This work proposes a methodology for the implementation of a set of rules and filters applied on a Gateway to mitigate the main cyberattacks originated through emails, such as: malware, spam, phishing, and includes information leakage. Through a comparative analysis of the tools that face these cyberattacks, ”Proxmox Email Gateway” is selected to be implemented in two test scenarios, the first without applying the methodology, and the second with its application, in which several Controlled cyberattacks of each of those previously defined. According to data obtained from the test scenarios, it was found that the application of this set of rules reduces cyberattacks by 38.75%, and with the statistical chi-square test with a confidence level of 95% it is shown that the set of filters and elaborate rules applied on a Gateway if it reduces the percentage of the amount of cyberattacks originated through e-mail.
