About Mantilam

Senior-led, framework-aligned, built for enterprise.

Mantilam is an Australian cybersecurity consulting practice. We work with boards, CISOs, and delivery teams to translate cyber risk into deliberate, measurable action — across strategy, architecture, identity, cloud, operations, and resilience.

Our engagements are grounded in the frameworks that matter to regulated industries — NIST CSF, ISO 27001, Essential Eight, APRA CPS 234, PCI-DSS, SOC 2 — delivered by senior practitioners with 15+ years of enterprise and regulated-industry experience.

No theatre. No fear-mongering. Just clarity on what to protect, why it matters, and how to make it real — at a pace and scale your business can absorb.

Differentiation

Why leaders choose Mantilam.

Deep expertise, senior delivery, and framework fluency — built for enterprises where security maturity is measured by regulators, boards, and customers alike.

I

Framework-Aligned by Default

Grounded in NIST CSF, ISO 27001, Essential Eight, APRA CPS 234, and PCI-DSS. Your security maturity is demonstrable to regulators, auditors, and customers using the language they already speak.

II

Senior Practitioners, Every Engagement

No junior-led delivery, no inflated teams. Every engagement is led by a practitioner with 15+ years of enterprise security experience and direct exposure to regulated-industry programmes.

III

Outcome-Led, Not Hour-Led

Every engagement begins with a decision to be made. We measure success by the clarity of the findings and the actionability of the roadmap — not by the length of the report or the hours booked against it.

IV

Business-First Security

Controls proportionate to risk, roadmaps proportionate to capacity. We meet organisations where they are and take them where they need to be — without breaking what already works.

V

APAC-Native, Globally Fluent

Based in Australia with deep familiarity with APRA, OAIC, and Essential Eight expectations — and equally comfortable with NIST, GDPR, and global frameworks for multinational clients.
