The email security market was evaluated at US$3,976.114 million in 2021 and will grow at a CAGR of 17.01% to be worth US$11,941.054 million by 2028.

Email security refers to the methodologies and tools used to safeguard email communications and accounts against unauthorized intrusion, potential loss, or compromise. Organizations can bolster their stance on email security to counteract malicious threats, which can range from malware and spam to phishing attacks. BFSI, government, healthcare, and information technology & telecommunications sectors, among others, represent a diverse spectrum of end users served by the email security industry. The email security market is primarily driven by the escalating frequency of cyber-attacks and an increasing emphasis on preventing data leakage

Growing focus on data loss prevention bolsters the email security market growth.

Email security plays a critical role in Data Leakage Prevention (DLP) as it aids in safeguarding sensitive information from unauthorized transmission through emails, a common and often overlooked channel for data leaks Government bodies globally are implementing stringent data protection laws and regulations to ensure the confidentiality and integrity of sensitive data. For instance, according to the Ministry of Electronics & IT, in June 2023, the Indian Computer Emergency Response Team (CERT-In) published a set of guidelines outlining best practices concerning the appropriate usage and management of information security practices.

Increasing phishing attacks drive the email security market expansion.

Phishing attacks pose a considerable threat to both businesses and individual users, particularly in sectors like retail where vast amounts of sensitive data are handled. These deceptive attacks involve seemingly legitimate emails that attempt to deceive recipients into revealing confidential information such as passwords or credit card numbers. The rising prevalence of such threats has amplified the need for robust email security solutions. According to the Anti-Phishing Working Group (APWG) report, in the second quarter of 2022, the APWG reported a total of 1,097,811 phishing attacks globally, marking a significant surge of 246% compared to the 316,747 attacks observed in December 2021.

Technological advancement in email security drives market growth.

The email security industry growth is significantly propelled by advancements in email security solutions, particularly the integration of Artificial Intelligence (AI) and machine learning (ML). By leveraging AI and ML technologies, email security systems can dynamically adapt and evolve to detect sophisticated cyber threats such as phishing, and malware, thereby driving the adoption of cutting-edge email security solutions. For instance, in February 2023, SlashNext unveiled Generative HumanAI which is the first in the industry to leverage generative artificial intelligence technology to counteract advanced cyber threats such as business email compromise (BEC), supply chain attacks, executive impersonation, financial fraud.

North America is projected to dominate the email security market.

North America will be the dominant player in the market due to the significant investments and acquisitions in email security by major companies. For instance, in February 2022, Cloudflare acquired Area 1 Security, for approximately $162 million, which will enable Cloudflare to augment its zero-trust offerings by incorporating a well-established email security product. Additionally, in March 2021, Hornetsecurity acquired Canada-based Zerospam and such a strategic acquisition enabled Hornetsecurity to extend its footprint in the North American market. Growing cyber-attack prevalence is further booming the email security market demand. According to the Microsoft Digital Defense Report, in 2022, out of all the DDoS attacks detected within the past year, 54% were targeted against entities in the United States. Also,

Technological advancements restrain the email security market growth.

Advanced email security solutions, especially those harnessing the capabilities of Artificial Intelligence (AI) and Machine Learning (ML), carry substantial costs that can pose significant challenges for small and medium-sized businesses. These sophisticated technologies, though highly effective in mitigating email threats, often come with a high price tag which can be prohibitive for smaller organizations. For instance, a small enterprise with fewer than 500 employees might typically face configuration fees for email security in the range of $100 to $500, representing a potentially hefty financial burden. Thus, the high cost of adopting and implementing advanced email security solutions, despite their demonstrated effectiveness, can be a notable deterrent for smaller businesses with limited resources.
