It’s very user-friendly to start a basic scan of IP addresses. As a non-developer, I was able to learn the interface quickly and run the scan without much effort. The reports are audit-friendly, and we were able to submit them for compliance purposes. Review collected by and hosted on G2.com.
The report is provided in PDF format, so we’re not able to assign specific vulnerabilities to the appropriate teams. It would be very helpful if the reports could also be exported to a format like Excel, so we can allocate vulnerabilities to the respective team members more easily.

I think Tenable Nessus is a very popular toolset that stands out because of its usability, allowing me to learn and use it quickly without requiring extensive training or facing a steep learning curve. Its intuitive nature facilitates swift adoption, making it accessible for our team. Additionally, I value the ability to specify the range of IP address assets and perform both ad-hoc and scheduled scanning. This functionality is crucial for maintaining the integrity and security of our network infrastructure, and it helps us in managing and mitigating vulnerabilities efficiently.

I dislike that the pricing of Tenable Nessus has been going up quite significantly recently. Review collected by and hosted on G2.com.
