Real-time assessments have improved remediation speed and reduced time spent on authentication issues

I do find that here and there with Contrast Security Assess there are user interface issues, particularly with how they work with libraries. The way that it works is people have access to library data for all applications, not just the applications that they should have access to. However, they are trying to fix that. The way the libraries are handled with Contrast Security Assess could use some work. I know that there is an additional service tier that allows for more in-depth library data. These are small things. Contrast support has been great in fixing any issues or getting back to us with questions. They seem to really be dedicated to the product.

Quotes from Members

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

Pros

"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."

"Assess has brought our development time down because it helps create code the first time."

"Contrast Security Assess has positively impacted my organization by providing a good way to find issues faster than regular static scanning, which after a while was unable to really find anything, giving us more visibility on the real code that is used in production along with the active DLLs that were loaded by our application in the backend, which helped us identify where the risk could be."

"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."

"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."

"Contrast Security Assess has positively impacted my organization by improving the security features of our application."

"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."

More Contrast Security Assess pros

"I would recommend Tenable.io Web Application Scanning to others."

"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."

"It collects the vulnerabilities on the hostnames and sends them to the Tenable.io cloud. Tenable has its own cloud where Tenable.io is running, but there are many connectors to other cloud solutions. Tenable can do vulnerability scanning for other cloud managers such as Azure, Amazon, and so on."

"Now that the license is centralized, it's a significant feature to manipulate assets based on their functions."

"Our customers adopt this solution because of the replication testing and the vulnerability assessment it can do. It is a multi-faceted product."

"Tenable provides the end analysis results covering all the published vulnerabilities and information on the market."

"The most valuable feature is the reporting, which provides a good level of detail with respect to vulnerabilities."

"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

"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 would rate Contrast Security Assess a seven out of ten because I think it's a good product, better than average, but I'm sure it has a lot of room for growth."

"The solution should provide more details in the section where it shows that third-party libraries have CVEs or some vulnerabilities."

"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."

"The solution needs to improve flexibility...The scalability of the product is a problem in the solution, especially from a commercial perspective."

"The product's retesting part needs improvement. The tool also needs improvement in the suggestions provided for fixing vulnerabilities. It relies more on documentation rather than on quick fixes."

"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."

"I would like to see them come up with more scanning rules."

More Contrast Security Assess cons

"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."

"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."

"Sometimes it lags with different cloud environments."

"Tenable.io Web Application Scanning conducts a general scan, which wastes time. The scan needs to be specific."

"Tenable.io Web Application Scanning could improve by offering faster fuzzing."

"I would like for them to add intervening proxy, whereby you can alter the get/put requests."

"The platform's technical support services could be better."

Pricing and Cost Advice

"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."

"The product's pricing is low. I would rate it a two out of ten."

"The solution is expensive."

"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."

"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 rate the product's pricing a four out of ten."

"Tenable.io Web Application Scanning is expensive for small businesses."

"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."

"For Tenable.io Web Application Scanning, it comes to around 6,50,000 Indian rupees, plus taxes."

"The pricing is okay."

"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."
