What We See. What We Do About It.

Seeing what’s exposed means nothing without a framework to assess, report and act on it. We do both — most firms do only one.

Priorities grouped by tier — BlackFlag Advisory’s 2026 editorial view.

External intelligence, translated into governance you can act on.

Discretion Isn’t a Marketing Position.
It’s How We Operate.

Confidentiality by Design

No client names, no logos. Every engagement is treated with the same confidentiality we assess others against — for a firm that evaluates privacy, practising what we preach isn’t optional.

Across Every Sector

Healthcare, finance, government and retail — listed and private, regulated and emerging. The exposure patterns repeat; only the obligations differ.

White-Label Ready

Findings delivered under your brand through established law-firm and insurance partnerships — your advisory, our engine.

Our findings speak for themselves. Our clients don’t have to.

What Is Exposed About Your
Organisation Right Now

Using exclusively passive, publicly available data sources — no systems accessed, no active scanning — we surface what anyone with the right knowledge can already see about your organisation.

All findings mapped to ASD Essential Eight · NIST CSF 2.0 · ISO 27001 · APRA CPS 234 · Privacy Act 1988

Your External Attack Surface

Domains, subdomains, exposed services, and infrastructure visible to the public internet — including assets you may not know exist.

Your Technology Stack

The software, platforms, CMS, CRM, and third-party integrations on your public-facing systems — and whether they carry known vulnerabilities.

Your Email Security Posture

Whether your domains are protected against phishing and spoofing — missing email security records leave your brand open to impersonation.

Your SSL/TLS Configuration

The strength of your encryption, certificate validity, cipher suite weaknesses, and whether your systems meet current compliance thresholds.

Your Credential Exposure

Whether your organisation's domains appear in known public breach databases — indicating compromised credentials that may still be in active use.

Your Compliance Gaps

Observable gaps in your privacy policy, data collection practices, and vendor relationships creating regulatory exposure under the Australian Privacy Act.

What We Deliver

Structured, evidence-based GRC advisory for organisations operating in complex, regulated environments across Australia and Asia-Pacific. Every engagement is disciplined, documented, and mapped to recognised frameworks.

Threat Intelligence & GRC

Every Firm Left a Door Open

As Tranche 2 made Australia’s law firms custodians of seven years of client identity data, we looked at 20 of them exactly as an attacker would — from the outside, touching nothing. 15 of 20 already had staff logins in criminal hands, and not one came through clean.

Cryptography & Quantum Risk

Minutes, Not Decades: The Quantum Deadline on Your Cryptography

A cryptographically-relevant quantum computer does not exist yet — but ASD wants RSA and ECC retired by 2030, and harvest-now-decrypt-later is already underway. What quantum actually breaks, who holds the hardware, and the GRC steps to start now.

Nation-State & Critical Infrastructure

Router Hygiene as National Defence

On 13 July 2026 the ASD co-signed a joint advisory attributing a decade-long critical-infrastructure campaign to Russia’s FSB Center 16. The doorway is not a zero-day — it is default router passwords. The attack path, and the GRC controls that close it.

Third-Party Risk & OSINT

Your Exposure Sits Outside Your Walls

EY and Lidl were breached weeks apart in July 2026 — neither inside its own walls. With Klue, Salesloft Drift, Aura and Canvas, the 2026 record points to one blind spot: the third party, and the process nobody owned.

Threat Intelligence & GRC

ASD Just Made Your External Exposure a Board Obligation

In six months ASD doubled the ISM’s Govern function — moving your systems, your suppliers and your people into the function where the board is accountable. None of it can be evidenced from inside your network, and the Essential Eight measures none of it. A control-level comparison of the December 2025 and June 2026 releases.

Threat Intelligence & GRC

ASD Now Requires You to Be Independently Assessed

ISM-2118 is new in June 2026: vulnerability assessments and penetration tests before deployment, before significant change, and at least annually. Self-attestation stopped being enough — and the control carries no Essential Eight mapping, so no maturity score has ever measured it.

ASD ISM Update, June 2026.
Every principle and control, compared. →

ASD publishes the Information security manual as a PDF. It also publishes it as a spreadsheet — and almost nobody compares one release against the last. We did, control by control. The Govern function doubled, twenty-nine controls were added, one was removed, and not one of June’s twenty new controls maps to the Essential Eight. The full comparison is published free, so you can check the arithmetic yourself.
