Dynamic Message Analysis Platform for Enhanced Enterprise Security

Abstract:

Aspects of the disclosure relate to dynamic message analysis using machine learning. A computing platform may apply a security scoring process to an endpoint relationship to compute a weighted security score for the endpoint relationship. Subsequently, the computing platform may determine a weighted grade for the endpoint relationship based on the weighted security score for the endpoint relationship. Based on identifying that the weighted grade exceeds a predetermined threshold, the computing platform may tag the endpoint relationship as compromised. Subsequently, the computing platform may monitor an electronic messaging server to detect messages corresponding to the compromised endpoint relationship. Based on detecting that the electronic messaging server has received a first message, corresponding to an endpoint of the compromised endpoint relationship, the computing platform may rewrite a URL included in the first message to point to a security service that is configured to open the URL in an isolation environment.
