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.

Pros

"Assess has an excellent API interface to pull APIs."
"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."
"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."
"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."
"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."
"I am impressed with the product's identification of alerts and vulnerabilities."
"By far, the thing that was able to provide value was the immediate response while testing ahead of release, in real-time."
"OWASP is quite matured in identifying the vulnerabilities."
"The stability of the solution is very good."
"The most valuable feature is scanning the URL to drill down all the different sites."
"Automatic updates and pull request analysis."
"Simple and easy to learn and master."
"The ZAP scan and code crawler are valuable features."
"​It has improved my organization with faster security tests.​"
"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."
 

Cons

"The solution should provide more details in the section where it shows that third-party libraries have CVEs or some vulnerabilities."
"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 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 out-of-the-box reporting could be improved. We need to write our own APIs to make the reporting more robust."
"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."
"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."
"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."
"It needs more robust reporting tools."
"For scalability, I would rate OWASP Zap between four to five out of ten."
"They stopped their support for a short period. They've recently started to come back again. In the early days, support was much better."
"It would be a great improvement if they could include a marketplace to add extra features to the tool."
"The documentation needs to be improved because I had to learn everything from watching YouTube videos."
"The work that it does in the limited scope is good, but the scope is very limited in terms of the scanning features. The number of things it tests or finds is limited. They need to make it a more of a mainstream tool that people can use, and they can even think about having it on a proprietary basis. They need to increase the coverage of the scan and the results that it finds. That has always been Zap's limitation. Zap is a very good tool for a beginner, but once you start moving up the ladder where you want further details and you want your scan to show more in-depth results, Zap falls short because its coverage falls short. It does not have the capacity to do more."
"The forced browse has been incorporated into the program and it is resource-intensive."
"The product should allow users to customize the report based on their needs."
 

Pricing and Cost Advice

"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."
"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 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."
"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."
"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."
"This app is completely free and open source. So there is no question about any pricing."
"We have used the freeware version. I believe Zap only has freeware."
"This is an open-source solution and can be used free of charge."
"It is open source, and we can scan freely."
"The tool is open-source."
"As Zap is free and open-source, with tons of features similar to those of commercial solutions, I would definitely recommend trying it out."
"It is highly recommended as it is an open source tool."
"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."
