The Global Email Encryption Market is expected to witness high growth at a CAGR of 21.70 percent during the 2014-2019 forecast period. Developing regions are experiencing a surge in the number of organizations using emails as a source of communication and transmission of confidential data.
How Email Encryption Works
Email encryption prevents a message from being accessed by anyone but the intended recipient. An unencrypted email sent over a network allows other users in the network to capture the login credentials and the messages sent or received. A public network is the most sensitive and is exposed to high chances of data theft.
PGP is client-side encryption software used to encrypt/decrypt data files, directories, disks, and emails. However, PGP is being replaced by TLS at a fast rate because of the lack of user-friendliness.
TLS is a cryptographic protocol that allows secure transmission of emails between trusted parties without the need of PGP. It helps in automatic encryption and decryption of messages over the network.
Pros and Cons to Email Encryption
Advantages of Email Encryption
- Helps move data to cloud
- Helps achieve multi-tenancy in cloud
- Prevents service providers from accessing any data
- Helps meet the regulations
- Provides a safe harbor from breach notification
- Service providers have a competitive edge
- Provides security to data backups
- Secures remote offices
- Secures outsourcing and licensing
Disadvantages of Email Encryption
- Difficult to remember multiple passwords
- Requires cooperation from end-users for encryption process
- Develops a false sense of security
Increase in Regulatory Compliance for Electronic Communications
Because data privacy is a growing concern, companies have to comply with different regulations such as HIPPA (for the Healthcare sector), GLBA and BASEL II (for the Finance sector), and the PCI-DSS standards and Sarbanes-Oxley (for the Financial sector). Organizations need to comply with these regulations. Non-compliance with regulations may lead to penalties for organizations.
These regulations guarantee that there are detailed plans to ensure that data transmission is done in a safe and secure way. Hence, companies opt for email encryption solutions to control data breaches because of the strict data privacy regulations. The imposition of regulatory compliance is thus supporting the growth of the Global Email Encryption market.
Mobile Devices Supporting Email Encryption
With the increased usage of mobile devices by employees, vendors are expected to release solutions that would support email encryption on cellphones, iPads, and tablets. These solutions allow email encryption and decryption without the need to install any software. This helps to comply with the regulations of partners and customers and reduces the cost of IT administration and the overall cost.
