Checkmarx One excels in scalability, integration, and automation, efficiently managing various organizational sizes though licensing can be restrictive.
Sentiment score
7.7
Mend.io effectively scales for large projects, integrates with workflows, and supports CI/CD, enhancing security and collaboration.
Sentiment score
7.1
SonarQube Server efficiently scales for various user volumes and project sizes, though infrastructure demands may rise in physical setups.
I find SonarQube Server (formerly SonarQube) very scalable because we're able to create a new repository and integrate all the tools on that project and it just works.
I would rate the scalability of SonarQube Server as a 10 because we can configure the server to scan multiple projects based on the number of lines.
 

Stability Issues

Sentiment score
7.2
Checkmarx One is reliable with some performance issues during large scans; user ratings vary from six to ten.
Sentiment score
7.7
Mend.io offers reliable performance, seamless integration, quick issue resolution, and supports diverse needs with minimal downtime and intuitive interface.
Sentiment score
7.7
SonarQube Server is highly reliable, stable with minor issues often related to plugins or environments, and rarely crashes.
I would rate the stability of this solution a nine on a scale of 1 to 10 where one is low stability and 10 is high.
AI integration in code security tools like Mend.io is still in its early stages and relatively immature.
I think SonarQube Server (formerly SonarQube) is stable, and we did not face any problems unless there was a power outage or if the LAN cable was plugged out.
 

Room For Improvement

Checkmarx One needs enhanced false positive reduction, language support, CD integration, pricing, UI, reporting, and automation improvements.
Mend.io requires UI and reporting enhancements, wider language support, improved scanning, automation, and cost-effective pricing for better user experience.
SonarQube Server needs better issue detection, usability, language support, integration, customizable features, and AI-driven dynamic testing enhancements.
It could suggest how the code base is written and automatically populate the source code with three different solution options to choose from.
The actual challenge is how easy it is to integrate it in the early phase of the software development life cycle.
The organization decided to consolidate tools and chose Snyk since it provides multiple functionalities in one solution.
Currently, it should also be able to analyze the code and generate and fix the code for specific developers or features that the developers are tracking.
If I fix some vulnerabilities today, they reappear in the next scan, and there will be completely different issues that need to be fixed.
 

Setup Cost

Checkmarx One offers high quality and performance, though its pricing varies and is often seen as expensive yet competitive.
Mend.io offers a competitive yearly pricing model based on developer count, appealing for enterprises but pricey for startups.
SonarQube Server provides cost-effective solutions for code quality, with competitive pricing and enhanced features for various project sizes.
The cost of Mend.io is competitive, being quite low compared to others.
They always offer around a two-year contract, but we always take a one-year contract because it's expensive.
I would rate the pricing for SonarQube Server (formerly SonarQube) as an 8, where 1 is very cheap and 10 is very expensive, because Coverity is very expensive, and while SonarQube is not cheap, it is still less expensive than Coverity.
The freemium version of SonarQube Server offers excellent value, especially compared to the high costs of Snyk.
 

Valuable Features

Checkmarx One provides comprehensive vulnerability analysis with intuitive features, efficient reporting, CI/CD integration, and extensive language support.
Mend.io streamlines vulnerability management with automation, integration, and comprehensive tools for tracking and securing open-source dependencies.
SonarQube Server enhances code quality with language support, CI/CD integration, insightful dashboards, and an intuitive interface.
My experience with the initial setup of Checkmarx One is straightforward; it is not complex compared to other tools that I have tried.
We find it 100% accurate in detecting vulnerabilities.
It handles Application Security, performing SCA SAST and container scanning.
We use SonarQube Server's centralized management and visualization of code quality metrics on the dashboard because that's the executive dashboard that we send to the executives to show where we are in terms of quality, security, and where the company can improve.
The most valuable features of SonarQube Server (formerly SonarQube) for us include having control of the rules, enabling and disabling them.
Some of the static code analysis capabilities are the most beneficial.

Syed Hasan - PeerSpot reviewer
Partner experiences excellent technical support and seamless initial setup
In my opinion, if we are able to extract or show the report, and because everything is going towards agent tech and GenAI, it would be beneficial if it could get integrated with our code base and do the fix automatically. It could suggest how the code base is written and automatically populate the source code with three different solution options to choose from. This would be really helpful.

Enables smooth management of vulnerabilities and promotes a shift towards a culture of security
We have witnessed Mend.io for its high stability, consistently living up to our expectations in terms of performance and reliability. Our developers have reported very few issues and almost minimal to zero downtime, which is a critical factor for our organization to rely on Mend SCA to secure our applications. We didn't experience any major issues in the stability of the product. This level of dependability is crucial for our hundreds of development teams that need to maintain continuous integration and deployment processes without interruptions. We realize the solution's architecture is designed to support a wide range of use cases, making it suitable for organizations of varying sizes and complexities. As a SaaS (Software as a Service) offering, Mend.io eliminates the need for physical server management, which further contributes to its stability. Users can access the platform without worrying about hardware failures or maintenance issues that can affect on-premises solutions. Moreover, Mend.io's integration capabilities with existing workflows—including IDEs, repositories, and CI/CD pipelines—enhance its stability by providing a seamless user experience. This integration allows teams to incorporate security scanning into their development processes without significant disruptions, which is often a challenge with less stable solutions. Feedback from our developers and architects highlights the tool's effectiveness in reducing open-source software vulnerabilities while maintaining a streamlined development lifecycle. Our organization have experienced improved code quality and faster incident response times as a result of using Mend.io. The platform's intuitive dashboard and management views are also praised by our developers for their usability, contributing to a positive user experience. In short, Mend.io stands out as a dependable and reliable solution in the realm of software composition analysis. Its high stability, combined with robust integration capabilities and user-friendly features, makes it an excellent choice for organizations seeking to enhance their security posture while minimizing operational disruptions.
Sthembiso Zondi - PeerSpot reviewer
Consistent improvements in code quality and security with effective integration and reliable technical support
The features of SonarQube Server (formerly SonarQube) that I find most useful are the suggestions received from reviewing the code. When they review the code, they provide suggestions on how to fix it, and we find those very useful from a development perspective. We use SonarQube Server's (formerly SonarQube) centralized management and visualization of code quality metrics on the dashboard because that's the executive dashboard that we send to the executives to show where we are in terms of quality, security, and where the company can improve. We use that for organizational improvement purposes. The ability to tailor metrics tracking in SonarQube Server (formerly SonarQube) has been beneficial to my team. There are team-specific dashboards which are related to specific repositories they utilize, and we have that aggregative dashboard that shows the whole organization's performance. We can drill down per specific repository, which makes it easier for the team to improve specific things.
