It is an umbrella phrase that refers to the various policies, practices, and technologies used to safeguard email accounts, information, and communication against unwanted access and loss as well as compromise. Malware, spam, and phishing assaults are frequently distributed through email. Attackers employ false communications to convince recipients to provide sensitive information, open attachments, or click on URLs that direct the recipient’s device to a malicious website where malware is installed. A typical entry route for attackers attempting to build a foothold in an enterprise network and obtain sensitive company data is through email.
Email encryption is the process of encrypting or disguising, the content of email communications to prevent potentially sensitive information from being read by anybody other than the intended receivers of the message. Email encryption is frequently used with authentication.
What Is the Security of Email?
The email was created to be as open and accessible as possible. Organizations can communicate with one another as well as with people from other organizations when they use this technology. The difficulty is that email is not a secure method of communication. This enables attackers to utilize email as a means of causing issues in an attempt to make a monetary gain. Malicious software and phishing attempts, sophisticated targeted attacks, and business email compromise (BEC) are all methods by which attackers attempt to take advantage of the insecure nature of email. Because email is used by the vast majority of businesses to conduct business, attackers target email in an attempt to steal important information.
Because email is an open format, it can be viewed by anyone who can intercept it, resulting in worries about email security. This became a problem as more and more businesses began communicating confidential or sensitive information via electronic means. Intercepting an email allows an attacker to quickly and easily access the contents of the message. Over the years, corporations have increased their email security procedures to make it more difficult for attackers to obtain sensitive or secret information from their systems.

Policies Concerning Email Security
Due to the importance of email in today’s business world, firms have set policies to govern how they handle this information flow between employees. Typically, one of the first restrictions that most firms implement is the prohibition on examining the contents of emails that pass through their email servers. It’s critical to comprehend the entirety of the email to respond appropriately and effectively. Following the implementation of these baseline standards, an organization can implement a variety of security policies on the emails in question.
They can range from simple steps like deleting all executable content from emails to more in-depth activities like forwarding questionable content to a sandboxing tool for in-depth investigation. If these policies detect security issues, the organization must have actionable intelligence about the scope of the assault if it is to take appropriate action. This will aid in determining the extent of any damage that may have been inflicted by the attack. A business can impose email encryption policies to prevent sensitive email information from falling into the wrong hands once it has visibility into all of the emails that are being sent within its network.
Email Security Best Practices are shown below.
Organizations should install a secure email gateway as one of their initial best practices to protect themselves against cyberattacks. An email gateway checks and processes every incoming and outgoing email to ensure that threats are not allowed to enter the system and that it is not compromised. Traditional security measures, such as blocking known bad file attachments, are no longer effective due to the sophistication of today’s attacks. A more effective solution is the implementation of a secure email gateway that employs a multi-layered approach.

Furthermore, as a best practice, it is recommended that you implement an automated email encryption solution. This solution should be capable of analyzing every outbound email traffic to identify whether or not the content is deemed sensitive. If the content is sensitive, it must be encrypted before it can be sent to the intended recipient via the email system. Using this method, even if an attacker manages to intercept emails, they will be unable to view them.
Best Practices for Email Security – Automatic Email Encryption
Training staff on proper email usage and educating them on the difference between a good and bad email is another crucial best practice for maintaining email security. Users may receive a malicious email that manages to get past the secure email gateway, so they must understand what to look for in these messages. The majority of the time, they are subjected to phishing attacks, which can be distinguished by certain characteristics. Employees who have received training can identify and report on these types of emails.
Tools for Encrypting Email
To provide multi-layered protection against unwanted, malicious, and BEC email while also providing granular visibility and business continuity for organizations of all sizes, a secure email gateway should be deployed either on-premises or in the cloud. These controls give security teams the confidence that they can protect users from email threats while also ensuring that email communications are maintained in the case of a system failure.
An email encryption solution lowers the risks associated with regulatory infractions, data loss, and corporate policy violations while maintaining the ability to send and receive critical business messages. It should be suitable for any corporation that wants to protect sensitive data while still making it readily available to affiliates, business partners, and users—on both desktop and mobile devices—through the use of email security solutions. Companies that must adhere to compliance rules such as GDPR, HIPAA, or SOX, or that must adhere to security standards such as PCI-DSS, should consider implementing an email encryption solution to protect their communications.
