Attractive automated reports with boost user productivity and an easy setup
The primary use is mainly related to vulnerability assessment, including both public and internal IP addresses By using this tool, we have reduced the workload and increased the productivity of users. It generates automated reports. This feature is beneficial when sharing reports with clients as…
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.

Quotes from Members

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

Pros

"We use the solution for the scanning of vulnerabilities like SQL injections."
"The most important feature is that it's a web-based graphical user interface. That is a great addition. Also, the ability to schedule scans is great."
"The most valuable feature of Acunetix is the UI and the scan results are simple."
"It comes equipped with an internal applicator, which automatically identifies and addresses vulnerabilities within the program."
"It's very user-friendly for the testing teams. It's very easy for them to understand things and to fix vulnerabilities."
"Acunetix has an awesome crawler. It gives a referral site map of near targets and also goes really deep to find all the inputs without issues. This was valuable because it helped me find some files or directories, like web admin panels without authentication, which were hidden."
"The features of Acunetix have proved most effective in identifying vulnerabilities."
"I find it to be one of the most comprehensive tools, with support for manual intervention."
"OWASP Zap is straightforward to use. If someone doesn't have the budget for tools like Burp Suite, OWASP Zap is an excellent alternative."
"The most valuable feature is scanning the URL to drill down all the different sites."
"Automatic updates and pull request analysis."
"It scans while you navigate, then you can save the requests performed and work with them later."
"ZAP is easy to use. The automated scan is a powerful feature. You can simulate attacks with various parameters. ZAP integrates well with SonarQube."
"Fuzzer and Java APIs help a lot with our custom needs."
"It's great that we can use it with Portswigger Burp."
"The API is exceptional."
 

Cons

"The only problem that they have is the price. It is a bit expensive, and you cannot change the number of applications for the whole year."
"The solution limits the number of scans. It would be much better if we could have unlimited scans."
"We want to see how much bandwidth usage it consumes. When we monitor traffic we have issues with the consumption and throttling of the traffic."
"It should be easier to recreate something manually, with the manual tool, because Acunetix is an automatic tool. If it finds something, it should be easier to manually replicate it. Sometimes you don't get the raw data from the input and output, so that could be improved."
"We have had issues during upgrades where their scans worked on some apps better with previous versions. Then, we had to work with their tech support, who were great, to get it fixed for the next version."
"Acunetix needs to be dynamic with JavaScript code, unlike Netsparker which can scan complex agents."
"You can't actually change your password after you've set it unless you go back into the administration account and you change it there. Thus, if you're locked out and don't remember your password, that's a thing."
"Currently only supports web scanning."
"There isn't too much information about it online."
"As security evolves, we would like DevOps built into it. As of now, Zap does not provide this."
"Too many false positives; test reports could be improved."
"The automated vulnerability assessments that the application performs needs to be simplified as well as diversified."
"Online documentation can be improved to utilize all features of ZAP and API methods to make use in automation."
"Zap could improve by providing better reports for security and recommendations for the vulnerabilities."
"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."
"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."
 

Pricing and Cost Advice

"Implementing Acunetix needs a medium or larger business agency, because you need some money to get Acunetix. It is costly, but if you care about your agency's security, then maybe it's a cost that might help you in the future."
"When we looked at all other vendors and what they were asking for, to provide a third of what Acunetix was capable of doing, it was an easy decision... But now that it's coming to a cost where it's line with market value, it becomes more of a competition... Acunetix is raising the cost of licensing. It's 3.5 times what we were initially quoted."
"The cost is based on two types of licenses, ConsultLite, and ConsultPlus, as well as the number of domains that are scanned."
"The pricing and licensing are reasonable to a point. In order to run multiple scans at a time, we are going to have to purchase a 100 count license, which is an overkill. Though, compared to what we were paying for, the cost seems reasonable."
"The pricing is a little high, and moreover, it's kind of domain-based."
"It is a bit expensive. If you need to check five applications, you have to pay almost 14,000. It is an agreement for two years at 7,000 per year for only five applications. You cannot change the applications in the license. So, you are stuck with the same license for the five applications for one full year."
"When compared with other products, the pricing is a little bit high. But it gives value for the price. It serves the purpose and is worthwhile for the price we pay."
"I would say that Acunetix is expensive because there are products on the market with similar features that are equally or better-priced."
"It is highly recommended as it is an open source tool."
"The tool is open-source."
"OWASP ZAP is a free tool provided by OWASP’s engineers and experts. There is an option to donate."
"The solution’s pricing is high."
"It is open source, and we can scan freely."
"This app is completely free and open source. So there is no question about any pricing."
"As Zap is free and open-source, with tons of features similar to those of commercial solutions, I would definitely recommend trying it out."
"The tool is open source."
