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.

Chief Information Officer at a construction company with 1,001-5,000 employees

Has unified our IT teams by providing clear visibility into network vulnerabilities and accelerated remediation with real-world attack testing

One of the things that we've shared with Horizon is just the reporting. They've made a lot of changes over time, but when examining computers, most average normal people don't look at a computer and identify it as 114.82.117.180. They identify it as 'the printer for accounting.' When many of the reports give the very detailed technical IP address or serial number, that's really not helpful for anyone other than the person, the hands-on person that's trying to remediate it. All the managers, all the leaders, having information in that format isn't helpful. Being able to have information about what those devices are would be very helpful. There's a technical reason they can't just have an easy button because some people have really complicated networks. When examining things for the average company, the average executive, that 114 number, there's only one of those. But if examining an AT&T or a Walmart, it isn't unique. They haven't solved that problem. But for the 90% of companies, being able to have just a human readable name for all devices on your network in all of the reports all of the time would be the most beneficial.

Quotes from Members

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

Pros

"The only thing I like is that Checkmarx does not need to compile."

"The product's most valuable feature is static code and supply chain effect analysis. It provides a lot of visibility."

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

"Less false positive errors as compared to any other solution."

"Checkmarx pinpoints the vulnerability in the code and also presents the flow of malicious input across the application."

"Checkmarx offers many valuable features, including Static Application Security Testing (SAST), Software Composition Analysis (SCA), Infrastructure as Code (IAC), Supply Chain Security, and API Security."

"The most valuable features of Checkmarx are the SCA module and the code-checking module. Additionally, the solutions are explanatory and helpful."

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

More Checkmarx One pros

"My favorite feature about The NodeZero Platform is that it's autonomous, and it truly delivers on that promise—it can be set and forgotten while it performs its tasks, and it does exactly what it claims to do."

"Penetration testing and scans are useful features."

"The NodeZero Platform is amazing; what I love most about it is that it's automated and comparable to the manual pen testing we did with a third-party company, but with the added benefit of unlimited retesting to validate fixes."

"The NodeZero Platform's real attack capabilities help in identifying vulnerabilities on our on-prem systems because it provides actual vulnerabilities by attacking our systems."

"Overall, I'd rate NodeZero at nine to 9.5 out of ten."

"The NodeZero Platform's real attack capabilities help identify vulnerabilities on my on-premise systems by adding an element of validation and offensive security testing on top of known vulnerabilities. The feature that allows security teams to fix and retest vulnerabilities instantly is very useful, even though it may not happen literally 'instantly.' It's a necessary tool for any organization to understand whether vulnerabilities are genuinely exploitable by attackers. With its near-real-time testing capabilities, it's an essential part of any security portfolio."

"I rate the stability of the NodeZero Platform a ten out of ten."

"Honestly, it's one of the most transformational technologies we've implemented in our company."

Cons

"When we first ran it on a big project, there wasn't enough memory on the computer. It originally ran with eight gigabytes, and now it runs with 32. The software stopped at some point, and while I don't think it said it ran out of memory, it just said "stopped" and something else. We had to go to the logs and send them to the integrator, and eventually, they found a memory issue in the logs and recommended increasing the memory. We doubled it once, and it didn't seem enough. We doubled it again, and it helped."

"One area for improvement in Checkmarx is pricing, as it's more expensive than other products."

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

"We would like to be able to run scans from our local system, rather than having to always connect to the product server, which is a longer process."

"Micro-services need to be included in the next release."

"This product requires you to create your own rulesets. You have to do a lot of customization."

"C, C++, VB and T-SQL are not supported by this product. Although, C and C++ were advertised as being supported."

"The Dynamic Application Security Testing (DAST) feature should be better."

More Checkmarx One cons

"The speed of the scans takes some time, but in my opinion, it is not surprising for what it is doing."

"Sometimes even their support doesn't know why we're seeing certain issues."

"I think The NodeZero Platform could improve by leveraging GPUs for password cracking, which would be pretty good."

"They've added a chatbot which isn't particularly useful, but when it can't answer questions, it forwards messages to human support."

"You need to be cautious about what it scans, as it could potentially cause issues."

"One of the areas where improvement is needed is in the visibility and reporting for large enterprises."

"The only issue we’ve encountered is that sometimes the scans take a long time to complete."

"I encountered challenges with patch management, as we struggled to test and implement patches due to time constraints. This led to our patch management process being ineffective."

Pricing and Cost Advice

"The solution is costly."

"We have a subscription license that is on a yearly basis, and it's a pretty competitive solution."

"We have purchased an annual license to use this solution. The price is reasonable."

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

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

"The license has a vague language around P1 issues and the associated support. Make sure to review these in order to align them with your organizational policies."

"If you want more, you have to pay more. You have to pay for additional modules or functionalities."

"It is a good product but a little overpriced."
