Who it’s for
APRA-regulated entities (banks, insurers, superannuation funds) and their information-security teams.
What readiness means for APRA CPS 234
For CPS 234, readiness means each information-security requirement — including third-party and testing obligations — is evidenced to a standard that supports APRA supervisory review.
How Netallion handles it
Your APRA CPS 234 readiness journey
- 1
Scope entity & obligations
Confirm your standing as an APRA-regulated entity and scope the CPS 234 requirements — information-security capability, control implementation, testing, third-party and notification — that apply.
- 2
Map evidence to requirements
Attach the information-security policy, control-testing results and third-party assessments to the requirements they support, with ownership and review dates.
- 3
Assess evidence
Each requirement is assessed for whether the evidence demonstrates it in operation — testing performed at a frequency commensurate with the rate of change, incidents notified within APRA's timeframe — not merely a policy statement.
- 4
Surface blockers
Requirements with missing or stale evidence — testing that lags the rate of change, a third party without an assessed control posture — become explicit, ranked blockers.
- 5
Review & finalise
An authorised assessor reviews the determinations and pins a readiness posture that maps to APRA's own self-assessment structure; CPS 234 is subject to APRA supervisory assessment, not Netallion certification.

From the field
Common APRA CPS 234 blockers we find
Where evidence most often falls short — surfaced explicitly, not averaged away.
- Security testing is performed but not at a frequency commensurate with the rate of change in the environment, so recent changes are untested.
- A third party manages an information asset but there is no evidence its security capability was assessed.
- Information assets are catalogued but not classified by criticality, so control strength cannot be shown to match sensitivity.
- Incidents are recorded internally but there is no evidence they were notified to APRA within the required timeframe.
Evidence
The evidence you'll bring

- board & senior-management oversight records
- roles & responsibilities
- information-security capability assessment
Control implementation
- control catalogue mapped to information-asset criticality
- hardening & access-control evidence
- classification of information assets
Third-party
- third-party information-security assessments
- assurance over providers that manage information assets
- contractual security obligations
Testing & incidents
- control-testing programme & results
- test-frequency rationale against rate of change
- incident-notification records to APRA
- board reporting on testing outcomes

CPS 234 readiness self-assessment
Answer a short set of questions to see an indicative CPS 234 readiness posture — no sign-up.
Are there specific individuals or teams (e.g., CISO, SecOps) formally assigned to manage security?
Is there a budget and headcount allocated for security tools, personnel, and training?
Is security a regular topic at board meetings, with clear metrics and risk reporting?
Do you have technical and procedural controls like MFA, firewalls, encryption, and access reviews in place?
Is there a scheduled process (e.g., quarterly, annually) to assess and update security controls?
Do you perform vulnerability scans, penetration tests, or red team exercises?
Has a third party (e.g., an external auditor) reviewed your security controls within the last 12-18 months?
Please answer all questions to calculate your score.

Cross-framework leverage
Evidence you assemble for one framework often supports another. Commonly paired with:
Readiness, not certification. Netallion provides evidence assurance and readiness assessment; it does not issue or guarantee any formal outcome. Where a framework has a formal certification, attestation, authorisation or conformity-assessment scheme, that outcome remains with the appropriately authorised third party or authority. CPS 234 compliance is subject to APRA supervisory assessment (including tripartite reviews); APRA is the authority, not Netallion. Where the boundary sits.
