TL;DR: Teleport shows that hybrid infrastructure multiplies identity silos, static credentials, and blind spots across cloud accounts, data centers, and colocated environments. The practical shift is to move access decisions into a shared identity layer with short-lived certificates, workload identity, and protocol-level enforcement instead of relying on VPNs and bastions.
Editorial analysis by NHI Mgmt Group, based on content published by Teleport: “Guide: How to Unify Identity Across Cloud and Data Center Infrastructure”.
Key questions
Q: What breaks when hybrid infrastructure relies on separate identity systems for each site?
A: Identity fragmentation breaks central governance because policy, logs, and credential lifecycles split across environments.
Q: Why do static credentials create more risk in hybrid infrastructure?
A: Static credentials tend to spread across sites, survive role changes, and remain valid long after the original need has passed.
Q: How should security teams unify identity across cloud and data center environments?
A: Start by standardizing trust anchors, then issue short-lived credentials from a shared authority, and finally enforce access at the protocol layer.
Practitioner guidance
- Anchor on a hardware root of trust Use TPM attestation or Kubernetes JWT federation to give on-prem and workload identities a trust anchor comparable to cloud-native identity systems.
- Replace static credentials with short-lived certificates Issue expiring certificates for users, machines, and automation so access ends when the certificate ends rather than after manual revocation.
- Standardise workload identity across sites Use SPIFFE-compatible workload identities for service-to-service access so cloud and bare-metal workloads do not depend on cloud-specific secrets.
Bottom line: Hybrid estates become harder to govern when every environment uses a different identity and access model.

Identity fragmentation is the core governance failure in hybrid infrastructure. When each cloud account, data centre, and colocation site runs its own identity configuration, the organisation no longer has one access model. That breaks the assumptions behind centralised governance, because access review, logging, and offboarding all become environment-specific chores instead of a single lifecycle.
A few things that frame the scale:
- Organisations maintain an average of 6 distinct secrets manager instances, creating fragmentation that undermines centralised control, according to the State of Secrets in AppSec.
A question worth separating out:
Q: Should organisations replace VPNs and bastions with identity-based access controls?
A: Yes, when the goal is stronger governance over infrastructure access. VPNs and bastions can reduce exposure, but they do not solve credential reuse, lateral movement, or poor visibility. Identity-based access controls are the better fit when organisations need per-session enforcement and auditable protocol-level access.
