Manage Asset Tags

In Tenable.io, asset tags are composed of custom categories and associated values. For example, if you want to group your assets by location, create a Location category with the value Headquarters. Note that this definition of tag is more specific than the more general usage of "tag."

You can use tags to categorize or group assets. Tenable.io does not support using asset tags to define custom attributes for individual assets.

You can assign a tag to assets manually, or you can create dynamic tag rules that Tenable.io uses to automatically assign the tag to assets.

When managing asset tags in Tenable.io, keep in mind the following limits:

Tag categoriescategory100 per Tenable.io instance
Tag valuesvalue100,000 (default)

If your organization wants to change the total tag limit, contact Tenable Support.

Note that individual tag values cannot exceed 50 characters in length.

To manage asset tags:

  1. Create asset tags that reflect your business context. You can apply a tag to assets manually, or you can create dynamic tag rules that Tenable.io uses to automatically assign the tag to assets. To apply tags automatically, use tag rules.
  2. Assign tags to your assets. This step is optional if you create rules to apply tags automatically.
  3. Maintain the tags you've assigned:

🛈

Note

When you create or edit a tag rule, Tenable.io may take some time to apply the tag to existing assets, depending on the system load and the number of matching assets.
