Email, due to its widespread use, is currently the most common way cyber criminals launch and distribute threats, such as phishing, ransomware or spoofing. Email is also a common entry point for attackers looking to gain a foothold in your network to steal valuable company data. As such, the objective of email security is to minimize the likelihood of those threats from entering your company.
Ensuring your email environment remains safe, requires security activities on different fronts. An important technical control is to have an up-to-date antimalware and anti-software protection. Also, the end-users should be regularly trained/reminded on the risks that come with using email to make sure the users remain vigilant when clicking on links embedded in the emails or when opening attachments and to come forward in case the user noted something peculiar.
