Keys that open only their doors.
Scoped API keys that grant an integration only the endpoints it actually needs and nothing more — least privilege at the credential level keeps a compromised key’s blast radius small.
1. The all-access key is the liability
The path of least resistance is a single powerful key that can do everything — and that is exactly the credential whose leak is catastrophic. Service-Key inverts the default: an integration receives a key scoped to the specific endpoints it uses, so its capabilities match its job and nothing more. The reporting job’s key reads summaries; it cannot write, cannot delete, cannot reach another tenant.
2. Scoping as a routine, not a project
Least privilege only happens if it is easy. When scoping a credential is a heavyweight task, teams reach for the broad key “for now.” Making scoped keys the normal way to issue access — pick the endpoints, mint the key — is what keeps the principle alive as integrations multiply.
3. How B5 Secure handles it
B5 Secure issues Service-Keys scoped to the endpoints an integration needs, enforced in the pipeline alongside IP binding and authorization. A compromised key authenticates only to its allow-listed surface — and, where IP-bound, only from its expected network — so the cost of a leak is bounded by design.
