Inline uptime is your uptime.

Because every AI action in your organisation passes through Xybern before it executes, our availability is your AI availability. We treat uptime as an operational obligation, not a marketing number.

The inline availability problem

For an inline enforcement system, uptime is operational continuity.

If your analytics platform goes down, dashboards are unavailable. If an inline enforcement layer goes down, the question is whether your agents run without enforcement. We designed the answer to always be no.

AI never runs unenforced

Even during an incident, no agent action executes without passing the layer first.

Fail-closed by default

If the layer is unreachable, actions queue at the boundary. Nothing slips through.

Queued, then replayed

Held actions are processed in sequence on recovery, so nothing is lost and nothing is unrecorded.

No regulatory gap

There is no window of unrecorded, unverified activity to explain to a regulator later.

Fail behaviour

Fail-closed by default. Configurable. Always explicit.

Fail-closed is a deliberate architectural choice, not a fallback. We explain each option with its full consequence, because you should choose your fail behaviour consciously.

Fail-closed

The Xybern default. Actions queue and none execute while the layer is unreachable, with a full record maintained and zero exposure during the outage.

Fail-open

Not the default. Actions execute without enforcement during an outage, leaving an unrecorded window. Available only as an explicit, documented choice.

Replay on recovery

Every queued action is processed in order the moment the layer recovers.

A conscious choice

You choose the behaviour deliberately, per workspace, with the trade-off stated plainly.

Operations

Watch it, and hold us to it.

A live health signal, a defined incident response, and a published uptime history, so availability is something you can verify, not just read.

Health API

A live endpoint for the enforcement layer so you can monitor availability yourself.

Incident response

A defined response with sub-second detection and clear communication during any event.

Uptime history

A published record of availability against the 99.9% SLA.

Reliability review

A walkthrough of the availability architecture and fail behaviour for your operations team.

Uptime you can hold us to.

We will walk your operations team through the availability architecture, the fail behaviour, and the numbers behind the SLA.
