Questionnaires measure confidence. We measure posture.
Most cyber assessments ask your team how things are configured, then grade the answers. It is the watermelon problem: green outside, red inside. Vyfority inspects the environment itself, external scanning, configuration analysis and evidence review against the benchmark you choose, so your board sees what is true rather than what is reported.

The gap between the reported and the dashed outline is the material risk: what the dashboard claims versus what an inspection finds.
You can outsource the service. You can never outsource the risk.
Your business runs on other people's systems: cloud, SaaS, outsourced operations, and the suppliers behind those suppliers. Vyfority runs third and fourth-party risk as a managed service: a defensible register, proportionate assessments verified with OSINT scanning, and scheduled reassessment.

OSINT-Verified
Every response checked against external posture
Monthly
Scheduled reassessment, not a one-off survey
Most breaches aren't detected. They're announced.
By a ransom note, a journalist's call, or the AFP. Vyfority's compromise assessment answers the question before someone else does: passive scanning and digital forensics to determine whether a compromise is underway, contain it early if it is, and establish root cause.

Regulation is stacking up. Your framework shouldn't.
The 72-hour ransomware reporting clock, SOCI obligations, Privacy Act reform, APRA's prudential standards and its expectations on AI, the new Aged Care Act. Vyfority builds one governance framework mapped to controls and verified across the three lines of assurance.

Most mid-market security estates were never designed; they accreted. Vyfority's strategy and transformation practice applies antifragile principles and a threat-anchored playbook, turning the security budget from a black hole into a defensible investment with a measurable line to revenue protection.

New · Fixed-Fee Diagnostic
Your dashboard says green. We read what it is hiding.
The Posture Reality Check is a two-day, read-only diagnostic that proves the gap between your stated security policy and your actual technical reality. No agents, no exploitation, no disruption. Your board receives the stated-versus-actual table and the evidence behind it.

The Security Stack Cost Audit
Your security budget is larger than it needs to be.
Most mid-market security stacks carry $30,000 to $100,000 in redundant, underused or overpriced tooling, invisible to the CFO. One structured day identifies it and produces a prioritised Kill List, or the audit is free.

The Principal
Dean Kastelic, Founder
Throughout my career, I've led cyber uplift initiatives across some of Australia's most iconic organisations. Time and again, I saw the same challenge: the struggle to move from strategy to execution, and the difficulty of translating high-level plans into a comprehensive programme of work with clear, measurable deliverables. I've seen exactly why the Big 4 and traditional integrator models fail: they are built on junior leverage, endless scope expansion, and reporting theatre.
In response, I founded Vyfority and developed a playbook based on what actually works in the real world. The result: an advisor who can walk into a boardroom in days, deliver a finished product in weeks, and stand firmly behind the financial and operational outcome.
