We use the following criteria to evaluate this product:
Cost considerations
An annual $4.4 K Nessus Professional license covers unlimited scans, undercutting per-asset competitors. Web-app, cloud and attack-surface coverage demand the $6.4 K Expert tier, so some capabilities cost extra. The combination keeps overall spend competitive but not the rock-bottom benchmark seen with products that bundle every module up-front

Functionality
Nessus runs credentialed network and agent scans on a regular cadence and tiers findings with Tenable’s Vulnerability Priority Rating to spotlight higher-risk issues. The Expert edition also assesses AWS, Azure, GCP assets and container images, giving coverage beyond on-prem servers. Native connectors feed high-severity results into ServiceNow tickets for remediation but asset discovery is still scan-based rather than real-time, so Functionality sits just below the top tier

Compatibility
Nessus agents run on Windows, Linux and macOS and the REST API allows findings to be retrieved by other tools. Cloud environments can be assessed once credentials are provided, yet purpose-built connectors are limited. Exports to CMDBs or SIEMs rely on CSV files or custom scripts, so extra integration work is typical.

User experience
Nessus provides dashboards and scan views but deeper analysis demands multiple navigation steps. Most reviewers mention a moderate learning curve, with security staff needing tutorials before they can customise scans or reports. Report formatting and vulnerability prioritisation often require manual tweaks, so workflows feel functional rather than truly streamlined.

Customer support
Tenable provides 24×7 phone, chat and portal help, and Premier or Elite plans include a named senior engineer who knows the customer environment. New plugins are normally released within about 24 hours of a vulnerability disclosure, so coverage keeps pace with fresh CVEs. Combined, these offerings place Nessus at the top tier of customer support among vulnerability scanners.
