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.

Quotes from Members

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

Pros

"The value you can get out of the speedy production may be worth the price tag."

"The identification of verification-related security vulnerabilities is really important and one of the key things. It also identifies vulnerabilities for any kind of third-party tool coming into the system or any third-party tools that you are using, which is very useful for avoiding random hacking."

"We were using HPE Security Fortify to scan code for security vulnerabilities, but it can scan only after a successful compile. If the code has dependencies or build errors, the scan fails. With Checkmarx, pre-compile scanning is seamless. This allows us to scan more code."

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

"Checkmarx One has positively impacted our organization as we tend to find vulnerabilities very early in the development cycle."

"Checkmarx One has positively impacted the organization by providing resolution strategies and indicating which vulnerabilities need to be fixed."

"The setup is fairly easy. We didn't struggle with the process at all."

"It has all the features we need."

More Checkmarx One pros

"Rapid7 AppSpider is good at managing different applications. It uses applets and generates reports to cover the PCA/GDPR compliance requirements."

"It is really accurate and the rate of false positives is very low."

"The entire solution is interactive and has a point-and-click user experience, which makes it easy to find items or drill down on information. You don't need specialized skills to use the product."

"It scans all the components developed within a web application."

"The most valuable feature of Rapid7 AppSpider is the vulnerability reporting data. Additionally, the data is reported in a convenient way rather than seeing them as a PDF. We are able to generate all the reports exactly what we want in a flexible way."

"The setup is usually straightforward."

"I like the ability the product has to detect vulnerabilities quickly, when it has been released in our environment, then displaying them to us."

"The initial deployment is very straightforward and simple. The product is stable if configured properly."

More Rapid7 AppSpider pros

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."

"I can't create a business case with multiple-factor authentication."

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

"We have received some feedback from our customers who are receiving a large number of false positives."

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

"The cost per user is high and should be reduced."

"I think the CxAudit tool has room for improvement. At the beginning you can choose a scan of a project, but in any event the project must be scanned again (wasting time)."

"We want to have a holistic view of the portfolio-level dashboard and not just an individual technical project level."

More Checkmarx One cons

"The tech support is responsive but issues remain unresolved."

"Implementing Rapid7 AppSpider requires scanning and self-identification mechanisms. You can add different types of authentication to each scan."

"AppSpider could improve in the area of integration. They need to add more integration opportunities."

"Integration could be better."

"The product needs to be able to scale for large companies, like ours. We have millions of IP addresses that need to be scanned, and the scalability is not great."

"The enterprise interface is too simple. It should be more customizable."

"AppSpider has some problems with the RAM needed while scanning."

"The solution is too slow. It could take a full day to scan. Competitors are much faster."

More Rapid7 AppSpider cons

Pricing and Cost Advice

"The number of users and coverage for languages will have an impact on the cost of the license."

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

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

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

"It is an expensive solution."

"The pricing was not very good. This is just a framework which shouldn’t cost so much."

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

"The solution is costly."

More Checkmarx One pricing and cost advice

"It is expensive if you want to buy the Enterprise version that is able to scan multiple applications at once."

"AppSpider is closed-source software and you need to acquire a license in order to use it."

"The licensing cost depends on the number of users."

"The price of Rapid7 AppSpider cost 9,000 annually but there is limited usage. Large companies are able to negotiate a better price or a better deal for the usage with the vendor."

"The price is pretty fair."
