ROI

Sentiment score
5.6
Checkmarx One enhances security by automating vulnerability detection, reducing costs, and improving development efficiency through CI/CD integration.
Sentiment score
4.8
Skybox Security Suite offers high ROI for large networks by automating firewall management, saving time and reducing breach costs.
Overall, between the fast scanning, automation, automatic reporting, and easy detection, it has reduced manual effort enough that we did not need an extra reviewer, even as our codebase or team size grew.
Senior GenAI Engineer at a tech vendor with 10,001+ employees
Based on my interactions with the clients, I can tell that there is a return on investment because if something is not profitable and it's not helping to save costs or vulnerabilities, clients wouldn't come back to renew their license year after year.

Room For Improvement

Checkmarx One needs enhancements in accuracy, speed, integration, UI, support, pricing, and features for enterprise usability.
Skybox Security Suite requires improvements in UI, web access, reporting, integration, pricing, support, cloud connectivity, and data processing.
Integration into the IDE being used would be beneficial so that code does not need to be uploaded to the website and an IDE-friendly report could be generated.

It could suggest how the code base is written and automatically populate the source code with three different solution options to choose from.
Specialist Leader at Deloitte
If you can improve the speed optimization, it takes around 30 to 40 minutes for checking a build. If you can make it within five minutes or 10 minutes, that would be great.
Senior Software Engineer at a tech vendor with 10,001+ employees
Reporting could have been improved, and feature requests often were not implemented.
Security Engineer at a financial services firm with 10,001+ employees
Only the licensing part of Skybox had an edge. We were not renewing the licenses of Skybox every year, but in the case of other tools, we would have to renew if we wanted to use those tools.
Security Architect at a tech vendor with 5,001-10,000 employees
It would be better if something more attractive or similar useful information found in AlgoSec was available.
Software Engineer at LTI - Larsen & Toubro Infotech
 

Setup Cost

Checkmarx One is often costly but provides quality and security, with costs varying by team size and selected modules.
Skybox Security Suite pricing has mixed reviews, seen as cost-effective by some, but expensive due to varied licensing models.
For a small team under 50 developers, normal expenses come under 30 to 60K.
Senior Solution Architect | L3+ Systems & Cloud Engineer | SRE Specialist at Canada Cloud Solution
Due to the number of years I've implemented Checkmarx One, there are rebates and discounts from the OEM which makes it a lot more profitable.
Chief Technology Officer at 3CS Aquarah Limited
The pricing should be reasonable, matching what we are paying for.
Senior GenAI Engineer at a tech vendor with 10,001+ employees
From a commercial perspective, AlgoSec is more expensive compared to Skybox Security Suite.

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.

Firewall policy management has improved access control but still needs simpler setup and upgrades
The features that I appreciated the most in Skybox Security Suite were not comparable with Tufin, as Tufin was far ahead in terms of the technology and the user interface. The effectiveness of the vulnerability management in Skybox Security Suite is an area I have not used that much. The firewall management feature has streamlined rule configuration and compliance in Skybox Security Suite and has evolved over time, but Tufin is far better. In terms of comparison between both tools, only the licensing part of Skybox had an edge. We were not renewing the licenses of Skybox every year, but in the case of other tools, we would have to renew if we wanted to use those tools. The disadvantages and weaknesses of Skybox Security Suite include the interface, complexity with setup, and upgrading. There are some smaller issues as well that would take more time to discuss, but there are ways around them. We use this tool to implement a new policy on the firewall by going to Skybox, creating a flow there, and then using an approval mechanism in place. There are two different levels of approvals which we have to go through, and once both approvers approve the request, we are ready to implement it. A specific challenge is that if we have to create a new object group and place ten different objects in that and use that object group in two different rules, we have to create the object group in the first rule and add the ten new objects. Then if we have to create another rule, we do not get an option to recall or reuse that same group which we created in the previous rule. We have to create a new object group again and then add the objects into it again. If we had created an object group once, we should have gotten an option to recall that or call that object group in the new rule, and that should have made the process easier.
