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.

Runtime threat detection has improved and security teams prioritize real Kubernetes risks

The best feature Sysdig Secure offers is threat detection. The threat detection feature on Sysdig Secure stands out compared to other solutions I have seen or used because Sysdig sees the actual behavior inside the container or kernel and correlates it with Kubernetes infrastructure, which makes detection both earlier and more precise in a cloud-native environment. Sysdig Secure has positively impacted our organization by improving visibility into our Kubernetes environment and focusing on real risk, which has reduced alert noise, improved threat detection at runtime, and made vulnerability management more efficient by prioritizing issues that actually affect running workloads.

Quotes from Members

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

Pros

"CoreOS Clair's best feature is detection accuracy."

"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."

"From a container-based standpoint, it offers excellent scalability to its users...I would tell those planning to use the solution that, from a container standpoint, it's excellent."

"Sysdig Secure has positively impacted our organization by improving visibility into our Kubernetes environment and focusing on real risk, which has reduced alert noise, improved threat detection at runtime, and made vulnerability management more efficient by prioritizing issues that actually affect running workloads."

"I have not seen any stability issues so far."

"We appreciate this feature, especially when combined with CD monitoring. The implementation of requested features has been remarkable, such as scanning for compliance in CRM processes for the US government. We heavily rely on this feature to assess compliance with federal requirements."

"I see Sysdig as the most comprehensive solution in comparison to its competitors."

"The most valuable feature is the level of support that we get. Our solutions or customer success representative is very valuable. I see them as an extension of our security team."

"Sysdig Secure has many strong foundational features like compliance and benchmark, security, network access management, and vulnerability management."

"The tool has the capability to conduct scans initially. It can perform scans on your virtual machines, physical machines, containers, and container images. A standout feature is its ability to scan offline container images stored in your container registry. Additionally, it can scan runtime images in your cluster or on your host machine. This allows for the detection of vulnerabilities in running containers, including loaded libraries. Notably, the tool can identify which library vulnerabilities are already present in your system. An added advantage is its capacity to take action beyond threat detection. It has the ability to block access and respond to encountered threats."

More Sysdig Secure pros

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."

"I give it an eight because of the bugs, specifically the fix version bug where sometimes there is no fix version shown, and I wish Sysdig Secure would create a customizable UI that orders features by importance to enhance user experience."

"Banks and financial institutions cannot use Sysdig Secure because it doesn't sell SaaS-hosted versions for under two hundred working nodes."

"Perhaps, it could support more custom implementations, as our company utilizes custom implementations rather than standard ones. Configuring it requires a deep understanding and adjustment to our specific needs, which took some time. Other than that, I'm unsure about potential improvements. We were considering the possibility of compartmentalizing their tools. Currently, in Sysdig Secure, they bundle multiple features, and we are unable to use them individually. For instance, if we only need compliance scanning, we have to deploy the entire secure package. This is because of the way their agent functions, but I can't delve into more details."

"Reporting can definitely be better. Live dashboards should be configurable for a longer period of time rather than 30 days. Being able to go back in time to compare six months ago to today would be valuable."

"Sysdig Secure works well for us, but there are a few areas for improvement, such as the alerting and notification system being more flexible for complex workflows, and some dashboard and reporting features could be more customizable to match specific team needs."

"The solution needs to improve overall from a CSPM standpoint since they can't compete with Wiz or Orca."

"The dashboard could be more simple and show the more important issues that are detected first. We'd like to be able to set it up so more important issues show up more prominently in the dashboard."

"Sysdig Secure needs to scale more for complete cloud-native coverage."

More Sysdig Secure cons

Pricing and Cost Advice

"CoreOS Clair is open-source and free of charge."

"In comparison to other cloud solutions, it's reasonably priced. However, when compared to in-house built open-source projects, it might be considered somewhat costly. The cost depends on whether someone sees the support provided by Sysdig as an advantage or if it's deemed unnecessary. Personally, I find the support to be excellent and consider it a good value."

"Sysdig is competitive. The quality matches the pricing. Obviously, everyone wants things to be cheaper, but if you're realistic, you acknowledge that quality service comes with a price. Sysdig is the gold standard for Kubernetes, and I wouldn't choose anything else. We live in Kubernetes. Everything is containerized, so that means a lot to us, and we're willing to make an investment."

"The solution's pricing depends on the agents...In short, the price depends on the environment of its user."

"It is quite costly compared to other tools."

"I am always going to say that it could be a little bit cheaper. I do feel that it is a little bit on the expensive side."

Overview

Clair is an open source project for the static analysis of vulnerabilities in appc and docker containers.

Vulnerability data is continuously imported from a known set of sources and correlated with the indexed contents of container images in order to produce lists of vulnerabilities that threaten a container. When vulnerability data changes upstream, the previous state and new state of the vulnerability along with the images they affect can be sent via webhook to a configured endpoint. All major components can be customized programmatically at compile-time without forking the project.

Red Hat

In the cloud, every second counts. Attacks move at warp speed, and security teams must protect the business without slowing it down. Sysdig stops cloud attacks in real time, instantly detecting changes in risk with runtime insights, a unique AI architecture, and open source Falco. Sysdig delivers live visibility by correlating signals across cloud workloads, identities, and services to uncover hidden attack paths. By knowing what is running, teams can prioritize the vulnerabilities, misconfigurations, permissions, and threats that matter most. From prevention to defense, Sysdig helps enterprises move faster and focus on what matters: innovation.
