A software architecture audit is a structured review of a system's design against a fixed set of concerns — domain model, auth, multi-tenancy, API design, persistence, observability, deployment, and compliance. Done well, it maps every concern to concrete evidence, ranks the gaps by severity and business impact, and ends in a prioritized remediation plan.
This guide walks the method step by step — then shows the fastest way to get a first, evidence-backed result.

Architecture decisions compound. A missing tenant-isolation filter, an auth gap, or a compliance control deferred to "later" is cheap to fix while it's one decision and expensive once it's load-bearing across the codebase. An audit surfaces those gaps while they are still cheap to close.
Audits also serve a second audience: a CTO evaluating a build, an auditor verifying controls, or an acquirer doing technical due diligence all want the same thing — an evidence-backed map of what the system does and does not have, not a verbal assurance that "it's fine." That is the difference between an opinion and an audit.
Five steps take you from raw artifacts to a remediation plan a stakeholder can act on.
Collect the artifacts that describe the system as it actually is: architecture diagrams, a README or design doc, the data model (ERD or migrations), the list of external integrations, and any compliance requirements. You are auditing the real system, so prefer current sources (the repo, the running schema) over stale wiki pages.
Decide what "good" means before you look. A defensible audit scores against a fixed set of concerns rather than gut feel: domain model coverage, authentication and authorization, multi-tenancy and data isolation, API design, persistence and migrations, observability, deployment and CI/CD, and the compliance controls relevant to your industry (SOC 2, ISO 27001, GDPR, HIPAA, PCI-DSS, DORA, NIS2).
For every concern, find the artifact that satisfies it — the route file that enforces auth, the migration that adds the tenant column, the control that writes the audit log. A concern with no evidence is a gap, not a "probably fine." This traceability map is what turns an opinion into an audit you can hand to a CTO or an auditor.
Sort the gaps by what they cost you if left unaddressed: a missing tenant-isolation filter is a data-leak risk (critical); a missing forgot-password flow is a launch blocker (high); inconsistent API error shapes are tech debt (medium). Severity plus business impact — not the order you happened to find them — drives the roadmap.
Close the loop with a prioritized roadmap: what to fix now, next, and later, with the rationale for each phase. An audit that ends in a ranked list of findings is half an audit; the deliverable a stakeholder acts on ends in a sequenced plan.
Most audits surface the same recurring gaps. Knowing them in advance makes your review faster and your roadmap sharper.
Queries that run without an organization or workspace filter — the single most common source of cross-tenant data leaks in multi-tenant SaaS.
Endpoints that skip the authentication or authorization check, or auth flows missing entirely (forgot-password, email verification, session expiry).
A data model that drifted from its migration history, so the running database and the source of truth disagree.
Audit logging, encryption at rest, and access controls treated as a later checklist rather than wired into the architecture — expensive to retrofit under a SOC 2 or HIPAA deadline.
No structured logging, health checks, or error tracking — the system is unobservable in production until something breaks.
External dependencies (payment, email, identity) with no fallback or failure handling, so an upstream outage takes the whole product down.
Each approach has a place. The right one depends on how fast you need a result, your budget, and whether you need to re-run the audit as the system changes.
The automated audit is a strong first pass — it tells you where to spend deeper manual or consultancy time, and it's repeatable as your architecture evolves.
Upload your architecture docs (PDF, Word, Markdown, or HTML) and get back a traceability report scored across architecture concerns — what can be auto-generated, what's partial, what cannot, and what needs custom work. Free for the first audit, no signup, and the report URL is shareable.
Need a human in the loop? The Architect plan pairs the automated audit with a dedicated solution architect for compliance-heavy builds.
A software architecture audit is a structured review of a system’s design against a fixed set of concerns — domain model, authentication and authorization, multi-tenancy and data isolation, API design, persistence, observability, deployment, and the relevant compliance controls. Instead of a subjective opinion, it produces a traceability map that ties each concern to the evidence that satisfies it (or flags it as a gap), ranked by severity and business impact, and ending in a prioritized remediation plan.
First, gather the real architecture inputs (diagrams, design docs, the data model, integrations, compliance requirements). Second, fix the set of concerns you will score against before you look. Third, map each concern to concrete evidence in the system — a concern with no evidence is a gap. Fourth, rank the gaps by severity and business impact. Fifth, turn the ranked findings into a phased remediation roadmap of what to fix now, next, and later.
The recurring ones are missing or partial tenant isolation (queries without an organization or workspace filter), auth gaps on protected routes and missing auth flows, a schema that has drifted from its migrations, compliance controls bolted on later rather than wired in by construction, thin observability (no structured logging or health checks), and undocumented coupling to external integrations with no failure handling.
A manual review by a senior engineer is cheap to start but pulls them off delivery and varies with the reviewer. A top-firm consultancy applies a rigorous methodology but takes weeks and costs tens of thousands of dollars. An automated audit returns a deterministic, evidence-mapped report in seconds and is repeatable as the architecture evolves — a strong first pass that tells you where to spend deeper manual or consultancy time. Many teams use the automated audit to scope the engagement, not replace human judgement entirely.
Yes. Archiet’s instant architecture audit is free for the first audit and needs no signup: you upload your architecture docs (PDF, Word, Markdown, or HTML) and get back a traceability report scored across architecture concerns, with a percentage breakdown of what can be auto-generated, what is partial, what cannot, and what needs custom work. The report URL is shareable, so you can forward it to your team. Run it at archiet.com/audit-my-architecture.
