Why now

The gap between finding a flaw and exploiting it is shrinking to hours.

Home Affairs says frontier AI is cutting the time between discovering a vulnerability and exploiting it from days to hours, and has warned of a “vulnerability storm”. Here is 2026 so far.

for one researcher using AI to turn long-standing PHP flaws into working exploits. Researchers say the same work would otherwise take a team months.

Products

Three products. Fixed scope, fixed price.

Each one runs on the same tooling, playbook and templates, and maps to the framework you report against. Each one ends with working fixes as well as a report.

Pricing

Every product is fixed-price, so you know the cost before we start. For Commonwealth buyers, each product’s total contract value is scoped to stay under the $125,000 (GST inclusive) procurement threshold, where there’s no open tender requirement and the rules ask agencies to prioritise Australian businesses.

Obligations

Choose your sector to see the obligations that apply and where each product fits.

PSPF Direction 002-2026 has two deadlines, and fewer working days than the calendar suggests.

It applies to every non-corporate Commonwealth entity. Home Affairs says legacy systems with unpatched vulnerabilities now pose an “unacceptable risk to Australian Government operations”.

Readiness check

Seven questions. Two minutes.

Answer for your organisation to see where the gaps are and which product fits. Nothing you enter leaves this page.

Do you have a current list of every system you run, with an owner for each?

Every legacy plan starts with a stocktake, including the one Direction 002 requires.

Do you know which of those systems are out of vendor support?

Unsupported systems don’t get patches when the next flaw lands.

Do you have a plan, with a target, for retiring or protecting out-of-support systems?

Commonwealth entities owe Home Affairs one by 31 March 2027.

Could you patch a vendor-rated critical flaw on internet-facing systems within 48 hours?

The Essential Eight expects 48 hours when a flaw is critical or a working exploit exists.

When PHP2Shell was disclosed, did you know within a day which of your systems were exposed?

Exploit attempts were recorded four days before the patch.

Has anyone tested what an AI agent could reach on your public-facing systems?

An AI agent on a research task reached non-public files on a Medicare statistics portal.

Is your custom-built software security reviewed before each release?

AI-assisted review can now cover an entire codebase quickly.

How we work

Authorised, verified, fixed.

  1. Scope and authorise

    Written rules of engagement before anything runs: what’s in scope, when we test and who to call. We start in non-production wherever it exists.

  2. Find

    AI agents and AI-assisted code review work through your systems far faster than manual testing. A person verifies every finding before it reaches you.

  3. Fix

    We write fixes as merge-ready changes, or document a mitigation where a fix has to wait. Your team reviews and deploys.

  4. Hand over

    You get an evidence pack and an executive briefing, plus the artefacts your framework or regulator asks for.

Your code stays with you

We run analysis inside your environment or on tools you’ve already approved. Nothing leaves without your sign-off.

Mapped to your framework

We map findings and plans to the framework you report against, whether that’s the Essential Eight, the ISM and PSPF, your SOCI program or ISO/IEC 27001.

Australian-owned and cleared

An Australian-owned SME with cleared personnel and hands-on experience building and running Commonwealth platforms.
