Machine Identity # Machine Identity Certificates and identities for machines, services, and workloads. 8 vendors · Last updated 4 days ago Quick answer ## What is Machine Identity? Short answer Machine identity platforms issue and manage certificates, keys, and credentials for servers, workloads, and machines — at scale and across hybrid environments. Best for Platform and security teams managing TLS, mTLS, and workload identity across cloud and on-prem environments. When to choose Look at PKI coverage, automation depth (renewal, rotation), and integrations with Kubernetes, service meshes, and cloud KMS. When not to choose Skip Machine Identity tooling if a broader IAM platform already covers your needs and you don't have category-specific requirements.
