This post will show you why end-to-end encryption is ideal instead of TLS.
Email communication is a fascinating thing that we all have become used to using hourly. You can attach files, send them to multiple people at once, and design every email with signatures and images.
But nobody necessarily understands or thinks about what is happening behind the scenes when sending an email. We type in our message and recipient and send the email. In the background of every email you send and receive, protocols, certificates, and servers are involved in sending your email messages.
Most email providers are not using the most secure safety measures, which everyone should consider, especially if you send important files via email.
Here's why it's essential to encrypt your emails and ensure you're doing what you should to keep your emails safe and secure.

TLS vs. End-to-End Encryption
First, let's look at what TLS and End-to-End Encryption are:
What is TLS?
In short, TLS (Transport Layer Security) is a protocol to keep communication private and secure over the Internet. It works with regular email communication, as well as messaging and VOIP.
TLS can help protect you from data breaches, which has become very important in today's world, where vital information is sent online, and you are susceptible to hacking attacks.
There is a three-step process for every TLS connection:
- Keeps data hidden from third parties not involved in the communication.
- Makes sure that both parties are who they say they are.
- Ensures that the information is original and has not been changed.
One of the principal vulnerabilities to using a TLS connection is the many touchpoints involved and having a ‘man-in-the-middle' attack through encryption.
What is End-to-End Encryption?
End-to-end encryption is how we keep private online messages, photos, information, and files out of the wrong hands. To date, it is one of the safest ways to keep your online communication private and can be especially important to those who send essential information.
E2EE ensures the entire line of communication is encrypted so nobody can intercept any message or file in sending and receiving.
E2EE can be pretty confusing, but, in short, it goes like this:
- The sender uses the receiver's Public Key to encrypt a message.
- The Sever sees no plain text, only the encrypted message.
- The message can only be opened when the Receiver uses their Private Key (which only they have) to open it.
- The receiver reads the message.
Things are much more complicated when using End-to-End Encryption, but this should give you an idea of how it works on the surface.
Why Use E2EE?
E2EE is built into your hardware and software, meaning it just happens and doesn't involve much work. E2EE keeps your data safe from hacks and keeps everything private.
In a world where vital information is shared online through email and other messaging apps (like Whatsapp and private messaging), E2EE can keep you safe from identity theft and the exposure of files you want to stay secure.
How to Get Your Emails End-to-End Encrypted
Well, the process of End-to-End Encryption is complex and deep, which means you ccan'tdo it yourself. TThat'swhy an email encryption add-in is the way to go right now.
Add-ins like Permido allow you to secure your emails with E2EE and, on top of that, become GDPR-friendly. Permido will enable you to safely use your email with the click of a button, so you ddon'thave to worry about having someone hack your data or read your messages.
With all the complexities around encryption, who would have guessed that you can keep yourself safe by using a simple plug-in?
Why End-to-End Email Encryption Is the Way To Go: FAQs
Why is email encryption necessary?
Traditional email communication is often unencrypted, meaning anyone who intercepts the message can read it. Encryption adds a vital layer of security, especially when dealing with sensitive information.
What does end-to-end encryption mean for email?
With end-to-end encryption, the message is encrypted on the ssender'sdevice and remains encrypted until it reaches the rrecipient'sdevice. The recipient then uses their decryption key to access the message content.
What is the critical advantage of end-to-end efficient encryption?
The critical advantage of end-to-end encryption is that it removes the “rust factor” from email service providers. Even if hackers gain access to the email servers, they cannot decrypt the message content without the rrecipient'skey.
Is it reasonable to have end-to-end encryption?
End-to-end encryption is highly beneficial for anyone who values email privacy and security, especially when dealing with sensitive information. However, iit'simportant to note that some encrypted email services might have limitations, such as difficulty recovering lost passwords or message retrieval on new devices.
How do I get end-to-end encryption for email?
Several email service providers offer end-to-end encryption options. Research and choose a service that aligns with your needs, considering factors like ease of use, security features, reputation, and potential limitations.
Bottom Line
By understanding the importance of end-to-end encryption and addressing these FAQs, you can make informed decisions about securing your email communication and safeguarding your sensitive information.
In ttoday'sdigital landscape, prioritizing email security is essential for protecting your privacy and maintaining control over your data.
