FAQs
What is PKI software?
Public Key Infrastructure (PKI) software creates, manages, and validates digital certificates that secure data, identities, and transactions. In practice, PKI enables encryption, authentication, and digital signatures across business systems and applications, protecting sensitive information while allowing people to work seamlessly. Entrust introduced the world’s first commercial PKI in 1994.
What does PKI management entail?
PKI management entails the full lifecycle of digital certificates, from issuance and renewal to revocation. A properly set up and run PKI with strong policies, ensures that only trusted users, devices, and applications gain access to your systems. Entrust simplifies this with flexible deployment models: on-premises for maximum control, managed PKI for cloud-driven scalability and automation, or as-a-Service for a turnkey solution for your core business use cases.
What is the most popular use case for PKI?
PKI is widely used for securing websites with SSL/TLS, authenticating users and devices, and enabling encrypted email and digital signatures. Today, organizations also use PKI for cloud security, IoT devices, and hybrid workforce access. Entrust PKI solutions are designed to support a range of critical use cases while staying ahead of compliance and regulatory needs.
How do I choose the right PKI vendor?
The right PKI vendor should deliver a balance of security, usability, and compliance. Look for proven expertise, global trust, flexible deployment options, and integration with your existing systems. And as the quantum threat approaches, as with any technology vendor, you’ll want to ensure your PKI vendor has a clear roadmap to support post-quantum cryptography. Entrust PKI solutions are PQ secure, flexible and designed to scale with your business needs, while keeping complexity low and security uncompromised.
