"Comprehensive Vulnerability Scanning with Actionable Remediation Guidance"

5/5

What do you like best about Tenable Nessus?

What I like most about Nessus is its comprehensive vulnerability scanning engine and the depth of information provided in scan results. We regularly use authenticated scans, compliance audits, and scheduled vulnerability assessments to identify security weaknesses across servers, network devices, and Linux systems. The remediation guidance included with each finding is particularly valuable because it helps our team quickly understand the risk and determine the appropriate corrective action.

What do you dislike about Tenable Nessus?

One area where Nessus could improve is reporting and dashboard customization. While the platform provides detailed technical reports that are useful for security teams, creating tailored reports for different audiences can be cumbersome. For example, infrastructure teams often need detailed remediation information, while management prefers high-level risk summaries and trends, which may require additional manual customization.

What problems is Tenable Nessus solving and how is that benefiting you?

Before implementing Nessus, our vulnerability assessment process was largely manual and reactive. We struggled to maintain consistent visibility across servers, network devices, and endpoint systems, which made it difficult to identify vulnerabilities quickly and prioritize remediation efforts effectively. After deploying Nessus, we were able to automate vulnerability scanning and centralize security assessments. We now run scheduled authenticated scans on a regular basis and receive detailed reports that help us identify critical vulnerabilities, missing patches, and misconfigurations much faster than before.
