Many organizations focus heavily on protecting human identities but overlook machine identities, leaving keys and certificates vulnerable to misuse, expiry, or compromise. Weak machine identity practices can cause outages and enable attackers to exploit trusted systems. CyberArk highlights ten key questions PKI teams should address, including visibility into all machine identities, cryptographic strength, centralized control, key secrecy, and rotation frequency. Other priorities include response to compromises, avoiding duplication, rapid revocation, restricting issuance, and proper configuration. Strengthening these areas ensures consistent enforcement, reduces risks, and closes critical security gaps.
