[For File Transfer] Why Email is Not Secure?


Email, with its simplest but powerful functions, is the most widely used way for people to transfer content worldwide. People send videos, files, and business messages by email every day. But can you say that email is entirely secure to protect your file assets?

The answer is probably no. Below I list five reasons why email is not safe.

Why Email Is Not Safe

1.The Sender Has No Control

Once your email has arrived in the receiver’s email box, you can not control everything. Your emails can be sent to others or printed, your files or videos can be downloaded unlimited and you'll never know who and when to do it. Things can get out of hand.

2.Email Protocol Does Not Support End To End Encryption

End-to-end encrypted means your email content is only readable for the email sender and email receiver, others can not know the details, even the service provider.

Actually, most email services are encrypted, but encrypted in the way of clear text, and some email services still do not support end-to-end encryption, which means your email content is readable by those email providers.

3.Phishing Email Attacks

You must have gotten emails like this: the sender pretends to be your contact with a similar name or similar email address. When you click the link or file in the email, it may ask you to enter your account name and password.

This is a wildly used trick to get your private information. Even most people have aware of those tricks now, but there always have new and hard-to-prevent ways to trap you.

4.Accidents In The Sending Process

When you send sensitive data or important files, it may be intercepted by hackers or information read by third parties. Unfortunately, Email can not protect your files from those attacks.

5.Ads From Mail Providers

When you use an email service, you are exposing your private life to the email service provider too. Some providers may access your email contents and analysis your behavior to send targeted advertising.

This is unavoidable because when you use an email service, you must first sign the privacy policy, and the policy on the use of your personal information is there.

How To Keep My Email Secure

For most people, sending and receiving email is inevitable. There are five tips for you to protect your email information secure.

Way 1: Change passwords regularly

Please set a unique and complex password for your email. This is the easiest way, but people rarely do it. A simple password plus your birthday and your name are easy to guess, and if you use the same password for all services, it's high risk when someone gets one service password and tries it in your mailbox.

Way 2: Use a file encryption program

You can use encryption programs for important files. Even if your email is hacked, no one else can get your file contents.

Way 3: Stay alert

Carefully check the email sender before you open the attachment. A phishing email can be sent in various ways, and the best way to prevent it is to stay alert when email content is about your private information, especially when require you to enter a password or tp open a link.

Way 4: Choose a secure email service provider

A reliable service provider can protect your privacy in many ways, they will use many methods to make sure the security of its platform.

Way 5: Avoid using public WiFi

When working in public places, try to avoid using WiFi, even if it's free. Hackers can log into the same free WiFi and try to access your device to compromise your email system.
