The public key infrastructure market size has grown exponentially in recent years. It will grow from $4.6 billion in 2024 to $5.54 billion in 2025 at a compound annual growth rate (CAGR) of 20.7%. The growth in the historic period can be attributed to security concerns, regulatory compliance, digital transformation initiatives, e-commerce growth, increasing interconnectedness.

The public key infrastructure market size is expected to see exponential growth in the next few years. It will grow to $11.74 billion in 2029 at a compound annual growth rate (CAGR) of 20.6%. The growth in the forecast period can be attributed to IoT proliferation, blockchain integration, quantum-safe cryptography, rapid digitalization, focus on user privacy. Major trends in the forecast period include blockchain integration for certificate transparency, shift towards managed PKI services, implementation of zero trust security frameworks, enhanced certificate lifecycle management, regulatory compliance requirements.

The rise in cyber fraud incidents is driving the demand for the public key infrastructure (PKI) market. Cyber fraud involves the intentional tampering with an individual's online-stored personal and financial information. A public key infrastructure serves as a cybersecurity framework that integrates a hardware security module (HSM) for key storage and protection, a Root Certificate Authority (CA) for issuing digital certificates, and public key cryptographic keys to encrypt data and safeguard against cyber fraud. For example, in March 2023, the Internet Crime Report 2021 published by the Federal Bureau of Investigation (FBI), a US-based domestic intelligence and security agency, revealed that in 2022, investment scams were the costliest schemes reported to the Internet Crime Complaint Center (IC3). Complaints regarding investment fraud surged from $1.45 billion in 2021 to $3.31 billion in 2022, reflecting a 127% increase. Within these complaints, cryptocurrency investment fraud escalated from $907 million in 2021 to $2.57 billion in 2022, marking an increase of 183%. Thus, the growing incidence of cyber fraud is expected to drive the expansion of the public key infrastructure market.

The increasing accessibility and widespread use of mobile devices are projected to contribute to the growth of the public key infrastructure market. Mobile devices are portable electronic devices designed for wireless communication and on-the-go usage. These devices frequently handle sensitive information, including personal messages, emails, and financial transactions. PKI offers a secure framework for encrypting and decrypting data, ensuring that communication remains confidential and secure. For instance, in 2022, according to Oberlo, a Lithuania-based cloud-based drop-shipping solution provider for online retailers, the number of global smartphone users was estimated to be 6.6 billion, reflecting a 4.9% annual increase from 2021. Additionally, in January 2022, Zippia, a US-based online recruitment services company, reported that there would be 294.15 million smartphone users in the United States, with nearly 85% of American adults expected to use smartphones. Therefore, the growing availability and widespread use of mobile devices are anticipated to drive demand for the public key infrastructure market.

Technological advancement is a significant trend gaining traction in the public key infrastructure (PKI) market. Major players in this field are concentrating on technological improvements to maintain their competitive edge. For example, in September 2024, the Ethiopian government launched a Public Key Infrastructure (PKI) facility aimed at enhancing the data exchange aspect of the country's digital public infrastructure (DPI). This PKI allows for reliable and secure digital data exchange by employing encryption methods that safeguard information during transmission. The PKI encompasses hardware, software, professionals, and a legal framework, establishing a robust ecosystem for managing digital certificates and ensuring secure communications.

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.

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.
