Public Key Infrastructure Market: Understanding Its Role in Securing Data in the Cloud

Posted on 10-February-2024

A public key infrastructure (PKI) is a platform that supports managing digital certificates for implementing strong authentication, electronic signature and data encryption methods. The Public Key Infrastructure service is integrated with other security and IoT managed connecting devices as smart M2M and a part of IoT Security solutions that includes CyberThreats, and Faast IoT technology. Public Key Infrastructure (PKI) caters highest revenue to the e-signature market.
One of the cornerstones of modern cybersecurity is the Public Key Infrastructure (PKI), a framework that facilitates secure communication and data exchange in the digital realm. As businesses and governments alike recognize the importance of securing their digital assets, the PKI market is experiencing unprecedented growth and evolution.
 

Understanding Public Key Infrastructure (PKI):

At its core, PKI is a set of policies, procedures, hardware, software, and standards that work together to establish, manage, distribute, use, store, and revoke digital certificates. These certificates, consisting of public and private keys, play a crucial role in authenticating the identities of users and devices, encrypting sensitive information, and ensuring the integrity of data in transit.
 

Market Size & Dynamics:

Global Public Key Infrastructure market is projected to reach US$ 12680 million in 2029, increasing from US$ 3980.5 million in 2022, with the CAGR of 17.7% during the period of 2023 to 2029.
The PKI market has witnessed remarkable expansion in recent years, driven by the escalating frequency and sophistication of cyber threats, the proliferation of digital identities, and the growing adoption of cloud-based services. According to various industry reports, the global PKI market is expected to reach unprecedented heights in the coming years, fueled by a compound annual growth rate (CAGR) that reflects the dynamic nature of the cybersecurity landscape.
 

Key Drivers:

  1. Rising Cybersecurity Concerns: With cyber threats becoming more advanced and prevalent, organizations are increasingly investing in robust security infrastructure. PKI provides a strong foundation for securing sensitive data and communications, making it a critical component of modern cybersecurity strategies.

  2. Digital Transformation Initiatives: The ongoing digital transformation across industries is creating a surge in the number of connected devices and digital transactions. PKI enables secure authentication and communication in this digital landscape, fostering trust and mitigating the risks associated with the expanding attack surface.

  3. Stringent Regulatory Compliance: Governments and regulatory bodies worldwide are imposing stringent data protection and privacy regulations. Compliance with these regulations often requires the implementation of strong encryption and authentication measures, driving the demand for PKI solutions.

  4. Cloud Adoption: As businesses migrate their operations to the cloud, securing data in transit and at rest becomes paramount. PKI solutions provide a secure framework for managing cryptographic keys, ensuring the confidentiality and integrity of data in cloud environments.
     

Market Challenges:

While the PKI market is poised for significant growth, it also faces several challenges that industry players must address to capitalize on the burgeoning opportunities.
