Centralized license management transforms asset manipulation based on functions and improves security posture

Now that the license is centralized, it's a significant feature to manipulate assets based on their functions. It provides a centralized view from end-to-end to its assets' identities and vulnerabilities. One of the greatest features is Kubernetes. The automated scanning capability is pretty standard in the market, and Tenable's prioritization engine helps improve the security posture.

More Rapid7 AppSpider pros

Cons

"The dashboard and interface are crucial and they need some improvement."

"The product should offer a GUI in Japanese and provide Japanese reports for end-users."

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

"The solution is too slow. It could take a full day to scan. Competitors are much faster."

"The tech support is responsive but issues remain unresolved."

"There are some glitches with stability, and it is an area for improvement."

"The product needs to be able to scale for large companies, like ours. We have millions of IP addresses that need to be scanned, and the scalability is not great."

More Rapid7 AppSpider cons

"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 platform's technical support services could be better."

"The dashboard could be more user-friendly."

"Sometimes it lags with different cloud environments."

"It would be great if there were a dashboard that is more user-friendly."

"We have encountered some problems with the technical support from Tenable; I would rate it a five out of ten. It is not efficacious, especially the first-level support."

"Tenable.io Web Application Scanning is not very user-friendly and you need a lot of information to get proper reports. The tool's support is not very responsive."

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