Email Security Market - Global Industry Size, Share, Trends, Opportunity, and Forecast, 2021-2031

The Global Email Security Market is projected to expand from USD 7.16 Billion in 2025 to USD 13.94 Billion by 2031, achieving a CAGR of 11.74%. Email security is defined as the comprehensive set of software, protocols, and measures implemented to shield email accounts and communications against unauthorized access, loss, or compromise. The primary force behind this market's growth is the rising frequency of cyber threats, specifically phishing and business email compromise, which demand robust defense mechanisms to protect sensitive corporate information. Additionally, strict regulatory mandates concerning data privacy are forcing organizations to invest in advanced protection suites. Highlighting this critical need, the Anti-Phishing Working Group reported that the volume of observed phishing attacks hit 989,123 in the fourth quarter of 2024 alone.

Despite the urgent requirement for these solutions, the market encounters significant obstacles related to the high cost and complexity of integrating thorough security layers into existing infrastructures. Small and medium-sized enterprises frequently struggle with the financial demands of premium security platforms and lack the technical expertise needed to manage them effectively. This operational barrier often results in adoption gaps, leaving smaller entities exposed to attacks and hindering the market's broader expansion across businesses of all sizes.

Market Drivers

The increasing frequency and sophistication of email-based cyber threats serve as the main catalyst for market growth, forcing organizations to strengthen their defense perimeters. Cybercriminals are increasingly bypassing legacy filters by employing advanced tactics, such as quishing and multi-stage payload attacks, which necessitate the deployment of responsive, integrated security layers. This surge in threat volume compels enterprises to transition from basic compliance tools to dynamic platforms capable of detecting zero-day anomalies and neutralizing credential theft attempts in real time. For instance, SlashNext's "2024 Phishing Intelligence Report" from December 2024 noted a 703% increase in credential phishing attacks during the second half of the year, largely fueled by the widespread availability of automated phishing kits on the dark web.

Furthermore, the integration of Artificial Intelligence and Machine Learning into threat detection is transforming the sector as a critical response to the weaponization of generative AI by cybercriminals. Security vendors are embedding large language models into their solutions to analyze communication patterns and identify subtle indicators of compromise, such as linguistic irregularities in business email compromise attempts, which rule-based systems often miss.

This technological advancement is essential for differentiating between legitimate correspondence and AI-enhanced social engineering campaigns. According to Darktrace's "Annual Threat Report 2024" published in February 2025, 32% of detected phishing attacks utilized novel social engineering techniques, including AI-generated text with high linguistic complexity. The financial stakes driving this adoption are immense, with the FBI reporting in April 2025 that cybercrime losses exceeded $16 billion in the previous year.

Market Challenges

The substantial capital investment and technical complexity required to implement comprehensive email defense systems represent a primary impediment to the broader expansion of the Global Email Security Market. While large enterprises typically possess the necessary resources, Small and Medium-sized Enterprises frequently face prohibitive barriers to entry due to the high costs associated with premium security suites. This financial strain is compounded by a shortage of specialized IT personnel capable of managing intricate security configurations, forcing smaller entities to forgo advanced protections. Consequently, the inability to secure affordable and manageable solutions limits market penetration in the SME sector, effectively capping the total addressable market and slowing overall revenue growth.

This financial friction is supported by recent data highlighting the disparity between security requirements and available resources. According to ISACA, 51% of organizations reported in 2024 that their cybersecurity budgets were underfunded. This statistic indicates that a majority of potential buyers are operationally restricted from acquiring necessary defense mechanisms. When organizations are unable to allocate sufficient funds, the adoption rate of essential email security platforms inevitably declines, directly hampering the commercial progress of the market.

Market Trends

The transition from Secure Email Gateways (SEG) to API-Based Deployment Models marks a fundamental architectural evolution in the Global Email Security Market, driven by the inability of perimeter-based defenses to inspect internal traffic or effectively counter business email compromise. Unlike legacy gateways that require MX record changes, API-based Integrated Cloud Email Security (ICES) solutions connect directly into cloud productivity suites, allowing for the analysis of historical communication patterns and the detection of lateral movement. This shift is accelerating as organizations prioritize behavioral analysis over static signature detection to identify sophisticated threats that evade traditional filters. The urgency for this architectural upgrade is evidenced by the rising volume of complex attacks; according to Abnormal Security's January 2025 report, the median monthly rate of advanced email attacks in the APAC region surged by 26.9% year-over-year, highlighting the critical need for internal, API-driven visibility.

Simultaneously, the Rise of Automated Post-Delivery Incident Response and Remediation is becoming a standard operational requirement to address the latency gap between threat delivery and detection. As phishing campaigns operate at machine speed, manual analysis by security operations centers is increasingly insufficient, prompting the adoption of Mail Security Orchestration, Automation, and Response (M-SOAR) capabilities. These systems automatically retract malicious messages from user inboxes after delivery and correlate threat intelligence across endpoints, significantly reducing the dwell time of successful breaches. The efficacy of these automated mechanisms is growing rapidly; Cloudflare reported in March 2025 that their automated systems resolved 78% of phishing reports in the second half of 2024 without human intervention, demonstrating the market's pivot toward autonomous defense operations.
