Real-time assessments have improved remediation speed and reduced time spent on authentication issues

I do find that here and there with Contrast Security Assess there are user interface issues, particularly with how they work with libraries. The way that it works is people have access to library data for all applications, not just the applications that they should have access to. However, they are trying to fix that. The way the libraries are handled with Contrast Security Assess could use some work. I know that there is an additional service tier that allows for more in-depth library data. These are small things. Contrast support has been great in fixing any issues or getting back to us with questions. They seem to really be dedicated to the product.

Shifted security left and automated pull request checks to improve code hygiene and collaboration

Regarding GuardRails's AI capabilities, its governance and security controls are highly robust, requiring minimal, well-defined, read-only API access to codebases, and the central dashboard provides sufficient visibility into which repositories have high-risk patterns. Adding more advanced role-based access control inside the management panel would be perfect. The accuracy and reliability of GuardRails's output are impressive, with recommendations being highly practical and reliable. While any static analysis platform will yield occasional false positives on edge case logic, GuardRails filters out a lot of standard noise compared to legacy tools, making its output highly actionable for developers. The cloud-hosted SaaS deployment of GuardRails is used, which integrates directly with the managed version control system via secure OAuth webhooks. GuardRails is deployed on AWS as the cloud provider. GuardRails was purchased directly through a vendor rather than through the AWS Marketplace. GuardRails integrates with existing CI/CD tools and workflows by instantly connecting with version control systems like GitHub, GitLab, and Bitbucket via OAuth or app. GuardRails handles compliance requirements by being audit-ready, tracking, and automatically logging the security result of every commit and pull request, providing auditors with permanent, tamper-proof documentation of continuous code governance, industry framework mapping, proactive cloud safeguard, and data privacy gardening. Its sovereign and air-gapped deployment even offers an on-premise model, allowing highly regulated enterprises to keep all scanning data within their own network boundaries to meet strict data residence laws. GuardRails supports the team in onboarding new developers and training them on secure coding practices by having zero local setup. It hooks directly into repository layers, so engineers do not have to install any local CLI tools or IDE. Regarding open-source dependency scanning and vulnerability management, GuardRails provides deep dependency tracking that scans package managers and lock files to automatically uncover security flaws in both direct and deeply nested open-source libraries, including automated SBOM generation, real-time CVE spotting, upgrade guidance, license compliance checks, and monitoring of open-source licensing models in real time to prevent legally problematic copyleft compliance issues from compromising proprietary source. GuardRails supports collaboration between security and development teams by becoming the unified source of truth that bridges the organizational gap, providing a single platform where the security team sets high-level governance policy and development teams view daily actionable code. This removes the security cop friction and streamlines exception triage with shared responsibility models. My advice to others looking into using GuardRails is to start by activating it on the most critical repository first, working closely with engineering leads to establish a clear baseline for what counts as a breaking vulnerability, tuning the initial rule set to fit workflows, and then rolling out across the organization. I would rate GuardRails an eight out of ten.

Quotes from Members

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

Pros

"From a percentage perspective, somewhere around 90 percent of the time we used to spend has been given back to our team, because the false positive rate with Contrast is less than 5 percent."

"I am impressed with the product's identification of alerts and vulnerabilities."

"It is a stable solution...Contrast Security Assess is one of the first players in this market, so they have experience and customers, especially abroad. Overall, it's a good product."

"The accuracy of the solution in identifying vulnerabilities is better than any other product we've used, far and away. In our internal comparisons among different tools, Contrast consistently finds more impactful vulnerabilities, and also identifies vulnerabilities that are nearly guaranteed to be there, meaning that the chance of false positives is very low."

"We use the Contrast OSS feature that allows us to look at third-party, open-source software libraries, because it has a cool interface where you can look at all the different libraries. It has some really cool additional features where it gives us how many instances in which something has been used... It tells us it has been used 10 times out of 20 workloads, for example. Then we know for sure that OSS is being used."

