The global secure email gateway market is expected to post a CAGR of over 14% during the period 2019-2023, according to the latest market research report by Technavio.
A key factor driving the growth of the market is data loss prevention capabilities. Many email gateway solutions help in DLP. DLP is extremely critical in a corporate environment as it helps prevent the leakage of sensitive information from the corporate network.
The DLP component of an SEG uses business rules to classify and protect confidential information to ensure that unauthorized users do not share data, which can be a threat to the organization. For example, CipherMail offers a DLP solution that is integrated with its CipherMail Email Encryption Gateway.
The DLP solution monitors and filters the email body content; and also allows users to specify keywords and sentences that an outgoing mail should not contain. In times of rule violations, an email can be blocked, or the tool offers an option to notify a manager. These preventive features are expected to expand the market growth in the future.
As per Technavio, the increase in spear phishing will have a positive impact on the market and contribute to its growth significantly over the forecast period.
Global secure email gateway market: Increase in spear phishing
The duration of the spear phishing attacks can vary. Some may last for a day or a week, and some can last for more than a year which is known as a drip campaign.
For instance, Proofpoint’s Advanced Email Security solution uses advanced anomaly detection methods to protect against spear phishing attacks. The Advanced Email Security solution provides sandboxing at the time of delivery of the email, which results in a higher detection of these threats.
The threats can be nullified by the system before a user opens the mail. With the rise in spear phishing attacks, the adoption of secure email gateway solutions is increasing rapidly.
“Apart from data loss prevention capabilities, email gateway solutions help organizations in achieving and maintaining data compliance. Email archiving is one of the key features provided by an email gateway. The email archiving functionality helps in storing emails for legal and compliance requirements.
“Email encryption is another important feature of the secure email gateway. Encryption helps in protecting the sensitive data sent over the email. Such solutions help maintain data compliance, thereby driving the market,” says a senior analyst at Technavio.
