Abstract
Methods and systems are provided for securing email communications. According to one embodiment, a network device receives an outbound email originated by a computing device of an internal network and directed to a target recipient. It is determined whether a domain name of the target recipient is present in a global doppelganger database. When the domain name is determined to be present in the global doppelganger database, transmission of the outbound email to the target recipient is prevented if the domain name is an unacceptable domain name and transmission of the outbound email to the target recipient is permitted if the domain name is an acceptable domain name.
Claims22
A method for securing electronic mail (email) communications comprising:
- receiving, by a network device, an outbound email originated by a computing device of an internal network and directed to a target recipient;
- determining, by the network device, whether a domain name of the target recipient is present in a global doppelganger database;
- when the domain name is determined to be present in the global doppelganger database, preventing transmission of the outbound email to the target recipient if the domain name is an unacceptable domain name and transmitting the outbound email to the target recipient if the domain name is an acceptable domain name.
A non-transitory computer-readable storage medium tangibly embodying a set of instructions, which when executed by one or more processors of a network device, cause the one or more processors to perform a method comprising:
- receiving, by a network device, an outbound email originated by a computing device of an internal network and directed to a target recipient;
- determining, by the network device, whether a domain name of the target recipient is present in a global doppelganger database;
- when the domain name is determined to be present in the global doppelganger database, preventing transmission of the outbound email to the target recipient if the domain name is an unacceptable domain name and transmitting the outbound email to the target recipient if the domain name is an acceptable domain name.
