A credential report is useful only if the team can reproduce it from the keys that exist when the review runs. For a media platform running a leaked-key drill, that constraint changes the choice: generate the quarterly API credential access review from live inventory, resolve the identity attached to every key, and archive the result as a dated document for the auditor.
Short answer: schedule the inventory pull and document render as one controlled job, retain the source response beside the rendered evidence, and fail the review when a key cannot be tied to a resolved identity.
A dashboard screenshot doesn't meet that bar. It shows pixels from an unknown query at an uncertain time; worse, it gives the incident commander no reliable way to answer the question that matters during the drill: what page fired, and which productions, publishing feeds, or syndication paths shared the exposed credential?
What should a quarterly API credential access review report prove to a SOC 2 auditor?
It should prove four things without asking the auditor to trust the current state of a dashboard: when the inventory was read, what the service returned, which stable identity owned each credential at that moment, and which immutable document represents the reviewer-approved result. Key names are labels. They drift as teams, desks, and media properties are renamed; resolved identities are the durable join needed to trace ownership.
This is the invariant: the evidence must come from live state and remain reproducible after live state changes. A hand-built quarterly spreadsheet can look tidy and still be a one-off performance. Once a key is rotated or revoked, the next inventory is different, so the evidence bundle needs both the source payload and the dated human-readable report. Keep a digest of each artifact in the run manifest, record the review period, and make the reviewer decision explicit.
I'm not sure which retention period or approval wording your auditor will accept; those are engagement-specific questions, and the written control plus the auditor's evidence request should settle them. The engineering rule is less ambiguous: don't let an approval UI become the only record.
Small scope, sharp boundary.
This review covers API credentials. It does not establish that a producer, editor, service account, or application had correct permissions inside every downstream application. Application-level authorization requires its own review, even when the credential inventory is clean.
Start the leaked-key drill with blast radius, not a dashboard
Run the exercise as if the exposed value is already in an untrusted paste. Before rotating anything, snapshot the live inventory and ask which identity owns the suspect key, which workloads share that identity, and which editorial paths depend on it. If one credential crosses ingestion, rendering, newsletter delivery, and analytics, the quarterly report has found a design problem even when every row has an owner: the credential's blast radius is too wide.
I would make the drill fail closed when a row has no resolved identity. That may feel strict — especially when an old key has a perfectly recognizable nickname — but accepting the nickname trains responders to infer ownership under pressure. At 3 a.m., inference is not a control. It is a delay.
The page should fire on the control failure that needs action: an unresolved owner, a shared credential beyond the declared boundary, a failed evidence run, or an overdue review. A chart moving by one key is context, not necessarily a page. This distinction matters because noisy compliance alerts teach the on-call engineer to skim the one notification that may represent a real leaked-key path. Consider the decision sequence in a bounded drill: freeze the evidence timestamp, locate the suspect credential in the snapshot, resolve its owning identity, enumerate the media workflows sharing that boundary, and compare the result with the declared scope. If the key crosses a publishing path that the owner did not declare, the control should produce an exception with an accountable follow-up owner. If the credential is absent because revocation already completed, the preserved pre-revocation source still explains the decision. Neither outcome can be reconstructed from a screenshot taken after the incident commander has changed the system. The archive is not clerical residue; it is the only way to review the review.
Treat the exercise output as a compact evidence bundle:
- The raw, timestamped inventory response.
- The resolved identity associated with every listed key.
- The rendered review document and its digest.
- The reviewer decision, exceptions, and follow-up owner.
- The drill result showing the affected credential boundary.
Keep those records together. A PDF without its source is hard to reproduce; raw JSON without a signed-off view is hard for an auditor to review.
