Tag Rules

Tag rules allow Tenable Web App Scanning to automatically apply tags you create to the assets on your instance that match the tags rules. These automatically applied tags are called dynamic or automatic tags.

Tag rules are composed of one or more filter-value pairs based on asset attributes. When you create a rule and add it to a tag, Tenable Web App Scanning applies the tag to all assets on your instance that match the tag rule.

Note: Tenable Web App Scanning supports a maximum of 35 rules per tag. This limit means that you can specify a maximum of 35 and or or conditions for a single tag value. Additionally, Tenable Web App Scanning supports a default maximum of 25 values per individual tag rule. For IPv4, IPv6, and FQDNs, Tenable Web App Scanning supports a maximum of 1,024 values per individual tag rule.
