Systems, apparatus, articles of manufacture, and methods are disclosed to improve the efficiency of an
artificial intelligence-based
threat detection model. An example apparatus includes interface circuitry,
machine readable instructions, and programmable circuitry to at least one of instantiate or execute the
machine readable instructions to: obtain an
email address from a group of email addresses to be considered as candidates for adding to the
list of non-suspicious email addresses, determine that
a domain of the
email address is indicative of a non-email service providing entity, determine that the
email address has a policy configured for
a domain-based message
authentication, reporting, and conformance (DMARC)
record, add the email address associated to the
list of non-suspicious email addresses, and cause the
artificial intelligence-based
threat detection model to skip an analysis of an email associated with the email address.
