If you wish to use third-party software, configure it while the program is being installed. You can select from a wide variety of encryption software kinds. Before utilizing the software, could you pay close attention to its security?

Understand the Mailing Threats You Are Dealing With

There are new threats every time you send or receive mail. According to research, since 2020, there has been a threefold rise in cyberattacks. People and institutions must be aware of the common assault types. They can then put the best mail security measures into effect. Some of the most common risks are listed here.

  1. Phishing Threats. Every day, cybercriminals send out over 3.4 billion phishing emails. What they want is your data.
  2. Malspam Threats. These are malware-filled spam emails. Cybercriminals affix attachments or links to them. Based on up-to-date data, offenders send out over 162 million spam emails every day.
  3. Spoofing Threats. Cybercriminals send phony-looking emails with certain attributes. Based on the statistics provided, around 30,000 spoofing assaults occur every day. 
  4. Ransomware Threats. Your emails are encrypted by cybercriminals, rendering them unreadable. When the encryption is removed, they demand a ransom. According to data, there will be 37,700 ransomware attacks each hour in 2024.

Conduct the Best Password Management Practices

You can create, store, and use all your passwords using reliable password management software. It will improve password security & usability along with various other mail protection strategies. This helps in creating complex & unique login data. Moreover, you should also employ effective techniques to recollect the login information easily. For this, there are various email security recommendations, such as the following:

  2. Create Complex Login Information: Make complex passwords that are much more difficult for anyone to crack down on.
  3. Don’t Share Your Password with Anyone: Share your passwords with reliable people only with those who truly need to know.
  4. Add an Authentication Layer: Add an extra security layer by using a multi-factor authentication protocol.

Conduct an In-Depth Employee Training Program

Every company should prioritize an employee training program to maintain system security and prevent cyberattacks. The training program will allow the employees to recognize the potential cyber threats and put an end to them. Here are some effective ways to support the employee training program about email security:

  1. Educate them about the dangers and their role in maintaining cyber security.

Implement Multi-Factor Authentication Protocol

Multi-factor email authentication protocols are operational techniques that enhance cyber security from the background. They guarantee the security of every incoming and outgoing mail. Multi-factor authentication protocols guarantee that the emails are legit. Certain emails may be blocked by the protocols or directed to the spam folder if they appear suspicious. Here are some authentication mechanisms that you can employ in your company:

  1. SPF (Sender Policy Framework): It compiles an approved IP address list, and blocks an email coming from a different IP address.  
  2. DKIM (Domain Keys Identified Mail): It adds digital header signatures by receiving servers to confirm email authenticity.
  3. TLS (Transport Layer Security): TLS encrypts email security during delivery to guarantee the system’s complete safety.
  4. DMARC (Domain Message Authentication Reporting and Conformance): DMARC uses SPF & DNS to confirm the email senders’ authenticity.

Add Brand Logo to Emails

Enhancing your users’ trust through logo branding is crucial. Email open rates have significantly increased in the past few months and more professional appearance due to recognizable logos. It is easier for receivers to identify an email sender if it has a verified logo. It reduces the likelihood of clicking on malicious & phishing emails. Most recipients will open their emails when they have faith in the brand.
