During the past 5 years or so, the bigger certificate authorities-like Let's Encrypt (USA), Sectigo (USA), GoDaddy (USA), etc.-have changed the game by offering free or low-priced DV certificates in very large volumes. This has enabled startups, SMEs, and individual owners of websites to secure their websites quickly and economically. To help with this process more than ever, DTC CA brands have incorporated API's, self-service certificate management platforms, and partnerships with web hosting providers to help improve their service while minimizing overhead. With the growing understanding of cybersecurity threats and the need for encrypting communications, this has dramatically bolstered the demand for DV certificates in developing digital economies like India, Brazil, and Southeast Asia. The SSL certificate market in India witnessed rapid growth in the year 2024, with DV certificates making up over 70% of newly issued certificates due to increased website registration and digital transformation of various sectors. For instance, in March 2025, Cloudflare, Inc., the leading connectivity cloud company, announced that it is expanding end-to-end support for post-quantum cryptography to its Zero Trust Network Access solution. Organizations can securely route communications from web browsers to corporate web applications to gain immediate, end-to-end quantum-safe connectivity. By mid-2025, Cloudflare is going to add support for post-quantum cryptography to all its IP protocols, thereby significantly extending compatibility across most corporate applications and devices.

Based on enterprise size, the certificate authority market is segmented into SMEs and Large Enterprises. In 2024, the Large Enterprises segment dominated the market and is expected to maintain its leading position throughout the forecast period. The sophisticated cyberattack risks have increased, together with stringent regulatory mandates and enterprise-grade encryption protocols. Large organizations heavily invest in Public Key Infrastructure (PKI) solutions. These enterprises generally require multi-domain and wildcard certificates to secure their very vast networks, internal systems, and customer-facing applications. To such requirements come the heavy industry weights like DigiCert (USA), Entrust (USA), and GlobalSign (Japan), offering high-assurance certificates, automated lifecycle management tools, as well as scalable trust services. With increased reliance on cloud platforms and digital identity management, as well as remote work infrastructure among Fortune 500 companies, robust certificate management has become even more significant. For example, in August 2024, Azure Key Vault was infused with a certificate authority feature integrated by Microsoft to automate the certificate issuance and renewal processes for large enterprises in the cloud ecosystem. Again, large-scale enterprises within banking and health care will superintend the evolution of advanced use cases such as mutual TLS authentication for securing APIs, validating IoT devices, and the integration with DevOps, thereby accelerating segmental growth. These sectors continue to lead innovations in securing digital communications and protecting data privacy.

Based on vertical, the certificate authority market is segmented into BFSI, Retail and E-commerce, Government and Defence, Healthcare, IT and Telecom, Travel and Hospitality, Education, and Others. In 2024, the BFSI (Banking, Financial Services, and Insurance) segment dominated the market and is expected to maintain its leading position throughout the forecast period. With financial institutions handling high volumes of sensitive customer data and being constantly under attack from cybercriminals and phishing, the demand for high-assurance certificates-like Extended Validation (EV) and client authentication certificates, skyrocketed. Certificates provide the essential security for online banking portals, mobile applications, internal systems, and frameworks for digital identity. The PKI infrastructure is now widely deployed in BFSI for facilitating digital banking and fintech acceptance. DigiCert, GlobalSign, and Entrust are major players that provide their clients with advanced encryption tools and certificate lifecycle management platforms in strict alignment with global standards such as PCI-DSS, PSD2, and SOC2 compliance.
