The global COVID-19 pandemic has been unprecedented and staggering, with secure email gateway market experiencing higher-than-anticipated demand across all regions compared to pre-pandemic levels. The sudden rise in CAGR is attributable to the market's growth and demand returning to pre-pandemic levels once the pandemic is over. 

A Secure Email Gateway (SEG) is a cybersecurity solution designed to protect organizations from various email-borne threats, such as phishing attacks, malware, spam, and other types of malicious content. It acts as an intermediary between an organization's email system and the external email servers, providing an additional layer of security and filtering to ensure that only safe and legitimate emails reach the end-users' inboxes.

The market for secure email gateways was growing steadily due to the increasing reliance on email for business communication and the rising number of cyber threats targeting email systems. Companies of all sizes and industries were recognizing the importance of implementing robust email security measures to safeguard sensitive data, intellectual property, and maintain business continuity.

KEY FINDINGS

COVID-19 IMPACT

 Pandemic Increased the Demand for Market

With a shift to remote work arrangements during the pandemic, the reliance on digital communication, including email, increased. This may have prompted organizations to invest more in email gateway solutions to protect their remote workforce from phishing attacks, malware, and other cyber threats.  The pandemic brought about a surge in cyber threats, with hackers taking advantage of the confusion and uncertainty surrounding the global crisis. Secure Email Gateways became crucial in detecting and blocking COVID-19 related phishing scams and malicious emails. Many companies prioritized business continuity and data protection during the pandemic. As a result, they may have upgraded or adopted new email gateway solutions to ensure secure communications even during remote operations. The pandemic accelerated the pace of digital transformation in many industries. Organizations that were in the process of transitioning to cloud-based email solutions might have also considered enhancing their security measures through email gateways.

LATEST TRENDS

Data Loss Prevention (DLP) to Fuel Market Growth

DRIVING FACTORS

Rise in Cybersecurity Threats to Drive Market Growth

With the increasing number of cyber threats, including phishing attacks, ransomware, and email-based malware, organizations are becoming more conscious of the need to secure their email communications. Email Gateways play a crucial role in protecting against these threats and safeguarding sensitive information. Various industries are subject to strict data protection regulations, such as GDPR (General Data Protection Regulation) and HIPAA (Health Insurance Portability and Accountability Act). Secure Email Gateways help organizations comply with these regulations by enforcing email security policies and preventing data leaks. Cloud-based email services are becoming increasingly popular due to their flexibility and cost-effectiveness. As organizations transition to cloud-based email platforms like Microsoft 365 and Google Workspace, the need for cloud-based email gateways to protect these services grows as well. The trend of remote work has accelerated in recent times, and it has made organizations more vulnerable to cyber threats. An email gateway ensures that remote employees can communicate securely and prevents cyber attackers from exploiting vulnerabilities associated with remote work setups. All these factors are contributing to secure email gateway market growth.

• According to CISA 2023 Insights, 74% of U.S. organizations reported phishing attempts as the primary catalyst for deploying secure email gateways.

• According to NIST 2023 Data Breach Study, 62% of confirmed breaches involved compromised email accounts.

RESTRAINING FACTORS

Data Privacy and Compliance Concerns to Restrict Market Growth

Email security often involves scanning and analyzing the content of emails, which raises concerns about data privacy and compliance with regulations like GDPR. Organizations had to ensure that their SEG solutions met the necessary data protection standards. Integrating SEG solutions into existing email infrastructures could be complex and time-consuming, especially for large organizations with multiple email systems or cloud-based email providers.

• According to Cloud Security Alliance 2023 Survey, 49% of SMEs cite integration complexity with legacy mail systems as a deployment barrier.

• According to ENISA 2024 Threat Landscape Report, 38% of organizations report insufficient skilled security staff delaying gateway roll-out.
