Market Driver

"Cybersecurity and Global Compliance"

The certificate authority market is registering significant growth, driven by rising cybersecurity threats and the growing demand for comprehensive security solutions across regions. Businesses are increasingly prioritizing data protection and trust with customers as cyberattacks become more frequent and sophisticated.

Cyber threats such as data breaches, ransomware, and phishing attacks have heightened the need for robust digital certificates, including SSL/TLS certificates, to ensure secure communication and authentication.

In today's digital landscape, securing websites, online transactions, and sensitive customer data is more critical than ever. SSL/TLS certificates are essential tools for encrypting data and verifying the identity of online entities, offering a trusted and secure way to protect sensitive information during transmission over the internet.

Additionally, as organizations expand their digital presence globally, they face the challenge of adhering to region-specific security regulations and compliance requirements. This has fueled the demand for certificate authority services that can provide scalable, cross-border security solutions.

Businesses require digital certificates, identity management, and encryption solutions that not only ensure secure communication across regions but also comply with local data privacy laws and international standards.

This demand for compliance-driven security solutions is driving the need for certificate authorities to enhance their offerings and provide regionally tailored services to ensure that businesses maintain trust, meet legal obligations, and secure their digital infrastructure globally.

• In April 2024, DigiCert and Deutsche Telekom announced a strategic partnership to enhance digital certificates and identity management offerings. The collaboration aimed to deliver comprehensive security solutions tailored to the diverse needs of European customers, focusing on public key infrastructure, identity and access management, and hardware security solutions for various devices.

Market Challenge

"Complexity of Certificate Lifecycle Management"

A major challenge in the certificate authority market is the increasing complexity of certificate lifecycle management, particularly for large organizations with expansive digital infrastructures. As businesses scale, they often require hundreds or thousands of certificates for various applications, websites, and devices.

Managing these certificates, ensuring timely renewals, and handling updates or revocations can become overwhelming, especially when dealing with large volumes across different platforms. This complexity makes it easier for errors to occur, such as missed renewals or improper revocations, creating security vulnerabilities.

Expired certificates or mismanaged digital certificates can leave critical systems exposed to cyberattacks, posing significant risks to data integrity and trust. Certificate authorities are offering automated certificate management solutions that streamline the lifecycle process.

Automated systems help organizations monitor certificate statuses, schedule renewals, and manage updates or revocations with minimal human intervention.

Market Trend

"Rise of Subscription-based Certificates and Shift Toward Cloud-based Certificate Management"

The certificate authority market is registering key trends that are reshaping the way organizations manage digital certificates and security solutions. One of the key trends is the rise of subscription-based certificate solutions and API integrations.

This shift allows SSL/PKI resellers, domain registrars, web hosts, and Managed Service Providers (MSPs) to automate certificate lifecycle management and domain validation through a single API.

Businesses can eliminate traditional per-certificate costs by moving to a subscription-based model, enabling them to scale their operations more efficiently while streamlining certificate management. This trend is making the process more cost-effective and providing additional benefits like enhanced automation and simplified workflows.

• In February 2025, Sectigo launched Certificates as a Service (CaaS), designed for SSL/PKI resellers, domain registrars, web hosts, and MSPs. The new offering enables partners to automate certificate lifecycle management and domain validation procedures through a single API, while offering a subscription-based pricing model that eliminates traditional per-certificate costs and enhances scalability.

Another trend is the increasing shift toward cloud-based certificate solutions. As organizations continue to embrace cloud technologies, there is a growing demand for scalable, flexible, and cost-effective ways to manage digital certificates.

Cloud-based certificate authorities allow businesses to automate processes, centralize management, and ensure a seamless experience across multiple platforms. This trend not only makes it easier to deploy, monitor, and maintain certificates but also plays a crucial role in driving the growth of cloud-based security solutions in the market.
