Are offline token verification and failover enough for attestation continuity?

TL;DR: Mobile app attestation fails operationally when the security service becomes a live dependency in the request path, according to Approov. Backend-local verification, cross-cloud failover and app-side continuity handling keep protected apps operating when token issuance is unavailable.

Editorial analysis by NHI Mgmt Group, based on content published by Approov: “Built for Continuity: What Happens if Approov Goes Down?”.

Key questions

Q: When should organisations allow tokenless access during an attestation outage?

A: Only when an authorised continuity policy explicitly permits it and the exception is time-limited.

Q: What signs show that an attestation control is failing in practice?

A: Look for repeated NO_APPROOV_SERVICE events, declining token issuance, unexpected dependence on a single cloud or domain, and API traffic that stops even though the backend is otherwise healthy.

Q: What breaks when mobile attestation depends on a live service call?

A: The control becomes an availability dependency, so a service outage can block token issuance even when the app and backend are healthy.

Practitioner guidance

  • Define a tokenless emergency path Document when API requests may proceed without an attestation token, who approves that state, and when the temporary exception is revoked.
  • Verify backend-local JWT enforcement Confirm that the backend validates attestation tokens locally with a shared secret and does not rely on a live callback to approve requests.
  • Test failover as an operational control Exercise the primary-to-failover transition in staging and production-like drills, including the independent cloud, different domain, and no-app-change path.

Bottom line: Mobile attestation fails operationally when the security service becomes a live dependency in the request path.

Availability is part of identity control, not a separate concern. When attestation or machine-identity validation sits in the request path, outages can become security outages as quickly as service outages. This article shows the right governance question: can the protected application continue to enforce trust when the attestation provider is unreachable? Practitioners should treat continuity as a property of the identity control itself, not as an afterthought.

A question worth separating out:

Q: How do teams keep attestation and business continuity from conflicting?

A: Separate the security decision from the emergency decision. The attestation system should prove trust, while the backend continuity policy should decide whether a temporary exception exists. That split preserves enforcement under normal conditions and gives the enterprise ownership of the fallback during disruption.
