Phase 3: Data Normalization and Asset Hygiene

Data normalization and asset hygiene is the third phase of your Tenable One adoption. This phase focuses on merging, de-duplicating, and tagging your asset data to create a clean, accurate, and searchable asset inventory.

Expected Outcomes

During this phase, Tenable Exposure Management processes your raw asset data to ensure accuracy and provide business context. The expected outcomes are:

• Asset tags are standardized and applied (for example, business unit, owner, or environment) for visibility and reporting.

• Asset tags are applied on QA and/or developer assets so they can be filtered in and out when needed.

• Asset coverage is validated against your expected inventory.

Why This Is Important

Clean and accurate asset data is essential for trustworthy reporting, effective prioritization, and clear asset ownership. This phase ensures that the data you see in Tenable One reflects your environment, allowing you to confidently build policies and workflows based on it.

Verification

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

• Asset coverage in Tenable One is near your expected inventory count. For more information, see Assets.

• Tagging is completed and visible in both Tenable Exposure Management and in the respective components (where applicable). For more information, see Manage Tags.
