Checkmarx One and Tenable Nessus compete in the cybersecurity domain, focusing on vulnerability detection and code security. Checkmarx One appears to have the upper hand with comprehensive code scanning capabilities and robust security investments.
Features: Checkmarx One provides comprehensive code scanning without the need for compiling, reducing false positives and supporting numerous languages and integrations. It offers robust code analysis and source code tracking, alongside incremental scanning. Tenable Nessus is noted for its extensive database and predictive features, offering broad vulnerability detection with strong network coverage.
Room for Improvement: Checkmarx One faces challenges with its high pricing and complex licensing. It requires improvements in language support and reporting capabilities, as well as reduced hardware dependencies. Tenable Nessus needs enhanced cloud integration and more intuitive reporting. The interface customization and pricing flexibility are also areas needing attention.
Ease of Deployment and Customer Service: Checkmarx One supports various deployment options, including private, public, and hybrid clouds, although some delays in technical support are reported. Tenable Nessus offers diversified deployment settings with well-regarded, swift, and knowledgeable technical support.
Pricing and ROI: Checkmarx One is often considered expensive but justified for security investments, offering flexibility across environments with a complex license model. Users note a positive ROI in terms of secure delivery speeds. Tenable Nessus is praised for competitive pricing, offering different licensing options based on IP addresses, and is perceived as cost-effective, especially for comprehensive support services.
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.
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.
If you raise a support case with Checkmarx, it is handled smoothly.
The customer support team is amazing and they provide on-phone call, email support, and on-website support.
I have relied on Checkmarx One customer support hundreds of times for several things, and Checkmarx One support is very proactive and very responsive.
We received support within one to three hours.
Whenever any issue arises, we contact the support, and they are always there for us.
The technical support is good yet could improve in terms of response time.
Approximately four billion lines of code are being scanned monthly.
Since it is cloud-based, the infrastructure and PaaS, IaaS, and SaaS are taken care of by the cloud marketplace.
Checkmarx One's scalability has changed my organization because the strong collaboration between the development and security team helps us to do things much faster.
Whether managing 50 servers today or 500 tomorrow, performance or capacity are not hindered.
Tenable Nessus is definitely scalable, especially for license formats designed for scalability.
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.
Checkmarx One is often down when the cloud provider experiences issues.
We have not encountered any issues with missing network items or errors in API and webhook interactions.
The stability of Tenable Nessus is extraordinary.
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.
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.
This is Tenable's property. They want to sell Tenable Security Center, and they closed all the API capability for Tenable Nessus Professional.
An AI feature that helps them discover options without requiring them to deep dive into all features or guides them through advisory functions would be beneficial.
The documentation is not well-organized, which can be confusing when searching for solutions or specific information related to Tenable Nessus Professional.
For a small team under 50 developers, normal expenses come under 30 to 60K.
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.
The pricing should be reasonable, matching what we are paying for.
The pricing for Tenable Nessus has increased significantly, tripling over the last few years.
Tenable Nessus's pricing is adequate if it is fully utilized.
When we compare it to other solutions, it is more difficult for us to negotiate the price for Tenable Nessus than to negotiate the price with Rapid7.
Since replacing the previous tool, SAST and SCA scans are conducted in a couple of minutes instead of hours or days.
The best features Checkmarx One offers, over the past years, include broad language and technical support that Checkmarx provides, covering most languages.
Checkmarx One has positively impacted our organization as we tend to find vulnerabilities very early in the development cycle.
I mostly use the configuration audit feature for the audit configuration as a scan policy, and I will use it for credential audit, which helps me scan credentials access such as local administrator or root access, performing a deeper and more accurate check of local configuration settings and file systems, making it a highly recommended feature.
The scanning and reporting features are the most valuable aspects of Tenable Nessus.
The most valuable features of Tenable Nessus include its ease of access and quick usability.
