Enable secure development workflows while identifying opportunities for faster scans and improved AI guidance

Checkmarx One is a very strong platform, but there are several areas where it can improve to support modern DevSecOps workflows even better. For example, better real-time developer guidance is needed. The IDE plugin should offer richer AI-powered auto-fixes similar to SNYK Code or GitHub Copilot Security, as current guidance is good but not deeply contextual for large-scale enterprise codebases. This matters because it reduces developer friction and accelerates shift-left adoption. More transparency control over the correlation engines is another need. The correlation engine is powerful but not fully transparent. Users want to understand why vulnerabilities were correlated or de-prioritized, which helps AppSec teams trust the prioritization logic. Faster SAST scan and more language coverage is needed since SAST scan can still be slow for very large mono-repos and there is limited deep support for new language frameworks like Rust and Go, along with advanced coverage for serverless-specific frameworks. This matters because large organizations want sub-minute scans in CI/CD as cloud-native ecosystems evolve fast. A strong API security module is another area for enhancement. API security scanning could be improved with active testing, API discovery, full Swagger, OpenAPI, drift detection, and schema-based fuzzing. This is important as API attacks are one of the biggest AppSec risks in 2025. Checkmarx One is strong, but I see a few areas for improvement including faster SAST scanning for large mono-repos, deeper language framework support, more transparent correlation logic, and stronger API security that includes discovery and runtime context. The IDE plugin could offer more AI-assisted fixes, and the SBOM lifecycle tracking can evolve further. Enhancing integration with SIEM and SOAR would also make enterprise adoption smoother, and these improvements would help developers and AppSec teams move faster with more accuracy.

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.

Quotes from Members

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

Pros

"It shows in-depth code of where actual vulnerabilities are."

"The main thing we find valuable about Checkmarx is the ease of use. It's easy to initiate scans and triage defects."

"Overall, I use Checkmarx One as a strategic control point to improve developer velocity while strengthening application security across the full software lifecycle."

"The features and technologies are very good. The flexibility and the roadmap have also been very good. They're at the forefront of delivering the additional capabilities that are required with cloud delivery, etc. Their ability to deliver what customers require and when they require is very important."

"The administration in Checkmarx is very good."

"The solution is always updating to continuously add items that create a level of safety from vulnerabilities. It's one of the key features they provide that's an excellent selling point. They're always ahead of the game when it comes to finding any vulnerabilities within the database."

"The solution improved the efficiency of our code security reviews. It helps tremendously because it finds hundreds of potential problems sometimes."

"Helps us check vulnerabilities in our SAP Fiori application."

More Checkmarx One 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."

Cons

"We can run only one project at a time."

"They should make it more container-friendly and optimized for the CI pipeline. They should make it a little less heavy. Right now, it requires a SQL database, and the way the tool works is that it has an engine and then it has an analysis database in which it stores the information. So, it is pretty heavy from that perspective because you have to have a full SQL Server. They're working on something called Checkmarx Light, which is a slim-down version. They haven't released it yet, but that's what we need. There should be something a little more slimmed down that can just run the analysis and output the results in a format that's readable as opposed to having a full, really big, and thick deployment with a full database server."

"Checkmarx is not good because it has too many false positive issues."

"The statistics module has a function that allows you to show some statistics, but I think it's limited. Maybe it needs more information."

"The resolutions should also be provided. For example, if the user faces any problem regarding an installation due to the internal security policies of their company, there should be a resolution offered."

"Creating and editing custom rules in Checkmarx is difficult because the license for the editor comes at an additional cost, and there is a steep learning curve."

"The validation process needs to be sped up."

"They could work to improve the user interface. Right now, it really is lacking."

More Checkmarx One 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."

Pricing and Cost Advice

"This solution is expensive. The customized package allows you to buy additional users at any time."

"The price of Checkmarx could be reduced to match their competitors, it is expensive."

"Be cautious of the one-year subscription date. Once it expires, your price will go up."

"For around 250 users or committers, the cost is approximately $500,000."

"I would rate the solution’s pricing an eight out of ten. The tool’s pricing is higher than others and it is for the license alone."

"Checkmarx is comparatively costlier than other products, which is why some of the customers feel reluctant to go for it, though performance-wise, Checkmarx can compete with other products."

"Most of my customers opted for a perpetual license. They prefer to pay the highest amount up front for the perpetual license and then pay for additional support annually."

"The pricing is competitive and provides a lower TCO (total cost of ownership) for achieving application security."

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

Checkmarx

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.
