Email is among the most common ways to connect online for individuals and companies, however hackers make use of it to infect computers and devices with malware.

This is the reason why email security best methods are crucial to secure your organization and personal accounts from cyberattacks.
Use a link scanner that scans outbound links, and only allows them to be downloaded there (or better to not download them at all). Encryption, an additional step makes sure that anyone who is able to intercept an email or its attachments will not be able to read the contents. It does this by changing plain text into encrypted text. This feature is built into the platforms of all major email providers such as Gmail and Microsoft Outlook/Office365.
Beware of opening any executable file that is included in your email. These files can contain viruses or malware that can harm your computer. If you’re unsure whether an attachment is safe to open, go through a search engine and look for the file name and extension specifically.
It is important that employees use strong passwords to sign in to their accounts. Also ensure that all employees have access to email only on safe devices.
