Code Security Audit in Sydney.

Senior-led code security audit engagements across Sydney (NSW). Manual and tooled code review across your highest-risk repos — secrets, auth, injection, deserialisation and supply-chain risk, with CI integration that keeps findings from coming back.

85% of findings ship with a working patch suggestion — across Basalt operations in the past 12 months.

Threats facing Sydney finance.

The finance, fintech, media concentration around Sydney sees wire-transfer fraud, instant-payment abuse and identity-driven account takeover. Our code security audit work in NSW is scoped against this real threat profile, not a generic checklist.

Common pains

  • Tools that report thousands of low-quality findings
  • No clear ownership for fixing vulnerabilities in code
  • Supply-chain risk in third-party dependencies

How we engage.

  • Manual review of high-risk code paths
  • SAST + SCA integrated into CI with quality gates
  • Threat model per service or repository
  • Developer-grade fix guidance with sample patches

Reporting

Every finding ships with a control reference against ASD Essential Eight and SOCI Act, with ACSC guidance cited where it changes the remediation priority. Board reporting follows the APRA CPS 234 expectation set.

Local context.

Basalt delivers code security audit to organisations across Sydney and the wider NSW region (population ~5.4M). The finance, fintech, media sectors that anchor the region face a distinct threat profile — wire-transfer fraud, instant-payment abuse and identity-driven account takeover — and our engagements are scoped to that, not a generic playbook. Reporting maps cleanly to the ASD Essential Eight and SOCI Act that Australian boards already use, with regulator context (ACSC) called out where it changes a remediation priority.

Why Basalt for code security audit in Sydney.

Operator-grade

The team that scopes your work in Sydney is the team that runs it. The architects are the operators. Findings come from people who've actually exploited what they're describing — not desk research.

Australia threat fluency

Local context matters: wire-transfer fraud, instant-payment abuse and identity-driven account takeover. Basalt's Sydney engagements are scoped to the threat profile of finance teams in NSW, not a generic global checklist.

2026 attack surface

Where most regional providers are still testing for 2022 threat models, Basalt actively works agentic AI tool-abuse and indirect prompt injection at scale and identity-first attack chains across federated SaaS in production engagements. Forward-leaning, not theoretical.

What we test for.

  • Agentic AI tool-abuse and indirect prompt injection at scale
  • MCP server and AI-tool supply chain compromise
  • Post-quantum cryptographic readiness (NIST PQC migration)
  • Identity-first attack chains across federated SaaS
  • Open-source software supply chain (post-xz, post-tj-actions)

Cyber security in Australia can't be done with last year's threat models. The Basalt practice runs against current attacker tradecraft — agentic AI abuse, MCP and AI-tool supply chain, post-quantum readiness — alongside the legacy infrastructure work that still keeps most organisations awake at night.

Frequently asked questions.

How fast can Basalt start a code security audit engagement in Sydney?

Most Sydney engagements scope inside one week and start within two. Retainer clients can trigger work the same day. We do not pipeline Australian clients through junior teams — a senior consultant scopes and runs the work end-to-end.

Do you do code security audit on-site in Sydney or remote?

Both. Sensitive work — classified-adjacent environments, live incident response, OT walkthroughs — gets on-site time in Sydney and the wider NSW region. Routine assessments and detection engineering run remote with a tight feedback loop.

How does Basalt map findings to Australian regulators?

Every finding ships with a control reference against the ASD Essential Eight and SOCI Act so your compliance team is not re-mapping our report. Where ACSC guidance exists for the specific finding, we cite it inline. Board-level reporting follows the APRA CPS 234 expectation set.

What makes code security audit in Sydney different from a generic engagement?

The finance sector concentration in Sydney drives a different threat model than a generic Australian engagement — wire-transfer fraud, instant-payment abuse and identity-driven account takeover. Our scoping reflects that, and so does the test library we bring to the work.

Is Basalt set up for AI-era threats, not just legacy infrastructure?

Yes — this is core to how we work. Basalt actively researches and tests against agentic AI tool-abuse and indirect prompt injection at scale, MCP server and AI-tool supply chain compromise and identity-first attack chains across federated SaaS. Most regional providers haven't mapped these attack paths; we run them in production against client systems with explicit scope.
