Featured Reviews

ToddMcAlister - PeerSpot reviewer
It has an excellent API interface to pull APIs.
Assess has brought our development time down because it helps create code the first time. Instead of going through the Jenkins process to build an application, they can see right off the bat that if there are errors in the code and fix them before it even goes to build.
Amit Beniwal - PeerSpot reviewer
Simplifies vulnerability discovery and has high quality support
There are areas for improvement with OWASP Zap, particularly in the alignment of vulnerabilities concerning CVSS scores. Sometimes, a vulnerability initially categorized as high severity may be reduced to medium or low over time after security patches are applied. This alignment with the present severity score and CVSS score could be improved.

Quotes from Members

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

Pros

"This has changed the way that developers are looking at usage of third-party libraries, upfront. It's changing our model of development and our culture of development to ensure that there is more thought being put into the usage of third-party libraries."
"By far, the thing that was able to provide value was the immediate response while testing ahead of release, in real-time."
"No other tool does the runtime scanning like Contrast does. Other static analysis tools do static scanning, but Contrast is runtime analysis, when the routes are exercised. That's when the scan happens. This is a tool that has a very unique capability compared to other tools. That's what I like most about Contrast, that it's runtime."
"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 solution is very accurate in identifying vulnerabilities. In cases where we are performing application assessment using Contrast Assess, and also using legacy application security testing tools, Contrast successfully identifies the same vulnerabilities that the other tools have identified but it also identifies significantly more. In addition, it has visibility into application components that other testing methodologies are unaware of."
"Assess has an excellent API interface to pull APIs."
"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."
"When we access the application, it continuously monitors and detects vulnerabilities."
"The reporting is quite intuitive, which gives you a clear indication of what kind of vulnerability you have that you can drill down on to gather more information."
"The solution has tightened our security."
"The application scanning feature is the most valuable feature."
"The community edition updates services regularly. They add new vulnerabilities into the scanning list."
"The stability of the solution is very good."
"Automatic updates and pull request analysis."
"The solution is scalable."
"Simple and easy to learn and master."
 

Cons

"I would like to see them come up with more scanning rules."
"The out-of-the-box reporting could be improved. We need to write our own APIs to make the reporting more robust."
"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."
"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."
"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."
"To instrument an agent, it has to be running on a type of application technology that the agent recognizes and understands. It's excellent when it works. If we're using an application that is using an unsupported technology, then we can't instrument it at all. We do use PHP and Contrast presently doesn't support that, although it's on their roadmap. My primary hurdle is that it doesn't support all of the technologies that we use."
"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."
"OWASP should work on reducing false positives by using AI and ML algorithms."
"It would be ideal if I could try some pre-built deployment scenarios so that I don't have to worry about whether the configuration sector team is doing it right or wrong. That would be very helpful."
"The reporting feature could be more descriptive."
"Sometimes, we get some false positives."
"There are areas for improvement with OWASP Zap, particularly in the alignment of vulnerabilities concerning CVSS scores."
"Reporting format has no output, is cluttered and very long."
"OWASP Zap could benefit from a noise cancellation feature like that of Burp Suite Professional, where AI helps reduce certain non-critical findings."
"ZAP's integration with cloud-based CICD pipelines could be better. The scan should run through the entire pipeline."
 

Pricing and Cost Advice

"The solution is expensive."
"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."
"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."
"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."
"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."
"The product's pricing is low. I would rate it a two out of ten."
"This app is completely free and open source. So there is no question about any pricing."
"The tool is open-source."
"OWASP Zap is free to use."
"It's free and open, currently under the Apache 2 license. If ZAP does what you need it to do, selling a free solution is a very easy."
"As Zap is free and open-source, with tons of features similar to those of commercial solutions, I would definitely recommend trying it out."
"This is an open-source solution and can be used free of charge."
"The solution’s pricing is high."
"It is highly recommended as it is an open source tool."
