Public Key Infrastructure Market Growth & Trends

The global public key infrastructure market size is estimated to reach USD 19.65 billion by 2030, expanding at a CAGR of 21.1% from 2025 to 2030, according to a new report by Grand View Research, Inc. The public key infrastructure (PKI) market is driven by the increasing adoption of enterprise key management among IT and security professionals, growing adoption of smart technologies and distributed applications, and the advent of 5G. While cyber security envisages a more comprehensive approach to securing the overall digital ecosystem, data security is more focused on securing the data the digital ecosystem generates and stores by rolling out various primary protection layers. Putting a strong emphasis on encryption, access controls, data categorization, and data masking; data security ensures that the data remains secure continuously.

Technologies such as Artificial Intelligence (AI) and Machine Learning (ML) are empowering data-centric security solutions to predict threat identification and response. These technologies examine vast data volumes to uncover patterns and variations, helping detect zero-day threats and complex attacks. Further, the adoption of Zero Trust Architecture (ZTA) is altering data security strategies. ZTA implies no inherent confidence within or beyond the network boundary, necessitating stringent authentication and permission for all users and devices. This method adheres to the data-centric idea of limiting data exposure to only authorized entities. These factors would further drive the public key infrastructure (PKI) market during the forecast period.

A huge amount of data collected and processed necessitates a scalable security solution. Data security is centered on data protection, providing an adaptive strategy that corresponds with the growing volumes of data and personal information being processed by organizations. Big data and private data have enormous value for businesses in terms of insights, analytics, and consumer knowledge. Businesses can confidently leverage the opportunity of big data and personal information by implementing data-centric security solutions, without exposing themselves to the dangers associated with data breaches, unauthorized access, and privacy violations. The use of this strategy aims to promote innovation and develop a culture of trust among consumers, partners, and stakeholders. These factors would further drive the public key infrastructure (PKI) market during the forecast period.
