Resilience Assurance

Prove failover will work, before it has to

Redundancy that is assumed is not redundancy. REAP inventories the redundancy relationships it can see and flags standby pairs that are out of sync, drift from recorded configuration, and CVEs that matter because of the features you run, each finding with evidence an auditor can read. Backup-path capacity and continuous failover-readiness proof are In development.

The buyer’s question

“Will failover actually work?”

You paid for redundancy: a second circuit, a standby firewall, a second core. Can you show your auditor, your insurer or your board that it works today? Failover was tested at commissioning. Since then: a standby that stopped synchronizing, a backup circuit that cannot carry peak load, drift on forty access switches, and a CVE (opens in a new tab) that matters because of the feature you enabled. Start before the audit, the circuit renewal or the failover you did not plan.

Design-partner seats

For teams whose redundancy is audited or insured and whose HA pairs span vendors: early access and a say in what counts as proof, in exchange for structured feedback.

What you get

Outputs, not dashboards

Findings you did not know

Pilots target at least three previously unknown material risks, confirmed by your architect, for example, a firewall pair whose standby cannot be seen or is out of sync, with the reason and the configuration change that fixes it.

Exposure in context

Which CVEs matter here, because of what the device runs and what sits behind it.

Audit evidence from live state

In pilots with audit scope: configuration and segmentation evidence produced from live configuration and topology, not screenshots gathered over weeks.

Evidence shown

Every conclusion, traceable

Week 3 of a pilot is a findings review with your architect: each finding carries severity, evidence and a recommended fix.

Finding

Backup circuit DRS-WAN-B is 100 Mb/s (interface bandwidth and carrier order). Business-hours 95th-percentile load on the primary is 240 Mb/s. Failover would succeed and then congest.

Why it matters

MES and plant telemetry share the backup with all other traffic and no QoS class protects them, so a daytime failure drops production telemetry with everything else. Nightly backups (peak 310 Mb/s) matter only for a night-time failover.

Severity and exposure

High Since the June bandwidth change on the primary; no alarm exists for this condition today.

Recommended fix

QoS class for MES and telemetry on DRS-WAN-B; an alert when business-hours p95 on the primary exceeds 80% of backup capacity; the backup upgrade in the next budget cycle. Verify with a failover test in the next maintenance window.

Evidence

  • W3interface counters DRS-WAN-A, 5-min samples, pilot days 1–16→ business-hours p95 240 Mb/s · peak 310 Mb/s (02:00 backups); the plant NMS 90-day export agrees
  • W3interface config DRS-WAN-B + ServiceNow CHG-1877 (June)→ bandwidth 100000; primary raised to 500 Mb/s, backup unchanged
  • W3QoS policy DRS-WAN-B→ no class for MES traffic
  • W3path trace MES VLAN 310 → MES servers→ primary and failover paths both use the DRS WAN pair; OSPF prefers WAN-A
  • W3finding confirmed by the plant network architect
