Gmail is one of the most popular services today. According to recent studies, Google's email client is used by 1.8 billion people worldwide. That number is increasing the likelihood of a cyberattack on your account. In 2021, Google blocked more than 100 million phishing and data breach attempts. But intruders won’t stop there, so it’s very important to ask these security questions: why should I encrypt emails sent from Gmail? How to securely send files via Gmail? And last but not least, why choose the Sealit Add-on? Hold tight as we answer that.


Gmail Encryption TLS, S/MIME and Confidential Mode

Google relies on the encryption protocol that is called TLS (Transport Layer Security). How does the TLS encryption work? When you send your desired message, your browser will automatically contact Google’s server to secure the connection. Your content is then encrypted and decrypted several times until it reaches the desired destination. The red lock icon is an indication that the message isn’t secured for TLS, while the blue lock icon signifies a secured connection. Nowadays more and more email providers are adopting the TLS industry standard. However, there is a glitch to it – this method only operates if an encrypted message is sent to a Gmail address, and you can’t encrypt mailbox to mailbox.

 


Gmail and S/MIME


Gmail supports another proactive standard that is called S/MIME—or Secure/Multipurpose Internet Mail Extension. S/MIME (SMIME) is a type of end-to-end encryption solution that uses asymmetric cryptography to protect the correspondence between sender and recipient. That means that you have two keys – a public key to encrypt email and a private key to decrypt messages.

 

While the S/MIME standard has a good reputation in data and email protection, it also has certain flaws which must be highlighted. This encryption method is only able to function properly if both the sender and recipient have previously exchanged the keys in advance, meaning that both parties will have to use a service that supports the S/MIME standard. Furthermore, this Gmail extension doesn’t keep the encrypted email secured once it reaches its destination—Google still has all the rights to automatically scan the messages within Gmail. 

 

Confidential Mode Secure or not?


In response to ever-growing and worrying data security trends, Gmail had to introduce a new set of tools and features to protect the email accounts. So, in 2018, Google invented the Confidential Mode, with the initial purpose of adding an extra layer to the company's privacy policy. With that new anti-cybercrime measure came many questions about whether Confidential Mode was truly a security measure that we all needed. But first, let’s say something more about the Confidential Mode itself. With this feature, you can protect sensitive information from unauthorized or accidental sharing. Also, you can set a message expiration date, turn the mode on or off, revoke message access, and require a verification code by text to open messages.

On the downside:

-Google and other email service providers will still be able to see and even store your messages.

-If you set the expiration date, your content would stay in the Sent Gmail folder anyway. 

 

Why you should use Sealit Add- on?


As pointed out above, there is a certain assurance that Google is working on ways to keep your email accounts secure, but as we see, there are also many flaws to it. While the statements of intent were already issued by the company, Google still hadn
’t managed to go into a full end-to-end encryption mode. So, if you're looking for a high-end solution that adheres to the most relevant privacy policies, you should choose Sealit to be your defense tool against any potential threat.

Email encryption isn’t just a mechanism that secures your sensitive information; it’s a standard that every organization should be part of – no matter what kind of operating systems or email services you use.

 

Although we are witnessing a steady rise in email encryption options, the quantity does not always equal the quality of products.
