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.

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…

Pros

"Assess has brought our development time down because it helps create code the first time."
"Overall, the product is strong and improving, support is responsive and effective, and supported integrations work for many customers."
"Assess has an excellent API interface to pull APIs."
"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 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."
"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."
"I am impressed with the product's identification of alerts and vulnerabilities."
"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 product provides comprehensive details and reports to help us understand everything and handle any patches in order to keep our system safe."
"The most valuable feature is the reporting, which provides a good level of detail with respect to vulnerabilities."
"Now that the license is centralized, it's a significant feature to manipulate assets based on their functions."
"I would recommend Tenable.io Web Application Scanning to others."
"We can get detailed information about vulnerabilities."
"Tenable.io Web Application Scanning is very easy to use, provides very reliable results, and is easily managed by someone who lacks prior knowledge, information, or experience."
"Tenable.io Web Application Scanning is very easy to use."
"The most effective feature of the product is the ability to scan the entire environment."
 

Cons

"I would like to see them come up with more scanning rules."
"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."
"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."
"Personalization of the board and how to make it appealing to an organization is something that could be done on their end. The reports could be adaptable to the customer's preferences."
"Regarding the solution's OSS feature, the one drawback that we do have is that it does not have client-side support."
"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 out-of-the-box reporting could be improved. We need to write our own APIs to make the reporting more robust."
"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 would like for them to add intervening proxy, whereby you can alter the get/put requests."
"Tenable.io Web Application Scanning could improve by offering faster fuzzing."
"The platform's technical support services could be better."
"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 report customization needs to be better."
"I would like for them to add proxy filtering, where you can transfer and alter the package. It is fully automated. Other web application testers programs are actually proxy software, and the proxy software gives you the flexibility of modifying the outgoing package, which will actually help you in exploiting any vulnerability in detail."
"The dashboard could be more user-friendly."
"It isn't easy to manage vulnerabilities in Tenable."
 

Pricing and Cost Advice

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