5 Quick Wins for ISO 27001 Readiness

ISO 27001 can seem daunting, but it doesn’t need to start that way. Every successful Information Security Management System (ISMS) begins with a few disciplined, achievable steps that demonstrate progress and build internal confidence.

These five quick wins help you prove maturity early, engage stakeholders, and prepare clean evidence for your eventual audit—without bureaucracy or burnout.

1️⃣ Define Your ISMS Scope Clearly

What it means: Decide exactly what’s in and out of scope—locations, systems, products, and people.
Why it matters: A clear boundary prevents endless debates and reassures auditors your ISMS is deliberate, not accidental.

💡 Tip: Phrase your scope in business terms (“Our SaaS platform hosted in AWS Sydney serving Australian healthcare providers”)—not just IT systems.

2️⃣ Choose a Risk Methodology That Works

Don’t chase academic perfection. A simple likelihood × impact matrix or heatmap is enough at first. What matters is that everyone understands and applies it consistently.

✅ Outcome: A shared language for decision-making—linking security priorities to business risk appetite.

3️⃣ Build a Living Risk Register

Start with your top 5 security risks today—no massive spreadsheet needed.
For each, capture: description, owner, likelihood, impact, and current mitigation.
Update quarterly to show a functioning risk cycle.

⚙️ Pro Tip: Store your register in SharePoint or Confluence—versioned, owned, and reviewable. That’s instant audit evidence.

4️⃣ Map Current Controls to Annex A

Control Area	Example Evidence
Access Control	Entra ID roles, MFA reports, Joiner-Mover-Leaver logs
Asset Management	Endpoint inventories, MDM policies, classification register
Business Continuity	Backup tests, RTO/RPO targets, DR results
Awareness & Training	Security 101 completion rates, phishing sim stats

Mapping existing controls first avoids reinventing the wheel and highlights where investment truly matters.

5️⃣ Book Your First Internal Audit

Even if informal, an internal audit creates momentum. It exposes blind spots, builds familiarity with audit language, and demonstrates leadership commitment.

🧭 Goal: Treat your first audit as a rehearsal—practice how evidence is presented, who speaks to which controls, and where your ISMS still feels manual.

Why These Steps Matter

Each action creates measurable progress, confidence, and evidence:

Scope clarity — proves organisational boundaries.
Risk methodology — shows decision structure.
Register updates — demonstrates continuous management.
Control mapping — connects business reality to Annex A.
Internal audit — validates everything in practice.

🎯 Bottom line: You don’t need perfection to start ISO 27001—you just need progress that’s traceable, reviewable, and repeatable.
