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.

Shifted security left and automated pull request checks to improve code hygiene and collaboration

Regarding GuardRails's AI capabilities, its governance and security controls are highly robust, requiring minimal, well-defined, read-only API access to codebases, and the central dashboard provides sufficient visibility into which repositories have high-risk patterns. Adding more advanced role-based access control inside the management panel would be perfect. The accuracy and reliability of GuardRails's output are impressive, with recommendations being highly practical and reliable. While any static analysis platform will yield occasional false positives on edge case logic, GuardRails filters out a lot of standard noise compared to legacy tools, making its output highly actionable for developers. The cloud-hosted SaaS deployment of GuardRails is used, which integrates directly with the managed version control system via secure OAuth webhooks. GuardRails is deployed on AWS as the cloud provider. GuardRails was purchased directly through a vendor rather than through the AWS Marketplace. GuardRails integrates with existing CI/CD tools and workflows by instantly connecting with version control systems like GitHub, GitLab, and Bitbucket via OAuth or app. GuardRails handles compliance requirements by being audit-ready, tracking, and automatically logging the security result of every commit and pull request, providing auditors with permanent, tamper-proof documentation of continuous code governance, industry framework mapping, proactive cloud safeguard, and data privacy gardening. Its sovereign and air-gapped deployment even offers an on-premise model, allowing highly regulated enterprises to keep all scanning data within their own network boundaries to meet strict data residence laws. GuardRails supports the team in onboarding new developers and training them on secure coding practices by having zero local setup. It hooks directly into repository layers, so engineers do not have to install any local CLI tools or IDE. Regarding open-source dependency scanning and vulnerability management, GuardRails provides deep dependency tracking that scans package managers and lock files to automatically uncover security flaws in both direct and deeply nested open-source libraries, including automated SBOM generation, real-time CVE spotting, upgrade guidance, license compliance checks, and monitoring of open-source licensing models in real time to prevent legally problematic copyleft compliance issues from compromising proprietary source. GuardRails supports collaboration between security and development teams by becoming the unified source of truth that bridges the organizational gap, providing a single platform where the security team sets high-level governance policy and development teams view daily actionable code. This removes the security cop friction and streamlines exception triage with shared responsibility models. My advice to others looking into using GuardRails is to start by activating it on the most critical repository first, working closely with engineering leads to establish a clear baseline for what counts as a breaking vulnerability, tuning the initial rule set to fit workflows, and then rolling out across the organization. I would rate GuardRails an eight out of ten.

Quotes from Members

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

Pros

"I like that you don't have to compile the code in order to execute static code analysis. So, it's very handy."

"The biggest advantage we have seen is that we're able to develop and deliver secure solutions in a faster time."

"The most valuable features are the easy to understand interface, and it 's very user-friendly."

"We have been using this product extensively for a lot of applications to identify as well as employ proper remediation which makes the application secure including information issues which might get neglected with a manual code review process."

"The license is fairly costly but worth the investment."

"The scalability of the solution is good."

"The most valuable feature is the simple user interface."

"The setup is very easy. There is a lot of information in the documents which makes the install not difficult at all."

More Checkmarx One pros

"GuardRails has positively impacted the organization by fostering a collaborative DevSecOps culture, where developers actively fix security issues as they write code, leading to massive improvements in code hygiene and the DevOps team spending significantly less time reviewing code configuration vulnerabilities after deployment."

"We have achieved roughly a forty percent reduction in production-level vulnerabilities and eliminated accidental credential leaks into our Git history entirely."

Cons

"Checkmarx could improve the REST APIs by including automation."

"Checkmarx isn't accredited by the US government for DOD networks, so we've been forced to remove it from the network."

"The interactive application security testing, or IAST, the interactive part where you're looking at an application that lives in a runtime environment on a server or virtual machine, needs improvement."

"The purchase of this solution was a mistake. I would advise others to deploy the solution and to test all of the functionality before buying and do not trust the marketing from Checkmarx."

"We are trying to find out if there is a way to identify the run-time null values. I am analyzing different tools to check if there is any tool that supports run-time null value identification, but I don't think any of the tools in the market currently supports this feature. It would be helpful if Checkmarx can identify and throw an exception for a null value at the run time. It would make things a lot easier if there is a way for Checkmarx to identify nullable fields or hard-coded values in the code. The accessibility for customized Checkmarx rules is currently limited and should be improved. In addition, it would be great if Checkmarx can do static code and dynamic code validation. It does a lot of security-related scanning, and it should also do static code and dynamic code validation. Currently, for security-related validation, we are using Checkmarx, and for static code and dynamic code validation, we are using some other tools. We are spending money on different tools. We can pay a little extra money and use Checkmarx for everything."

"The product's reporting feature could be better. The feature works well for developers, but reports generated to be shared with external parties are poor, it lacks the details one gets when viewing the results directly from the Checkmarx One platform."

"I would like to see the DAST solution in the future."

"They can support the remaining languages that are currently not supported."

More Checkmarx One cons

"To improve GuardRails, more granular customization options for exclusions would be beneficial, especially when dealing with legacy codebases where certain non-critical alerts should be ignored without disabling an entire scanning engine."

Pricing and Cost Advice

"Before implementing the product I would evaluate if it is really necessary to scan so many different languages and frameworks. If not, I think there must be a cheaper solution for scanning Java-only applications (which are 90% of our applications)."

"It's relatively expensive."

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

"We got a special offer for a 30% reduction for three years, after our first year. I think for a real source-code scanning tool, you have to add a lot of money for Open Source Analysis, and AppSec Coach (160 Euro per user per year)."

"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."

"We're using a commercial version of Checkmarx, and we paid for the solution for one year. The price is high and could be reduced."

"Checkmarx is not a cheap scanning tool, but none of the security tools are cheap. Checkmarx is a powerful scanning tool, and it’s essential to have one of these products."

"The solution's price is high and you pay based on the number of users."
