Emails and the account they are sent from contain a wealth of sensitive data. If a hacker obtains access to them, the result can be catastrophic for companies with considerable data breach on their hands. Email is also a favoured attack vector for threat actors, who launch schemes and scams at companies through this commonly used communication channel.

From protecting the data they contain to defending them against attack, the following are some of the key forms of security associated with email accounts and correspondence:

Spam filters

A substantial proportion of emails received by businesses are marketing devices. These sales emails can clog inboxes to the extent that important, essential, and even official emails are missed. Additionally, cybercriminals use these marketing messages to push out phishing emails. Unsuspecting users often open these malicious emails and click on harmful links included in content and attachments. This can lead to a wide range of issues, from compromising company bank accounts to systems being locked down with ransomware.

Installing state-of-the-art spam filters can assist in separating marketing mails from phishing messages by sending them to a dedicated inbox designed for them.

A crucial email security tool is the ability to schedule spam deletion without ever needing to open emails. This eliminates any risk of dangerous interactions.


While spam filters can separate spam messages from regular mail and delete them eventually, this will take time. For as long as a malicious email is located on a company device awaiting deletion, a threat exists that a user may open the harmful message and interact with its attachment. If the user clicks on a link, it may download dangerous malware onto their device and spread through the company network.

Formidable anti-virus protection can help. This type of program scans outgoing and incoming email for harmful content and blocks its exit or entry. This adds an extra layer of defence as it can eradicate the risk of any viruses undetected by spam filters reaching company networks.


Email data is typically most vulnerable when it’s in a state of transit. If it is sent in open format and cybercriminals intercept a company’s messages, they can easily access confidential data. However, end-to-end encryption ensures that the email can only be viewed by the sender and their intended recipient who have been assigned a decryption key.

The encryption software scrambles the body content of emails, as well as any documents attached, making them unintelligible by anyone without permissions. If an encrypted business email is mistakenly sent to an incorrect address or is intercepted by a malicious actor, the company transmitting it will experience no data breach. Additionally, if firms encrypt all their emails, even if their accounts are hacked, no information will be exposed.