"Contrast Security Assess has positively impacted my organization by providing more control over secure software development."

"The most valuable feature is the continuous monitoring aspect: the fact that we don't have to wait for scans to complete for the tool to identify vulnerabilities. They're automatically identified through developers' business-as-usual processes."

"In our most critical applications, we have a deep dive in the code evaluation, which was something we usually did with periodic vulnerability assessments, code reviews, etc. Now, we have real time access to it. It's something that has greatly enhanced our code's quality. We have actually embedded a KPI in regards to the improvement of our code shell. For example, Contrast provides a baseline where libraries and the usability of the code are evaluated, and they produce a score. We always aim to improve that score. On a quarterly basis, we have added this to our KPIs."

More Contrast Security Assess pros

"GuardRails has positively impacted the organization by fostering a collaborative DevSecOps culture, where developers actively fix security issues as they write code, leading to massive improvements in code hygiene and the DevOps team spending significantly less time reviewing code configuration vulnerabilities after deployment."

Cons

"I think there was activity underway to support the centralized configuration control. There are ways to do it, but I think they were productizing more of that."

"Contrast Security Assess covers a wide range of applications like .NET Framework, Java, PSP, Node.js, etc. But there are some like Ubuntu and the .NET Core which are not covered. They have it in their roadmap to have these agents. If they have that, we will have complete coverage."

"I would like to see them come up with more scanning rules."

"The solution needs to improve flexibility...The scalability of the product is a problem in the solution, especially from a commercial perspective."

"The solution should provide more details in the section where it shows that third-party libraries have CVEs or some vulnerabilities."

"Regarding Contrast Security Assess's AI capabilities, I think they are missing a huge opportunity because they could lead the way in automatic testing and AI security testing, but currently, they do not offer this functionality, which is a shame."

"Their level of support and troubleshooting for the product is limited because of how they handle troubleshooting. It's done through a log file that's very cumbersome to work with."

"The product's retesting part needs improvement. The tool also needs improvement in the suggestions provided for fixing vulnerabilities. It relies more on documentation rather than on quick fixes."

More Contrast Security Assess cons

"To improve GuardRails, more granular customization options for exclusions would be beneficial, especially when dealing with legacy codebases where certain non-critical alerts should be ignored without disabling an entire scanning engine."

Pricing and Cost Advice

"The solution is expensive."

"The good news is that the agent itself comes in two different forms: the unlicensed form and the licensed form. Unlicensed gives use of that software composition analysis for free. Thereafter, if you apply a license to that same agent, that's when the instrumentation takes hold. So one of my suggestions is to do what we're doing: Deploy the agent to as many applications as possible, with just the SCA feature turned on with no license applied, and then you can be more choosy and pick which teams will get the license applied."

"The product's pricing is low. I would rate it a two out of ten."

"For what it offers, it's a very reasonable cost. The way that it is priced is extremely straightforward. It works on the number of applications that you use, and you license a server. It is something that is extremely fair, because it doesn't take into consideration the number of requests, etc. It is only priced based on the number of onboarded applications. It suits our model as well, because we have huge traffic. Our number of applications is not that large, so the pricing works great for us."

"I like the per-application licensing model... We just license the app and we look at different vulnerabilities on that app and we remediate within the app. It's simpler."

"It's a tiered licensing model. The more you buy, as you cross certain quantity thresholds, the pricing changes. If you have a smaller environment, your licensing costs are going to be different than a larger environment... The licensing is primarily per application. An application can be as many agents as you need. If you've got 10 development servers and 20 production servers and 50 QA servers, all of those agents can be reporting as a single application that utilizes one license."

"You only get one license for an application. Ours are very big, monolithic applications with millions of lines of code. We were able to apply one license to one monolithic application, which is great. We are happy with the licensing. Pricing-wise, they are industry-standard, which is fine."
