Effective vulnerability identification enhances security scans but AI-driven enhancements are needed
OWASP is only meant for two or three different types of scans. It is a tool which will scan the code for security for vulnerabilities We were able to convince the customers to really remove those rules when GitLab was able to show the results. Customers should be aware that GitLab is not just a…

Quotes from Members

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

Pros

"OWASP is quite matured in identifying the vulnerabilities."
"The API is exceptional."
"They offer free access to some other tools."
"Automatic scanning is a valuable feature and very easy to use."
"OWASP Zap is straightforward to use. If someone doesn't have the budget for tools like Burp Suite, OWASP Zap is an excellent alternative."
"One valuable feature of OWASP Zap is that it is simple to use."
"The solution is good at reporting the vulnerabilities of the application."
"The OWASP's tool is free of cost, which gives it a great advantage, especially for smaller companies to make use of the tool."
"What I like most about AppSpider is that it's easy to use and its automated scan gives me all the details I need to know when it comes to vulnerabilities and their solutions."
"The initial deployment is very straightforward and simple. The product is stable if configured properly."
"The most valuable feature of Rapid7 AppSpider is the vulnerability reporting data. Additionally, the data is reported in a convenient way rather than seeing them as a PDF. We are able to generate all the reports exactly what we want in a flexible way."
"It scans all the components developed within a web application."
"The entire solution is interactive and has a point-and-click user experience, which makes it easy to find items or drill down on information. You don't need specialized skills to use the product."
"One of the most valuable features of AppSpider is its broad range of authentication identification, which is a key reason for its utilization."
"I like the ability the product has to detect vulnerabilities quickly, when it has been released in our environment, then displaying them to us."
"The most valuable feature is the reporting, which is compliant with international standards."
 

Cons

"The automated vulnerability assessments that the application performs needs to be simplified as well as diversified."
"The port scanner is a little too slow.​"
"It needs more robust reporting tools."
"Sometimes, we get some false positives."
"The product should allow users to customize the report based on their needs."
"The work that it does in the limited scope is good, but the scope is very limited in terms of the scanning features. The number of things it tests or finds is limited. They need to make it a more of a mainstream tool that people can use, and they can even think about having it on a proprietary basis. They need to increase the coverage of the scan and the results that it finds. That has always been Zap's limitation. Zap is a very good tool for a beginner, but once you start moving up the ladder where you want further details and you want your scan to show more in-depth results, Zap falls short because its coverage falls short. It does not have the capacity to do more."
"Online documentation can be improved to utilize all features of ZAP and API methods to make use in automation."
"I prefer Burp Suite to SWASP Zap because of the extensive coverage it offers."
"The solution is too slow. It could take a full day to scan. Competitors are much faster."
"Support response times are slow and can be improved."
"There are some glitches with stability, and it is an area for improvement."
"AppSpider has some problems with the RAM needed while scanning."
"The enterprise interface is too simple. It should be more customizable."
"AppSpider could improve in the area of integration. They need to add more integration opportunities."
"It needs better integration with mobile applications."
"This price of this solution is a little bit expensive."
 

Pricing and Cost Advice

"The tool is open-source."
"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."
"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."
"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."
"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."
"The tool is open source."
"The price is pretty fair."
"The price of Rapid7 AppSpider cost 9,000 annually but there is limited usage. Large companies are able to negotiate a better price or a better deal for the usage with the vendor."
"AppSpider is closed-source software and you need to acquire a license in order to use it."
"The licensing cost depends on the number of users."
"It is expensive if you want to buy the Enterprise version that is able to scan multiple applications at once."
