E-mail Security Market Overview

Email has long been a target for cybercriminals due to its widespread use in both personal and professional communications. As phishing, malware attacks, and business email compromise (BEC) grow in sophistication, organisations of all sizes are increasingly relying on email security solutions to protect their communications, data, and reputation.

E-mail Security Market Size

The email security market was valued at approximately USD 4.64 billion in 2023. It is projected to grow at a CAGR of 13.20% between 2024 and 2032, reaching a market size of USD 14.12 billion by 2032.

This substantial growth can be attributed to the rising number of cyberattacks, the growing volume of email communication, and the increasing need for data privacy and regulatory compliance. As organisations continue to adopt cloud-based email services and remote work culture, email security has become even more critical.

E-mail Security Market Trends

Rising Sophistication of Cyber Threats: The frequency and complexity of cyber threats, including phishing, ransomware, and business email compromise (BEC), are escalating. As a result, the need for advanced email security solutions is higher than ever.

Cloud-based Email Security Solutions: The shift towards cloud-based email platforms like Microsoft 365, Gmail, and others is driving the demand for cloud-based email security solutions. These solutions are scalable, flexible, and easier to implement across various business models.
