Featured Reviews

Ravi Khanchandani - PeerSpot reviewer
Founder Director at Techsa Services
Has improved identification of encryption and authentication issues across cloud and on-prem applications
During the learning curve of onboarding HCL AppScan, we learned that HCL has altered the portfolio and now offers HCL AppScan 360, which has a much better look and feel with an improved user interface. However, there is one feature called SCA, which stands for Software Composition Analysis, that could be improved. When I'm doing an application scan, HCL AppScan has the ability to generate information about what components are in use. For example, if I'm scanning a web application, it shows me the various components being used. It tells me whether I have Java libraries, .NET frameworks, or other log management libraries such as Log4j, and what versions of those specific components are present. I would like to see more detailed reports from the tool. Currently, you can find out the components belonging to a specific software, but if detailed reporting became available, you would be in a better position to identify vulnerabilities. For instance, I could identify that I had the Log4j vulnerability and know that I need to fix my application accordingly. If they add the features I'm describing, I would consider giving them a higher rating. However, I've only been experienced with the product for three months.

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

"SAST is the only feature that works using the on-prem version."
"You can easily find particular features and functions through the UI."
"It's generally a very user-friendly tool. Anyone can easily learn how to scan"
"It is an application for security assessment or scanning for static environments, and with all customers, it is performing well."
"The HCL AppScan turnaround time for Burp Suite or any new feature request is pretty good, and that is why we are sticking with the HCL."
"The solution offers services in a few specific development languages."
"Scalability, and it's a very powerful tool."
"It provides a better integration for our ecosystem."
"As Zap is free and open-source, with tons of features similar to those of commercial solutions, I would definitely recommend trying it out."
"Two features are valuable. The first one is that the scan gets completed really quickly, and the second one is that even though it searches in a limited scope, what it does in that limited scope is very good. When you use Zap for testing, you're only using it for specific aspects or you're only looking for certain things. It works very well in that limited scope."
"The solution is scalable."
"The reporting is quite intuitive, which gives you a clear indication of what kind of vulnerability you have that you can drill down on to gather more information."
"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."
"Technical support is excellent."
"The application scanning feature is the most valuable feature."
"One valuable feature of OWASP Zap is that it is simple to use."
 

Cons

"In future releases, I would like to see more aggressive reports. I would also like to see less false positives."
"AppScan needs to improve its handling of false positives."
"The performance could be better. Sometimes it doesn't work so well."
"Visibility is an issue for us. Our partners were not even aware that we had an integration with AppSense."
"There is not a central management for static and dynamic."
"It has crashed at times."
"This product lacks in many areas, and so we are looking at other options."
"I would like to see the roadmap for this product. We are still waiting to see it as we have only so many resources."
"Online documentation can be improved to utilize all features of ZAP and API methods to make use in automation."
"If there was an easier to understand exactly what has been checked and what has not been checked, it would make this solution better. We have to trust that it has checked all known vulnerabilities but it's a bit hard to see after the scanning."
"Without any support, we are in a black hole sometimes."
"I would recommend this product to people although I think it is very difficult to deploy and we also have issues with maintenance."
"The ability to search the internet for other use cases and to use the solution to make applications more secure should be addressed."
"OWASP Zap needs to extend to mobile application testing."
"There's very little documentation that comes with OWASP Zap."
"Lacks resources where users can internally access a learning module from the tool."
 

Pricing and Cost Advice

"The solution is moderately priced."
"The tool was expensive."
"The price is very expensive."
"I would rate the product's pricing a nine out of ten. The product's pricing is expensive compared to the features that they offer."
"With the features, that they offer, and the support, they offer, AppScan pricing is on a higher level."
"The price of HCL AppScan is okay, in my opinion. You just buy HCL AppScan and don't pay anything anymore, meaning it is just a one-time purchase."
"I rate the product's price a seven on a scale of one to ten, where one is low, and ten is high. HCL AppScan is an expensive tool."
"The solution is cheap."
"OWASP Zap is free to use."
"This solution is open source and free."
"This is an open-source solution and can be used free of charge."
"OWASP ZAP is a free tool provided by OWASP’s engineers and experts. There is an option to donate."
"It is highly recommended as it is an open source tool."
"It's free and open, currently under the Apache 2 license. If ZAP does what you need it to do, selling a free solution is a very easy."
"We have used the freeware version. I believe Zap only has freeware."
"This app is completely free and open source. So there is no question about any pricing."
