Public Key Infrastructure Market Report 2026

The public key infrastructure market size has grown exponentially in recent years. It will grow from $5.5 billion in 2025 to $6.65 billion in 2026 at a compound annual growth rate (CAGR) of 20.8%. The growth in the historic period can be attributed to increasing incidents of cyber fraud and data breaches, rising adoption of digital certificates for secure transactions, expansion of e-commerce and online banking, growing regulatory compliance requirements, increased deployment of encryption technologies.

The public key infrastructure market size is expected to see rapid growth in the next few years. It will grow to $13.64 billion in 2030 at a compound annual growth rate (CAGR) of 19.7%. The growth in the forecast period can be attributed to increasing demand for post-quantum cryptography readiness, rising adoption of cloud-native security platforms, expansion of digital identity management systems, growing focus on automated certificate lifecycle management, increasing integration of pki with emerging digital services. Major trends in the forecast period include increasing adoption of cloud-based pki solutions, rising demand for strong authentication mechanisms, growing integration of pki with iot security frameworks, expansion of managed pki services, enhanced focus on zero-trust security architectures.

The increase in the number of cyber frauds is driving the demand for the public key infrastructure market, going forward. Cyber frauds refer to intentional tampering with another person's online-stored personal and financial information. A public key infrastructure functions as a cybersecurity technological infrastructure that combines an HSM (hardware security module) for key storage and protection, a Root CA or Certification Authority for the issue of digital certificates, and public key cryptographic keys to encrypt data and protect from cyber fraud. For instance, in March 2024, according to the Federal Bureau of Investigation's Internet Crime Complaint Center (IC3), a US-based government agency that serves as the central hub for reporting cybercrime to the FBI, ransomware incidents rose from 2,385 complaints in 2022 to 2,825 complaints in 2023, representing an 18% increase. Therefore, the increase in the number of cyber frauds will drive the growth of the public key infrastructure market.

Key companies in the public key infrastructure sector are prioritizing technological advancements, such as offering public key infrastructure (PKI) as a service to maintain their market position. PKI as a Service is a cloud-based service model that provides organizations with the necessary infrastructure and tools to implement and manage a PKI system without the need to construct and maintain the infrastructure themselves. For instance, in November 2023, Microsoft, a US-based technology firm, introduced Microsoft Cloud PKI as part of the Microsoft Intune Suite. This solution automates the processes of certificate issuance, renewal, and revocation, thereby simplifying the typically complex management of a Public Key Infrastructure (PKI). Organizations can establish a cloud-based PKI environment in minutes rather than weeks, eliminating the requirement for extensive planning and on-premises infrastructure. The solution supports certificate-based authentication for various applications, such as Wi-Fi and VPN access, enhancing security and facilitating a transition toward passwordless environments. Microsoft Cloud PKI also includes a registration authority that automatically deploys certificates to Intune-managed devices across multiple platforms, including Windows, iOS, Android, and macOS.

In February 2023, Phenna Group, a US-based provider of testing, inspection, certification, and compliance services, acquired PKI Solutions for an undisclosed amount. This acquisition strengthens Phenna Group's cybersecurity portfolio by incorporating PKI Solutions, which specializes in public key infrastructure (PKI) products and services. This move aligns with Phenna's objective to offer comprehensive cybersecurity solutions. PKI Solutions is a US-based cybersecurity specialist providing public key infrastructure (PKI) products.

Tariffs are impacting the public key infrastructure market by increasing costs of imported hardware security modules, cryptographic processors, secure chips, and specialized networking equipment. Enterprises and government agencies in North America and Europe are most affected due to reliance on imported security hardware, while Asia-Pacific faces cost pressure on PKI hardware exports. These tariffs are increasing deployment costs and extending security upgrade cycles. However, they are also encouraging localized manufacturing of cryptographic hardware, increased adoption of cloud-based PKI services, and innovation in software-centric security solutions that reduce hardware dependence.

Public Key Infrastructure (PKI) constitutes a comprehensive system comprising hardware, software, personnel, guidelines, and policies essential for issuing, managing, distributing, and revoking digital certificates. This framework is pivotal in digital signature protocols and data encryption techniques, contributing significantly to establishing identities for individuals, objects, and services. PKI plays a crucial role in regulated access to systems, resource protection, data security, and ensuring transaction accountability.

Within the structure of Public Key Infrastructure, the primary components encompass hardware modules, solutions, and services. These hardware modules serve as secure network computers, operating either virtually or in the cloud, specifically designed to house the cryptographic operations essential for PKI security. Their primary function lies in safeguarding cryptographic keys, offering deployment modes such as cloud-based or on-premise solutions. These deployment options cater to diverse organizational needs, serving large enterprises, small and medium enterprises (SMEs), and various industries including banking, financial services, insurance, government, defense, IT, telecom, retail, healthcare, manufacturing, and other verticals.

The public key infrastructure market consists of revenues earned by entities by providing public key, private key, certificate authority, certificate store, and certificate revocation list services. The market value includes the value of related goods sold by the service provider or included within the service offering. The public key infrastructure market also includes sales of public key infrastructure hardware components required to create, manage, distribute, use, store, and revoke digital certificates and public-keys. Values in this market are ‘factory gate’ values, that is the value of goods sold by the manufacturers or creators of the goods, whether to other entities (including downstream manufacturers, wholesalers, distributors and retailers) or directly to end customers. The value of goods in this market includes related services sold by the creators of the goods.

The market value is defined as the revenues that enterprises gain from the sale of goods and/or services within the specified market and geography through sales, grants, or donations in terms of the currency (in USD unless otherwise specified).
