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.

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

"The time it saves us is on the order of one US-based FTE, a security person at an average pay level, and at a bare minimum Contrast helps us like that resource; it's like having a CISSP guy, in the US, on our payroll."
"Overall, the product is strong and improving, support is responsive and effective, and supported integrations work for many customers."
"Contrast was a very complete solution; it met all of our technical requirements and it was really the only IAST product that felt like a real product."
"I am impressed with the product's identification of alerts and vulnerabilities."
"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."
"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."
"It has helped us to improve the overall security posture of the company, we are able to address the findings before they have been reported by a third-party, and it has also helped us to gain our customers' trust."
"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."
"Stability-wise, I rate the solution a nine out of ten. I think it's stable enough. I don't see any crashes within the application, so its stability is high."
"​It has improved my organization with faster security tests.​"
"It can be used effectively for internal auditing."
"The community edition updates services regularly. They add new vulnerabilities into the scanning list."
"Technical support is excellent."
"OWASP is definitely in the top three as a tool that we would probably recommend to our team, as a frequent users' tool, however, I don't believe we have any kind of a formal relationship with the company."
"It's great that we can use it with Portswigger Burp."
"The solution is very easy to use, the initial setup is straightforward, it is free due to the fact that it is open-source, the stability is very good, and the product has a strong community surrounding it to help with issues and troubleshooting."
 

Cons

"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."
"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."
"I think Contrast can also integrate with some AI tools and provide chat features if possible, so in case we have any more questions, we can chat with that chatbot and get remediations, which I believe would be a better enhancement to Contrast."
"Contrast Security Assess could improve in the reporting and the dashboard experience."
"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."
"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 solution should provide more details in the section where it shows that third-party libraries have CVEs or some vulnerabilities."
"The product should allow users to customize the report based on their needs."
"There are too many false positives."
"It would be nice to have a solid SQL injection engine built into Zap."
"Sometimes, we get some false positives."
"It's possibly just a limitation of the product itself but sometimes it won't scan a particular website so you have to manually go in and make some configuration changes."
"The disadvantage of Zap is that we're unable to customize reports as it only has a single standard format."
"It needs more robust reporting tools that can be in an editable form."
"There's very little documentation that comes with OWASP Zap."
 

Pricing and Cost Advice

"The solution is expensive."
"The product's pricing is low. I would rate it a two out of ten."
"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."
"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."
"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 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 solution’s pricing is high."
"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 solution is open source and free."
"This app is completely free and open source. So there is no question about any pricing."
"It is open source, and we can scan freely."
"OWASP ZAP is a free tool provided by OWASP’s engineers and experts. There is an option to donate."
"The tool is open source."
"OWASP Zap is free to use."
