The global market for Public Key Infrastructure (PKI) was estimated to be worth US$ 5338 million in 2024 and is forecast to a readjusted size of US$ 16280 million by 2031 with a CAGR of 17.4% during the forecast period 2025-2031.
Public Key Infrastructure (PKI) is a system of technologies, policies, and procedures used to create, manage, distribute, use, store, and revoke digital certificates and public-private key pairs. It enables secure electronic communications and transactions over untrusted networks such as the internet. PKI uses asymmetric encryption, where a public key is used to encrypt data and a private key is used to decrypt it. It ensures the confidentiality, integrity, authenticity, and non-repudiation of digital information. Common applications of PKI include securing websites (via SSL/TLS), digital signatures, email encryption, and identity verification.
North America is the largest regional market for Public Key Infrastructure (PKI), accounting for 33.64% of the global market share in 2023. This is attributed to the region's high level of technological maturity, extensive regulatory requirements, and continuous investments in cybersecurity. North America is expected to maintain its significant position in the global PKI market through 2030. Europe ranks as the second-largest regional market, driven by strict regulations, particularly the implementation of the General Data Protection Regulation (GDPR) and the Electronic Identification, Authentication and Trust Services (eIDAS) Regulation. The Asia-Pacific region-especially China, India, and Japan-is rapidly emerging as a key market for PKI. The region is expected to record the highest compound annual growth rate (CAGR) globally, primarily due to the rapid growth of e-commerce, FinTech, the Internet of Things (IoT), and cloud computing.
PKI is widely used across various industries: In the financial services and insurance sector, PKI is extensively applied to secure online transactions and electronic signatures, ensuring safe data transmission and identity verification. Government agencies use PKI to secure the transmission of sensitive information and protect e-government applications, particularly in defense and intelligence departments where confidentiality in communication is critical. In the telecommunications sector, PKI supports secure communication protocols and ensures the safe transmission of data across networks. In 2023, the financial services and insurance sector accounted for approximately 26.52% of the market share, with a projected CAGR of around 17.01% in the coming years.
