It was very cheap.
In the past, Vicarius vRx was cheap, but now they have adjusted their pricing policy, resulting in higher renewal costs.
From a pricing perspective, Vicarius was cheaper compared to other competitors.
This view of risk helps reduce the work we would have to do to combine multiple sources to prioritize risk.
It will help cybersecurity professionals monitor the cloud and find vulnerabilities.
We are enjoying the new feature, FlexScan, which is valuable for Internet-facing VMs.
I mostly use the configuration audit feature for the audit configuration as a scan policy, and I will use it for credential audit, which helps me scan credentials access such as local administrator or root access, performing a deeper and more accurate check of local configuration settings and file systems, making it a highly recommended feature.
The scanning and reporting features are the most valuable aspects of Tenable Nessus.
The most valuable features of Tenable Nessus include its ease of access and quick usability.
It's a valuable tool that reduces tension between IT and security teams by providing time to properly install patches.
