Understanding the Different Types of PKI Solutions:
Private PKI, Public PKI, Managed Cloud PKI, and Hybrid PKI

Private PKI

Private PKI (Private Public Key Infrastructure) is a security framework that an organization sets up and operates internally, independent of external certificate authorities. Private PKI offers robust system to implement specific needs of the organization to provide secure access to users, devices, and applications. With Private PKI organizations can enforce moderate or higher security standards to meet data security compliance without relying on external CAs.

Think of it like managing access to a building: just as employees use keycards or fingerprints to enter, Private PKI allows an organization to control access to its digital infrastructure. With a Private PKI, an organization can issue and track digital certificates, which act as digital ID badges. This means that only verified as well trusted identities (on-roll and agencies’ appointed employees, devices, or applications) can access internal resources.

We offer a range of Private PKI solutions, supported by robust systems for certificate issuance, from trusted brands. This solution gives organization scalable control to centrally manage digital identities for all authorized devices, applications, and users.

Use Cases

  • Internal Network Security and Authentication for User, VPN, Wi-Fi Access and more
  • Zero Trust Security and IoT (Internet of Things) Device Authentication
  • Document and Workflow Signing and Software Signing
  • Email Encryption and signing for Secure Messaging
  • DevOps Security and CI/CD Pipeline Security

Public PKI

Public PKI is an advanced version of Private PKI where an external Certificate Authority (CA) verifies the identities of users, devices, and applications of certificates requestors. This approach helps enterprise to replace the complex task of managing a PKI infrastructure with trusted public CAs. Public CAs are responsible for securely issuing and revoking digital certificates, and they often provide assurance warranties with their issued digital licenses.

CRLs and OCSP mechanisms offered with public PKIs make them more trustworthy and widely adopted by small and large enterprises. Both these ensures that revoked certificates are publicly logged and marked as unsafe that provides a high level of visibility and security for certificate status.

Use Cases

  • SSL and TLS certificates for connecting users to websites on secure protocol
  • Encrypting and signing messages for email authenticity and security
  • Code signing certificates that verifies integrity of code and software
  • Document signing that ensures documents’ authenticity
  • Users and device’s identity and authentication for secured network access

Managed Cloud PKI

Cloud PKI is a managed solution of public PKI hosted entirely on a cloud enviornment. In this the PKI infrastructure and certificate lifecycle management are fully managed by the provider. This system provides additional flexibility, scalability, and API driven integration, making it easy to automate certificate management processes.

Features and Advantages

  • Fully Hosted in the Cloud: Offers ease of use, allowing organizations without PKI expertise
  • Automatic Scalability: Start with minimum requirements and scale up with infrastructure requirements
  • API Integrations: Integration with third party systems for certificate issuance, renewals and revocation
  • Automated Certificate Management: Automated renewals to prevent certificates related outages
  • High Availability and Resilience: Reliable system with backups and failover for guaranteed uptime
  • Cost Efficiency: Cloud based systems are typically scalable and cost-effective that offers controlled cost management

Hybrid PKI

Hybrid PKI is a well-managed and smart combination of Private and Publick PKI to leverage the security and scalability of both systems. This hybrid model uses public CA for certificates issuance for externally accessed identities and private CA for certificates used in enclosed digital infrastructure. This highly reliable approach provides flexibility, security and management for both internal and external resources.

Features and Advantages

  • Custom Policies: Set common as well different rules and policies for public and private systems to match your organization’s needs.
  • Centralized Management: Single window for all certificates management offers simplified UI access to administrators to manage renewals and revocations.
  • Smooth Integration: Works with both external and internal applications in real-time to secure internal and external devices.
  • Enhanced Security: With Hybrid PKI, you get strong security for internal applications and taking advantage of the reliability of public PKI for anything external.
  • Flexibility and Scalability: Easy to scale up with public PKI for external needs, while still having control over internal PKI to adjust security and operational settings as needed.
  • Cost Savings: Use private PKI for internally uses certificates to control costs over public certificates.
  • Compliance Ready: Supports privacy and regulatory requirements to help your organization qualify for enterprise level standards and compliance.
