1- What is Email Security?
Email security is the use of various technologies or policies to protect mailboxes against cyber threats. In today’s digital world, many organizations are using more of a cloud or hybrid email platform and cloud email security is becoming more and more important.

Email security includes a variety of policies, procedures, and techniques to protect email accounts and email content from unauthorized access. Email security solutions are often used to stop malware, spam, and phishing attacks. Attackers often use deceptive messages to persuade victims to provide sensitive information, open attachments, or click links that allow them to install malware on their devices. Email is the most important entry point to obtain valuable company data in the organization.
3- How Secure are Email Services?
Email service platforms are open and accessible. It allows employees in institutions to communicate with each other and with people in other institutions. However, email is by no means a secure method of communication. Cyber attackers view email as the most important tool to attempt to make a profit. Attackers try to explain email security through spam campaigns, malware and phishing attacks, and various spear-phishing tactics. Because most organizations operate over email, attackers target email to steal sensitive information.
4- How can email security be compromised?
Many cybersecurity experts declare in various reports that phishing emails, malware, ransomware, BEC attacks and other threats are the most important risks. Tools that monitor data protection and secure outbound traffic are also important. In general, there are four main elements that can be compromised:
- Email body
- Email attachments
- URLs found in the email
- Sender’s email address
5. How Should Email Security Policies Be?
Because email is so critical in today’s business world, organizations must build the right policies on how to protect this flow of information. One of the first email security policies most organizations established was often to control the content of outgoing and incoming emails from email servers.
It is important to understand what is in the email in order to take the right action. Once this is done the basic policies, institutions can implement a variety of security policies on emails.
Email security policies are generally to remove malicious content from emails, analyze suspicious email content in detail, and use the right tools for these actions. These policies should also include the use of cyber threat sharing or threat intelligence tools. Thus, the email vulnerabilities that may arise can be detected in advance.
6. What Are the Best Email Security Practices?
Using an automated email encryption tool as a practice is an important thing to consider. Such products are able to analyze all outgoing email traffic to determine whether the sent content is sensitive information, and sensitive-detected emails are encrypted before being sent to the target user by email. The attackers will not view the encrypted email content at this stage even if they have somehow compromised.
Training employees on the correct and safe use of email and providing them with the necessary means to know which email is malicious or non-malicious is also an important best practice for email security.
When users receive a malicious email that bypassing through the secure email gateway, they will be responsible to prevent these attacks from happening as the last line of defense. They will also be successful in preventing many attacks if they know where to look first. Cybersecurity training helps employees detect and report such malicious emails.
Cyber threat intelligence has an important place among email security best practices. With this tool, possible threats are eliminated in advance.
