Abstract
A first data communication of a first connected device related to a first target website is intercepted. The first data communication identifies the first target website by a first fully qualified domain name (FQDN), and the first FQDN is mapped to a first Internet protocol (IP) address. A pair of the first FQDN and the first IP address is determined. A second data communication of a second connected device related to a second target website is intercepted. The second data communication comprises a second encrypted FQDN and a second IP address of the second target website. The second IP address is determined to be equal to the first IP address. A cybersecurity reputation of the second target website is retrieved based on the first FQDN. In response to determining that the reputation matches a predetermined alarm condition, a cybersecurity operation is enforced for the second data communication.
