Provides detailed reports that improve code maintainability while needing better coverage reports and technical support

Tenable.io Web Application Scanning provides a detailed report, identifying functions that are complex and need to be more maintainable and readable. It offers features such as generating an executive summary and detailed reports highlighting issues in specific lines of the code. However, it does not provide coverage reports in the free version, which is a limitation.

Quotes from Members

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

Pros

"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."

"The solution is highly stable, rated at ten out of ten."

"When it is set up properly, it can do scanning on web apps with multiple engines automatically."

"I like the ability the product has to detect vulnerabilities quickly, when it has been released in our environment, then displaying them to us."

"I would say that it is stable, as I am not aware of any major issues."

"It scans all the components developed within a web application."

"The setup is usually straightforward."

"Rapid7 AppSpider is good at managing different applications. It uses applets and generates reports to cover the PCA/GDPR compliance requirements."

More Rapid7 AppSpider pros

"All the features are valuable to us as they offer cutting-edge scanning methods and address the latest issues with a contemporary approach. Tenable.io Web Application Scanning is highly stable. I rate it a nine out ten. Since the solution works on the Cloud, it's highly scalable. I rate the scalability a nine out of ten. The setup of the solution is straightforward. The Return on Investment is substantial. I recommend the solution to all."

"We can get detailed information about vulnerabilities."

"Our customers adopt this solution because of the replication testing and the vulnerability assessment it can do. It is a multi-faceted product."

"The most effective feature of the product is the ability to scan the entire environment."

"The initial setup is straightforward."

"It collects the vulnerabilities on the hostnames and sends them to the Tenable.io cloud. Tenable has its own cloud where Tenable.io is running, but there are many connectors to other cloud solutions. Tenable can do vulnerability scanning for other cloud managers such as Azure, Amazon, and so on."

"Tenable.io Web Application Scanning is very easy to use."

"The solution is stable."

Cons

"The enterprise interface is too simple. It should be more customizable."

"For Japanese customers, localization is needed. The product should offer a GUI in Japanese and provide Japanese reports for end-users."

"Support response times are slow and can be improved."

"One of the challenges I have with AppSpider is that it gives you a lot of false positives, especially when compared to other solutions."

"AppSpider could improve in the area of integration. They need to add more integration opportunities."

"Integration could be better."

"This price of this solution is a little bit expensive."

"It needs better integration with mobile applications."

More Rapid7 AppSpider cons

"Tenable.io Web Application Scanning conducts a general scan, which wastes time. The scan needs to be specific."

"The technical support should be improved. Currently, some attacks are detected while others are not."

"The technical support needs improvement. Currently, it takes time, which might be due to the free version, but providing some level of support could encourage future purchase decisions."

"It isn't easy to manage vulnerabilities in Tenable."

"Tenable.io Web Application Scanning could improve by offering faster fuzzing."

"The report customization needs to be better."

"I would like for them to add proxy filtering, where you can transfer and alter the package. It is fully automated. Other web application testers programs are actually proxy software, and the proxy software gives you the flexibility of modifying the outgoing package, which will actually help you in exploiting any vulnerability in detail."

"The market is standard for vulnerability scanning, however, the posture can be improved through Tenable's prioritization engine."

More Tenable.io Web Application Scanning cons
