Audits & Certifications

Standards-anchored validation by senior auditors.

Audits & Certifications is the body of work that validates designed and built infrastructure against recognized standards. We audit against TIA-942, EN 50600, ASHRAE, and the ISO management system standards. Our auditors are senior practitioners who have run the facilities they now audit, designed the systems they now assess, and certified the standards they now apply.

What we audit, against what.

Audits & Certifications is concerned with the validation of infrastructure against recognized standards. The pillar covers facility audits (TIA-942, EN 50600), operational readiness audits, threat and vulnerability risk assessments, environmental audits, power-quality audits, and AI infrastructure readiness assessments grounded in the AI Infrastructure Readiness Index.

The pillar operates at Layer 03 of the Mission-Critical Assurance Stack — the certification layer. It validates work that has been done at Layer 02 (Design) and surfaces the implications for work that will be done at Layer 04 (Operations). The audit is the point-in-time judgement against the standard. The discipline that turns the certification into reliably operated infrastructure is conducted in the Operations & Governance pillar.

What the pillar covers: validation against the standard, against the operational state, and against the risk profile specific to the facility. What the pillar does not cover: the design or engineering work being audited, the construction itself, or the day-to-day operation of the facility once certified.

Standards are foundational. AIRI and our other frameworks are read alongside them — never in place of them. A facility certified to TIA-942 may still score AIRI Level 01 if no AI-specific work has been done. The certifications and the AIRI score describe different things.

Engagement model

Four stages.

Every audit engagement runs through the same four stages, scaled to the standard being audited and the scope of the facility or program.

Scoping conversation

A 30-minute working session that establishes the audit type, the standard or framework being applied, the scope, and the timeline. We confirm whether the audit type we offer is the right fit.

Audit plan and structure

A documented audit plan with defined scope, timeline, onsite duration, document requirements, and fees. Audit plans are agreed before the work begins.

Audit conduct

Onsite audit work, document review, interviews, observed procedures, and sampled testing as the standard requires. Senior auditors lead the work. Findings are documented as the audit proceeds.

Findings and certification

A documented audit report with findings, observations, and certification where applicable. A presentation to the relevant audience. A defined follow-through period during which we remain accessible.

Services

What we audit.

The Audits & Certifications pillar comprises seven engagement types. Each is conducted by senior auditors against the relevant standard or framework,
with audit findings, remediation roadmap, and certification (where applicable) delivered as a defined output.

Data Center Facility Audits

Audits against TIA-942 and EN 50600 for data center facilities at every Tier and class.

Operational Readiness Audits

Audits of operational state — procedures, runbooks, governance, and execution — against the operating model the facility purpose requires.

AI Infrastructure Readiness Assessments

AIRI-grounded assessments of AI infrastructure readiness across power, thermal, network fabric, sovereignty, and operational dimensions.

Threat & Vulnerability Risk Assessments

TVRA conducted to the standard required by sovereign and high-security operators. Physical, cyber-physical, and operational threat surface.

Environmental Audits

Environmental audits aligned with ISO 14001 and operator-specific sustainability commitments.

Power Quality Audits

Power quality audits assessing the integrity, stability, and resilience of the facility electrical envelope.

Standards

What we audit against.

Audit work is anchored entirely in the standards canon. The standards are not the InfraSentry contribution; they are the bedrock against which our work is conducted. The InfraSentry contribution is the discipline of senior practitioner audit conduct, the consistency of audit posture across geographies, and the integration of facility audits with the broader assurance fabric.

TIA-942 is the Telecommunications Industry Association standard for telecommunications infrastructure for data centers. EN 50600 is the CENELEC standard for information technology facility infrastructure. Both define the canonical design and infrastructure requirements at every Tier and class. We audit against both.

ASHRAE TC 9.9 sets the thermal envelope standards for IT equipment environments. ISO 22301, ISO 27001, ISO 31000, and ISO 14001 anchor business continuity, security, risk, and environmental dimensions.

InfraSentry frameworks are read alongside the standards, never in place of them. The AI Infrastructure Readiness Index addresses AI-specific dimensions — GPU density, liquid cooling readiness, gigawatt-scale procurement, sovereign workload governance — that the foundational standards were not scoped to address. AIRI assessments are conducted as Layer 03 audits in their own right; they do not substitute for, replace, or weaken the facility audits anchored in the canonical standards.
