When it comes to cybersecurity compliance for Australian government and critical-infrastructure systems, choosing the right IRAP Assessor is a business-critical decision.
If you make a mistake, you may have to spend months (and hundreds of thousands of dollars) chasing rework and red tape.
If you do it correctly, you’ll gain access to new government contracts, strengthen your security posture, and expedite accreditation.
From Cisco’s technical solutions to Thomson Reuters’ consumer systems to Airservices Australia’s PROTECTED cloud platform, we at ARANKISH have finished dozens of IRAP assessments for cloud and SaaS environments.
This guide lists the top IRAP assessors in Australia, explains what sets them apart, and helps you choose the one best suited to your organisation.
What Does an IRAP Assessor Actually Do?
The Australian Signals Directorate (ASD) oversees the Information Security Registered Assessors Program (IRAP), which certifies experts to assess ICT systems in accordance with the Information Security Manual (ISM).
An IRAP assessment determines whether your system meets the security controls required for handling data classified as OFFICIAL, OFFICIAL: Sensitive, or PROTECTED.
Typical process:
- Plan and prepare
- Define the assessment boundary
- Assess the controls
- Produce the IRAP assessment report
For SaaS and cloud-hosted solutions, this often includes multi-platform environments (AWS, Azure, GCP) and third-party integrations — areas where ARANKISH specialises.
How We Evaluated the Best IRAP Assessors
We compared each firm across five key factors:
| Evaluation Criterion | Why It Matters |
|---|---|
| Depth of IRAP experience | Direct familiarity with ASD, ISM updates, and assessment methodology. |
| Cloud and SaaS expertise | Ability to assess complex multi-cloud environments efficiently. |
| Client industries | Proven results in government, SaaS, finance, or public safety sectors. |
| Speed and communication | Shorter turnaround times and practical remediation guidance. |
| Pricing transparency | Predictable cost estimates and clear deliverables. |
