The global certificate authority (CA) market size was estimated at USD 173.1 million in 2023 and is projected to reach USD 401.4 million by 2030, growing at a CAGR of 13.1% from 2024 to 2030. The rapid expansion of this market is closely linked to the increasing reliance on digital transactions, secure communication channels, and the growing need for robust data protection mechanisms.

As the digital economy expands, industries such as e-commerce, online banking, healthcare, and cloud-based services have witnessed exponential growth. This has, in turn, heightened the need for security solutions that ensure the integrity, confidentiality, and authenticity of online interactions. Certificate authorities play a crucial role in this ecosystem by issuing digital certificates that validate identities and enable secure communications over the internet. These certificates help protect users and organizations against a wide range of cybersecurity threats, including phishing attacks, man-in-the-middle (MITM) attacks, and data breaches.

The surge in global internet usage further underscores the rising demand for CA services. According to Atlas VPN, the number of internet users worldwide is expected to exceed 6 billion within the next five years. In 2023, approximately 5.16 billion people were connected to the internet, representing 64.4% of the global population. By 2028, this figure is projected to increase by nearly 19%, reaching 6.13 billion users. This significant rise in digital connectivity translates directly into greater online activity, including e-commerce transactions, digital banking, and enterprise collaboration all of which require trusted digital certificates to safeguard sensitive data and ensure secure digital identities.

Key Market Trends & Insights:

  • Regional Insights: North America dominated the global certificate authority market in 2023, accounting for the largest revenue share of 33.7%.
