Content categorization and scanning sensitivity level

The algorithms used to perform content categorization and analysis are tuned by Forcepoint Security Labs to provide optimal results for most organizations. If the Optimized setting does not produce the results you expect, however, you can adjust the sensitivity level of the analytics.

The sensitivity levels affect how strictly real-time analysis applies its criteria to determine whether analyzed content contains a threat, or needs to be re-categorized.

• When more strict criteria are used, fewer sites are found to be threats, and fewer sites are re-categorized in real time.

  This may increase the number of false negatives, where risky sites are treated as safe.

• When less strict criteria are used, more sites meet the criteria for threats or re-categorization.

  This may increase the number of false positives, where innocuous sites are treated as risky.

If you are receiving too many false positives, adjust the sensitivity level to the right (more strict). This means that a site will have to meet a higher threshold (match more criteria) to be considered malicious or require re-categorization.

If you believe that sites that should have been blocked are being permitted, adjust the sensitivity level to the left (less strict). This means a site won't have to reach so high a threshold (match fewer criteria) to be considered malicious or require re-categorization.
