Introduction
The first question almost every SaaS founder or CISO asks is: what is this going to cost? It's a reasonable question, and the honest answer is that ISO 27001 certification in Australia varies significantly depending on who you hire, how you approach the process, and the complexity of your environment.
This guide breaks down the real costs — not the marketing copy version.
What You're Actually Paying For
ISO 27001 certification involves two distinct cost streams that are often conflated:
- Consultancy or implementation costs — what you pay someone to help you build and document your Information Security Management System (ISMS)
- Certification body fees — what you pay an accredited third-party auditor to formally certify your ISMS
Both are mandatory. You cannot self-certify ISO 27001.
Consultancy Costs in Australia: What to Expect
Gap Assessment Only
A standalone gap assessment — which reviews your current controls against every ISO 27001:2022 clause and all 93 Annex A requirements — typically costs between $2,000 and $5,000 AUD from a specialist boutique consultancy.
Be cautious of assessments priced significantly below this. A genuine gap assessment takes time: reviewing your environment, interviewing stakeholders, testing controls, and producing a written report with a prioritised remediation roadmap. A $500 "online questionnaire" is not a gap assessment.
Full ISMS Implementation
End-to-end implementation — from gap assessment through to certification-ready ISMS — typically costs between $10,000 and $30,000 AUD from a specialist consultancy, depending on:
- Organisation size: A 15-person SaaS company is simpler than a 200-person managed service provider
- Scope: Are you certifying the whole business, or a specific product or service?
- Current maturity: A company with existing security controls and documentation will require less remediation than one starting from scratch
- Consultant model: Working directly with a senior consultant (as VicByte operates) is more efficient than a larger firm that delegates to junior staff
Automated Compliance Platforms
Platforms like Vanta, Drata, and Sprinto charge between $1,000 and $2,500 AUD per month. They automate evidence collection and provide policy templates, which is genuinely useful — but they are not a replacement for experienced consultancy.
These platforms work well for relatively standard SaaS environments with common cloud infrastructure. They are less effective for companies with complex or unusual control environments, and they will not prepare you for the nuanced questions an auditor will ask during a Stage 1 or Stage 2 audit.
Certification Body Fees
Once your ISMS is implementation-ready, you engage an accredited certification body (BSI, Bureau Veritas, SGS, and others operate in Australia) to conduct a two-stage audit.
Typical certification body fees in Australia:
- Stage 1 audit (documentation review): $1,500 – $3,000
- Stage 2 audit (implementation audit): $2,500 – $6,000
- Annual surveillance audits (year 2 and year 3): $1,500 – $3,500 per year
- Recertification audit (year 3): Similar to initial Stage 2 cost
Total certification body investment over a three-year certification cycle: $8,000 – $18,000 AUD.
Hidden Costs Most Budgets Miss
Internal time: Your team will need to contribute. Policy review, evidence gathering, risk workshops, and audit preparation all require internal effort. For a 20-person company, expect 40–80 hours of internal time across the engagement.
Technical remediation: The gap assessment will identify control gaps that need fixing. Depending on findings, this might mean new security tooling, configuration changes, or process redesign. Budget 10–20% of consultancy costs for remediation work.
Certification body liaison: Some consultancies (VicByte included) include certification body selection and liaison in their scope. Others charge separately for this, or leave it entirely to you.
Why Cheapest Is Rarely Safest
ISO 27001 certification from a reputable body carries commercial weight precisely because the standard is audited seriously. A poorly implemented ISMS — one built from generic templates rather than your actual environment — will fail scrutiny during the audit, or worse, create a false sense of security.
The question to ask any potential consultant is not what do you charge? but what do you deliver, and can I speak to a client who went through the audit?
What VicByte Costs
VicByte's services are priced transparently:
- Gap Assessment: From $2,000 AUD (1–2 weeks)
- ISMS Implementation: From $10,000 AUD (3–6 months)
- ISMS Maintenance Retainer: From $750/month after certification
All engagements are scoped before any work begins. No surprises.

The best first step is a gap assessment. It tells you exactly where you stand, what needs to change, and what a realistic implementation will cost for your specific environment — before you commit to anything.
