Nessus has some great features, like the custom reporting. It’s super helpful for tracking vulnerabilities. I'm just unsure if it's entirely worth the cost yet. It's good but could be a bit better in some areas.

Nessus is solid, can’t deny that! The amount of scanned data is impressive, and the user experience is nice. I like creating scheduled scans. However, it can be a tad overwhelming with all the options sometimes.
