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

"The security and the dashboard are the most valuable features."
"The product is useful, particularly in its sensitivity and scanning capabilities."
"I mainly use AppScan for vulnerability scanning and database bridging."
"The solution offers services in a few specific development languages."
"AppScan seems to be very good at detecting reflected XSS vulnerabilities."
"We use it as a security testing application."
"SAST is the only feature that works using the on-prem version."
"From the point of view of quality, very excellent quality, it's above all the tools that I have worked with."
"The automatic scanning is a valuable feature and very easy, and the major advantage to this solution is the privacy it offers."
"We use OWASP Zap for web application security scanning."
"Technical support is excellent."
"This solution is providing us with value and as long as it continues to do so, we'll continue to use it."
"The solution has tightened our security and that of our clients who depend on it."
"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."
"This solution has improved my organization because it has made us feel safer doing frequent deployments for web applications. If we have something really big, we might get some professional company in to help us but if we're releasing small products, we will check it ourselves with Zap. It makes it easier and safer."
"You can run it against multiple targets."
 

Cons

"I would love to see more containers. Many of the tools are great, they require an amount of configuration, setup and infrastructure. If most the applications were in a container, I think everything would be a little bit faster, because all our clients are now using containers."
"Improving usability could enhance the overall experience with AppScan. It would be beneficial to make the solution more user-friendly, ensuring that everyone can easily navigate and utilize its features."
"The tool should improve its output. Scanning is not a challenge anymore since there are many such tools available in the market. The product needs to focus on how its output is being used by end users. It should be also more user-friendly. One of the major challenges is in the tool's integration with applications that need to be scanned. Sometimes, the scanning is not proper."
"​IBM Security AppScan Source is rather hard to use​."
"A desktop version should be added."
"I think it's a little bit complex, and that's quite a common issue with most of the IBM products."
"There is one feature called SCA, which stands for Software Composition Analysis, that could be improved."
"They could add a software component analysis tool."
"Right now, I can't give it off to a team and expect them to give me a report that I'm happy with."
"It would be nice to have a solid SQL injection engine built into Zap."
"Too many false positives; test reports could be improved."
"I prefer Burp Suite to SWASP Zap because of the extensive coverage it offers."
"As security evolves, we would like DevOps built into it. As of now, Zap does not provide this."
"The reporting feature could be more descriptive."
"The product should allow users to customize the report based on their needs."
"They stopped their support for a short period. They've recently started to come back again. In the early days, support was much better."
 

Pricing and Cost Advice

"With the features, that they offer, and the support, they offer, AppScan pricing is on a higher level."
"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."
"The solution is moderately priced."
"Pricing was the main reason that we went ahead with this solution as they were the lowest in the market."
"The product is moderately priced, though it's an investment due to extensive code analysis needs."
"HCL AppScan is expensive."
"The price is very expensive."
"The tool is open source."
"It is highly recommended as it is an open source tool."
"As Zap is free and open-source, with tons of features similar to those of commercial solutions, I would definitely recommend trying it out."
"This app is completely free and open source. So there is no question about any pricing."
"OWASP Zap is free to use."
"It is open source, and we can scan freely."
"OWASP ZAP is a free tool provided by OWASP’s engineers and experts. There is an option to donate."
"This is an open-source solution and can be used free of charge."
