Somewhere in your organisation right now, staff are using mobile apps to communicate with clients, process information, manage schedules, and handle data that is almost certainly subject to the Australian Privacy Act. Some of those apps were approved by IT. Many were not. Almost none of them were assessed for what they actually do with the data they collect.
This is not a theoretical risk. It is a live, observable exposure that most Australian organisations carry without any awareness of its scope — and without any ability to manage it. The apps are running. The data is moving. And the organisation has, in most cases, made no documented decision about whether any of it is acceptable.
What makes this particularly significant is that it is not necessary to hack an app, access a server, or conduct any active testing to understand what it is doing. The information is publicly available. The permissions it requests are listed in the app store. The trackers it embeds are catalogued in public databases. The data it transfers across borders is disclosed — inconsistently — in its privacy policy. A structured passive assessment can surface what an app is doing with your organisation's data before that data ever leaves a device.

The Scale of the Problem Australian Organisations Are Not Measuring
The average employee uses between eight and twelve apps in the course of their working day. Most of those apps were designed for consumer use and retrofitted into enterprise environments without meaningful security or privacy evaluation. They request permissions that exceed what their stated function requires. They embed advertising and analytics SDKs that transmit behavioural data to third parties. They store data in jurisdictions that Australian privacy law requires to be disclosed and, in many cases, consented to.
The Privacy and Other Legislation Amendment Act 2024 — the most significant reform to Australian privacy law since 1988 — has sharpened these obligations considerably. The December 2024 amendments introduced enhanced security requirements, stricter notification obligations, and significantly increased penalties. An organisation that cannot demonstrate reasonable steps to assess the privacy posture of the apps its staff use is carrying regulatory exposure that is no longer theoretical.
The OAIC has been explicit. Mobile applications that collect personal information are subject to the Australian Privacy Principles. The obligation to take reasonable steps to protect that information extends to the tools through which it is collected and processed. An organisation that has never assessed the apps its staff use has not taken reasonable steps. The question is not whether the obligation exists — it is whether the organisation has any visibility into whether it is meeting it.
What Passive Assessment Reveals Without Touching a System
The most significant misconception about mobile app risk assessment is that it requires technical access to the app, its code, or its backend infrastructure. It does not. A structured passive assessment using publicly available data sources can surface the majority of material GRC risks associated with a mobile application before any system is accessed or any active testing is performed.
App store permissions disclosures are the starting point. Both the Apple App Store and Google Play Store require developers to publish what permissions their app requests and what data it collects. These disclosures are publicly available and represent a legally significant statement by the developer about what the app does. Comparing these disclosures against what the app's stated function actually requires is one of the most effective ways to identify excessive data collection.
Tracker and SDK analysis goes further. Independent platforms such as Exodus Privacy maintain catalogues of known advertising, analytics, and data collection trackers embedded in mobile applications. These trackers are detectable from publicly available app data without running the app or accessing any system. An app that embeds twelve advertising SDKs and requests access to device contacts, microphone, and precise location — when its stated purpose is project management — is exhibiting a permissions and tracker profile that warrants scrutiny.
Privacy policy analysis against the Australian Privacy Principles reveals whether the developer is meeting their disclosure obligations — and by extension, whether your organisation's reliance on that app is creating compliance exposure. APP 1 requires a clearly expressed and up-to-date privacy policy. APP 5 requires notification of collection. APP 8 requires disclosure of cross-border transfers. The majority of consumer apps used in enterprise environments fail at least one of these when assessed against Australian legal standards.
Developer intelligence contextualises the risk. An app developed by an entity with obscured ownership, registered in a jurisdiction with no meaningful privacy enforcement, and with no disclosed security practices, presents a different risk profile than one from a well-governed developer with transparent practices. This information is available through company registries, WHOIS records, and public corporate databases without any system access.
