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

"AppScan's most valuable features include its ability to identify vulnerabilities accurately, provide detailed remediation steps, and the newly introduced AI-powered features that enhance its functionality further."
"The most valuable feature of HCL AppScan is scanning QR codes."
"The solution is easy to use."
"It is a stable solution...It is a scalable solution...The initial setup or installation of HCL AppScan is easy."
"The product has valuable features for static and dynamic testing."
"Scalability, and it's a very powerful tool."
"This solution saves us time due to the low number of false positives detected."
"I prefer Appscan, as it much more user friendly, and it detects cross-site scripting and SQL injection issues much better than other tools in the market."
"Fuzzer and Java APIs help a lot with our custom needs."
"It's great that we can use it with Portswigger Burp."
"The solution is very easy to use, the initial setup is straightforward, it is free due to the fact that it is open-source, the stability is very good, and the product has a strong community surrounding it to help with issues and troubleshooting."
"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."
"The vulnerabilities that it finds, because the primary goal is to secure applications and websites."
"It scans while you navigate, then you can save the requests performed and work with them later."
"The most valuable feature is the spidering because, being a security person, it is very important for me to know each and every section of that application, so we cannot afford to miss any single web page or any single link on a particular website."
"Stability-wise, I rate the solution a nine out of ten. I think it's stable enough. I don't see any crashes within the application, so its stability is high."
 

Cons

"Currently, we are satisfied with AppScan but I am sure there are better alternatives available because this is a very old product."
"I think it's a little bit complex, and that's quite a common issue with most of the IBM products."
"There are so many lines of code with so many different categories that I am likely to get lost. ​"
"The solution needs to improve in some areas. The tool needs to add more languages. It also needs to improve its speed."
"The solution could improve by having a mobile version."
"The depth was low, but the part that the user could miss was also diagnosed."
"Unfortunately, there is a big discussion if it is very expensive to use it or not, and there are competitors."
"The solution often has a high number of false positives. It's an aspect they really need to improve upon."
"There's very little documentation that comes with OWASP Zap."
"Right now, I can't give it off to a team and expect them to give me a report that I'm happy with."
"I would like to see a version of “repeater” within OWASP ZAP, a tool capable of sending from one to 1000 of the same requests, but with preselected modified fields, changing from a predetermined word ​list, or manually created."
"We have had stability issues a few times."
"We're currently moving away from OWASP to PortSwigger Burp Suite Professional; it's more user-friendly with a better interface."
"Reporting format has no output, is cluttered and very long."
"When comparing OWASP Zap and Burp Suite, the main difference besides pricing is that OWASP Zap has limitations with reporting levels and UI, which affects its reporting capabilities, whereas Burp Suite is already advancing with new AI features and scanning capabilities that OWASP Zap seems to be lacking."
"The port scanner is a little too slow.​"
 

Pricing and Cost Advice

"AppScan is a little bit expensive. IBM needs to work a little bit on the pricing model, decreasing the license cost."
"The solution is cheap."
"Pricing was the main reason that we went ahead with this solution as they were the lowest in the market."
"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."
"The price is very expensive."
"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 product has premium pricing and could be more competitive."
"Our clients are willing to pay the extra money. It is expensive."
"The tool is open-source."
"It is highly recommended as it is an open source tool."
"The solution’s pricing is high."
"OWASP Zap is free to use."
"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."
"It's free. It's good for us because we don't know what the extent of our use will be yet. It's good to start with something free and easy to use."
"This solution is open source and free."
"This is an open-source solution and can be used free of charge."
