What is Email Security?

Email security refers to the set of security policies that protect the access and contents of an email. It safeguards individuals and organizations from spam, phishing attacks, viruses, and, most of all, data theft.

Email security is a broad term that needs to be discussed in a detailed manner to get a closer look at how it really works. Here are some of the measures deployed to ensure email security.

Buy Antivirus
  1. Buy Antivirus Software
  2. Once a virus enters an email server, it can wreak havoc on a company’s technology infrastructure. It will be too costly for a company to be infiltrated with a virus, not just financially, but on their public image as well. With that threat, you need to buy antivirus that is versatile, reliable, and uncompromising.

    Comodo Internet Security proves to be a fitting partner when it comes to securing its clients from various digital threats. It has provided various tools for individuals and companies to combat multiple threats that pose a danger to their digital resources.

    Today, Comodo has rolled out another feature called Antispam Gateway that would further help companies combat cyber threats. It is designed for organizations that manage their own mail servers and need reliable protection.

  3. Data Encryption
  4. The sharing of highly-sensitive and private information through email is a vital part of a company’s daily operations. Though it provides speed and convenience, it also has one major drawback: hackers can possibly intercept this information.

    To plug the security loopholes on vital information sharing, you can use data encryption on all the emails that a company manages. This way, all the contents inside these emails are tightly sealed and cannot be stolen.

  5. Spam Filters
  6. Spam filters help companies decrease the impact of disruptions caused by spam messages. They have the ability to determine and block unsolicited, unwanted, and virus-infested emails called spam. Small and medium sized businesses (SMBs) use this tool as part of their email security to protect their employees and networks. Spam filters are applied to emails entering and exiting the network.

    Modern spam filters can really be unforgiving, and once it detected unwanted content, it can automatically block the sender’s email address. It also moves such content on a separate folder within the user’s inbox or gives you the option to delete the message from the email server if deemed necessary. To get spam filters, users may buy antivirus software that features reliable anti-spam capabilities to further protect their digital assets.

  7. Use Strong Secure Passwords and Multiple Authentication
  8. Make use of strong passwords to prevent hackers from getting into your system. The longer and more complex passwords are, the better it is for your email security. Create passwords that are at least eight characters long with upper and lowercase letters, numbers, and a few symbols. As much as possible, do not use passwords that are associated with birthdays or other dates and information that can be traced back to you. If you have a hard time memorizing your passwords, use password managers.

    Another email security best practice is applying two-factor authentication. This requires users to input another code into the system apart from the password. The additional code can keep important company information away from the wrong hands.

  9. Virtual Private Network
  10. You can be confident that your email is secured by using Virtual Private Network (VPN) and their useful features. How? Multiple VPN tunneling protocols along with strong encryption algorithms can make that happen. While you are sending and receiving messages, a reliable VPN can defend you against any interception. As such, when working remotely or on a personal device, you must see to it that you have a VPN software to keep you secured while accessing corporate email.

  11. Train Your Employees
  12. Conduct proper employee training to educate them about potential cybersecurity threats as well as the importance of buying antivirus software. The training should include simulations of phishing attacks and regular refreshers about strict policies for them to be aware of unsafe behaviors that can compromise your security.


By deploying those best email security practices above, you can reduce the risks associated with email. Utilizing both software and hardware defenses can keep computers safe and the business running smoothly.
