improvement is that CoreOS Clair doesn't provide information about the location of vulnerabilities it detects."
"The reporting could be a little better. When integrating Trivy with CI, the interpretation of the reports could be improved."
"Trivy generates many false positives, flagging non-existent vulnerabilities. Improvements could include better contextual analysis or granular filtering."
"The reporting could be a little better."
"For malware detection, I need to use two tools: Trivy as my anomaly scanner and ClamAV. I am integrating these two tools into the CI pipeline. If both malware and anomaly detection could be managed by one tool, I would not need to depend on two tools. That would be my suggestion."
"In our CI/CD pipelines, Trivy lacks built-in functionality for report analysis."
"The only problem is that Trivy does not support reporting features such as generating reports in CSV, which is useful for auditing and reporting."
"For malware detection, I need to use two tools: Trivy as my anomaly scanner and ClamAV. I am integrating these two tools into the CI pipeline. If both malware and anomaly detection could be managed by one tool, I would not need to depend on two tools."
"Currently, the container image scanning is static. A dynamic scanning capability during runtime would be a significant advantage."
