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.

Web audits have identified vulnerabilities and now provide clear visibility into compliance gaps
We have experience with Tenable.io Web Application Scanning, and we use it as well; we have approximately ten licenses for web application scanning. We use it to find vulnerabilities, but Tenable.io Web Application Scanning does not include remediation; we remediate with other products. We use the…

Quotes from Members

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

Pros

"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."
"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."
"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."
"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."
"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."
"Assess has brought our development time down because it helps create code the first time."
"By far, the thing that was able to provide value was the immediate response while testing ahead of release, in real-time."
"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."
"The most valuable features of Tenable.io Web Application Scanning are the integration into specific use cases and scanning. All of the features of the solution are useful."
"We use the tool for our websites. We have a vulnerable subdomain. The tool helps to scan it for vulnerabilities."
"The most effective feature of the product is the ability to scan the entire environment."
"All the features are valuable to us as they offer cutting-edge scanning methods and address the latest issues with a contemporary approach. Tenable.io Web Application Scanning is highly stable. I rate it a nine out ten. Since the solution works on the Cloud, it's highly scalable. I rate the scalability a nine out of ten. The setup of the solution is straightforward. The Return on Investment is substantial. I recommend the solution to all."
"It is fully automated."
"The solution's instant reports feature is the most effective for detecting threats."
"The most valuable feature is the reporting, which provides a good level of detail with respect to vulnerabilities."
"I would recommend Tenable.io Web Application Scanning to others."
 

Cons

"Contrast Security Assess could improve in the reporting and the dashboard experience."
"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."
"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."
"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 needs to improve flexibility...The scalability of the product is a problem in the solution, especially from a commercial perspective."
"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."
"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 report customization needs to be better."
"The cloud and the on-premises versions have their own controllers, and there is no way to centrally manage controllers."
"Sometimes it lags with different cloud environments."
"The technical support should be improved. Currently, some attacks are detected while others are not."
"The dashboard could be more user-friendly."
"It would be great if there were a dashboard that is more user-friendly."
"Tenable.io Web Application Scanning conducts a general scan, which wastes time. The scan needs to be specific."
"The solution's dashboards could be improved and made more user-friendly."
 

Pricing and Cost Advice

"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."
"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."
"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."
"The solution is expensive."
"It follows the same licensing scheme as Tenable.io and Tenable. sc."
"The application is extremely affordable. There are no additional costs involved with licensing. We switched to Tenable.io Web Application Scanning from other solutions due to pricing."
"Tenable.io Web Application Scanning is expensive for small businesses."
"I rate the product's pricing a four out of ten."
"The price of the solution is reasonable compared to the competitors. The license cost is based on the number of users and the annual usage."
"For Tenable.io Web Application Scanning, it comes to around 6,50,000 Indian rupees, plus taxes."
"The pricing is okay."
