What we sustain

The whole estate between the control room and the field.

Across six component classes and 150+ failure modes, OT Continuum watches the things that fail quietly until they don't — and owns the work to keep them healthy.

Component coverage

Every layer of the OT stack.

Each class carries its own structured failure taxonomy. These are representative — the full model runs deeper.

HMI & Workstations

Operator & engineering stations

  • ·Patch drift
  • ·Windows OS failures
  • ·Account / credential failures
  • ·Configuration drift

Backup

Backup systems & agents
  • ·Job failures
  • ·Restore-point issues
  • ·Retention misalignment

Live

Vulnerabilities and vendor end-of-life — the most annoying sustainment work there is.

OEM advisories arrive as a firehose covering products you don't even run. End-of-service and end-of-warranty notices land in an inbox and get forgotten until something breaks in a window you can't afford.

OT Continuum filters advisories to the equipment you actually own, ties each one to the asset and the production it affects, and turns end-of-life dates into a planned countdown — not a surprise.

How a signal enters

Eight ways risk surfaces — all routed the same way.

Whether a health check fails, a technician walks one up, or a vendor issues an advisory, it lands in one queue, triaged and tied to production impact.

Why this is the work that matters

The things that actually take plants down.

When OT causes lost production, it's rarely exotic. It's the quiet, deferrable stuff — exactly the work that slips when one person is tracking it by hand.

Obsolescence & end-of-service

Aging hardware and unsupported software on a ~10-year cycle — the slug nobody plans for until it arrives.

Simplex & lost redundancy

Critical control running non-redundant, or redundancy that's quietly degraded — invisible until failover doesn't.

Patch & config drift

Overdue patches and silent configuration drift that accumulate into exposure no one is watching.
