Continuous in-app security has transformed our development workflow and has reduced manual checks
Contrast Security Assess changes how the team thinks about security. Instead of us waiting for a security audit at the end of any sprint, vulnerabilities surface as developers are writing and testing code. That shift is significant because fixing a bug in development costs more than fixing it later. It captures everything right there and remediates it because it catches vulnerability and remediates immediately while the application is running. It improves our collaboration between development and security teams, as developers get clear actionable findings immediately. We get continuous visibility into our application risk posture. Ultimately, it helps us to shift fast and save money, which is usually a trade-off, but Contrast Security Assess makes both possible. The feature that stands out most to me in Contrast Security Assess is the ability to capture vulnerability while the application is running. Another standout feature is the real-time detection that finds vulnerabilities as code runs. It has fewer false positives and works continuously in the application; you install it and it is there. It captures issues during development quickly and is easily integrated with a CI/CD pipeline, especially if you are using GitLab or GitHub. The real-time detection feature of Contrast Security Assess helps us very well compared to traditional SAST tools. Traditional tools scan from the outside and guess where problems might be. Contrast Security Assess works from the inside because it is embedded into the application. The agent lives inside the running application, allowing it to see exactly what is happening in real-time. This means we are getting accurate alerts instead of a long list of potential issues that require manual investigation. When it comes to the CI/CD pipeline, Contrast Security Assess really shines for our daily work, as it plugs directly into tools like Jenkins, GitHub, or Azure DevOps. When a developer commits code and triggers a build, Contrast Security Assess is already testing it in the background. If there is any vulnerability, the pipeline automatically flags or stops the application before bad code reaches production. This means security becomes everyone's responsibility, not just the security team's, and it gives us real-time, accurate security that fits into how our team already works.

Codenomicon Defensics should be more advanced for the testing sector. It should be somewhat easy and flexible to install. What I see in the documentation isn't that. Even if something doesn't malfunction, sometimes it is hard to install and execute. The product needs video documentation. This would help a lot more.

Quotes from Members

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

Pros

"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."
"Security feedback comes to developers instantly with Contrast Security Assess, reducing costs by about 50%."
"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."
"Overall, the product is strong and improving, support is responsive and effective, and supported integrations work for many customers."
"I am impressed with the product's identification of alerts and vulnerabilities."
"Assess has an excellent API interface to pull APIs."
"One of the key takeaways is that in order to have a secure application, you cannot rely on just the pentest, vulnerability assessments, and the periodicity of the reviews; you need the real-time feedback on that, and Contrast Assess offers that."
"When we access the application, it continuously monitors and detects vulnerabilities."
"Whatever the test suit they give, it is intelligent; it will understand the protocol and it will generate the test cases based on the protocol: protocol, message sequence, protocol, message structure, and because of that, we can eliminate a lot of unwanted test cases so we can execute the tests and complete them very quickly."
"Simple and straightforward GUI."
"The product is related to US usage with TLS contact fees, i.e. how more data center connections will help lower networking costs."
"ROI was 100%. Since there are no product suites available that provide the level of testing available with Codenomicon, the development, quality and security assurance departments know that the investment was correct."
"The stability of this product is great; we tested it under multiple constraints and even on cloud services it is absolutely stable."
"We have found multiple issues in our embedded system network protocols, related to buffer overflow. We have reduced some of these issues."
 

Cons

"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."
"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."
"The solution needs to improve flexibility...The scalability of the product is a problem in the solution, especially from a commercial perspective."
"I would like to see them come up with more scanning rules."
"Regarding the solution's OSS feature, the one drawback that we do have is that it does not have client-side support. We'll be missing identification of libraries like jQuery or JavaScript, and such, that are client-side."
"Contrast's ability to support upgrades on the actual agents that get deployed is limited. Our environment is pretty much entirely Java. There are no updates associated with that. You have to actually download a new version of the .jar file and push that out to your servers where your app is hosted. That can be quite cumbersome from a change-management perspective."
"The solution should provide more details in the section where it shows that third-party libraries have CVEs or some vulnerabilities."
"The setup of the solution is different for each application. That's the one thing that has been a challenge for us. The deployment itself is simple, but it's tough to automate because each application is different, so each installation process for Contrast is different."
"You can't implement proprietary ciphering algorithms, nor can you modify protocol models if you need to test customized public protocols."
"It does not support the complete protocol stack. There are some IoT protocols that are not supported and new protocols that are not supported."
"Sometimes, when we are testing embedded devices, when we trigger the test cases, the target will crash immediately. It is very difficult for us to identify the root cause of the crash because they do not provide sophisticated tools on the target side. They cover only the client-side application... They do not have diagnostic tools for the target side. Rather, they have them but they are very minimal and not very helpful."
"Codenomicon Defensics should be more advanced for the testing sector. It should be somewhat easy and flexible to install."
"It requires understanding the Defensics protocol."
 

Pricing and Cost Advice

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