Phase 6: Validation and Tuning

Validation and tuning is the sixth phase of your Tenable One adoption. This phase focuses on validating the data quality and accuracy within the platform and reducing noise to ensure you are receiving trusted, actionable intelligence.

Expected Outcomes

During this phase, you fine-tune the platform to align with your organization's specific environment and operational realities. The expected outcomes include:

• A sample of potentially known exposures is confirmed to be present in Tenable One.

• The exposure score trendline behaves predictably after an intentional remediation activity (in other words, the score improves).

• Potential false positives are tuned using recast or accept rules. For more information, see Recast Rules.

• Platform performance validation is complete, ensuring dashboards and queries load within expected timeframes.

Why This Is Important

This phase builds trust in the platform. By validating data, tuning potential false positives, and ensuring performance, you give your security and IT teams confidence that the information from Tenable One is accurate, reliable, and actionable.

Verification

You can verify the success of this phase by confirming the following:

• Your organization's internal procedures are used to validate that findings align with expected vulnerabilities.

• The exposure score trendline is growing, mapping days (or weeks/months) of change. For more information, see Exposure View and Remediation SLA.

  Note: Keep in mind that Tenable Exposure Management updates data using a specific cadence. For more information, see Data Timing.
