Public Key Infrastructure (PKI) plays a critical role in Zero Trust by enabling strong cryptographic identity verification for users, devices, applications, and servers.

PKI supports Zero Trust through:

• Certificate-based authentication (passwordless access)
• Secure device identity verification
• Digital signing and encryption
• Secure API and microservices communication

eMudhra’s PKI and Certificate Lifecycle Management (CLM) solutions also ensure:

• Automated certificate issuance and renewal
• Secure storage of keys in Hardware Security Modules (HSMs)
• Compliance with global standards
• Prevention of certificate-related outages

PKI eliminates reliance on weak credentials and strengthens trust across enterprise systems.
