SaaS vendors pursuing IRAP certification commonly stumble on five patterns that extend timelines and derail expectations.
The first misconception is straightforward: a certified cloud infrastructure does not certify the application sitting on top. When a vendor deploys onto a PROTECTED-rated IaaS, that endorsement applies to the cloud provider’s service offering for the workloads they have explicitly assessed. Your SaaS is a separate system with its own security architecture, data flows, and control implementation. It requires its own ASD assessment from the ground up. Too many vendors discover this distinction only after committing six months to a timeline that assumes inheritance.
The second mistake conflates the Essential Eight with the ISM itself. The Essential Eight represents a practical starting point for cyber hygiene, but the ISM covers a much broader control landscape: cryptographic management, event logging, privilege brokering, change management, incident response workflows, and dozens of operational and architectural domains. Vendors who have treated E8 compliance as sufficient hit a sharp reality check during Stage 1 when the assessor’s control mapping reveals the actual scope.
Architecture designed without ISM control considerations creates lasting friction. When an SSP is authored after the system is built, the evidence mapping begins: which logs prove this control is implemented? Where is the key management policy documented? How are identity boundaries enforced? Retrofitting evidence for controls that were not designed in — particularly around event logging retention, cryptographic key lifecycle, and identity segregation — consumes far more effort than baking control requirements into the design from the start.
Many vendors reflexively choose Maturity Level 2 because a customer mentioned it. Often, ML1 scoped appropriately meets the customer’s actual need and is achievable within a realistic timeline. ML2 without foundational control hygiene creates a different problem: Stage 1 stalls, assessor engagement extends, and the vendor faces a costly reset. Scope conversations early, not late.
Finally, evidence collection is where most timelines slip. The report itself is straightforward; gathering configuration screenshots, policy excerpts, log samples, audit trails, and change records across the entire system is the labour. A typical IRAP submission involves dozens of artefacts per control. Vendors who underestimate this volume — treating it as an afterthought — find themselves scrambling to generate evidence months into the engagement.
The practical takeaway: begin with ISM control mapping before architecture is locked, scope Maturity Level against actual requirements, not aspirations, and budget evidence collection as the primary workstream, not the final phase.
