Email Encryption Market 2024–2030: Rising Cyber Threats Propel Security Adoption Across BFSI & Enterprise Sectors
The global Email Encryption Market, valued at USD 6.3 billion in 2023, is projected to expand to USD 24.34 billion by 2030, registering an impressive CAGR of 21.3% during the forecast period. This rapid growth is driven by escalating cybersecurity threats, stringent data protection regulations, the rise of cloud-based email platforms, and increasing enterprise focus on secure communication.
As email remains the primary communication channel for businesses worldwide, the need to protect sensitive corporate and customer information has become essential. Email encryption technologies ensure that only authorized users can access email content, preventing data breaches, unauthorized access, and cyberattacks.
Market Overview
Email encryption involves converting email content into unreadable text using cryptographic algorithms. Only the intended recipient can decrypt and read the message. This prevents cybercriminals, unauthorized users, and malicious actors from intercepting or exploiting sensitive data.
Industries such as BFSI, healthcare, government, legal services, IT & telecom, retail, and manufacturing increasingly rely on email encryption to protect personal, financial, and confidential business data.
The rise of phishing, ransomware, business email compromise (BEC), and identity theft has further accelerated the adoption of end-to-end and gateway email encryption solutions.

Market Dynamics
- Key Growth Drivers
- Surge in Cyberattacks and Data Breaches
Cyberattacks targeting email systems are increasing in frequency and sophistication:
- Phishing and spear-phishing
- Ransomware attacks
- Business email compromise (BEC)
- Credential theft
- Malware distribution
Email encryption acts as a secure shield, reducing the chances of unauthorized access or interception.
- Strict Data Protection Regulations
Global regulations mandate secure communication practices:
