Public Key Infrastructure Market Size

Public Key Infrastructure Market Size

The global public key infrastructure market size was valued at USD 4.7 billion in 2024 and is projected to grow at a CAGR of 22.3% between 2025 and 2034. Governments and regulatory bodies worldwide are enforcing stringent frameworks, including GDPR, HIPAA, PCI-DSS, and CCPA, to protect sensitive data and ensure secure digital transactions. These regulations compel organizations in sectors such as BFSI, healthcare, and government to implement advanced security solutions like Public Key Infrastructure (PKI).

PKI is essential for achieving compliance by enabling secure authentication, encryption, and digital signatures that safeguard data integrity and privacy. Non-compliance often results in significant penalties and reputational harm, further driving organizations to adopt PKI solutions. As regulatory frameworks evolve to address emerging cybersecurity threats, the demand for PKI is expected to rise, propelling market growth.
 

Moreover, the growing sophistication and frequency of cyberattacks are key drivers of the public key infrastructure industry growth. Cyber threats, including phishing, ransomware, and data breaches, increasingly target sensitive information across various industries. Consequently, organizations are adopting PKI as a vital solution to strengthen their security frameworks. PKI enables secure encryption, authentication, and digital signatures, effectively mitigating risks associated with cyber threats. It ensures the protection of sensitive transactions, facilitates secure data exchanges, and enhances access control mechanisms.
