What is the experience like for teams switching to Tenable Nessus from another tool?

Teams switch to Tenable Nessus from tools such as OpenVAS, Qualys, and Rapid7 products when they want a simpler workflow, broader or more current vulnerability coverage, or findings they consider more accurate. Some also move for better value or to replace tools that were harder to administer, slower to scan, or less consistent in their results.

What features or capabilities could make Tenable Nessus even more useful?

More flexible reporting and management views would make Tenable Nessus easier to use across different audiences and workflows. Users also want improvements that reduce manual follow-up and make scan operations and results easier to manage, including:

Reporting: More customizable reports, clearer summaries and visualizations, and exports that are easier to share with management or assign to teams.
Finding accuracy: Fewer false positives and better handling of cases such as backported patches, so teams spend less time validating results manually.
Workflow and administration: Stronger remediation tracking, scan-history retention controls, and more flexible user roles, tagging, and automation.

Is Tenable Nessus considered safe and secure for handling data?

Tenable Nessus helps security teams identify vulnerabilities, misconfigurations, and patch gaps so they can assess exposure and prioritize remediation. Scan results can still require manual validation, since noisy findings and false positives sometimes add review work.

Nessus helps organizations during the auditing process by providing clear reports of the vulnerabilities as they are found during the scanning. The agent helps detect vulnerable software, misconfigured settings and other security-related issues like patches. It provides the alert along with a CVE score which helps to identify the criticality and impact of the vulnerability on the organization's security.

Nessus plugin contains the vulnerability information with the remediation action which brings easy for the security team to remediate the vulnerability easily. Review collected by and hosted on G2.com.

What do you dislike about Tenable Nessus?

Sometimes when we are scanning the vulnerabilities in a large environment it takes time like 2-3 days to find all the vulnerabilities of the whole environment. The scanning requires downtime from the organization so that it does not affect the production environment as sometimes it brings high traffic which interrupts the production environment.
