What is the default recommended number of assets that a single Nessus scanner can handle?

A single Nessus scanner is typically recommended to handle up to 30 assets by default. This recommendation is based on the scanner's ability to effectively manage scans while maintaining optimal performance and accuracy. As the number of assets increases, the potential for resource strain also rises, which may impact scan speed and thoroughness. By allocating the scanner to around 30 assets, users can ensure a more efficient and effective scanning process, leading to better vulnerability management outcomes.

Handling fewer assets also allows administrators to focus on the quality of scan results and minimize the chances of overwhelming the scanner, which can lead to incomplete scans or failure to detect vulnerabilities accurately. Thus, maintaining this balance is crucial for achieving successful vulnerability assessments with Nessus.
