We're gathering vulnerability data from multiple environments in real time, fundamentally changing how we identify issues in applications
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 also provides the option of helping developers incorporate security elements while they're writing code. It depends on whether individual developers decide to utilize the information that's provided to them from the solution, but it definitely gives them visibility into more environments. It gives them an opportunity to remediate vulnerabilities well before production deployments.

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

"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."
"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."
"Assess has an excellent API interface to pull APIs."
"When we access the application, it continuously monitors and detects vulnerabilities."
"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."
"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."
"Tenable provides the end analysis results covering all the published vulnerabilities and information on the market."
"Tenable.io Web Application Scanning is very easy to use."
"The most valuable feature is the reporting, which provides a good level of detail with respect to vulnerabilities."
"The solution's instant reports feature is the most effective for detecting threats."
"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."
"Now that the license is centralized, it's a significant feature to manipulate assets based on their functions."
"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."
 

Cons

"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."
"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."
"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."
"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."
"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."
"The solution needs to improve flexibility...The scalability of the product is a problem in the solution, especially from a commercial perspective."
"The solution should provide more details in the section where it shows that third-party libraries have CVEs or some vulnerabilities."
"Tenable.io Web Application Scanning is not very user-friendly and you need a lot of information to get proper reports. The tool's support is not very responsive."
"The cloud and the on-premises versions have their own controllers, and there is no way to centrally manage controllers."
"They have a general dashboard for web application scanning, but the dashboards and reporting can be improved. They probably have some features in their roadmap."
"Tenable.io Web Application Scanning could improve by offering faster fuzzing."
"It isn't easy to manage vulnerabilities in Tenable."
"The solution's dashboards could be improved and made more user-friendly."
"The reporting has a very limited customization capability."
"We have encountered some problems with the technical support from Tenable; I would rate it a five out of ten. It is not efficacious, especially the first-level support."
 

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."
"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 is expensive."
"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."
"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 product's pricing is low. I would rate it a two out of ten."
"It follows the same licensing scheme as Tenable.io and Tenable. sc."
"Tenable.io Web Application Scanning is expensive for small businesses."
"For Tenable.io Web Application Scanning, it comes to around 6,50,000 Indian rupees, plus taxes."
"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."
"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."
"The pricing is okay."
"I rate the product's pricing a four out of ten."