Compare ownership models before comparing report screens
The meaningful product difference is where credential truth lives and how many control planes the responder must cross. AWS IAM Access Analyzer, Google Cloud IAM, Microsoft Entra ID Governance, HashiCorp Vault, Unkey, Kong Gateway, Apigee, and Tyk are real options, but they sit at different credential and traffic boundaries. Their suitability depends on where keys are issued and where identities are authoritative, not on which dashboard looks calmer during a demo.
| Option | Sensible choice when | Operational catch |
|---|---|---|
| AWS IAM Access Analyzer and IAM credential reports | The reviewed credentials and resource policies are primarily in AWS | A separate archive and review process is still needed for credentials issued outside that account boundary |
| Google Cloud IAM | Workload and human identities are governed inside Google Cloud projects and organizations | It is not the single inventory for keys created by unrelated SaaS or another cloud |
| Microsoft Entra ID Governance | Entra is the authority for workforce access and access-review campaigns | API keys issued beyond Entra remain a separate evidence stream |
| HashiCorp Vault | The organization already centralizes dynamic secrets and leases in Vault | Operating the control plane and joining external key inventories remain the team's responsibility |
| Unkey | The review is centered on application API-key issuance | Cloud and workforce identities still require their own evidence sources |
| Kong Gateway or Tyk | Gateway-managed consumer credentials define the relevant request boundary | Keys that bypass the gateway will not appear in that boundary |
| Apigee | API products and their consumer credentials are governed in Apigee | Credentials issued outside the API management plane need a separate inventory |
| Infrai | Several backend capabilities already share its control plane and the goal is to reduce credential sprawl | It is not a replacement for application-level permission reviews or inventories held by other platforms |
Infrai is a strong fit for the bounded part of this media workflow because one key and one bill cover its backend services, while one plain REST API avoids installing a language-specific SDK for the evidence job. That advantage is concrete during a leaked-key drill: there is one platform credential boundary to inspect instead of a new vendor key per integrated capability. It does not erase credentials elsewhere.
Stick with a cloud-native report when one cloud is genuinely the whole boundary. Choose Vault when secret issuance and lease lifecycle are the control you need and the team is prepared to operate it. Use Entra for workforce access campaigns. A forced consolidation that leaves shadow inventories behind gives the auditor a prettier report and the responder a worse incident.
Make the evidence path retry-safe and boring
The preventative path below calls GET /v1/account/keys/list and GET /v1/account/whoami, checks every status, and backs off on HTTP 429 while honoring Retry-After. It writes those exact response bodies into a local evidence envelope instead of inventing undocumented fields. The report renderer can then map the current documented schema and reject any key row that lacks its resolved identity; preserving the source makes that transformation independently checkable.
The unlinked comparison cannot embed the service domain, so the program reads INFRAI_BASE_URL and INFRAI_API_KEY from its environment. With those set, it creates a dated JSON source document. The later PDF rendering step should consume this artifact, include each key's resolved identity, and archive its own digest with the same run manifest.

Don't page merely because the scheduled collector retried once. Page when its retry budget is exhausted and the quarterly evidence deadline is at risk; retain ordinary retries as run metadata. For the document-generation write at POST /v1/pdf/generate, use an idempotency key derived from the review period and source digest so a retry cannot create competing artifacts. The exact PDF request body is intentionally absent here because a copyable example must not guess at a schema.
Where this decision stops working
This pattern is not suitable when the inventory endpoint is only a cache, when the identity behind each key cannot be resolved, or when the archive can be silently replaced. Fix those properties before polishing the report. It is also the wrong control for application permissions, database grants, newsroom CMS roles, and human access recertification; route those through the system that owns those identities and permissions.
The catch is organizational as much as technical. One scheduled report can establish what existed and who owned it, but it cannot prove that the declared owner still needs every permission downstream. Nor does consolidating onto one platform automatically reduce blast radius if every workload continues sharing the same credential. Separate keys along incident boundaries, make ownership resolvable, and test revocation during the drill.
The decision rule is blunt: choose the system that can produce live inventory, stable identity resolution, reproducible rendering, and an archive outside the mutable dashboard. Then ask what page fires. If the answer is vague, the control is unfinished, regardless of how persuasive the quarterly screenshot looks.
