Cyber Node Information

Cyber Node is a Perth-based cybersecurity consultancy. Every engagement is delivered by a senior practitioner. No junior layer, no automated scan rebadged as a penetration test, no offshore delivery on technical work. Reports are written for the people who have to act on them: boards, regulators, and insurers. What sets us apart is the depth behind the keyboard. Founder Matt Breuillac spent 15+ years as a chemical and process engineer inside world-scale industrial facilities, including Shell Prelude FLNG and the Albemarle Kemerton lithium refinery, before moving into cybersecurity. We assess OT environments as practitioners who have worked in them, not as IT testers who have read about them. We will not cause a process upset, and we know why that matters. What we do: Manual penetration testing. Web application, API, mobile, infrastructure, and Active Directory testing against a defined scope, performed by hand by a senior tester. Cloud security. Configuration and posture review across AWS and Microsoft 365, backed by AWS Security Specialty credentials. OT and IoT testing. ICS and SCADA-aware assessments, segmentation reviews, and AESCSF-aligned gap analysis for mining, energy, utilities, water, and SOCI-regulated operators. IEC 62443 zone-and-conduit thinking throughout. vCISO advisory. Security strategy, regulatory posture, risk reporting, and incident readiness for organisations without a full-time security executive. Cyber Exposure Snapshot (CES). A productised external attack surface scan from $399, sold as the first look before a manual engagement. We work to ACSC Essential Eight, ISO 27001, the SOCI Act, and AESCSF. Australian-owned, Australian-operated, with all data and findings kept inside Australian jurisdiction.
