KnowBe4 Launches PhishML to Help Identify and Assess Dangerous Messages

PhishML is a machine-learning module within KnowBe4’s PhishER platform that makes prioritization of suspicious messages easier, faster and more accurate

KnowBe4, the provider of the world’s largest security awareness training and simulated phishing platform, today announced PhishML (Machine Learning), a new machine-learning module within the PhishER platform to help security professionals identify and assess suspicious messages.

PhishML analyzes every message coming into the PhishER platform and gives security professionals the information they need to make prioritization easier, faster and more accurate. This machine-learning module constantly learns based on messages that are tagged by security professionals in the PhishER user community. PhishML will assign tags along with confidence levels using the data from all user-reported email messages. By using the default settings, PhishML will tag more than half of reported messages and has a current prediction accuracy of more than 95%.PhishML-1

“Approximately 10 percent of suspicious email messages are getting through spam filters,” said Stu Sjouwerman, CEO, KnowBe4. “That means users are the last line of defense, so they need to be aware of what to look out for when it comes to phishing and other social engineering attacks. The benefits of the PhishML module coupled with our robust PhishER platform include making the identification of real threats a much quicker and more accurate process.”

PhishML is available to KnowBe4’s PhishER customers at no additional cost. For more information on PhishML, visit
