Increase in Remote Work and Cloud-Based Email Systems Drives Market Growth

The rise of remote working and cloud-based email platforms has introduced new vulnerabilities in email communications. As businesses increasingly rely on cloud-based systems such as Microsoft 365, Google Workspace, and Zoho Mail to facilitate collaboration, the rapid adoption of these platforms has expanded the potential attack surface for email-related cyber threats.

The number of users on cloud-based email platforms is projected to grow by 30% annually, reflecting a significant rise in cloud adoption, according to Gartner. The shift toward remote and hybrid work models, which accelerated during the COVID-19 pandemic, has amplified the need for secure email access from a variety of devices and locations. As employees access email systems on smartphones, laptops, and tablets, the risk of malware exposure increases.

• PwC reports that 83% of companies plan to continue offering remote work at least one day a week, emphasizing the need for secure email systems. Cloud-based email systems offer scalability and flexibility, but also present unique security challenges. Microsoft reported that more than 500 million users were on Microsoft 365 by 2025, underscoring the platform's growing reliance on daily business operations.

As cloud-based email adoption increases, businesses are turning to Email Security as a Service (ESaaS) providers for scalable, on-demand protection, particularly for remote teams.

MARKET RESTRAINTS

High Deployment Costs and Low Awareness among SMEs May Hinder Market Adoption

Many Small and Medium-sized Enterprises (SMEs) face challenges in adopting advanced email security solutions due to limited budgets, small IT teams, and low awareness of complex email-based threats. While large enterprises can invest in advanced security tools such as AI-driven phishing protection, encryption, and threat intelligence, SMEs often rely on basic email filters or the default security offered by cloud platforms.

The cost of advanced solutions can be a significant barrier for SMEs, as they often include subscription fees, integration costs, employee training, and ongoing monitoring. This increases the total cost of ownership, delaying adoption, especially when cybersecurity is not witnessed as a core business investment.

• According to Fortinet's 2025 Cybersecurity Skills Gap report, 56% of breaches were linked to a lack of security awareness, and 54% were due to insufficient IT security skills, indicating that limited resources continue to hinder protection levels.

Low awareness of email-based risks further impedes market growth. Many SMEs underestimate threats such as phishing, ransomware, and BEC. Despite understanding these risks, many businesses are reluctant to invest in advanced tools due to budget constraints or a lack of expertise.

Overall, high deployment costs and limited awareness slow the adoption of advanced email security solutions, particularly among SMEs in emerging markets with limited cybersecurity resources.

MARKET OPPORTUNITIES

Growing Demand for AI-Powered Email Threat Detection to Create New Market Opportunities

Cyber attackers are increasingly using AI to create more convincing phishing emails, impersonation messages, and BEC attempts, which traditional rule-based filters often struggle to detect. AI-powered email security solutions can identify suspicious patterns, abnormal sender behavior, malicious links, and spoofed domains in real-time.

This creates opportunities for vendors offering behavioral analytics, natural language processing, automated phishing triage, and adaptive threat intelligence.

• According to Microsoft’s 2025 Digital Defense Report, AI is shaping both cyberattacks and defenses, driving the need for AI-powered protection tools.
• The rise in AI-assisted phishing, as reported by KnowBe4’s 2025 phishing report, with 82.6% of phishing emails using AI, further opens the market for AI-based detection. Additionally, BEC remains a major area for AI detection, with BEC accounting for USD 2.77 billion in losses in 2024.

The growing use of AI by cybercriminals is driving enterprises to adopt smarter, AI-driven email security platforms, creating a significant market opportunity for vendors in this space.
