### "Nessus: Vulnerability Scanner with Appealing Reporting Capabilities" — 4.0/5

> **Wassim** | *29 juillet 2023* | Réseaux informatiques | Taux de recommandation : 9.0/10
> 
> **Avantages**: I used Nessus with nmap for testing the vulnerability of virtualized networks in controlled environments. The main motivation behind the selection of Nessus is to have a user-friendly vulnerability report with categorized network exploits and OS weaknesses. Nessus provides accurate results (though some false positives are noticed in hardened Linux environments). The advanced reporting capabilities in Nessus makes the vulnerability results easily exported and documented to relational databases. Moreover, the various Nessus reports can be compared after hardening the OS with different security configurations.
> 
> **Inconvénients**: Nessus is very accurate but sometimes, especially with latest versions of Ubuntu, many false positives are noticed. Still Nessus results are considered highly informative and the false positives can be autonomously filtered to provide more accurate vulnerability analysis and reporting.
> 
> Nessus is a must for network security testing and vulnerability analysis. Together with Nmap, Nessus gives a much better penetration testing and vulnerability analysis of networks and virtualized cloud infrastructures.
