What is the Market Size of Email Encryption, and Why is it Important for Securing Email Communications?

Email accounts are susceptible to compromise through phishing attacks or other approaches, leaving your email communications exposed to cybercriminals. Throughout transit over the email network, messages and attachments can be intercepted. Emails lack encryption by default as they travel through your servers of email to the recipient, which implies that if hackers attain admittance to this data, they can read your emails and their attachments.

Encryption plays an important role in preventing emails. When emails are encrypted, their contents are scrambled, confirming that only the designated recipient can admittance them. This article will delve into the market size, email encryption work, and importance of encryption, and the benefits of email encryption.

Email Encryption

Email Encryption involves concealing the content within an email message to prevent unauthorized admittance or alterations. This procedure entails encoding the content using a cryptographic key, essentially transforming readable text into indecipherable combinations of randomized characters. By employing a key, the recipient’s email provider can decode the encrypted text, unveiling the content of the email message securely once it has been successfully carried to the intended inbox.

Different email providers use encryption to safely transmit messages between the sender and recipient’s email servers. This practice assists in preventing attackers from intercepting emails throughout transit, thereby preventing their ability to view, alter, or steal sensitive information comprised in those messages. In addition, some email services may lack encryption, growing users’ vulnerability to data theft and other potential assaults.

Market Size

According to GMI Research, the email encryption market size and growth are predicted to rise at a CAGR of 20.2% in the forecast period in the period of 2022-2029 due to significant growth in the implementation of Bring Your Own Device trend by firms, and vigorous regulatory framework.

How does the email encryption work?

Data encryption can be succeeded through symmetric or asymmetric encryption algorithms. Symmetric encryption engages the same secret key for both encryption and decryption techniques. On the other hand, asymmetric or public key cryptography uses a public key for encryption and a corresponding private key for decryption, developing the security of the communication procedure.

Whereas, employing symmetric cryptography for email encryption is practical but poses a challenge: securely sharing the secret key with the proposed recipient. If this key is sent via email, the email must be unencrypted for the recipient to read it. Unfortunately, this opens the prospect for an eavesdropper to interrupt the email and use the enclosed key to decrypt the encrypted email, compromising its safety.

Due to the difficulties caused by symmetric cryptography, many email encryption schemes opt for asymmetric cryptographic algorithms. In asymmetric cryptography, the key utilized for encryption is public, enabling it to be sent over insecure email or posted on a website without compromising security. This method develops the convenience and security of sharing encryption keys in email communication.

Using a user’s public key enables the creation of an encrypted email that remains unreadable to eavesdroppers. Upon the intended recipient receiving the email, they decrypt it utilizing the corresponding private key, discovering the original message. This asymmetric encryption procedure confirms secure communication by enabling only the designated recipient to decipher the encrypted content.

Importance of Email Encryption

Emails serve as a prevalent communication medium in businesses, yet they come with inherent risks connected to networks, functioning systems, human vulnerabilities, and procedures. Given that emails regularly comprise sensitive business data or personally identifiable information, they become potential targets for hackers or spammers. The critical threat of unauthorized admittance to this data underscores the significance of email encryption, making it a crucial measure when transmitting sensitive information via email.

Benefits of Email Encryption

While emails contribute significantly to business functions, they concurrently pose substantial risks in the absence of robust data security measures. Email encryption serves as an important solution for organizations to guarantee the highest level of data security. Here are a few benefits of email encryption:

• • Confidentiality and Security: Encryption plays an important role in preventing data integrity in its journey- from the moment it is sent until it is received. End-to-end email encryption delivers protection against data theft, even when the data is at rest. Only recipients possessing the private key necessary for decryption can read the message, confirming a preventive and confidential communication channel. 
• • Authentication: Both symmetric and asymmetric encryptions share the commonality of demanding a key for email decryption, confirming that only authorized users can admittance and read the content. This authentication procedure efficiently bars unauthorized personnel from viewing sensitive information, reinforcing the security and confidentiality of the communicated data. 
• • Regulatory Accordance: Given the prevalent threats and risks in today’s world, regulatory authorities such as GDPR, HIPAA, and others, mandate the encryption of data. Consequently, most email providers align with these demands and offer different email encryption approaches to confirm compliance and develop the complete security of transmitted data.
