 How will the certification and authentication process affect our workflow?1
 Can I see a flowchart or diagram explaining the authentication and registration process?
 Who are some of your current and previous customers?1
 What steps have you taken to guarantee 24/7 access for authentication and registration?1
 What is the total cost of implementing your PKI solution?
 How does the cost break down?
 What support will you give my company, and how much will it cost?2
 Can you explain how the registration authority interface works?3
 Is the registration authority operation separable from the certificate authority?
 Are bulk registration operations supported?3
 Did you license or develop the cryptography technology?3
 Can your certificate authority accept an externally supplied signing certificate? (Gartner recommends that the certificate authority use x.509 v.3-compliant certificates, the current standard. Only one company–PGP–does not use this.) 3
 Does the certificate authority back up private keys for escrow and recovery? 3
 Can certificates be archived? 3
 Does the certificate authority use non-rewriteable media to ensure archive and audit integrity? 3
 What additional services are offered? (According to Gartner, notary services, time stamping, and key histories will come into play during auditing of electronic signatures.) 3
