Enterprise Governance Meets Technical Precision
Erbium Cyber is an Australian advisory firm providing on-demand security leadership to support your existing team. We help organizations make clear cyber decisions, protect operations, and meet compliance standards.
Strategy Meets Hands-On Defense
We link executive planning with practical IT controls. From the ACSC Essential Eight and SOCI regulations to Microsoft 365 security and supplier risk, we ensure leadership goals match real-world defense.
Independent and Practical
We take no commissions from software vendors. Instead of pushing new tools, we optimize the systems you already own and replace dense audit binders with simple 30, 60, and 90-day action plans.
100% Australian-Based
Our team and data stay entirely within Australia. We never send telemetry offshore and permanently purge project data after 60 days to protect your privacy.
Enterprise Cyber Defense. Scaled to Your Velocity.
Principal-led, vendor-neutral cyber advisory for Australian organisations that require robust governance, frontline defense, and sovereign assurance—without the overhead of a full-time CISO payroll.
Cyber Readiness Snapshot
Delivering principal-led, vendor-neutral cyber advisory for Australian enterprises and SMEs that need defensible governance, frontline technical defense, and sovereign assurance—scaled to your velocity without permanent executive overhead.
Governance & Risk Review
Accelerate procurement approvals and satisfy regulatory mandates with a 30-day governance and risk sprint. We benchmark your posture against ISO 27001, SOCI obligations, and enterprise tender gates, translating gaps into practical 30/60/90-day task sprints. Gain defensible control evidence, CIRMP planning, and board-level risk priorities that unlock major contracts without disrupting delivery.
Security Executive Advisory
Access senior enterprise security leadership tailored to your organisation's scale and operational pace. Our Cyber Security advisory augments your executive team, aligning whole-of-enterprise governance with frontline technical precision to deliver clear board risk quantification, effective steering committees, and confident contract de-risking.
Backed by 100% sovereign Australian advisory, our retainers combine strategic policy with active incident triage and practical frontline defense to protect your operations and reputation.
Proof in the posture: clear, defensible cyber outcomes
Essential Eight readiness snapshot
A concise, anonymized view of how a five-day assessment turns Essential Eight exposure into a Red/Amber/Green heatmap, ranked priorities, and practical quick wins. No real telemetry or client information is shown.
30/60/90-day governance roadmap
A practical implementation view connecting governance findings to sequenced actions, accountable owners, and measurable milestones. Designed to support tender, ISO 27001, and SOCI readiness without slowing operational delivery.
Board-level cyber risk dashboard
An executive reporting concept that translates technical exposure into quantified business risk, decision points, and trends. It demonstrates how a fractional CISO can make security steering committees more actionable.
Sovereign assurance and vendor risk
A visual representation of vendor-neutral review and Australian data-residency assurance, including onshore advisory and a 60-day cryptographic purge commitment. Examples are illustrative and reveal no vendors, telemetry, or confidential client data.
