- _Medium – 40 and higher_ (default value)
- _High – 25 and higher_

Each threshold (_Low_, _Medium_, and _High_) has an associated value (_60_, _40_, and _25_, respectively). Configuring a _Low_ threshold means that more rules will have to match the current request for the WAF to apply the configured ruleset action. For an example, refer to [OWASP evaluation example](/waf/managed-rules/reference/owasp-core-ruleset/example/).
Each threshold (_Low_, _Medium_, and _High_) has an associated value (_60_, _40_, and _25_, respectively). Configuring a _Low_ threshold means that more rules will have to match the current request for the WAF to apply the configured ruleset action.

When the OWASP Anomaly Score Threshold is set to _High_, file uploads may trigger the `949110: Inbound Anomaly Score Exceeded` rule due to the lower amount of scoring rules needed. Consider adjusting the threshold level, [adjusting individual rules](/waf/managed-rules/deploy-zone-dashboard/#configure-a-single-rule-in-a-managed-ruleset) in the ruleset, or [creating an exception](/waf/managed-rules/waf-exceptions/) if excessive false positives occur.

For an example, refer to [OWASP evaluation example](/waf/managed-rules/reference/owasp-core-ruleset/example/).
