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.

"The solution's instant reports feature is the most effective for detecting threats."

"We can get detailed information about vulnerabilities."

Cons

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

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

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

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

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

"AppSpider has some problems with the RAM needed while scanning."

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

"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

"Sometimes it lags with different cloud environments."

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

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

"They have a general dashboard for web application scanning, but the dashboards and reporting can be improved. They probably have some features in their roadmap."

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

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

"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 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."

"The price is pretty fair."

"Tenable.io Web Application Scanning is expensive for small businesses."

"The application is extremely affordable. There are no additional costs involved with licensing. We switched to Tenable.io Web Application Scanning from other solutions due to pricing."
