What Is Covered Under Public Key Infrastructure Market?

Public key infrastructure is a system that consists of the necessary hardware, software, personnel, guidelines, and policies to issue, manage, distribute, utilize, store, and revoke digital certificates. The public key infrastructure is used in digital signature protocols and/or data encryption techniques. Public key infrastructure aid in establishing the identity of individuals, objects, and services, enabling regulated access to systems and resources, data protection, and transaction accountability. The main components of the public key infrastructure are hardware modules, solutions, and services. A hardware module is a secured network computer that may be utilized virtually or in the cloud and houses the cryptographic operations that public key infrastructure needs to be secure. The hardware module is used or designed to safeguard cryptographic keys. The deployment modes are cloud and on-premise which are used by large enterprises, and small and medium enterprises (SMEs) organizations in banking, financial services and insurance, government, and defense, IT and telecom, retail, healthcare, manufacturing, and other verticals.

What Is The Public Key Infrastructure Market Growth Forecast?

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.

What Is The Driver Of The Public Key Infrastructure Market?

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 industry.

Global Public Key Infrastructure Market Trends and Insights

Major companies operating in the field of public key infrastructure are focusing on technological advancements, such as public key infrastructure (PKI) as a service, to sustain their market position. Public Key Infrastructure (PKI) as a Service refers to a cloud-based service model that provides organizations with the infrastructure and tools needed to implement and manage a PKI system without having to build and maintain the infrastructure themselves. For instance, in November 2023, Microsoft, a US-based technology company, launched Microsoft Cloud PKI in the Microsoft Intune Suite. Microsoft Cloud PKI automates the processes of certificate issuance, renewal, and revocation, reducing the complexity typically associated with managing a Public Key Infrastructure (PKI). Organizations can establish a cloud-based PKI environment in minutes rather than weeks, eliminating the need 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 move towards passwordless environments. Microsoft Cloud PKI includes a registration authority that automatically deploys certificates to Intune-managed devices across multiple platforms, including Windows, iOS, Android, and macOS.

What Are Latest Mergers And Acquisitions In The Public Key Infrastructure Market?

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