Email encryption refers to disguising and obfuscating the contents of an email to prevent interception by a third party. It ensures that the information contained within the email is read by the intended recipient only. Email encryption involves the encryption of connection from the email service provider and the encryption of sent, received, and stored emails.
Email encryption typically requires a secure, two-factor authentication for accessing emails. SSL, TLS, and STARTTLS have commonly used email encryption protocols. With the growth of cloud email services and the rising frequency of phishing attacks, the adoption of email encryption has increased.
Email Encryption Market Trends
The email encryption demand is mainly driven by the increasing frequency of email phishing attacks. The operational drawbacks of email encryption are a key factor in limiting the growth of this market.
The increasing frequency of email phishing attacks
In recent years, the growth of digitization and the proliferation of cheaper internet services have increased. Almost all major functions of everyday life such as banking, grocery shopping, entertainment, and communication can be carried out online. In the modern age, an email address is virtually as important as a physical address since an email address is a basic requirement for online interaction. More and more official and important data, transactions, and communications are being carried out using emails.
The growth of email has led to a corresponding rise in email phishing. Due to the interconnected nature of digital systems, phishing attacks result in massive data breaches, identity theft, and financial losses. As more and more of the global population goes online, the intensity of phishing attacks has been increasing in recent years. Proofpoint, Inc., a cybersecurity services company, conducted a study in 2020 that estimates that more than 83% of business organizations globally have experienced an email phishing attack. Business organizations implement security measures such as email encryption in response to growing phishing attacks. It is a major driver of the growth of the global market.
Operational drawbacks of email encryption services
Although using email encryption services drastically reduces the likelihood and impact of a cyberattack, it still suffers from various operational drawbacks. Cyber threats are evolving in real-time, leaving cybersecurity service providers at a disadvantage. Furthermore, there are always several inherent flaws within the system architecture of email encryption applications.
Cybercriminals use these security flaws to breach email encryption and carry out attacks. Cybersecurity companies provide almost immediate patches and updates to remove vulnerabilities and weaknesses; however, a lot of damage might be done within that timeframe. After sustained efforts, lower-end email encryption applications have weaker algorithms that hackers can crack.
Another major drawback is the human factor. The best email encryption is worthless if the human operator does not exercise basic cybersecurity precautions. Clicking on infected links, opening phishing emails and careless operation of email accounts are some human mistakes that cannot be accounted for by email encryption. Therefore, operational drawbacks of email encryption are a key challenge for the growth of the global market.
Email Encryption Market Segment and Shares
The global email encryption market is segmented into type, component, enterprise, end-user, and region. The email encryption market by end-user is further segmented into BFSI, consumer goods and retail, manufacturing, IT and ITeS, healthcare, transportation, government and military, and others.
BFSI is leading this segmentation since it has become an end-user of email encryption services. Due to the rapid proliferation of online and digital banking services, data security has become paramount. Email phishing can lead to massive financial and data losses for banks and consumers. Therefore, almost all leading global banks have adopted email encryptions for B2B and B2C communication.
Why Email Encryption Market Matters by 2033
