Critical infrastructure that fails safely.
The blast radius is national. AU SOCI 2018+amendments, EU NIS2, US CIRCIA — the regulators are converging on the same shape: known supply-chain, evidenced controls, fast incident reporting, tested resilience. IT/OT convergence is the hard part: the substrate of one sector can’t pretend the other doesn’t exist.
The regulatory floor — critical infrastructure
- AU SOCI Act 2018 + 2022 SLACIP amendments · mandatory risk programmes, fast incident reporting
- EU NIS2 Directive · enforced; expanded scope; board accountability
- US CIRCIA · covered-entity 72-hour incident + 24-hour ransom-payment reporting
- IEC 62443 · the OT-security standard floor (industrial control systems)
- NIST SP 800-82 · OT cybersecurity guidance, latest revision
- SLSA v1.0 + SSDF · supply-chain attestation for IT/OT integration points

The two diagnostics that surface the most critical infrastructure-specific exposure. Each takes 2–4 minutes; results are shareable via URL hash; nothing is stored.
DevSecOps Maturity
Supply-chain, identity, patching, observability. The SOCI/NIS2 risk-programme conversation reduces to these capabilities for the IT side of the estate.
Open →DiagnosticSRE Programme
Error budgets, blast-radius, postmortems, runbooks. The resilience-testing obligation in NIS2 + DORA + SOCI is measured against this shape.
Open →Reference architectures.
Opinionated paved-paths sized for critical infrastructure constraints — data residency, audit, supply-chain attestation, change-control.
DevSecOps SLSA L3+ Paved Path
Build provenance + signed images + admission control. The IT-side substrate for SOCI / NIS2 supply-chain obligations.
Open →Reference architecturePlatform Engineering IDP
Inherited golden signals + ownership + observability. The substrate that makes incident detection deterministic.
Open →Reference architectureRegulated GenAI Platform
For operators starting to use GenAI in operational planning / SCADA-adjacent contexts — with the audit pipeline + guardrails the sector needs.
Open →Where critical infrastructure teams typically get stuck.
The most-common Tier 2 stuck-points in this sector, with the three substrate moves to the next tier.
SRE — Operational
DORA Medium cluster. Three moves: define + enforce error-budget policy for top 3 services, track + bound toil, build + test runbooks for top 10 alert types.
Open →Stuck tierDevSecOps — Repeatable
The IT-side gap that SOCI/NIS2 audits expose. Three moves: workload identity, SBOM owner-loop, policy-as-code at admission.
Open →Stuck tierPlatform Engineering — Emerging
Inconsistent observability + ownership across the estate makes incident response longer than it should be. Three moves on the platform side.

DevSecOps is supply-chain
The supply-chain framing for SOCI / NIS2 / CIRCIA — why provenance + signing + SBOM-loops are now the conversation.
Open →EssayPlatform engineering is the AI moat
The substrate argument that applies equally to OT-adjacent operators: inherited capabilities compound; bolted-on capabilities don’t.

Board-ready briefing — critical infrastructure section.
Open →Common anti-patterns in critical infrastructure.
The named failure modes that show up most across critical infrastructure engagements. The catalogue has all 15; these four are the ones that recur here.
Vault Theatre
Static creds in IT estates that bridge to OT. The audit triggers for SOCI ML2-equivalent maturity.
Open →Anti-patternSBOM Shelfware
NIS2 + CIRCIA expect the loop, not just the artefact, when reporting incidents.
Open →Anti-patternPDF Principles
Encoded principles are what survives the 3am incident; documented ones aren’t.
Open →Anti-patternKPI Cargo Cult
Reliability metrics presented without policy consequences are reporting theatre, not resilience.
Open →Working on this in Critical Infrastructure?
If you’re responding to SOCI / NIS2 / CIRCIA obligations, hardening IT-OT integration points, or rebuilding the SRE programme behind a critical-service SLA — I run focused engagements with the architecture / platform / security partners that own this work.