The Five Phases of a BlackFlag Advisory Mobile App Assessment
Every BlackFlag Advisory mobile app GRC assessment follows the same structured, evidence-based process. No systems are accessed. No active scanning is performed. Every finding is sourced, evidenced, and mapped to a recognised framework control.
Phase 1 — App Store & Permission Intelligence
We begin with what the developer has publicly disclosed. This includes the full permissions profile from both major app stores, Apple's Privacy Nutrition Labels, Google's Data Safety declarations, the developer's published data practices, and the app's update and maintenance history. We compare the permissions profile against the app's stated function to identify where collection exceeds what the purpose requires.
Phase 2 — Tracker & SDK Analysis
Using independent tracker databases and SDK analysis platforms, we identify every known advertising, analytics, location, and behavioural tracking SDK embedded in the application. Each tracker is assessed for its data collection purpose, the third parties it transmits data to, and whether those third parties are disclosed in the developer's privacy policy. SDK findings are cross-referenced against known data broker relationships and jurisdictional risk.
Phase 3 — Developer & Corporate Intelligence
We assess the developer entity using publicly available corporate records, registration databases, breach history, and regulatory action records. This includes identifying the jurisdiction of incorporation, any disclosed ownership structures, the developer's own security posture as observable from public sources, and any history of privacy complaints, data breaches, or regulatory findings.
Phase 4 — Compliance Review Against Australian Privacy Principles
We assess the app's publicly observable compliance posture against each of the 13 Australian Privacy Principles. This includes analysis of the privacy policy against APP 1 requirements, assessment of collection notification practices against APP 5, review of cross-border transfer disclosures against APP 8, and assessment of security practice disclosures against APP 11. Where the app's privacy policy is inconsistent with its disclosed data practices, that inconsistency is documented as a finding.
Phase 5 — Vulnerability & Known Threat Intelligence
We cross-reference identified app components and SDKs against the NIST National Vulnerability Database, the CISA Known Exploited Vulnerabilities catalog, and current threat advisories. Where the app or its components carry known exploited vulnerabilities that are publicly documented, those findings are included in the risk register with current threat context.
Who This Assessment Is For
The BlackFlag Advisory passive mobile app GRC assessment is designed for two distinct use cases. The first is organisations that want to assess the apps their own staff use — whether as part of a BYOD policy review, a broader GRC programme, or in response to a specific concern about a particular application. The second is organisations that have developed a mobile app and want an independent assessment of its compliance posture before launch or as part of an ongoing compliance programme.
For organisations reviewing apps their staff use, the assessment produces a clear picture of the compliance exposure created by each application in scope, the data flows that are occurring, and the remediation options available — which may include policy controls, application replacement, or vendor engagement.
For organisations that have developed their own app, the assessment provides an independent view of how the app's public-facing compliance posture will appear to regulators, sophisticated clients, and privacy advocates — before those audiences conduct their own review.
The Compliance Gap Most Organisations Are Carrying
The most consistent finding from mobile app assessments is not a single catastrophic issue. It is an accumulation of unmanaged decisions — apps approved without assessment, permissions accepted without scrutiny, privacy policies accepted without being read against Australian legal standards — that collectively create a compliance exposure the organisation has never quantified and cannot defend.
The standard the OAIC applies when assessing whether an organisation has taken reasonable steps to protect personal information is not whether a breach occurred. It is whether the organisation had processes in place that a reasonable organisation would have in place. An organisation that has never assessed the apps its staff use, that has no documented mobile app approval process, and that has no visibility into what data those apps are transmitting and to where, has not taken reasonable steps. That position is increasingly difficult to defend.
The passive mobile app GRC assessment exists to close that gap — to give organisations documented, evidenced visibility into their app-related compliance exposure, and a clear path to remediation. No systems are accessed. No active scanning is performed. The findings are based exclusively on what is publicly observable. And that, in itself, is the point: if it is observable to us from public sources, it is observable to a regulator, a litigant, or a threat actor who is looking.
