Amit Beniwal - PeerSpot reviewer
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.
SubhajitAich - PeerSpot reviewer
A stable solution that can be used for infrastructure vulnerability scanning and web application scanning
Qualys Web Application Scanning is very complex to use, and its graphical interface is not very user-friendly. Compared to other solutions like Tenable and Rapid7, you need to navigate a lot to get the actual results out of Qualys Web Application Scanning. If I have to search for one thing within the entire console, I have to look for it randomly. It's not very easy and very comfortable to find something. Overall, it's a very good solution, but it will be very good if the tool is more user-friendly.

Quotes from Members

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

Pros

"Automatic scanning is a valuable feature and very easy to use."
"It has evolved over the years and recently in the last year they have added, HUD (Heads Up Display)."
"One valuable feature of OWASP Zap is that it is simple to use."
"The application scanning feature is the most valuable feature."
"The scalability of this product is very good."
"The product helps users to scan and fix vulnerabilities in the pipeline."
"The most valuable feature is scanning the URL to drill down all the different sites."
"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."
"It is easy to use."
"​QualysGuard web-based scanner is very useful for performing external penetration and PCI scans from remote locations.​"
"It scans web applications to identify vulnerabilities during deployment."
"The vulnerability management feature is a strong one. And also the patch management feature."
"The most valuable features are the scheduled scanning, detailed reports, asset management, the knowledge database, and the overall product framework."
"Qualys Web Application Scanning is robust and mature from industry standards."
"The most valuable feature is that we are able to scan the services and put credentials like a user ID password. We can verify the vulnerability level."
"It is a very stable solution."
 

Cons

"For scalability, I would rate OWASP Zap between four to five out of ten."
"There are too many false positives."
"The product reporting could be improved."
"The solution is unable to customize reports."
"The forced browse has been incorporated into the program and it is resource-intensive."
"The ability to search the internet for other use cases and to use the solution to make applications more secure should be addressed."
"It would be nice to have a solid SQL injection engine built into Zap."
"I'd like to see a kind of feature where we can just track what our last vulnerability was and how it has improved or not. More reports that can have some kind of base-lining, I think that would be a good feature too. I'm not sure whether it can be achieved and implement but I think that would really help."
"The area of false positives could be improved. There are quite a number of false positives as compared to other solutions. They could probably fine tune the algorithm to be able to reduce the number of false positives being detected."
"The product's pricing could be better."
"It should have better automatic reporting."
"In terms of the Policy Compliance model which they currently have, not all the platforms are being covered. If they could improve on the Policy Compliance model, since there are policies which are benchmarked against it, this will be helpful for us."
"We procured around 110 licenses for Web Application Scanning, but we have issues running concurrent scans. I don't currently have the option to trigger scans for all 100-plus websites. The default limit is around 10 conference scans. It's not very scalable, to be honest, because of the limitation that they put on concurrent scans."
"I would like it to be cheaper because it is a bit expensive compared to competitors like Tenable Nessus."
"In certain cases, this product does have false positives, which the company should work on."
"The authenticated scanning feature could be improved by adding support for real-time scanning tokens and authorization tokens."
 

Pricing and Cost Advice

"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."
"It is open source, and we can scan freely."
"The tool is open-source."
"The solution’s pricing is high."
"The tool is open source."
"As Zap is free and open-source, with tons of features similar to those of commercial solutions, I would definitely recommend trying it out."
"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."
"We normally purchase an annual license."
"Try the free trial of the product to understand the basic working mechanisms.​"
"​It is best to be an institutional buyer and directly contact the sales team, as they can provide over-the-top discounts for bulk orders​."
"The product has a very good licensing model."
"Licensing was based on the number of assets that you want to scan on your network. You can also do licensing on subscription. On subscription, it is easier and more flexible. You tell Qualys that you want to move from the 1000 to 2000 band or the 3000 or 5000 band, then they will give you the quotation for it. Once you pay for it, applying the licensing is quite easy and effective."
"The product pricing is fair and reasonably priced."
"Qualys WAS' pricing is competitive."
"We are on an annual license for the solution and the pricing could be more affordable."
