Market Definition
Public Key Infrastructure (PKI) is a framework of encryption and cybersecurity technologies that secures communication and transactions over networks such as the internet. PKI uses a pair of cryptographic keys — public and private — to authenticate users, devices, and services, ensuring secure digital interactions.
PKI enables organizations to:
- Encrypt sensitive data
- Sign digital documents
- Authenticate devices and applications
- Secure cloud-based environments
- Support compliance with regulatory requirements
Growth Drivers
1. Increasing Cybersecurity Threats
With the rise in ransomware, phishing attacks, and data breaches, PKI has become an essential security component for organizations. The demand for strong identity verification and secure communication channels is driving PKI adoption globally.
2. Rapid Digital Transformation
Organizations are digitizing processes and migrating to cloud environments. PKI solutions provide critical support in securing these transitions by enabling encrypted communications, secure user authentication, and digital trust.
3. Growth in IoT and Connected Devices
IoT devices need strong security frameworks to protect data exchanges and prevent cyber intrusions. PKI provides device identity management and secure communication capabilities, making it indispensable in the IoT ecosystem.
4. Compliance with Regulations
Various data protection regulations such as GDPR, HIPAA, PCI DSS, and eIDAS have mandated strong encryption and secure authentication mechanisms, encouraging the use of PKI.
5. Rise of Remote Work Culture
Remote and hybrid work models post-pandemic have increased the need for secure remote access, VPNs, and digital identity management, further driving PKI deployments.
